Notes: 

For several years ExxonMobil, the world's largest publicly traded international oil and gas company, has supported a revenue-neutral carbon tax. It believes that "market-based efforts to reduce greenhouse gas emissions – like a revenue-neutral carbon tax – are more economically efficient policy options than regulations, mandates, or standards."

During the United Nations Climate change Conference (COP21) held in Paris in December 2015, ExxonMobil received media attention for a blog post hopeful for an agreement in Paris that "will be reached for meaningful action to address the risks surrounding climate change." 

Ironically, around that same time in December 2015, New York State’s attorney general, Eric Schneiderman, subpoenaed ExxonMobil's records about its research going back decades. He took this action after InsideClimate News broke the story on September 16, 2015 that Exxon's Own Research Confirmed Fossil Fuels' Role in Global Warming Decades Ago. 

According InsideClimate News, Exxon top executives were warned of possible global catastrophe from greenhouse effect from their own internal company scientist, James F. Black, in July 1977. Unfortunately, Exxon then led efforts to block solutions for decades afterwards.

2016 is now a good time for ExxonMobil to attone of its efforts to "amplify doubt about the state of climate science" since 1977.

It should show it fully supports the 2015 Paris climate agreement by urging U.S. Congress to pass Citizens' Climate Lobby's carbon fee and dividend proposal and efforts by other governments to pass revenue neutral carbon tax.
