On April 29, the Investor Responsibility Research Center Institute (IRRCI) and the Sustainable Investments Institute (SI2) released a joint report titled Integrated Financial and Sustainability Reporting in the United States which examined the sustainability reporting of the top American Standard and Poor’s 500 companies. The report found that 499 of the 500 companies reported at least some aspect of sustainability practices in either voluntary reports or Securities and Exchange Commission filings in 2012. However, only seven companies completed integrated reporting, combining sustainability reporting with financial reporting. 68 percent of the companies disclosed environmental management practices; 66 percent discussed the impact of climate change in their reports.
