What do three leading chemical, automobile, and software companies have in common? All three – Honda, BASF, and SAP – are looking to curb risks and take advantage of opportunities across their global supply chains. They’re doing so by measuring their greenhouse gas emissions—not just in their operations, but up and down their value chains.
Many other multinationals are heading in the same direction. The Carbon Disclosure Project’s (CDP) annual survey of the Global 500, released last month, reveals that seven in ten respondents measured some value chain emissions in 2011, up from about half in 2010. (Note this figure is based on WRI’s analysis of the 405 companies that submitted data to the CDP 2012 survey data.)
What’s driving the world’s biggest corporations down this path? In a nutshell: reputation, risk, and opportunity.
