International Council On Clean Transportation

Marine and aviation programs:marine: the icct's marine program works to support policies that address the air quality and climate impacts of shipping at international, regional, and national levels as well as at local ports. Icct research has informed the international maritime organization's (imo) marine environmental protection committee (mepc) work on policies to reduce air pollution and greenhouse gas (ghg) emissions from international shipping. Initiatives include the development of emission control areas (ecas), an energy efficiency design index (eedi) for new vessels, controls for black carbon emissions, and imo's comprehensive ghg reduction strategy. The custom emissions inventory tools icct researchers have developed from satellite automatic information systems (s-ais) operations data are fundamentally strengthening the evidence base available to national and local policymakers working to reduce air pollution in coastal areas. For example, the icct's landmark fumes study found real-world methane emissions from ships fueled by liquefied natural gas to be much higher than assumed by the industry and regulators. Our work will lead to stronger regulations to control marine pollution.aviation: carbon emissions from commercial aviation are on track to triple by 2050 amid surging demand for passenger travel and transportation of freight. The icct aims to ensure that environmental policy for the aviation sector is informed by high-quality, transparent analyses of aircraft and airline performance, as well as the impact of policies on equitable access to air travel. Icct researchers investigate the development of aircraft technology, the design of environmental standards and tools such as carbon pricing, and the use of sustainable aviation fuels. The icct participates in groups such as the international civil aviation organization (icao) to contribute research directly to government agencies and organizations. Icct research also supports efforts to estimate emissions of specific flights so that consumers can make informed choices and minimize the carbon footprint of their travel.

Passenger vehicles/electric vehicles:the light-duty vehicle (ldv) sector-which includes passenger cars, light trucks and vans, motorcycles, scooters, and other two- and three-wheeled vehicles-accounts for about a third of global oil demand and produce about half of all transportation-related greenhouse gas (ghg) emissions. Icct's passenger vehicles program analyzes and identifies the technologies and public policies that are most effective at eliminating carbon and other harmful emissions from ldvs. While efficiency standards have reduced emissions from conventional ldvs, other pollutants like sulfur oxides, nitrogen oxides, and particulates still pose significant health and climate risks. Icct research helps identify and analyze additional public policy actions that could strengthen standards and help ensure car manufacturers develop and deploy the latest technologies to fight climate change.electrification is central to the icct's passenger vehicle (pv) program. Icct research supports an accelerated transition to zero-emission vehicles (zevs) and a thriving electric vehicle (ev) market. Icct reports provide in-depth summaries and analyses of ev trends, including the latest battery technologies and the deployment of charging infrastructure; how regulations, tax incentives, and nonfiscal policies help drive the ev market; and comparisons of policy approaches from around the world to identify best practices. For example, the icct produced the global automaker rating to assess how the world's largest auto manufacturers are progressing in the transition to evs.

International partnerships program:the international partnerships program (ipp) was founded in 2022 to recognize the growing importance of international initiatives and organizations crucial to decarbonizing transportation. Ipp combines under one umbrella multiple collaborations where icct plays a leadership role. Key program partnerships include: the real urban emissions (true) initiative to provide cities with real-world emission data to support strategic decision-making; the international zev alliance, consisting of about two dozen national and subnational governments with collective goals to expand the global zev market; the zev transition council, an international forum bringing together government ministers in the largest global car markets; the accelerating to zero coalition, a platform launched at cop26 for signatories of the zev declaration, now numbering more than 225, to work toward all sales of new cars and vans being zero emission globally by 2040, and by no later than 2035 in leading markets; and others. The ipp allows the icct to leverage its expertise globally and to help regulators and policymakers worldwide implement the best and most effective tools to combat climate change.

Renewable fuels:the icct fuels team develops accurate and applicable life-cycle analysis techniques to identify fuels that offer the greatest carbon reductions, including for hard-to-electrify sectors such as aviation and transoceanic shipping. Icct researchers help policymakers identify policies to ensure that biofuel feedstocks come from sustainable sources and that financial incentives effectively reduce the carbon intensity of biofuels. Research also analyzes future costs and availability of green hydrogen and other low-carbon fuels.

Strategic planning and modeling:the icct's modeling center develops the tools to analyze the costs and benefits of different policy options and their impact on climate and public health goals. This work enables policymakers and regulators to put transportation and environmental policy on a sound foundation globally. The modeling center covers all major modes of transportation, including road transport, aviation, and maritime shipping. The icct's modeling team applies its research tools in partnership with other icct regional and program teams to tackle subjects that include vehicle fuel efficiency and greenhouse gas standards, vehicle air pollutant emissions standards, emission impacts of new oceangoing ships, demand response to carbon pricing in aviation, low sulfur and low carbon fuels, fiscal and nonfiscal incentives for electric vehicles, and policies that encourage shifts to cleaner modes of transport and reduce the need for travel.
