Carbon Footprint — Operations: How does Chevron score?

Chevron reports Scope 1 (54 Mt) and Scope 2 (4 Mt market-based) emissions for FY2024, verified by DNV to a reasonable level of assurance using ISO14064-3:2019. Data is GHG Protocol-aligned with upstream/downstream breakdowns. However, operational emissions increased 1.85% year-on-year in 2024, which prevents a higher score despite granular and verified disclosure.

Carbon Footprint — Supply Chain: How does Chevron score?

Chevron reports Scope 3 only for Category 11 (Use of Sold Products) at 616 Mt CO₂e in 2024, covering just 1 of 15 GHG Protocol categories. This is the dominant category but the lack of any upstream Scope 3 data (purchased goods, capital goods, transportation, etc.) is a major gap for a company of this scale and complexity. The 2023 equity-based Scope 3 figure was approximately 406 Mt under the throughput method. Limited supply chain engagement on emissions.

Emissions Trajectory: How does Chevron score?

Total emissions (Scope 1+2+3) increased 6.51% in 2024 vs 2023, reaching 671 Mt CO₂e. Operational Scope 1+2 emissions also increased 1.85%. All Chevron targets are intensity-based, not absolute, meaning total emissions can and do rise as production increases. Chevron's total emissions have been steadily rising historically, with only a COVID-related dip in 2020. Per SINK rules, this trajectory scores near the bottom and is capped at 4 due to intensity-only targets.

Energy Source: How does Chevron score?

Chevron is not an RE100 member and has no published percentage of operational electricity from renewable sources. A 10-acre solar array was installed at the Mason City, Iowa biorefinery providing ~40% of that single facility's power needs. Between 2010-2018, only 0.2% of long-term investments went to low-carbon energy. Chevron is an enormous energy consumer as a major refiner and oil/gas producer, with 638 trillion BTUs consumed in 2024. No company-wide renewable energy strategy for own operatio

Nature & Biodiversity Impact: How does Chevron score?

Chevron has no TNFD-aligned disclosure and no quantified nature footprint. The Ecuadorian Amazon contamination — 16 billion gallons of toxic wastewater — remains one of the worst environmental disasters in history and has never been remediated by Chevron. Operations involve drilling in ecologically sensitive regions globally. Fracking operations are linked to habitat disruption. Some minor biodiversity work (species cataloguing in Argentina) does not offset the scale of documented environmental

Resource Use & Waste: How does Chevron score?

Chevron reports some waste metrics and has diverted 95% of waste from landfill at lubricants blending/packaging plants in 2023-2024. It announced a $200M investment to expand advanced recycling capacity. The company reports hazardous waste data per regulatory definitions. However, Chevron's core business is extractive and linear — producing fossil fuels that are combusted. No meaningful circularity strategy for the core business exists. Some recycling of produced water in fracking operations (98

Water Impact: How does Chevron score?

Chevron monitors water consumption using the WRI Aqueduct tool and reports freshwater withdrawn and consumed in water-stressed areas. The El Segundo Refinery reduced freshwater withdrawals by ~113,000 cubic meters via a water reuse project in 2024. In the Permian Basin, 98% of fracking water was from recycled/brackish/reclaimed sources. However, freshwater use in water-stressed areas increased in 2023, and the company's fracking operations are inherently water-intensive. Historical contamination

Targets & Commitments: How does Chevron score?

All Chevron targets are intensity-based, not absolute. The 2050 net zero aspiration covers only upstream Scope 1 and 2 on an equity basis — not total company, not Scope 3. The PCI target is a >5% intensity reduction by 2028 from 2016 levels. Oil & gas is excluded from SBTi validation, and Chevron has no SBTi commitment. Intensity targets explicitly allow absolute emissions to rise with production growth. Chevron has used carbon offsets but at trivial scale relative to its 671 Mt total footprint.

Transparency & Accountability: How does Chevron score?

Chevron publishes annual Corporate Sustainability Highlights, TCFD-aligned Climate Change Resilience Reports, and detailed performance data. GHG emissions are DNV-verified. However, Scope 3 coverage is limited to 1 of 15 categories. The company's Climate Lobbying Report (2020) was assessed by InfluenceMap as not including a review of alignment. No executive compensation linked to absolute emissions reduction. Board oversight exists but the company consistently opposed shareholder climate resolut

Controversies & Red Flags: How does Chevron score?

Starting from 8, severe deductions apply. Ecuador: $9.5B court judgment for dumping 16 billion gallons of toxic waste in the Amazon (unresolved, unpaid) (-3). FTC greenwashing complaint filed by Earthworks/Greenpeace/Global Witness (-2). InfluenceMap ranks Chevron as the 1st or 2nd most obstructive company on climate policy globally with a D- score — automatic cap at 3 for lobbying against climate policy (-5). Member of API and US Chamber of Commerce, both actively opposing climate regulation (-

Critical concernPending Review-3 since last review

Chevron's emissions are rising in absolute terms while it hides behind intensity targets and incomplete Scope 3 reporting. The company faces a $9.5B unpaid judgment for Ecuador contamination, active FTC greenwashing complaints, and ranks among the world's most obstructive forces on climate policy. No credible net-zero pathway exists.
