Even if carbon dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years, according to Princeton University-led research published in the journal Nature Climate Change. The study suggests that it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.
The nonprofit National Research Council (NRC) recently issued a report on how America can reduce its petroleum, or gasoline, use and greenhouse gas emissions by vehicles by 2050.
A new software system can map greenhouse gas emissions right down to street level, and even rate particular buildings.
Human beings have been pumping methane into the atmosphere since Roman times, in enough quantity for it to show up in the Greenland ice sheet.
Human beings pumped out three percent more carbon dioxide last year than the year before, to reach an all-time high of 34 billion tonnes.
Methanol isn't new as a fuel – late in the 20th century it gained some traction, especially as a blend-in in gasoline, but it's faded since then as a transportation option.
Electric Vehicle haters may have just lost one of their major rhetorical weapons.
Dealing with the dangers of nitrous oxide in the atmosphere means not only a 50 percent cut in emissions but a 50 percent cut in meat-eating too, say scientists.
The European Cyclists' Federation has taken the trouble to calculate just how far greenhouse gas emissions could be cut if we all followed their example.
Global carbon emissions have hit a record 10 billion tons, rising by 49 per cent in the last two decades.
There's been a sharp rise in global CO2 emissions over the last ten years, despite reductions by industrialized countries.
After 2009's dip in carbon emissions caused by the world economic crisis, levels hit a record high last year.
Biofuels may not be the greenest option for airlines after all, says MIT, and can sometimes result in higher greenhouse gas emissions than traditional fossil fuels.
Where there’s heat, there’s energy - even in the smelly exhaust that emerges from a car tailpipe.
Representatives from 200 countries are gathering in Cancun for this year's UN climate summit. But hopes aren't high that there will be any global deal as a result.
The world economic recession appears to have been responsible for a fall in global emissions of carbon dioxide betweem 2008 and 2009.
You can turn down the heating; you can switch to a hybrid car. But unless you can stop, um, we'd better call it excreting, your efforts won't go a long way towards cutting your carbon emissions.
GreenPeace has expressed its concern over the iPad's rather potentially large carbon footprint.
Europe is effectively outsourcing a third of its carbon emissions overseas, according to a new study.
