The China VI standard is among the world’s most stringent HDV emission standards and combines best practices from both European and U.S. regulations. It will be a key pathway to clean up diesel emissions and is therefore a critical step toward winning the war against air pollution in China.

Diesel engines used to power non-road equipment and vehicles, such as agricultural tractors and construction equipment, are a significant source of air pollutant emissions.

This position brief makes specific recommendations regarding the adoption of Real Driving Emissions (RDE) testing in India.

South Africa’s new passenger vehicle fleet is the largest on the African continent and the 18th largest globally. South African manufacturers sold more than 412,000 new vehicles in 2015, and exported more than 333,000 units in that year.

This report presents the manufacturing costs of emission control technology used to meet recent U.S. and European emission standards for heavy-duty diesel engines and vehicles. The costs assessed include both the in-cylinder technologies to control engine-out emissions and the after treatment technologies that act on the exhaust stream.

Inspection and maintenance (I/M) programs are key to identifying high-emitting vehicles and mitigating their impact on air quality and climate. This paper assesses best practices for I/M programs targeting heavy-duty vehicles and makes recommendations on how to improve HDV I/M programs in the future.

In many regions of the world, older, high-emitting vehicles account for a small percentage of the overall vehicle fleet but a disproportionately large share of total emissions. It is estimated that these vehicles may be responsible for more than 50% of particulate matter (PM) and black carbon (BC) emissions by 2020 (Yan et al., 2011).

Investing in ultra-low-sulfur fuel (ULSF, fuels with less than 10 ppm sulfur content) and clean vehicle technologies in India will not come without costs. But the benefits of these investments, in terms of reduced healthcare costs and higher productivity, far outweigh the costs. This paper discusses these issues in detail.

This new working paper by ICCT identifies the most effective technologies for CO2, emissions and safety measures and maps the status of regulatory programs for 2- and 3-wheeler management in Asian countries.
