Regulation & International Instruments
Climate policy
The body of government action — international, national and subnational — aimed at mitigating greenhouse-gas emissions and adapting to climate impacts.
Expert review openNo editor-accepted expert review yetDefinition
The strategies, laws, regulations, instruments and institutions through which governments address climate change, spanning mitigation (reducing emissions), adaptation (building resilience), finance and international cooperation. Its instrument families include carbon pricing, standards and mandates, subsidies and public investment, information and disclosure requirements, and international commitments under the UNFCCC–Paris framework.

Overview
What it means
Climate policy has a distinctive architecture: a global regime (UNFCCC, Kyoto Protocol, Paris Agreement) setting goals and transparency rules; national implementation through Nationally Determined Contributions — updated every five years — and Long-Term Low Emission Development Strategies; and a dense instrument mix at domestic level, from emissions trading and carbon taxes to clean-energy standards, vehicle rules and building codes.
Evaluation frameworks (e. g. UNEP's Emissions Gap Report, climate-policy databases) track whether the assembled policies bend emissions toward Paris pathways — currently insufficient. Design debates centre on instrument choice (pricing vs regulation vs industrial policy), sequencing, distributional fairness (just transition) and policy credibility over decades-long horizons.
How it is used
Governments design and legislate climate packages; businesses and investors price policy risk and direction into strategy; analysts benchmark policies against modelled pathways; courts increasingly review climate policy adequacy.
Why it matters
Climate policy is where climate science becomes binding collective action — the aggregate of its ambition and credibility determines the world's emissions trajectory.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
