InfluenceMap's scoring system observed a flurry of pro-climate policy activity immediately prior to and following COP21 in Paris. This so-called “Paris effect” means that over half the global 100 industrial companies are now advocating for emissions reductions in line with 2C. Furthermore, a third of these 100 leading industrial corporations are explicitly supporting strands of legislation that put a price on carbon. This comes as a result of a flurry of pre COP21 activity such as policy support as part of the We Mean Business campaign, the American Business Act on Climate Pledge, strong CEO messaging from the likes of Apple and Unilever and a letter signed by CEOs from the World Economic Forum with specific policy language in it. From the pro-climate companies, InfluenceMap has ascertained true leaders who support progressive climate policy in a proactive and determined manner. These include visionary company Unilever, electric utilities National Grid and Iberdrola and electric vehicle company Tesla, all of whom appear to be "all in" for 1.5C and a low-carbon future.
