Decarbonizing Aviation: Enabling Technologies for a Net-Zero Future
Executive Summary Combustion of jet fuel is one of the most important mechanisms by which aviation contributes to climate change, accounting for an estimated 2%–3% of global carbon dioxide (CO2) emissions before considering additional warming effects from contrails. Those emissions could triple by 2050, potentially accounting for 25% of CO2…

Clean Hydrogen for Poland’s Decarbonisation
Poland faces significant challenges in transitioning to a decarbonised energy system, given its historical reliance on coal and the need to diversify away from fossil fuels. To ensure a sustainable, resilient, and just transition, the country must implement a comprehensive, sector-specific plan that will deploy a diverse portfolio of decarbonisation…

Accounting for soil organic carbon for section 40B eligibility is neither aligned with statute or technologically feasible
CORSIA and the current version of Department of Energy’s GREET model do not align on crediting changes in organic carbon in cultivated soils.
-
GREET underestimates indirect land use change, undermining the climate benefits of section 40B
GREET underestimates indirect land use change compared to the Carbon Offsetting and Reduction Scheme for International Aviation.

Alternative incrementality compliance pathways
A 5% exemption to incrementality is too broad and will increase systemwide emissions, contrary to the text and intent of section 45V.
