Business in the Community's new corporate responsibility index shows that corporate standards are most advanced in the area of environmental policy, while responsible business practice in the workplace, community and marketplace lag behind.
A total of 122 businesses, including more than half of the FTSE-100, completed the 82-page audit to take part in the index that was launched this year.
The average score for green policy was 71 per cent compared with just 54 per cent for responsible practice in the marketplace.
Elizabeth Forbes, spokesperson at Business in the Community, said: "The results reflect the fact that some companies have been assessing their corporate responsibility for years, while others are new to it.
"Environment was one of the first areas to be brought to the attention of companies and tackled."
