2024年8月23日 · This page answers questions about GHG emissions from passenger vehicles and how these emissions are measured and calculated.

2025年2月28日 · The final rule builds upon EPA’s standards for federal greenhouse gas emissions standards for passenger cars and light trucks for model years 2023 through 2026, established in 2021, and leverages advances in clean car technology to unlock benefits to Americans ranging from improving public health through reducing smog- and soot-forming ...

2025年1月16日 · The largest sources of transportation-related greenhouse gas emissions include passenger cars, medium- and heavy-duty trucks, and light-duty trucks, including sport utility vehicles, pickup trucks, and minivans. These sources account for over half of the emissions from the transportation sector.

The GHG standards for passenger cars and light-trucks are based on the same emissions-footprint approach as the earlier regulations. The standards represent a nearly 50% reduction in projected fleet-average GHG emissions relative to the MY 2026 standards and achieve an industry-wide light-duty fleet average of 85 g/mi of CO 2 in MY 2032.

Highway vehicles release about 1.5 billion metric tons of greenhouse gases (GHGs) into the atmosphere each year—mostly in the form of carbon dioxide (CO 2)—contributing to global climate change. Each gallon of gasoline you burn creates 20 pounds of GHG. That's roughly 5 to 9 tons of GHG each year for a typical vehicle. Learn more …

2025年3月13日 · The threshold for the 2024 LCA Award was set at 100 g CO₂-eq/km (compared to 120 g CO₂-eq/km set for its first awardees), meaning only those vehicles with a total life cycle GHG emissions at or below this level receive the recognition. Out of 18 tested EVs last year, only five met this strict criterion, representing 28% of the assessed models.

2020年10月6日 · Are cars, trucks, planes, or trains the dominant sources? This chart shows global transport emissions in 2018. The data is sourced from the International Energy Agency (IEA). Road travel accounts for three-quarters of transport emissions. Most of this comes from passenger vehicles — cars and buses — contributing 45.1%.

2025年3月12日 · The U.S. Environmental Protection Agency on Wednesday said it'll reconsider the greenhouse gas tailpipe emissions regulations instituted by the Biden administration that are a key provision behind ...

2025年3月12日 · The Trump administration has begun the process of rolling back greenhouse-gas emissions rules set by the Biden administration for automobiles and trucks, the Environmental Protection Agency announced Wednesday. The agency will reconsider the proposed emissions standards for light-, medium- and heavy-duty vehicles beginning in model-year 2027, according to the announcement.

2024年11月21日 · Climate Watch Historical Emissions data contains sector-level greenhouse gas (GHG) emissions, including emissions of the six major GHGs from most major sources and sinks. Non-CO₂ emissions are expressed in CO₂ equivalents using 100-year global warming potential values from the Intergovernmental Panel on Climate Change (IPCC) Fourth ...
