From: Transport Committee

Summary

The Minister for Climate notifies Parliament that the Government has laid statutory instruments to formally include UK international aviation and shipping emissions in carbon budgets from 2033 onwards, setting international credits for the 2028–32 period at zero. The move aligns with longstanding planning assumptions and Climate Change Committee advice, without changing overall climate targets or imposing new sector-specific requirements.

Key findings

  • Separate instrument sets international credits available for the Fifth Carbon Budget (2028–32) at zero
  • Change does not alter the level of UK's currently legislated climate targets or introduce new sector-specific limits
  • Government states this reflects consistent parliamentary committee calls and independent Climate Change Committee advice
  • Emissions will be accounted for as part of whole-economy approach to net zero between 2033 and 2050
