Large listed companies will have to disclose their greenhouse gas emissions in special reports if Tory plans to combat climate change go ahead.

The proposals, part of the 'quality of life' commission set up by Conservative leader David Cameron, will also require pension funds to include green credentials as a criteria for investment.

The commission is headed by former environment minister John Gummer and Ecologist magazine editor Zac Goldsmith.

The policy will call for listed companies with a turnover of £22.8m or more to include their emissions as part of their financial reporting.

If implemented, the new rules will require a significant effort for FTSE 350 companies to comply. Last year, only a quarter of the FTSE 100 publicly disclosed emissions and only 10% of the FTSE 350 made the disclosures.
