Brazil has withdrawn its offer to host a large U.N. conference on climate change next year, the foreign ministry said on Wednesday, leading environmental groups to question the government's commitment to reducing carbon emissions.
UN Secretary-General Ban Ki-moon welcomed the announcement by the International Civil Aviation Organization (ICAO) proposing the first binding limits on emissions from the aviation industry.
The United States Environmental Protection Agency's new regulations aimed at reducing carbon emissions by 30% will no doubt lead to a cleaner economy. But the road there will be paved with methane. By requiring reductions in the energy intensity per megawatt-hour of electricity generation, utilities will have the ability to choose from an array of options for how to meet the targets.
