Corporations making up the UK's benchmark FTSE stock index reported the highest levels of greenhouse gas emissions this year, according to a report from the Climate Disclosure Project.

This year's FTSE 350 Report shows UK companies are disclosing the highest ever levels of greenhouse gas emissions — at 390 million metric tons of CO2-equivalent, equating to 61% of total UK emissions. But only 35% of the FTSE 350 disclosed emissions reduction targets. Some environmental campaigners say this only highlights the unwillingness of major corporations to be open about their environmental credentials -- The Guardian.

These numbers account for only the companies that have voluntarily disclosed (about 35% of the FTSE 350).
