TJX's corporate responsibility information has been indexed against GRI's G4 Guidelines, its fourth generation guidelines that were launched in May 2013. The TJX index is intended to help readers more easily navigate our website to the topic of interest.
In 2016, we participated in the CDP Climate Change Information Request for the seventh consecutive year, and we again delivered strong results, receiving a score of A-.
In Europe, since 2006, we have been working with the Carbon Trust to develop a strong environmental program with a focus on greenhouse gas (GHG) emissions reduction. In 2015, we were reaccredited with the Carbon Trust Standard certification, a certificate that is awarded biennially. While historically our Carbon Trust Standard certification was issued for our U.K. operations, in 2013 and 2015, the certification recognized our efforts throughout our entire European operations. As of 2015, we had reduced our European GHG emissions footprint by 6.5% relative to sales since 2013.
In addition to the recognition of our efforts by CDP and Carbon Trust, in 2016, we were once again listed on the FTSE4Good Index. We have been selected for inclusion on the FTSE4Good Index every year since 2001. Created by the global index company FTSE Group, FTSE4Good is an equity index series that is designed to facilitate investment in companies that meet globally recognized corporate responsibility standards, including stringent environmental criteria.
