Controlling the composition of vehicle fuel can reduce pollutant emissions from combustion and, more importantly, enable the use of advanced emission control technologies. Achieving best-practice vehicle emission performance therefore depends on having standards for fuels in place that complement standards for vehicular emissions. But fuel standards alone areinsufficient. A compliance program is i...

The window to limit global temperature increases to 1.5°C above pre‑industrial levels is about to close. Keeping it open requires large emission reductions in the short term, followed by even larger reductions in the mid‑and long‑term. Against this background, the Paris Agreement requires that all Parties to the United Nations Framework Convention on Climate Change (UNFCCC) formulate and implement...

In response to a severe air pollution problem, China has implemented a series of comprehensive vehicle emission control policies. Among them are the China 6 light-duty vehicle (LDV) and China VI heavy-duty vehicle (HDV) emission standards, which take effect on July 1, 2020 and July 1, 2021, respectively. The China 6/VI standards combine best practices from both European and U.S. regulations and ar...

This paper aims to demonstrate the governance of gasoline/diesel supply policies and fuel quality management policies in Asia (Indonesia, Malaysia and Vietnam). Authors highlight two aspects of fuel quantity and quality management by looking at 1) automobile fuel supply policy and refinery development, and 2) emission regulation and fuel quality monitoring systems (FQM). This research allows us to...

The final rule establishes the Tier 3 Motor Vehicle Emission and Fuel Standards program. The Tier 3 program is part of a comprehensive approach to reducing the impacts of motor vehicles on air quality and public health. The program considers the vehicle and its fuel as an integrated system, setting new vehicle emissions standards and a new gasoline sulfur standard beginning in 2017. The vehicle em...

This document (2021 update) sets out to guide countries wishing to develop national plans to implement Short-Lived Climate Pollutant (SLCP) strategies.This guidance outlines a tried and tested process for developing national planning, focusing on action to reduce SLCPs. It is designed to provide advice and help to countries that wish to identify actions to promote the implementation of mitigation ...

The Partnership for Clean Fuels and Vehicles (PCFV) has been working with developing and transitional countries to reduce vehicular air pollution through the promotion of cleaner fuels and vehicles. This regulatory toolkit is part of that ongoing campaign and is meant to introduce the need for a systems approach to vehicle emission reduction. A systems approach matches fuels and vehicle improvemen...

Including non-CO₂ pollutants and air quality measures in the upcoming round of Nationally Determined Contributions (NDC 3.0) offers a wide range of benefits to countries from improvements to the climate, human health, food security, energy security, economic development, and beyond.Optimizing these benefits requires understanding and capacity as well as effective coordination and engagement from e...

The Regional Climate Strategy, supported and led by ECOWAS, creates a coherent basis for long-term climate action (2030 and 2050 horizons). It aims to consolidate and make coherent an intervention framework for the fight against climate change in the ECOWAS zone, taking into account both the adaptation and mitigation dimensions of climate change in line with the Paris Agreement and the 2030 Agenda...

Several publications were released in recent years that have provided insights and better understanding of short-lived climate pollutant (SLCP) science, including on their emissions, inventories and impacts, as well as on the benefits of emissions mitigation. They have also provided stronger scientific basis for action on SLCPs.This Climate and Clean Air Coalition Scientific Advisory Panel 2018 An...
