The world was recently stunned to see the highest ever recorded concentration of carbon dioxide in our planet’s atmosphere: 415 parts per million, and rising. This figure, the highest in the millions of years that humans have existed, is unthinkably ominous to most of us. Yet it was no surprise for the company responsible for emitting a good share of that CO2: Exxon’s own scientists predicted this grim milestone with eerie accuracy way back in 1982.

If Exxon knew back then, what is the company doing to tackle the growing greenhouse gas emissions that are already causing a climate and extinction crisis? ExxonMobil investors, and the public, deserve to know. The company’s response has been to bury its head in the sand and continue with business as usual. But that is not cutting it, and this week’s annual general meeting (AGM) is a major test, with the company facing a push by some of its investors such as New York state pension fund to oust the entire board.

After a decade of the American fracking industry burning through hundreds of billions of dollars more than it earned, this industry previously dominated by shale drilling specialists is entering a new phase. The oil majors — a group of multinational companies that typically have divisions throughout the oil supply chain — now are investing heavily in fracked oil and gas operations.

A new report by a British think tank estimates that since the 2015 Paris Agreement, the world’s five largest listed oil and gas companies spent more than $1 billion lobbying to prevent climate change regulations while also running public relations campaigns aimed at maintaining public support for climate action.

Combined, the companies spend roughly $200 million a year pushing to delay or alter climate and energy rules, particularly in the U.S. — while spending $195 million a year “on branding campaigns that suggest they support an ambitious climate agenda,” according to InfluenceMap, a UK-based non-profit that researches how corporations influence climate policy.

The conservative think tank Competitive Enterprise Institute has been busily pressing forward with its mission to promote climate denial, using high-profile tactics like full-page ads in major newspapers. But it is also working behind the scenes, filing records requests to dig for information from cities filing climate liability suits and academics studying the topic. 

As the science has grown definitive in tying global warming to the burning of fossil fuels, even oil companies have been forced to acknowledge the overwhelming scientific consensus and back away publicly from climate denial efforts. But CEI continues to double down on their mission to claim the science is not settled.

CEI made a splash this week by purchasing full-page ads in the Washington Post and Wall Street Journal taking issue with Meet the Press host Chuck Todd and NBC for refusing to give airtime to denialists during his Dec. 30 show about climate change.
