The report details a 50-year campaign by the natural gas industry to brand its product as "clean energy" and a "bridge fuel." It argues that this was a strategic fraud designed to protect residential markets from electrification and later to facilitate a massive expansion of infrastructure. The document highlights the role of industry-funded research, specifically the Gas Research Institute (GRI), and a flawed 1996 joint study with the EPA that underestimated methane emissions to legitimize gas as a climate solution. It further describes how the industry used voluntary programs like Natural Gas STAR to fend off mandatory regulations and co-opted environmental organizations to lend credibility to its claims.

The provided text consists of appendices to a report by the Center for Climate Integrity. Appendix A lists trade associations, research institutes, and PR firms—such as the American Gas Association (AGA), the Gas Research Institute (GRI), and J. Walter Thompson—that collaborated to promote natural gas. Appendix B outlines a timeline from 1968 to 1996, detailing how the industry was alerted to methane's climate impact as early as 1968, launched a "clean energy" marketing campaign in 1972, and later promoted gas as a "bridge fuel" in 1990 despite internal uncertainties regarding methane leakage rates. It specifically highlights a 1996 GRI/EPA study that reported a 1.4 percent methane emission rate, which the document claims was heavily influenced by the industry and lacked independent technical review by the EPA.

The document is a formal statement by a coalition of state attorneys general and local officials opposing federal legislation that would shield fossil fuel companies from state-level lawsuits regarding climate deception and consumer protection violations.

A February 2026 survey of 749 registered Hawai‘i voters reveals that 85% view rising homeowners insurance costs as a serious problem, with 79% of homeowners experiencing rate increases in the last 2-3 years. While voters attribute these increases to various factors, including insurance industry profits (31%) and climate change (19%), there is significant support for state intervention. Specifically, 82% favor greater regulations to limit policy cancellations, and 61% support legislation allowing the State of Hawai‘i to sue oil and gas companies to recover insurance-related costs stemming from extreme weather disasters worsened by climate change.

Connecticut is experiencing accelerating climate risks, including more frequent extreme precipitation, rising sea levels, and increasing temperatures. The report details specific historical damages, such as a $300 million storm in August 2024 and $21 million in agricultural losses in July 2023. It projects significant future costs, including $5.3 billion for seawalls by 2040 and a 400% increase in days over 90 in Connecticut by 2050. The document provides comprehensive lists of potential adaptation costs across infrastructure, public health, and individual expenses to mitigate these hazards.

The report provides an extensive archive of advertisements from ExxonMobil, BP, Shell, and Chevron, organized into appendices that highlight deceptive themes such as overstating greenhouse gas reductions, exaggerating renewable energy commitments, shifting responsibility to consumers, and promoting natural gas, carbon capture, hydrogen, and algae biofuels as viable climate solutions.

The report analyzes over 300 advertisements from four oil majors, arguing that they used 'paltering'—mixing truth with omissions—to mislead the public about emissions reductions, renewable energy investments, and the viability of technologies like carbon capture and algae biofuels.

The report provides a detailed appendix of advertising campaigns from four major oil companies—BP, Chevron, ExxonMobil, and Shell—from 2000 to 2025. It identifies the agencies and professionals involved and describes the strategic goals of these campaigns, which often focused on rebranding the companies as environmentally responsible, promoting natural gas as a 'bridge' fuel, and shifting focus toward individual carbon footprints and low-carbon technologies like algae biofuels and carbon capture.

The document examines how climate change is creating a home insurance crisis in the U.S., characterized by skyrocketing premiums and widespread policy non-renewals. It asserts that 'Big Oil' companies, who knew about the risks of fossil fuels as early as 1954, are responsible for these conditions. The report highlights specific state-level crises in Florida, California, and Hawaiʻi, and advocates for policy solutions—such as subrogation and legislative surcharges—to shift the financial burden from policyholders to the fossil fuel industry.

A letter from Oregon's congressional delegation requesting the repeal of Executive Order 14260, which they argue illegally undermines the sovereignty of states and localities to pursue tort cases against oil and gas companies for climate deception and pollution.

A group of state Attorneys General requests that the U.S. Department of Justice recommend legislation to shield energy companies from climate-related liability and restrict federal funding for states pursuing climate lawsuits. The authors argue that such "climate lawfare" undermines national security and economic prosperity by targeting traditional energy resources like oil, natural gas, and coal.

The brief analyzes rate hikes by State Farm in California, noting that an approved 17% increase will raise average premiums by $737 by 2025, and a requested further 11% increase could raise them by $1,015 by 2026 compared to 2023. It highlights extreme increases in high-risk zip codes, such as Calabasas, and argues that the fossil fuel industry is responsible for the climate-fueled disasters driving these costs.

The report characterizes "advanced recycling" as a rebranding of chemical recycling, asserting that the plastics industry uses the term to greenwash its image and avoid regulations on virgin plastic production. It argues that chemical recycling is not a new technology, is economically unviable, cannot effectively process mixed post-consumer waste, and has a higher environmental footprint than mechanical recycling. The document further claims that the industry uses deceptive "mass balance" accounting to create a false appearance of circularity while primarily producing fuels rather than new plastics.

A coalition of organizations calls on Democratic leadership to reject efforts by the Trump administration and the fossil fuel industry to secure blanket waivers of liability for climate-related damages and deception.

The report examines how a 21.8% rate hike for State Farm homeowners insurance in California, approved in March 2025 following devastating wildfires in Los Angeles, disproportionately affects policyholders in high-risk areas. It projects that the average State Farm policyholder in California will pay $841 more in 2025 than in 2023, with some communities seeing premiums more than double. The analysis highlights that 280,000 policyholders across 122 communities will face annual premium increases of $1,000 or more. The document argues that these escalating costs are a direct result of climate change and suggests that the financial burden should shift from policyholders to the oil and gas companies responsible for fossil fuel pollution.

The report details how climate change is increasing the frequency and severity of extreme weather in Oregon, leading to significant economic losses and infrastructure needs. Key risks include intense heatwaves, devastating wildfires, disrupted water supplies for agriculture, and coastal flooding. The document provides specific cost estimates for adaptations, such as school air conditioning and coastal protection, while outlining the broader systemic risks to public health, fisheries, and the state's $5.7 billion agricultural industry.

Climate change in Illinois is manifesting as increased precipitation, rising temperatures, and intensified summer droughts, leading to significant infrastructure damage and public health risks. Since the 20th century, average annual precipitation has risen by 12-15%, while extreme events have increased by 40%, causing frequent flooding and sewage overflows in cities like Chicago. Rising temperatures are most pronounced in winter, with a predicted average increase of up to 9°F by 2100, which threatens agricultural yields—potentially reducing corn yields by 23-34% by mid-century—and necessitates an estimated $6.1 billion for school air conditioning by 2025. Additionally, intensified summer droughts threaten crop yields and river navigation, notably impacting barge transportation on the Mississippi River, while increasing the risk of wildfires and health issues from Canadian wildfire smoke.

The report details how Los Angeles County is affected by severe storms, rising sea levels, temperature extremes, and extreme drought. It highlights that flood risk threatens 27% of buildings in the city of Los Angeles and that the county spent 64% of the last 23 years in drought. The document provides extensive lists of potential costs, including infrastructure projects like seawalls, energy efficiency retrofits, and water treatment updates, while noting that disadvantaged populations are disproportionately exposed to flood risks.
