What does Exxon believe in?

ExxonMobil says it believes “the risk of climate change is real,” and it is “committed to being part of the solution.” Plus, it also says it supports a federal carbon tax and the Paris climate agreement. Yet, why did it give over $750,000 to such groups as the American Petroleum Institute? Why did it spend another million dollars on congressional candidates who did not believe that climate change was here?
