Summary

In 2012, the Climate and Clean Air Coalition (CCAC) launched the Heavy-Duty Vehicles and Engines Initiative to "virtually eliminate fine particle and black carbon emissions from new and existing heavy-duty diesel vehicles and engines through the introduction of low-sulfur fuels and vehicle emission standards." Since 2012 there has been a steady progression to cleaner fuels and vehicles in many markets in Asia, Latin America, Africa and Eastern Europe (Figure 1). However, improvements in both fuel refining and importing markets need to be sustained through the next decade to realise the full air quality and climate change mitigation potential of cleaner fuels and vehicles.
