Mobile air conditioning (MAC) systems are a significant source of greenhouse gas (GHG) emissions from vehicles. This study, conducted by the ICCT in partnership with the Institute for Governance & Sustainable Development (IGSD), examines the GHG benefits and costs of switching to improved refrigerants and more efficient AC systems.

In December 2019, the China Ministry of Transport released an upgraded action plan for establishing a national domestic emission control area (DECA). This action plan marks China’s ambition to keep pace with world-class environmental regulations.

Brazil’s new PROCONVE P-8 standards will apply to all new on-road passenger and freight vehicles equipped with compression-ignition or spark-ignition engines and weighing at least 3,856 kg. These vehicle categories currently account for an outsized contribution to on-road vehicle emissions in Brazil.

Some 385,000 people worldwide died prematurely in 2015 from air pollution caused by vehicle exhaust emissions finds this study published by International Council on Clean Transportation (ICCT) which singled out diesel engines as the main culprit. China, the EU, the United States, and India accounted for 70% of global transportation-attributable PM2.5 and ozone deaths but just under half of the global population.

This briefing assesses and summarizes electric vehicle adoption among five of the world’s largest ride-hailing companies. It discusses company-specific electric vehicle adoption, plans for future growth, and catalogues the unique actions that companies are exploring to promote electric ride-hailing on their platforms.

As Arctic shipping increases, pressure is mounting to protect the environment from fuels that are harmful when burned and spilled, including heavy fuel oil (HFO). Presently, the IMO is working to develop a ban on HFO in Arctic waters.

In January 2018, the city of São Paulo, Brazil, adopted Law 16.802, an amendment to its Climate Change Law that sets 10-year and 20-year targets for fleetwide reductions in tailpipe emissions of fossil carbon dioxide (CO2) and the air pollutants particulate matter (PM) and nitrogen oxides (NOx).

This paper estimates the environmental impacts of reintroducing commercial supersonic transport (SST) aircraft into the global aviation fleet. Model the landing and takeoff (LTO) noise, sonic boom, and carbon dioxide (CO2) emissions from a new, unconstrained SST network of 2,000 in 2035.

This report quantifies the gap in charging infrastructure to power more than 3 million expected electric vehicles by 2025. Based on the expected growth across the 100 most populous U.S. metropolitan areas, estimate the amount of charging of various types that will be needed to power these vehicles.

Aviation is widely seen as the transport sector that is most difficult to decarbonize. One option to dramatically reduce emissions within the aviation sector is through the use of low-carbon alternative fuels.
