This map shows states that have adopted or are planning to adopt California’s vehicle standards.
This map shows state laws and regulations that affect medium- and heavy-duty vehicles. The policies include tax incentives, fines, guidelines, and grants.
This map shows states that have laws and regulations that incentivize the use of plug-in electric passenger vehicles. Policies include mandates for states to acquire plug-in electric vehicles for state fleets, access to High Occupancy Vehicle lanes or designated parking for plug-in electric vehicles, and financial incentives to private owners of such vehicles.
The Fifth U.S. Climate Action Report presents a detailed outline of the actions the U.S. is taking to address climate change, contains updated projections on U.S. greenhouse gas emissions, and underscores the United States commitment to address climate change.
U.S. passenger vehicles are one of the largest contributors to global warming pollution, responsible for roughly a quarter of annual U.S. energy-related emissions of CO2.
Better transportation choices can have an enormous impact on climate change. With our membersâ€™ support, UCS spearheads research that finds new and better ways to reduce harmful vehicle emissions.
Biomass is a clean, renewable energy source that can help to significantly diversify transportation fuels in the United States. The Biomass Program is helping transform the nation’s renewable and abundant biomass resources into cost-competitive, high-performance biofuels, bioproducts, and biopower.

Gliding on a wave of electromagnetic force, a maglev train could travel at 300 miles per hour or faster. Designer-engineers describe the mechanics and future benefits of such superconductor trains.

The brochure promotes urban transportation policy to increase the use of renewable energy to 100%. Seen globally, transport is one of the main sources of greenhouse gas emissions. Yet fossil fuels are becoming scarce, will become increasingly expensive and will eventually stop being viable as transport fuels. Before this happens, climate change will have begun to have a serious impact on human lives. The authors believe that it is crucial to replace fossil fuels with renewable energy as soon as possible, especially in the transport sector.
Making urban transport independent of fossil fuel is a great challenge, but the authors cite growing evidence that it can be achieved.
The Intergovernmental Panel on Climate Change (IPCC) was jointly established by the World Meteorological Organization
(WMO) and the United Nations Environment Programme (UNEP) in 1988 to: (i) assess available information on the science, the impacts, and the economics of, and the options for
mitigating and/or adapting to, climate change and (ii) provide,
on request, scientific/technical/socio-economic advice to the
Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC). Since then the IPCC has produced a series of Assessment Reports, Special Reports, Technical Papers, methodologies, and other
products that have become standard works of reference, widely used by policymakers, scientists, and other experts. This Special Report was prepared following a request from
the International Civil Aviation Organization (ICAO) and the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer. The state of understanding of the relevant science of the atmosphere, aviation technology, and socio-economic issues associated with mitigation options is assessed and reported for both subsonic and supersonic fleets. The potential effects that aviation has had in the past and may have in the future on
both stratospheric ozone depletion and global climate change are covered; environmental impacts of aviation at the local scale, however, are not addressed. The report synthesizes the findings to identify and characterize options for mitigating future impacts.
