WITH much fanfare, US President Barack Obama took to the White House podium to announce, as part of his administration’s action plan on climate change, a new Clean Power Plan aimed at cutting carbon emissions from electricity generation in the US, chiefly from coal-based power plants, by 32 percent below 2005 levels by 2030. The Plan, comprising a set of rules proclaimed by the federal Environment Protection Agency (EPA) under the Clean Air Act, seeks to shut down or drastically improve efficiencies of coal-based power stations and promote non fossil-fuel electricity generation.
