Most ready for 'green sacrifices'

Most people are ready to make personal sacrifices to address climate change, according to a BBC poll of 22,000 people in 21 countries. Four out of five people indicated they were prepared to change their lifestyle - even in the US and China, the world's two biggest emitters of carbon dioxide. Opinion was split over tax rises on oil and coal - 44% against, 50% in favour. Support would rise if the cash was used to boost efficiency and find new energy sources, the poll suggested.
