How litigation is challenging offsetting claims

The document analyzes the rising trend of greenwashing litigation and regulatory enforcement against companies using carbon credits to claim carbon neutrality. It highlights a divergence between the European Union, UK, and Australia—where courts and regulators are increasingly skeptical of offsetting—and the United States, where outdated guidelines and judicial reluctance have created a more fragmented enforcement landscape. The briefing concludes that companies face growing financial and reputational risks and should shift from compensation-based claims to genuine internal emissions reductions.

• European courts have established precedents rejecting carbon-neutrality claims based on offsetting due to the inability to verify long-term carbon storage. A Swedish court ruled against Arla Foods, finding it "unverifiable and inadmissible to claim that emissions would be compensated through carbon credits over a 100-year period," noting that permanence risks like fire or drought undermine such claims.
• German courts have specifically challenged nature-based offsetting and the efficacy of 'buffer pools' used to mitigate non-permanence risks. In 2025, a court ruled Apple's 'CO2 neutral' claim for the Apple Watch misleading because the underlying eucalyptus project in Paraguay could not guarantee mitigation until 2050, and it ruled that "buffer pools cannot ensure that stored emissions remain permanently bound."
• The aviation sector has faced significant legal setbacks regarding the logic of offsetting. The Amsterdam District Court ruled in 2024 that 15 of 19 KLM advertisements were misleading, concluding that there is "no direct correlation" between financial contributions to reforestation and a reduction in a flight's environmental impact.
• In Australia, private litigation and regulatory pressure have led to the decline of government-backed certification. A lawsuit by Parents for Climate led EnergyAustralia to settle and phase out its 'Go neutral' product, with the company admitting that "offsets do not prevent or undo the harms caused by burning fossil fuels." This contributed to the announced closure of the Climate Active programme by mid-June 2027.
• The United States' enforcement of greenwashing is hindered by the Federal Trade Commission's (FTC) Green Guides, which have not been "substantively revised since 2012." This regulatory lag has led US courts to shift the burden of proof to consumers, as seen in the Evian case where the court suggested consumers should seek information beyond the front label in the absence of a regulatory standard.
• The EU's Empowering Consumers for the Green Transition (ECGT) Directive, enforceable from 27 September 2026, introduces a blanket prohibition on product-level climate claims based solely on offsetting. While it bans these for goods and services, it does not prohibit company-level compensation claims, which remain a regulatory loophole.
