Furthermore, on December 11, 2019, the European Commission published its communication on the «EU Green Deal», which aims to be the most ambitious package of measures that the European Commission has ever proposed, with the aim that Europe become the world’s first climate-neutral country by 2050.
Meanwhile, in March 2018, the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT) introduced the Real Driving Emissions (RDE) test for diesel vehicles. It will be applicable to new vehicle models from October 2022 and to existing vehicle models from October 2024.
The Ministry of the Environment (MOE) issued a Ministerial Ordinance on the regulation of the number of particles (PN) for diesel gasoline direct injection vehicles in August 2021.
Already the MLIT has announced the timing of the introduction of the PN regulation. Among direct injection diesel vehicles, it will be applicable to new models from October 2023 and to current models from September or October 2025.

In the European Union, the Green Deal is designed as a set of 10 profoundly transformative policies and more than 50 supporting legislative actions.
One of the policies (Sustainable and intelligent mobility) includes “Euro 7 as stricter standards of polluting emissions for vehicles with combustion engines”. The European Commission plans to propose Euro 7 in July 2022.
In parallel, China implemented the Step 6a emissions regulations in July 2020, based on the Euro 6 regulation. The Step 6a regulations were implemented in July 2020, and the Step 6b regulations will be implemented in July 2023.
Chinese President Xi Jinping proclaimed at the 75th session of the United Nations General Assembly held between September 2020 and September 2021 that China would address «reducing greenhouse gas emissions.»
