An ICCT policy update report highlights that Brazil’s PROCONVE P-8 emission standards represent a significant strengthening of regulations for on-road heavy-duty vehicles, bringing the country into alignment with Euro VI emission standards. Adopted by Brazil’s National Council for the Environment (CONAMA), the standards apply to new passenger and freight vehicles above 3,856 kg and entered into fo...

Regulations play a key role in reducing methane emissions from the fossil fuel sector, as they provide an instrument to drive desired behaviors and actions to achieve common levels of performance across operators. Regulations that can achieve deep cuts in methane emissions from oil and gas systems must be built on a foundation of strong and transparent compliance and emissions reporting and prescr...

Key messagesLow-carbon mobility is healthy and cost-effectiveTransitioning to low-carbon transport reduces greenhouse gas emissions and also significantly improves public health, for example, by encouraging active mobility and lowering air pollution levels. These improvements contribute to decreased health-care expenditures, with the potential to balance investment costs in the long run.Urgent nee...

Since the beginning of 21st century, global greenhouse gas (GHG) emissions had followed an increasing trend mainly due to the increase in emissions from China and the other emerging economies. As a result, the atmospheric concentrations of greenhouse gases substantially increased enhancing the natural greenhouse effect, which may negatively affect the life on the Earth.According to the latest data...

This guidance was developed to clarify how the on-road testing requirement can be met in states with mandatory enhanced vehicle emission inspection and maintenance (I/M) programs. On-road testing is a necessary element of an I/M program that is required by the Clean Air Act (CAA) to be operated at the enhanced performance level. On-road testing involves the collection of emissions data from a samp...

EPA has adopted emission standards for almost every kind of engine, including everything from lawn mowers to cruise ships. To show compliance with these emission standards, engine manufacturers must follow test procedures specified in the Code of Federal Regulations. This page provides links to the appropriate regulatory citations and includes published information related to the test procedures. ...

On December 20, 2022, EPA adopted a final rule, “Control of Air Pollution from New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards,” that sets stronger emissions standards to further reduce air pollution, including pollutants that create ozone and particulate matter, from heavy-duty vehicles and engines starting in model year 2027. The final program includes new, more stringent emissions s...
