* Funds to develop efficient engines, low-cost motorcycles

* To spend total 202 bln yen on R&D in three years to 2012

TOKYO, April 2 (Reuters) – Japanese motorcycle maker Yamaha Motor Co (7272.T) said it will raise up to 76.1 billion yen ($812 million) in a share sale to finance the development of fuel-efficient engines and low-cost bikes for emerging markets.

Hit by a demand slump in the United States and Europe, as well as restructuring costs, Yamaha booked a hefty net loss of 216 billion yen in 2009 and aims to break even this year.

The offering will mark the largest equity-based fund raising by a company in the auto sector since Mazda Motor’s (7261.T) deal to procure 98 billion yen in October last year.

Players in the auto market have entered into a costly race to cope with the demand plunge in the United States, the world’s largest market, as well as a shift in customer appetite towards environmentally-friendly products, including hybrid and electric vehicles.

Yamaha said it will develop more fuel-efficient engines for motorcycles and boats to improve the competitiveness of its products, as well as electric motorcycles and motor-assisted bicycles, for which demand is seen rising.

This is the first equity fund-raising by Yamaha since it raised 40.3 billion yen in May 2007.

The company said in a statement on Friday that it would issue up to 63.25 million shares, including a greenshoe option of 8.25 million shares. The public offering could increase its total number of shares outstanding by 22 percent.

Nomura Securities, a unit of Nomura Holdings (8604.T), will manage the sale, Yamaha said.

The firm said it would spend a total of 202 billion yen on research and development in the three years to 2012 to help achieve growth in emerging and ASEAN countries and to accelerate the development of environmentally-friendly engines.

It spent 62 billion yen on research and development in 2009 and has budgeted 60 billion yen for the current year.

Under its recently compiled mid-term business plan, the company aims to raise its annual revenues to 1.4 trillion yen by 2012 from 1.15 trillion yen in 2009, although that would still be short of the 1.6 trillion yen achieved in 2008. (Reporting by Yumiko Nishitani; Editing by Joseph Radford

Despite IAEA findings, Iran sings its old nuke-for-peaceful-purposes tune

Tehran, Sep. 18 (ANI): Even as a secret IAEA report revealed that Iran is capable of making a nuclear bomb and is developing a missile system to carry an atomic warhead, Iranian officials have reiterated claims that the Islamic nation’s nuclear program is intended for peaceful purposes.

Fox News quoted Iran’s ambassador to the International Atomic Energy Agency, Ali Asghar Soltanieh, as saying that Iran is sincere in wanting to negotiate with the West.

He added that Western countries should “read between the lines” about Iran’s intentions.

Although the prospects of finding anything between the lines were almost nil after the surfacing of the IAEA report, but Soltanieh insisted that discussions with the West would be a “real, new window of opportunity.”

The secret U.N. watchdog report, titled “Possible Military Dimension of Iran’s Nuclear Program,” concludes:

*Iran worked on developing a chamber inside a ballistic missile capable of housing a warhead payload “that is quite likely to be nuclear.”

*Iran engaged in “probable testing” of explosives commonly used to detonate a nuclear warhead – a method known as a “full-scale hemispherical explosively driven shock system.”

*Iran worked on developing a system “for initiating a hemispherical high explosive charge” of the kind used to help spark a nuclear blast.

“Iran has sufficient information to be able to design and produce a workable implosion nuclear device (an atomic bomb) based on HEU (highly enriched uranium) as the fission fuel,” The agency assessed.

On October 1, Iran is scheduled to meet with the U.S. and five other world powers seeking curbs on its atomic activities for the first time in more than a year.

However, Tehran says it is not prepared to discuss its nuclear activities. (ANI)

Catalyst simulations for fuel cells may make clean cars a reality

Washington, Sep 18 (ANI): University of Wisconsin-Madison researchers are working towards developing better catalyst for fuel cells in a bid to make clean cars a reality.

If successful, the researchers could make a car that runs on hydrogen from solar power, and produces water instead of carbon emissions.

Materials science and engineering assistant professor Dane Morgan and Ph.D. student Edward (Ted) Holby have developed a computational model that could optimise an important component of fuel cells, making it possible for the technology to have a more widespread use.

The researchers investigated how particle size is related to the overall stability of a material, and showed with their model that increasing the particle size of a fuel cell catalyst decreases degradation and therefore increases the useful lifetime of a fuel cell.

Fuel cells are electrochemical devices that facilitate a reaction between hydrogen and oxygen, producing electrical power and forming water.

In the type of fuel cells Morgan is researching, called proton exchange membrane fuel cells (PEMFCs), hydrogen is split into a proton and electron at one side of the fuel cell (the anode).

The proton moves through the device while the electron is forced to travel in an external circuit, where it can perform useful work, while at the other side of the fuel cell (the cathode), the protons, electrons and oxygen combine to form water, which is the only waste product.

One of the many hurdles to producing efficient fuel cells for widespread use is the catalyst added to aid the reaction between protons, electrons and oxygen at the cathode.

Current fuel cells use platinum and platinum alloys as a catalyst. While platinum can withstand the corrosive fuel cell environment, it is expensive and not very abundant.

Thus, to maximize platinum use, researchers use catalysts made with platinum particles as small as two nanometers, which are approximately 10 atoms across.

These tiny structures have a large surface area on which the fuel cell reaction occurs.

However, platinum catalysts this small degrade very quickly, which means that the fuel cell doesn’t last long.

The researchers have found a possible solution to the rapid degradation problem-when it comes to catalyst particle size, sometimes smaller isn’t better.

In their modelling work, they showed that if the particle size of a platinum catalyst is increased to four or five nanometers, which is approximately 20 atoms across, the level of degradation significantly decreases.

This means the catalyst and the fuel cell as a whole can continue to function for much longer than if the particle size was only two or three nanometers.

“Fuel cells are just one of many energy technologies – solar, battery, etc. – with enormous potential to reduce our dependence on oil and our carbon emissions. Computer simulation offers a powerful tool to understand and develop new materials at the heart of these energy technologies,” said Morgan. (ANI)

Taliban now terrorise 80% of Afghanistan after eight years of war: Report

Kabul, Sep. 11 (ANI): Almost eight years after the war began in Afghanistan in the aftermath of the 9/11 carnage, the Taliban insurgency has spread across 80 percent of the country.

The violent incidents this week have drawn attention to the deteriorating security situation of northern Afghanistan, which had largely remained peaceful so far, the Christian Science Monitor reports.

The northern provinces are facing difficult times as heavy insurgent activity has spread to 80 percent of the country – up from 54 percent two years ago, the report says.

The militants’ focus has shifted to northern parts following continuous pressure from their Pakistani counterparts to attack NATO’s second supply route situated here, it adds.

“[Militants] have been trying to widen the ground for the insurgency in Afghanistan and now they have got momentum. The militants are eager to target this route to prevent a smooth supply chain from northern Afghanistan,” the report quoted Waliullah Rahmani, executive director of the Kabul Center for Strategic Studies, as saying.

Last week’s airstrike targeted two fuel tankers headed to supply NATO troops in Kabul that had been hijacked by the Taliban.

Although the increase in violence is only a recent phenomenon, the conditions had worsened long ago, the report says.

The violence can be linked to districts with large Pashtun populations, whose grievances the government has failed to address – making them sympathetic to the Taliban, who share their ethnicity and language, it adds.

“The districts which are turning violent are those which have had a very recent history of abuses against the Pashtuns.

The government has allowed these conditions to go unaddressed and this is now being addressed by the population by giving shelter to the Taliban and other insurgents,”the report quoted Prakhar Sharma, the head of research at the Center for Conflict and Peace Studies, as saying.(ANI)

US accepts Iranian offer to hold discussions

Washington, Sep. 11 (ANI): The United States has accepted Iran’s proposal to hold talks, despite the Islamic republic announcing that it would not bring its future nuclear programs on the discussions table.

The decision to engage directly with Iran would put a senior representative of the Obama administration at the bargaining table, along with emissaries from five other nations, for the first time since Obama took office, the New York Times reports.

The decision is bound to raise protests from conservatives and human rights groups.

Earlier on Friday, senior administration officials said that their expectations from the talks were extremely low.

“We’ll be looking to see if they are willing to engage seriously on these issues. If we have talks, we will plan to bring up the nuclear issue,” paper quoted US State Department spokesman Philip J. Crowley, as saying.

They added that the United States could make a case for imposing far stronger sanctions on Iran if diplomatic engagements fail.

Britain, France, Russia, China and Germany are going to be present on the discussion table, who in the past have negotiated with Iran even without the presence of an American representative.

Iran made its offer to meet in a five-page letter delivered to several nations on Wednesday.

But the letter said nothing about Iran’s nuclear program. However, this week Iranian President Mahmoud Ahmadinejad vowed never to halt the fuel production.

Within less than 48 hours the Obama administration said they would consider the offer to meet.

Even though it is unclear who will represent the US on the discussion table, but most probably William J. Burns, the under secretary of state for political affairs, will lead America.

Earlier, Burns was quoted as saying that the Obama administration had begun preparing sanctions against Iran, so that it would be ready to implement them at the end of the year. (ANI)

Moblies, digital cameras to feature in new WPI list

New Delhi, Sep. 8 (ANI): Moblie phones and digital cameras are among the 300 new items, which would figure in the new Wholesale Price Index (WPI).

Over 30 items would be taken off the new inflation series, which is expected to be out by December. Existing series has many obsolete items. They will not figure in the new series. There will be 25-30 articles which you will not see in the new index we are compiling,” an official said.

Most of the addition would be in the manufacturing products category and the primary items, which consist of food grains and milk, would remain unchanged, the official added.

There could be minor changes in the fuel, power light and lubricant group.

With the addition of new items, data reporting would be more representative and give a better picture of the price situation, he said.

The base year for the new index will be 2004-05 while the WPI is presently calculated on 1993-94 base.

The Department of Industrial Policy and Promotion (DIPP), which brings out the inflation data, has started a trial run of the new index and data is being collected.

In the trail index, data for 1,100 items are being collected, which would be eventually consolidated to about 700 articles, the official said.

In the existing series, the weight of primary articles is 22.02 per cent while manufactured products contribute 63.75 per cent.

The weight of fuel, power, light and lubricants in the index is about 14 per cent. (ANI)

Four-member team set up to probe Air India fire incident

Mumbai, Sep 5 (ANI): A four-member in-house committee has been set up to probe the Air India fire incident that took place at Mumbai International Airport on Friday.

Nearly 200 passengers were onboard on Riyadh bound Air India flight (AI-829) while the aircraft’s left engine caught fire while taking off.

Many passengers suffered bruises and cuts while sliding down from the chutes but were taken to the Mumbai International Airport Pvt Ltd (MIAL) casualty centre and given first aid.

Ruling out the possibility of a technical snag leading to the grounding of the aircraft at Mumbai Airport, aviation experts said the fuel leaked onto the heated engines of the aircraft and that had caused the fire.

They said that timely information provided by a passenger led the crew to stop the flight from taxing off the runway for Saudi Arabian capital Riyadh.

Flight 829 was immediately grounded when sparks were detected flying out of one of the engines.

The 213 passengers onboard were evacuated by slides to safety. Four fire engines were rushed to the spot, as also other equipment and personnel. (ANI)

DGCA recommends derostering of Air India maintenance engineer for fuel leak

Mumbai, Sep.4 (ANI): The Directorate General of Civil Aviation (DGCA) has ordered the derostering of the maintenance engineer who was working on Air India flight 829 after it developed a fuel leak.

The DGCA has ordered a detailed probe into the fuel leak from the wings of an Air India flight that caused one of the engines to catch fire.

Ruling out the possibility of a technical snag leading to the grounding of the aircraft at Mumbai Airport on Friday morning, aviation experts said the fuel leaked onto the heated engines of the aircraft and that had caused the fire.

Had it not been detected, they said it could have led to a major catastrophe in the air.

Climate change mitigation strategies ignore carbon cycling processes of inland waters

Washington, Sept 2 (ANI): In a new report, scientists have determined that climate change mitigation strategies ignore carbon cycling processes of inland waters.

Scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the US based Stroud Water Research Center, authored the report, which is published in the September issue of Nature Geoscience.

They argue that current international strategies to mitigate manmade carbon emissions and address climate change have overlooked a critical player – inland waters.

Streams, rivers, lakes, reservoirs, and wetlands play an important role in the carbon cycle that is unaccounted for in conventional carbon cycling models.

According to Dr. Tom J. Battin of the department of Freshwater Ecology at the University of Vienna and lead author of the report, “While inland waters represent only 1 percent of the Earth’s surface, their contribution to the carbon cycle is disproportionately large, underestimated, and not recognized within the models on which the Kyoto protocol was based.”

The team of scientists points out that all current global carbon models consider inland waters static conduits that transfer carbon from the continents to the oceans.

In reality, inland waters are dynamic ecosystems with the potential to alter the fates of terrestrial carbon delivered to them including: burial in sediments leading to long-term storage or sequestration; and metabolism in rivers and subsequent outgassing of respired carbon dioxide to the atmosphere.

“Twenty percent of the continental carbon sequestration actually occurs as burial in inland water sediments,” said Dr. Lars Tranvik, Professor of Limnology at Uppsala University in Sweden.

“River outgassing of respired carbon, contributes carbon to the atmosphere in an amount equivalent to 13 percent of annual fossil fuel burning,” said Dr. Anthony K. Aufdenkampe, a scientist at the Stroud Water Research Center.

Because the amount of atmospheric carbon is well known and conservation of matter requires a balanced global carbon budget, this previously unaccounted for source of carbon to the atmosphere implies the existence of an additional continental carbon sink such as higher rates of biomass accrual in forests.

“A larger accumulation of carbon in forest ecosystems that could offset the outgassing from rivers would be more consistent with current independently-derived estimates of carbon sequestration on the continents,” said Dr. Sebastian Luyssaert of the department of Biology at University of Antwerp in Belgium.

Increasing residential and employment density may reduce vehicle travel, fuel use and CO2

Washington, Sept 2 (ANI): A new report has determined that increasing population and employment density in metropolitan areas could reduce vehicle travel, energy use, and CO2 emissions from less than 1 percent up to 11 percent by 2050.

The report is a new congressionally mandated report from the National Research Council in the US.

Assuming compact development is focused on new and replacement housing, as converting existing housing to higher densities could be prohibitively difficult, significant increases in density would result in modest short-term reductions in personal travel, energy use, and CO2 emissions.

However, these reductions will grow over time.

According to the committee that wrote the report, the most reliable research studies estimate that doubling residential density in a metropolitan area might lower household driving between 5 percent and 12 percent.

If higher density were paired with more concentrated employment and commercial locations, and combined with improvements to public transit and other strategies to reduce automobile travel, household driving could be lowered by as much as 25 percent.

By reducing vehicle use, petroleum use and CO2 emissions would also be lessened.

In order to quantify the potential effects of compact development, the committee developed illustrative scenarios, looking forward to 2030 and 2050.

If 75 percent of new and replacement housing units in the US were developed at twice the density of current new development, and individuals drove 25 percent less – the committee’s upper-bound scenario – personal travel, fuel use, and CO2 emissions would be reduced by 7 percent to 8 percent, relative to a base case, by 2030, and by 8 percent to 11 percent by 2050.

If only 25 percent of housing units were developed more compactly, and residents drove 12 percent less, then personal travel, fuel use, and CO2 emissions would be reduced by approximately 1 percent by 2030, and by 1.3 percent to 1.7 percent by 2050.

If in this lower-bound scenario, residents drove only 5 percent less, then personal travel, fuel use, and CO2 emissions would be reduced by less than 1 percent by 2050. (ANI)

‘Toxic cocktail’ in tunnels can increase air pollution levels by up to 1,000 times

Washington, August 28 (ANI): A new study has found that a toxic cocktail of ultrafine particles, which is lurking inside road tunnels, can increase air pollution levels by up to 1,000 times, enough to harm drivers and passengers.

The study measured ultrafine particle concentration levels outside a vehicle travelling through the M5 East tunnel in Sydney.

According to study co-author and director of Queensland University of Technology’s International Laboratory for Air Quality and Health, Professor Lidia Morawska, road tunnels were locations where maximum exposure to dangerous ultrafine particles in addition to other pollutants occurred.

“The human health effects of exposure to ultrafine particles produced by fuel combustion are generally regarded as detrimental,” Professor Morawska said.

“Effects can range from minor respiratory problems in healthy people, to acute myocardial infarction (heart attack) in people with existing heart complaints,” she added.

Professor Morawska said the study involved more than 300 trips through the four kilometres of the M5 East tunnel, with journeys lasting up to 26 minutes, depending on traffic congestion.

“What this study aimed to do was identify the concentration levels found in the tunnel. It generated a huge body of data on the concentrations and the results show that, at times, the levels are up to 1000 times higher than in urban ambient conditions,” she said.

She said that drivers and occupants of new vehicles which had their windows closed were safer than people travelling in older vehicles.

“People who are driving older vehicles which are inferior in terms of tightness and also those riding motorcycles or driving convertibles, these people are exposed to incredibly high concentrations,” she said.

“When compared with similar studies reported previously, the measurements here were among the highest recorded concentrations,” she added.

Professor Morawska said that tunnels were becoming an increasingly necessary infrastructure component in many cities across the world.

“When governments are building tunnels for urban design reasons, they should also consider the impact these tunnels are having on the environment and to people’s health,” she said.

“The study highlights why governments need to consider how they are going to deal with the air pollution levels inside the tunnel and removal of ultrafine particles in the outside environment,” she added. (ANI)

Unique acacia tree could nourish soils in Africa

Washington, August 25 (ANI): In a new research, scientists have said that a type of acacia tree with an unusual growth habit, which is unlike virtually all other trees, holds particular promise for farmers in Africa as a free source of nitrogen for their soils that could last generations.

With its nitrogen-fixing qualities, the tall, long-lived acacia tree, Faidherbia albida could limit the use of fertilizers; provide fodder for livestock, wood for construction and fuel wood, and medicine through its bark, as well as windbreaks and erosion control to farmers across sub-Saharan Africa.

According to scientists, the tree illustrates the benefits of growing trees on farms and is adapted to an incredibly wide array of climates and soils from the deserts to the humid tropics.

“Growing the right tree in the right place on farms in sub-Saharan Africa-and worldwide- has the potential to slow climate change, feed more people, and protect the environment,” said Dennis Garrity, Director General of the World Agroforestry Centre.

“This tree, as a source of free, organic nitrogen, is an example of that. There are many other examples of solutions to African farming that exist here already,” he added.

The Faidherbia acacia tree has the quality of “reverse leaf phenology,” which drives the tree to go dormant and shed its nitrogen-rich leaves during the early rainy season – when seeds are being planted and need the nitrogen – and then to re-grow its leaves when the dry season begins and crops are dormant.

This makes it highly compatible with food crops because it does not compete with them for light-only the bare branches of the tree’s canopy spread overhead while crops grow to maturity.

Their leaves and pods provide a crucial source of fodder in the dry season for livestock when other plants have dried up.

The unique acacia tree is a frequent component of farming systems of Senegal, Mali, Burkina Faso, Niger, Chad, Sudan, and Ethiopia, and in parts of northern Ghana, northern Nigeria, and northern Cameroon.

The tree is growing on over 4.8 million hectares of land in Niger. Half a million farmers in Malawi and in the southern highlands of Tanzania grow the tree on their maize fields.

In Malawi, maize yields were increased up to 280 percent in the zone under the tree canopy compared with the zone outside the tree canopy.

In Zambia, recent unpublished observations showed that unfertilized maize yields in the vicinity of the Faidherbia trees averaged 4.1 tonnes per hectare, compared to 1.3 tonnes nearby but beyond the tree canopy. (ANI)

NASA successfully tests eco-friendly rocket propellant

Washington, August 22 (ANI): NASA and the Air Force Office of Scientific Research, or AFOSR, have successfully launched a small rocket using an environmentally-friendly, safe propellant comprised of aluminum powder and water ice, called ALICE.

“This collaboration has been an opportunity for graduate students to work on an environmentally-friendly propellant that can be used for flight on Earth and used in long distance space missions,” said NASA Chief Engineer Mike Ryschkewitsch at NASA Headquarters in Washington.

“These sorts of university-led experimental projects encourage a new generation of aerospace engineers to think outside of the box and look at new ways for NASA to meet our exploration goals,” he added.

Using ALICE as fuel, a nine-foot rocket soared to a height of 1,300 feet over Purdue University’s Scholer farms in Indiana earlier this month.

ALICE is generating excitement among researchers because this energetic propellant has the potential to replace some liquid or solid propellants.

When it is optimized, it could have a higher performance than conventional propellants.

“By funding this collaborative research with NASA, Purdue University and the Pennsylvania State University, AFOSR continues to promote basic research breakthroughs for the future of the Air Force,” said Dr. Brendan Godfrey, director of AFOSR.

ALICE has the consistency of toothpaste when made. It can be fit into molds and then cooled to -30 degree Celsius 24 hours before flight.

The propellant has a high burn rate and achieved a maximum thrust of 650 pounds during this test.

“A sustained collaborative research effort on the fundamentals of the combustion of nanoscale aluminum and water over the last few years led to the success of this flight,” said Dr. Steven F. Son, a research team member from Purdue.

“ALICE can be improved with the addition of oxidizers and become a potential solid rocket propellant on Earth. Theoretically, ALICE can be manufactured in distant places like the moon or Mars, instead of being transported to distant locations at high cost,” he added. (ANI)

Scientists come closer to ‘synthetic life’ in lab

London, Aug 21 (ANI): A group of scientists has created a new “engineered” strain of bacteria – a development which could be described as a step towards the creation of “synthetic life”.

The team, including scientist J Craig Venter, a leading figure in the controversial field of synthetic biology, has successfully transferred the genome of one type of bacteria into a yeast cell, modified it, and then transplanted into another bacterium.

The study paves the way to the creation of a synthetic organism – inserting a human-made genome into a bacterial cell.

It has been described in the journal Science.

According to boffins, the advancement overcomes the obstacle of making a new inserted genome work inside a recipient cell.

The resulting cell Sanjay Vashee, one of the authors, and his team created went on to undertake multiple rounds of cell division, to produce a new strain of the modified bacteria.

Vashee is a researcher at the J. Craig Venter Institute in Rockville, Maryland, in the US. He explained to BBC News: “Bacteria have ‘immune’ systems that protect them from foreign DNA such as those from viruses.”

The scientists disabled the immune system, which consists of proteins called restriction enzymes that home in on specific sections of DNA and chop up the genome at these points.

Bacteria can shield their own genomes from this process by attaching chemical compounds called methyl groups at the points which the restriction enzymes attack.

The scientists modified the original genome of the bacterium Mycoplasma mycoides, whilst it was inside the yeast cell. Then they either attached methyl groups to it, or inactivated the restriction enzyme of the recipient bacterium, before transplanting the genome into its new cell.

The team aims to transplant a fully synthetic genome into a bacterial cell – creating bacteria that can be programmed to carry out specific functions – for example, digesting biological material to produce fuel. (ANI)

US navy chemists try to turn seawater into jet fuel

London, August 19 (ANI): In a new experiment, US navy chemists have processed seawater into unsaturated short-chain hydrocarbons that with further refining could be made into kerosene-based jet fuel.

According to a report by New Scientist, the process involves extracting carbon dioxide (CO2) dissolved in the water and combining it with hydrogen – obtained by splitting water molecules using electricity – to make a hydrocarbon fuel.

It uses a variant of a chemical reaction called the Fischer-Tropsch process, which is used commercially to produce a gasoline-like hydrocarbon fuel from syngas, a mixture of carbon monoxide and hydrogen often derived from coal.

Robert Dorner, a Naval Research Laboratory chemist in Washington DC and first author of a new paper on the technique, said that CO2 is rarely used in the Fischer-Tropsch process because of its chemical stability.

“But CO2′s abundance, combined with concerns about global warming, make it an attractive potential feedstock,” Dorner said.

“Although the gas forms only a small proportion of air – around 0.04 per cent – ocean water contains about 140 times that concentration,” he added.

The navy team has been experimenting to find out how to steer the CO2-producing process away from producing unwanted methane to produce more of the hydrocarbons wanted.

In the conventional Fischer-Tropsch process, carbon monoxide and hydrogen are heated in the presence of a catalyst to initiate a complex chain of reactions that produce a mixture of methane, waxes and liquid fuel compounds.

Dorner and colleagues found that using the usual cobalt-based catalyst on seawater-derived CO2 produced almost entirely methane gas.

Switching to an iron catalyst resulted in only 30 per cent methane being produced, with the remainder short-chain hydrocarbons that could be refined into jet fuel.

According to Heather Willauer, the navy chemist leading the project, the efficiency needs to be much improved, perhaps by finding a different catalyst. (ANI)

Steel Minister asks SAIL to complete all expansion plans on time

New Delhi, Aug 18 (ANI): Union Steel Minister Virbhadra Singh on Tuesday asked the Steel Authority of India (SAIL) to complete all the ongoing expansion programmes on time.

He was reviewing the Q1 performance of the public sector major at a meeting here today.

He said, the economy looks set for a rebound considering the latest IIP numbers and the projections of GDP this fiscal. This will translate into decent demand growth for steel in the near future.

The Minister appreciated the difficult business environment following the slowdown and hoped the situation to improve in the next couple of quarters.

He expressed satisfaction over the performance of SAIL during the first quarter.

The steel major reported a turnover of Rs 9747 crore during April-June 09, a decrease of 20 per cent over the same quarter last year. The net profit also fell by 27.7 per cent to Rs.1326 crore.

Singh urged the SAIL to strengthen its CSR activities.

“Out of the budget of Rs. 80 crore, the company has been able to spend Rs10.83 crore during the first quarter which is a drop of 201 per cent on sequential basis and a drop of 60 per cent compared to Q1 of the previous year,” he said.

The profitability was adversely affected due to reduction in average net sales realization of saleable steel, escalation in input prices mainly of imported coal, coke, ferro-silicon, increase in railway freight, increase in fuel cost surcharge by DVC and higher interest charges. (ANI)

China’s carbon emissions may peak around 2030

New Delhi, August 18 (ANI): A panel of experts have determined that China’s carbon emissions output could peak around 2030 if the government continues to be serious about “strengthened measures” to improve energy efficiency and if it accelerates exploration of renewable energy.

According to the panel from the National Development and Reform Commission and the Development Research Center of the State Council, with the right policies, emissions growth could slow after 2020, with a peak around 2030.

This is the first time a Chinese think-tank has officially announced when it thinks China’s carbon emissions will peak.

The international community has closely watched the country’s carbon emissions curve because China and the US are the top two carbon emissions countries in the world.

The panel has advised China to invest significantly in low-carbon technology research and development, saying the strategy of developing such technology is “a stone killing two birds”.

“Only by using advanced low-carbon technologies can China’s greenhouse gas emissions peak around 2030; otherwise, the peak will be delayed and we don’t want to see the latter scenario,” said Jiang Kejun, a leading economist of the panel.

If the peak happens around 2030, the huge investment in low-carbon technologies could keep China’s economy growing at a fast pace and make China a global leader in cutting-edge technologies.

“I think China will become a major supplier of nuclear, wind and hydropower technologies and electricity transmission by 2030,” said Jiang. “And that should be a strategic goal for the Chinese government to pursue,” he added.

If China can achieve these goals, by 2050, its carbon emissions from fossil fuel “could fall to the same emissions levels as in 2005 or even lower”, the report said.

Jiang said that the Chinese government has been “on the right track” in making policy decisions to develop low-carbon technologies as new economic growth engines while countries worldwide are working on a plan by October to replace the Kyoto Protocol, which is set to expire in 2012. (ANI)
