How climate denial shapes US climate policy now

Climate denial has moved from the fringes into formal US policy under the second Trump administration. The Guardian's fossil fuel and climate reporter Dharna Noor examines how denialist rhetoric – despite overwhelming scientific consensus on anthropogenic climate change – now shapes environmental and climate policy at federal level.

This matters beyond symbolism. When denial infiltrates executive decision-making, it stalls emissions reduction timelines, weakens climate risk disclosure standards, and undercuts international climate commitments. Companies operating under clarity on climate regulation suddenly face policy whiplash. Investors relying on consistent climate governance frameworks lose predictability. The fossil fuel industry gains political cover to resist transition pressure.

The video explainer format signals what many sustainability professionals already know: the political feasibility of climate action is inseparable from climate science acceptance. A second Trump term prioritising deregulation and fossil fuel expansion creates cascading consequences for corporate net-zero targets, scope 3 emissions accounting, and climate risk materiality assessments. Organisations with science-backed climate commitments now operate in an environment where official US policy denies the premise those commitments rest on.

This is not opinion journalism hiding as analysis. It's documenting a measurable policy shift with material consequences for ESG frameworks, climate finance, and renewable energy investment. The question isn't whether climate change is real – that settled decades ago. The question is how organisations navigate governance and strategy when official US policy rejects scientific consensus.
