Britain plans to start phasing out incandescent lightbulbs starting next year in an attempt to save energy and help fight against climate change.

A Climate Change Bill is expected to be released by the British government and may lead to legally-binding commitments. The proposed target is a 60% reduction in carbon dioxide by 2050.

Britain’s new science adviser is calling for the development of green technologies to combat climate change. Big emitters like China and India also need to be encouraged to use clean coal technology, he says.

Many countries around the world are striving towards a lighter footprint. The publication “The Hot Topic: How To Tackle Global Warming And Still Keep The Lights On,” by Sir David King, the British Government’s chief science adviser, and academic Gabrielle Walker looks at some success stories around the world including Japan, France, Germany, Britain, Austin (Texas), Newcastle (UK) and Western Cape province (South Africa).
