NDC strengthened to 50% by 2030

What happened

Updated Paris Agreement NDC to 50% below gross 2005 levels by 2030 (~41% on multi-year budget basis). Government indicated significant portion could be met via international mitigation alongside domestic cuts.

Why it matters

Raises international commitment; headline ambition matters for global 1.5°C effort.

Impact assessment

Stronger target but offshore mitigation reliance and gap vs 1.5°C-compatible pathways limit score.

Scale: Provisional budget ~571 Mt CO2e (2021-2030)

Limitations: Domestic carbon budgets under Zero Carbon Act remain separate and more binding.
