By Gerard Wynn LONDON (Reuters) - Threats of retaliation by China and India against a European Union plan to charge airlines for their carbon emissions is misplaced, given their weak legal case and a drift towards more such unilateral climate action.

Countries in Durban at the end of last year topped off years of lumbering U.N

Previous studies have vastly underestimated the carbon footprint of the Canadian oil sands by not considering the industry's impact on peatlands, according to new research. [More]

DURBAN, South Africa--My share of the carbon dioxide my flight to Johannesburg emitted over 15 hours amounted to 1,391.3 kilograms, according to the helpful information provided by South African Airlines. Add a dollop of 53.8 kilograms of CO2 for the jet jaunt to Durban and you can see that the aviation industry--and the Durban climate talks --have an emissions problem.

You may remember when credit card machines weren't so reliable, so stores sometimes used that little aluminum contraption with a roller over your card, and you had to sign the printed copy hard enough to ink onto the carbon paper. This is one of the reasons some cards still have those raised silver numbers on the front alongside your name and expiration date.

Branson thinks that by being in space, people become more passionate about the planet. And he's planning on helping out cash-strapped NASA with its research, too. Earlier this week, Virgin Galactic --the space travel arm of the Virgin Group--debuted the first-ever spaceport in New Mexico

Steve Jobs created innovative products that change the world of technology. Imagine the other industries he could have disrupted

Despite a string of funding challenges in the past year, the picture is not bleak for the carbon capture and sequestration industry. That message is in a new report being released this morning from the Global CCS Institute, an Australia-based organization that studies the industry

It may be responsible for the financial meltdown, but while it was writing bad mortgages, Bank of America was also doing excellent work reducing its footprint. There are lot of problems in the world, and myriad ways to fix them. It's almost impossible to address them all at the same time.

CANBERRA (Reuters) - Australia's parliament endorsed the world's first national scheme that regulates the creation and trade of carbon credits from farming and forestry on Monday, to complement government plans to put a price on carbon emissions from mid-2012. The laws, the first major bills passed by the government with Greens support in the Senate since the Greens took the balance of power on July 1, are a precursor to the carbon price legislation to be put before parliament later this year.

In addition to knowing your exact route and even how many calories you've burned, you can now find out the environmental impact of every public transit trip you take--and how much better it is than if you had taken a car. City living just got a little more smug

Growing cellulosic feedstocks on federally subsidized conservation land could balance the biofuels emissions equation to be completely carbon-neutral, a study suggests.

WASHINGTON (Reuters) - New York Mayor Michael Bloomberg joined with the Sierra Club on Thursday in a $50 million, four-year plan to campaign for replacing one-third of aging U.S. coal-fired power plants with clean energy. "If we are going to get serious about reducing our carbon footprint in the United States, we have to get serious about coal," Bloomberg, founder of the news service that bears his name, said in a statement.

A new study shows using iron to fertilize marine plants fundamentally alters seafloor ecosystems. But that might be worth it to slow climate change. “Give me half a tanker of iron, and I’ll give you an ice age,”

UNITED NATIONS -- They are the carbon offsetting projects most hated by environmentalists, but there may now be an opportunity to put an end to them. Currently, there are five coal-fired power plants registered as emission reduction projects under the Clean Development Mechanism (CDM), an international offsetting program run by an arm of the United Nations. Pressure from developing nation governments led to their inclusion in the program, as supporters claim the newer supercritical coal plants avoid carbon dioxide emissions by preventing dirtier plants from being built instead.
