A joint letter from environmental NGOs argues that the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is environmentally weak and inconsistent with the Paris Agreement. The authors demand that the EU maintain the more ambitious EU ETS for aviation and refrain from committing to CORSIA's voluntary phases until the legal review of the ETS Directive is finished.

  • EU aviation emissions grew by 96% between 1990 and 2016, representing 3.6% of total EU emissions.
  • The authors contend that CORSIA is an environmentally weak mechanism that violates the Paris Agreement because it relies on international credits and lacks a target for outbound aviation emissions, which would constitute 'backsliding' if used as the sole measure for aviation emissions.
  • The EU ETS is presented as a more ambitious and effective system than CORSIA, having achieved 100% compliance from more than 500 carriers.
  • The NGOs argue that EU member states cannot legally respond to ICAO's Standards and Recommended Practices (SARPs) or decide on voluntary participation in CORSIA until the European Parliament and Council complete the review of the EU ETS and CORSIA provisions required by the 2017 ETS Directive revision.
