Big Oil’s Climate Ads Have Propped Up Fake Promises for 25 Years: Report

"First-of-its-kind analysis of hundreds of climate-related advertisements from BP, Chevron, ExxonMobil and Shell suggests that oil companies are continuing to mislead the public on climate."

"Four of the world’s biggest oil and gas companies have spent the last 25 years deceptively portraying themselves as leaders in addressing climate change while simultaneously expanding fossil fuel production and failing to meaningfully rein in their planet-heating emissions, according to a report released Thursday that examined over 300 of the companies’ climate-related advertisements from 2000 to 2025. 

These ads collectively serve to mask the harmful impacts of the companies’ operations and to perpetuate a false narrative that the oil industry is an essential partner in the fight against climate change, the Center for Climate Integrity found. 

CCI, a Washington, D.C.-based advocacy organization supporting efforts to hold fossil fuel companies accountable for climate harms, said its analysis is the first of its kind scrutinizing hundreds of climate-relevant ads from BP, Chevron, ExxonMobil and Shell across the first quarter of the 21st century. 

It was around the turn of the century, when outright denial of the reality of climate change had become untenable, that the fossil fuel industry pivoted in its messaging and advertising strategy toward promoting false promises and solutions for tackling the problem, CCI says in “Big Oil’s Deceptive Climate Ads.”"
