The clean energy claims of BP, Chevron, ExxonMobil and ShellA mismatch between discourse, actions and investments

BP, Shell, Chevron, and ExxonMobil have all described themselves, in their own words, as companies transforming toward clean energy. That claim is worth taking seriously and worth testing. Mei Li, Gregory Trencher, and Jusen Asuka did exactly that. They examined twelve years of annual reports, financial filings, and investment data, and what they found was a clear and measurable gap: the words went one direction, while the money went another. To understand why that gap matters, start with the scale of what these companies represent. Twenty fossil-fuel companies are responsible for thirty-five percent of all energy-related carbon dioxide and methane emissions worldwide since nineteen sixty-five. Among investor-owned firms, Chevron leads as the top emitter, followed closely by ExxonMobil, BP, and Shell. The products of those four companies alone account for more than ten percent of global carbon emissions since nineteen sixty-five. Any credible path to net-zero emissions by mid-century runs directly through their business models. The pressure is structural, not just moral. Electric vehicle adoption is accelerating, governments are moving to phase out internal combustion engines, divestment campaigns are gaining legal weight, and in twenty twenty, ExxonMobil was dropped from the Dow Jones Industrial Average after nearly a century — the same year Tesla's market value hit eight hundred billion dollars. BP has publicly suggested oil demand may have already peaked. These are not abstract signals; they are the market telling fossil-fuel producers that their core product faces declining demand. Against that backdrop, accusations of greenwashing have deep roots. The paper documents decades of corporate misinformation — ExxonMobil's multi-decade denial and disinformation campaigns, large-scale lobbying to weaken climate policy, and advertising strategies that repositioned fossil fuels, especially gas, as green. BP famously shifted public attention toward individual carbon footprints rather than corporate extraction. This history is why Li and colleagues set out to evaluate current claims with something more rigorous than press releases. Their method uses three parallel lenses, each revealing something the others cannot. First, discourse: they counted thirty-nine climate and clean-energy keywords in annual reports and normalized the counts against total report word length, producing a rate comparable across years and companies. Terms were grouped into four categories — climate change, transition, emissions, and clean energy. Second, business strategy: they scored twenty-five indicators split between pledges and disclosures on one side, and concrete actions on the other. Each indicator received a plus-one when evidence supported a transition, a minus-one when evidence contradicted it, and zero when nothing was found. Third, financial investments: they examined upstream capital expenditure, earnings from fossil fuels, production volumes, reserve estimates, downstream sales, and clean-energy spending — expressing changes relative to a two thousand nine baseline. The logic is simple and important: elevated keyword use can signal genuine attention or pure marketing, pledges can be vague, but capital allocation reveals actual priorities. The discourse findings are unambiguous. BP and Shell show sharp increases in climate and transition language across the study period. Shell's mentions of "low-carbon energy" rose almost tenfold, from fifty-nine to five hundred three. BP's climate change category mentions went from twenty-two to three hundred twenty-six, and transition-related terms from fifty to four hundred eighteen, between two thousand nine and two thousand twenty. The American majors lagged considerably. Chevron mentioned "climate" only forty-five times across the entire twelve-year period and omitted it from reports entirely from two thousand nine through two thousand eleven. ExxonMobil's usage remained low and erratic, complicated further by the fact that the company used brief summary reports in most years. The strategy scores follow a similar pattern. Pledges and disclosures — especially from BP and Shell — increased steadily, particularly after two thousand sixteen. BP introduced an internal carbon price of forty dollars per ton and pledged in two thousand nineteen to become a net-zero company by two thousand fifty. Shell announced carbon-intensity reduction targets of twenty percent by two thousand thirty, forty-five percent by two thousand thirty-five, and one hundred percent by two thousand fifty relative to a two thousand sixteen baseline, and was the first major to pledge reductions in scope three emissions — meaning the emissions from the products customers actually burn — in two thousand seventeen. Chevron and ExxonMobil had not announced net-zero goals by the end of the study period. But here is where the three-lens method earns its keep. Pledges are one thing. Actions are another. BP pledged to shift investment away from fossil fuels, then in two thousand nineteen increased its exploration acreage by fifty-eight thousand square kilometers and had multiple new extraction projects start in two thousand twenty. Shell stated its intention to refrain from new exploration after two thousand twenty-five, while simultaneously increasing undeveloped exploration acreage by roughly thirty-eight thousand square kilometers in two thousand twenty. Shell also pledged one to two billion dollars annually for renewables between two thousand eighteen and two thousand twenty — then disclosed actual two thousand twenty spending of nine hundred million dollars, less than half the lower bound of its own pledge. The financial picture is where the mismatch becomes sharpest. Upstream capital expenditure for fossil fuels dominated spending throughout the study period. For Chevron and ExxonMobil, upstream capital expenditure made up seventy to ninety percent of total expenditures from two thousand sixteen to two thousand twenty. Chevron's upstream share stayed near ninety percent in two thousand sixteen. Earnings followed the same pattern: upstream oil and gas profits typically accounted for seventy to eighty-five percent of integrated earnings across all four companies, with Chevron occasionally reaching ninety percent. From two thousand seventeen onward, Chevron, ExxonMobil, and Shell actually showed a growing share of earnings from upstream fossil-fuel operations. Production data reinforces the investment picture. No major consistently decreased total hydrocarbon production over the twelve years. ExxonMobil was the only company with a consistent production decline, falling from a two thousand eleven peak of four million five hundred six thousand barrels of oil equivalent per day to three million seven hundred sixty-one thousand in two thousand twenty. Shell, BP, and Chevron increased production volumes. Shell rose roughly twenty-five percent from two thousand fifteen to two thousand twenty, and Chevron grew gas production by about forty percent from two thousand sixteen to two thousand twenty. By two thousand nineteen, gas made up more than half of Chevron's total reserves. Clean-energy spending, by contrast, was small and opaque. Li and colleagues had to rely on third-party data because the companies themselves did not fully disclose annual figures — a transparency failure that is itself part of the finding. Over the study period, BP spent more than two percent of its total capital expenditure on clean energy, mostly in biomass and wind. Shell spent about one point thirty-three percent, mostly biomass. Chevron and ExxonMobil came in at roughly zero point twenty-two and zero point twenty-three percent respectively — far below the industry-average range of zero point five to zero point eight percent reported by the International Energy Agency for two thousand fifteen to two thousand nineteen. BP's total global renewables capacity across the decade amounted to about two thousand megawatts. ExxonMobil generated no clean energy at all during the period. Those numbers need a moment to land. The companies describing themselves as transitioning to clean energy were directing, at most, about one to two cents of every capital dollar toward that transition — and the figure for the American majors is barely a rounding error. Meanwhile, production volumes grew, reserve estimates held or expanded, and upstream earnings remained the overwhelming source of profit. Li, Trencher, and Asuka are direct about what this combination of evidence means: no major is currently on the way to a clean energy transition. Their conclusion is that accusations of greenwashing remain well-founded — not as a rhetorical judgment, but as the logical result of comparing three data streams. Discourse rose. Pledges accumulated. Investment in clean energy stayed near zero relative to fossil-fuel spending. The misalignment across all three lenses is consistent and measurable. Resolving it requires more than better language in an annual report. It requires translating pledges into verifiable capital reallocation and publishing year-by-year clean-energy spending with clear definitions of what counts as renewable, low-carbon, or clean. That last point matters for policy as much as for corporate accountability. If governments and investors cannot verify what these companies mean when they say they are transitioning, they cannot price carbon risk accurately, enforce climate commitments, or design regulation that actually bites. Li and colleagues frame transparency not as a courtesy, but as a precondition for any meaningful oversight. The words and the money have to move in the same direction.
