“[Passenger vehicle efficiency technology] costs continue to decrease, proving that previous estimates, including those made by the federal regulatory agencies, have been too conservative. . . . Including these latest efficiency developments, compliance costs for the adopted 2025 standards will be 34%–40% lower than projected in the latest U.S. midterm evaluation regulatory analysis.”

    ICAO's Carbon Offsetting and Reduction Scheme for International Aviation will probably not provide a meaningful framework to transition to alternative jet fuels.

  • B10: Os debates sobre o combustível de referência não devem atrasar a adoção de limites de emissão rigorosos para veículos pesados no Brasil

    O Brasil é o último dos grandes mercados automotivos sem padrões para emissões de veículos pesados equivalentes ao Euro VI para proteção à saúde pública. A implementação rápida do P-8 resolveria tal situação, e as agências regulatórias não deveriam deixar questões inconsequentes como o calendário para a especificação do diesel de referência e conteúdo de biodiesel atrasarem sua implementação.
