Letter from the Minister of Climate relating to The Climate Change Act 2008 (International Aviation and International Shipping) Regulations 2026, 17 April

From: Environmental Audit Committee

Inquiry: Airport expansion and climate and nature targets

Summary

The Minister for Climate informs the Environmental Audit Committee that the Government has laid statutory instruments to formally include UK international aviation and shipping (IAIS) emissions in the Sixth Carbon Budget (2033–37) and all subsequent carbon budgets and the net zero target. A second instrument sets international credits usable toward the Fifth Carbon Budget at zero. The move aligns with long-standing government planning and independent Climate Change Committee advice.

Key findings

  • Government has laid statutory instruments to include IAIS emissions in the Sixth Carbon Budget (2033–37), all subsequent budgets, and the 2050 net zero target
  • A separate instrument sets the level of international credits the Government can use toward the Fifth Carbon Budget (2028–32) at zero
  • The change does not alter the UK's legislated climate targets, introduce sector-specific limits, or set new policy requirements for aviation or shipping
  • The Government describes this as alignment with its long-standing planning assumption and reflects advice from the independent Climate Change Committee
  • Parliamentary committees, including the Environmental Audit Committee, have consistently called for IAIS emissions to be formally included in future carbon budgets
