RT null T1 Cleaning Up the Global On-Road Diesel Fleet: A Global Strategy to Introduce Low-sulfur Fuels and Cleaner Diesel Vehicles - As prepared by the Heavy - Duty Diesel Initiative of the Climate and Clean Air Coalition A1 United Nations Environment Programme, K1 fuel K1 motor vehicle emission K1 diesel fuel YR 2016 FD 2016-08 LK https://wedocs.unep.org/handle/20.500.11822/21552 UL https://wedocs.unep.org/handle/20.500.11822/21552 NO This document presents a strategy for how the world can transition to low-sulfur fuels and cleaner diesel vehicles within the next decade. It also outlines why this is imperative for both health and climate goals. Achieving this change will require a focus on countries that are fuel importers, those struggling to secure financing for refinery upgrades, and those that have yet to match already- available low-sulfur fuels with the vehicle emission standards that secure the full air quality and climate benefits of desulfurization.
