In November 2022, the European Commission released its proposed Euro 7 regulation for light-and heavy-duty vehicles, which limits the level of pollutants detrimental to human health, such as nitrogen oxides (NOx) and particulate matter (PM).

On 14 February 2023, the European Parliament voted to ban the sale of new petrol and diesel CO2-emitting cars as of 2035, making headway in the EU’s “Fit for 55” package and the transition to climate neutrality by 2050.

The proposed Euro 7 standards, which are to be implemented in 2027, set lower emissions limits than the current regulation, Euro VI, while expanding the driving conditions that are evaluated. This study provides insight into the emissions performance of the latest generation of diesel buses in Europe.

This study estimates the costs and benefits of adopting Euro VI standards in diesel HDVs in South Africa under different timelines of fuel quality and emission standard advancements. Based on the results, also make policy recommendations that would reduce HDV emissions and improve air quality and public health in South Africa.

In April of 2020, the Indian government introduced its Bharat Stage VI (BS VI) emissions standards for all new sales of automobiles, which replaced the Bharat Stage IV (BS IV) norms.

This paper reviews recent developments in the European passenger car market and assesses the implications for the proposed post-2021 CO2 emissions targets.

Market analyses by vehicle segment, weight category, manufacturer, and engine size are needed to optimize vehicle emission standards and testing requirements. In India, these are largely adopted from Euro standards to fit the Indian landscape, and that was the case with the Bharat Stage (BS) VI regulations that took effect April 1, 2020.

On-road diesel vehicles are the leading contributor to air pollution and associated disease burdens. Besides the impact on air quality and public health, black carbon from diesel engine exhaust produces significant near-term climate warming.

In December 2020, the Ministry of Ecology and Environment (MEE) of China updated the China IV emission standards for non-road mobile machinery.

This study analyzes the real-world emissions of seven Euro VI-D trucks and evaluates the avenues for extending the in-use PEMS test provisions to better capture a wider range of frequently occurring conditions in real operation. The analysis finds that urban operation is responsible for 50% to 90% of total NOx emissions from the trucks tested.
