Dozens of protesters camped out on the roof of Britain's parliament overnight to "save the climate," police reported Monday. More than 50 protesters climbed onto the roof of Westminster Hall at about 3 p.m. (10 a.m. ET) on Sunday, police said, and 31 remained on the roof as of Monday morning, environmental group Greenpeace said. About two dozen came down voluntarily and were arrested on suspicion of trespassing Sunday night, both sides said. Police put the number at 23 while ...

Like many things in Japan, the message is subtle. At least Japan's All Nippon Airways hopes it is, now that the nation's second largest airline has started quietly asking passengers in Japanese to use the bathroom before boarding 38 domestic flights and four international flights between Tokyo and Singapore. The request is part of the airline's "ecological flight" program, now in its fourth year, to reduce its carbon footprint by lightening planes' loads and reducing fuel consumption. Through ...

The unveiling Wednesday morning of the Senate's long-awaited draft legislation to reduce U.S. carbon emissions and shift the country to a clean-energy economy signals that Washington is inching ever closer to addressing global warming. The sweeping bill, sponsored by Democratic Sens. Barbara Boxer and John Kerry, will cut U.S. greenhouse gas emissions 20% below 1990 levels by 2020, and 83% by 2050 — targets that in the short-term are a bit more ambitious than a similar carbon cap and ...

Chinese President Hu Jintao told a U.N. summit on climate change Tuesday that China will reduce greenhouse gas emissions and increase reliance on clean energy sources in coming years. In what was called the first speech on climate change by a Chinese leader at the United Nations, Hu outlined some specific steps but provided no firm target for reducing greenhouse gas emissions that cause global warming. As one of the world's two largest greenhouse gas emitters, China is a major ...

New fuel-economy rules proposed by the federal Department of Transportation and the Environmental Protection Agency are the first major move by the U.S. toward cracking down on greenhouse-gas emissions. The proposed program includes miles-per-gallon requirements and national emissions standards under the EPA's greenhouse-gas-emissions guidelines for model years from 2012 to 2016. You'd think that environmental groups would be overjoyed. Hardly. What has them worried are all the pro-industry rule tweaks and what they see as slanted calculations. "Automakers ...

When Apollo astronauts Neil Armstrong and Buzz Aldrin landed on the moon 40 years ago, it was a triumph of American scientific skill. It was also the result of the government's willingness to spend over $125 billion, in today's dollars, to take the country to the moon. The need to remake our energy economy and to replace fossil fuels with renewables like wind and solar is often referred to as the new Apollo Project, a challenge to our scientists ...

Got a few grand to spare for a $3,000 phone? Yeah, we didn't think so. Nobody does -- and that's a problem for the makers of luxury phones, such as Motorola, Bang & Olufson, LG and Vertu. After years of chasing the ultra-wealthy with exclusive devices that carry designer logos and promise craftsmanship from materials such as sapphire and stainless steel, luxury phone makers are now pulling back. "The culture has shifted away from conspicuous consumption, so if you are ...

Microsoft had trouble solving the problems with its Vista operating system, so what are its chances of fixing climate change? The global software firm has created an online tool called Project 2 Degrees for cities across the world to monitor their greenhouse gas (GHG) emissions and, the hope is, then do something about them. While Bill Gates' company have tailored an online carbon accounting tool for cities, businesses are increasingly turning on to the benefits and need to ...

Tendai Biti is Zimbabwe's outspoken finance minister and MDC party Secretary General. The 44-year-old lawyer has openly criticized president Mugabe and his government, but was the main negotiator in forging a coalition government. As well as working with his political enemy, he now has the daunting task of rebuilding a collapsed economy that had an inflation rate of 500 billion percent in December 2008 and and unemployment at 95 percent. The global software firm has created an online tool ...

Twenty milligrams; that's the average amount of carbon emissions generated from the time it took you to read the first two words of this article. Now, depending on how quickly you read, around 80, perhaps even 100 milligrams of C02 have been released. And in the several minutes it will take you to get to the end of this story, the number of milligrams of greenhouse gas emitted could be several thousand, if not more. This may not ...
