Courts around the world are grappling with the issue of whether companies, particularly fossil fuel giants like Shell and TotalEnergies, have a legal obligation to reduce their Scope 3 emissions, which account for the majority of their climate impact. While progress has been made in recognizing corporate responsibility for emissions, challenges remain in setting specific reduction targets without clear sectoral standards. The fight for corporate liability through the courts is connected to the push for companies to disclose their climate-related financial risks, with global standards in various jurisdictions now requiring Scope 3 disclosures. Despite setbacks like the stripping of the Climate Risk Disclosure Rule's Scope 3 requirement, the trend is clear that major companies are increasingly being held accountable for their emissions, underscoring the urgent need for climate action.
