Spada, a UK public relations consultancy has released a report called Environmental Reporting: Trends in FTSE 100 Sustainability Reports. The report is based on a review of 79 corporate responsibility reports of FTSE 100 companies. Among other things, it finds that longer corporate responsibility reports increase the likelihood of winning sustainability awards, with every extra page in a CR report increasing the likelihood of a company to win an international environmental award by up 3 percent.
