Obama to regulate ‘pollutant’
Richard Black
Environment correspondent, BBC News website
The US government is to regulate carbon dioxide emissions, having decided that it and five other greenhouse gases may endanger human health and well-being.
The Environmental Protection Agency (EPA) announced the move following a review of the scientific evidence.
The decision marks a major change from the Bush presidency, when the EPA argued it could not regulate CO2 because the gas was not a pollutant.
Developing countries have asked for the US to show leadership on climate.
