Official greenhouse gas figures hugely underestimate Britain's contribution to climate change, a report concludes. Christian Aid says adding in emissions from UK-funded operations in other countries would raise the UK's share of the global total from 2% to about 15%. British companies wanted globalisation, it says, and must take responsibility for the associated emissions. The charity is calling on the government to ensure that companies measure their emissions thoroughly..."Our research reveals a truly staggering quantity of unreported carbon dioxide is emitted around the world by the top 100 companies on the London Stock Exchange," said Christian Aid's senior climate change analyst, Andrew Pendleton...But Trucost found that only 16 of the FTSE 100 report emissions according to the internationally recognised Greenhouse Gas Protocol (GHGP). "Some of the largest companies are beginning to get it, and you have companies like Marks and Spencer and Tesco and BSkyB all beginning to seek leadership positions," said Trucost's head of corporate services Neil McIndoe.
