Nissan Motor Co., Ltd. has scored a perfect “100A” in the CDP Global 500 Climate Change Report 2014. This is the second year in a row that it has been nominated as a CDP global leader.

The company said this accomplishment recognizes Nissan for its eco-friendly corporate policies and transparent information disclosure about its environmental performance.

Nissan added it was among a few top responders awarded a perfect score of “100” in the Climate Disclosure Leadership Index (CDLI) for its extensive information disclosure about its environmental performance and corporate governance practices. It received the highest “A” rating in performance in the Climate Performance Leadership Index (CPLI) for its demonstrated actions to reduce CO2 emissions in its vehicle manufacturing processes.

These achievements were announced in the CDP Global 500 Climate Change Report 2014, which analyzes companies’ environmental strategies and efforts to reduce greenhouse gas emissions based on the responses from the world’s largest 500 listed corporations, and identifies the best performers. The 14th annual CDP index lists companies from the FTSE Global Equity Index Series (Global 500) that demonstrate strategies designed to improve a company’s impact on the environment.
