Climate change is weakening the political, economic, social, and technological systems needed for effective health governance, forcing governments to divert resources toward emergency responses and creating vulnerabilities that commercial actors can exploit. Dan Hunt and Dr Britta Matthes highlight that this destabilisation enables corporate influence over health policy, particularly as climate driven economic insecurity affects GDP, employment, and supply chains. The paper reveals how some commercial actors take advantage of these conditions—for example through casualised labour or raising prices for essential medicines during crises—and notes that over 70% of post industrial CO₂ emissions originate from just 78 corporate and state entities. It also emphasises the longstanding denial and delay strategies used by fossil fuel, plastics, and agrichemical industries to obstruct climate policy.
