Carbon capture and storage (CCS) is often promoted as a way for coal power to be made “clean”: Projects such as the in-progress Kemper power plant in Mississippi and the recently announced Petra Nova project in Texas aim to trap the carbon dioxide from burning coal and then store it into underground storage or into…

Detractors have called the U.S. Environmental Protection Agency’s proposed limits on power plant emissions onerous and unachievable, but the Union of Concerned Scientists is out with a report that does more than fend off those claims. The group says the Clean Power Plan could go much further than it does in cutting carbon, simply by properly accounting for the demonstrated…

Cutting the U.S. greenhouse gas emissions that stoke climate change could save billions in energy costs and boost revenue for the natural gas industry, according to a new report from the World Resources Institute, a research organization that advocates for environmental sustainability. The report, Seeing Is Believing, focuses on five areas that account for 55…

An area in the U.S. Southwest that’s about half the size of Connecticut has emitted the country’s largest concentration of methane, a potent greenhouse gas, according to a new analysis of satellite data. The study, which was released jointly by the American Geophysical Union and NASA, found that between 2003 and 2009, the area released…

What exactly is “the cleanest liquefied natural gas in the world?” It’s a hypothetical fuel that leaders in British Columbia, Canada, have repeatedly promised to deliver in an effort to build public support for their proposed LNG industry. But while it sounds clear-cut, it’s proven a tough nut to crack. After all, the greenhouse gases…

A top Chinese climate adviser signaled Tuesday that the country planned to set a new cap on carbon emissions by the end of the decade, which would be the first such effort from the world’s largest emitter of greenhouse gases. The comments by He Jiankun, chairman of China’s Advisory Committee on Climate Change, came a…

Natural gas emits significantly less carbon dioxide than either coal or gasoline when burned, but its ability to help reduce overall greenhouse gas emissions has been questioned. In the latest contribution to the debate, a study published this week by Duke University researchers concludes that switching to abundant shale gas as an energy source is…

After decades of debate and with growing anxiety about climate change, the planet is no closer to a systematic solution to our collective energy challenge. Yet still we try. At its impressive Vancouver gathering, National Geographic asked a simple question:  Is natural gas the bridge to a sustainable energy future?  (See video featuring participants including…

The U.S. Department of Energy has been counting on leftover residue from corn cultivation—such as  stalks and cobs—as an abundant future source of renewable clean energy, and touted it as a potential goldmine for farmers as well. But University of Nebraska-Lincoln (UNL) researchers may throw a damper on those plans, with a newly published study…

Almost all of the climate-affecting methane leaks from the oil and gas infrastructure could be reduced at relatively little expense, often by simply tightening bolts or replacing worn seals, suggests a new study by the Boston-based Clean Air Task Force released today. (See related story: “Green Fracking? 5 Technologies for Cleaner Shale Energy.”) The report…

Clean hydrogen power will soon be arriving at the Port of Honolulu in Hawaii, in a project that’s expected to help lower emissions and reduce energy consumption. Early next year, specially designed shipping containers powered by fuel cells and hydrogen will be used to keep refrigerated containers cool while they’re shipped on barges from island…

Emissions of the potent heat-trapping gas, methane, the main component of natural gas, are likely 50 percent higher than U.S. government has estimated in its official greenhouse gas inventory, says a new study that is the most comprehensive effort yet to assess the problem. But the team of scientists, after reviewing more than 200 earlier…

Our cities have the potential to be a key climate change solution. Already they are hot-beds of innovation in local and global approaches to the nexus of sustainability and quality of life.  People who live in cities drive less, use less energy to heat, cool, and light their homes, and even their water and sewer…

A new study challenges our understanding of natural gas as a clean fuel, and raises new questions about the U.S. energy boom. Sure, natural gas (or methane, its main component) burns with less pollution than coal, but release it directly to the atmosphere and it is a highly potent greenhouse gas–at least 25 times worse…

At climate change talks in Warsaw this week, just as in the previous 18 annual rounds of negotiations, delegates never were able to overcome the divide between rich and poor nations. We map the starkly different views of the climate crisis that have led to stalemate in our newly revised interactive, Four Ways to Look…

Big Bend National Park is known for its beauty — and its haze problem. So it might come as a surprise to some that it recently earned the designation of a Gold Tier International Dark Sky Park. The designation makes the 801,000-acre (324,153-hectare) West Texas park, which borders the Rio Grande, one of only 10…

Green Growth or Green Confusion?

I have just been at the inaugural Global Green Growth Forum (3GF) in Copenhagen. This was a high level event, opened by the Crown Prince of Denmark and the new Danish Prime Minister, then following the initial panel discussion there was an introductory keynote by United Nations Secretary General Ban Ki-Moon – in person. The…

It is not widely discussed, but the United States does, in fact, have a greenhouse gas emissions reduction target. In the heady days of January 2010 after the Copenhagen Climate Conference, many nations put pen to paper and wrote to the UNFCCC pledging to reduce emissions by 2020 relative to some baseline. This was a…
