Gas

The US is being criticized for not attending the UN Climate Change Conference in Brazil but leaders of the three largest polluters, US, China and India are not attending. China is responsible for 33% of CO2 emissions while the US comes in second at 12% and India third at 8%. Since 2005 US CO2 emissions have declined by 20% primarily by replacing coal fired power plants with natural gas. Similar reductions could be made by switching transportation from gasoline and diesel to natural gas. The US has used natural gas in trucks and buses for years. Many political leaders still believe that wind and solar can replace fossil fuels but the answer is using natural gas on the way to nuclear.
