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 SN Not Available 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.
