Transportation roadmap

Transportation roadmap

In 2030, the number of motor vehicles on the world’s roads will be roughly double what it was in 2010: about 2.8 billion cars, trucks, motorcycles, and other vehicles. CO2 emissions from commercial aircraft are on a pace to triple by 2050, as both passenger air travel and air freight surge worldwide. Maritime shipping is also an increasingly significant source of greenhouse gas  emissions and local air pollution: fine particulate emissions from shipping are linked to approximately 60,000 premature deaths worldwide annually, and marine CO2 emissions could rise to 17% of all anthropogenic emissions in 2050 if left unchecked. Without forceful policies to improve the energy efficiency of and minimize pollutant emissions in the transportation sector, the consequences of such explosive growth for local air quality and public health, and for the global climate, will be dire.

In 2030, the number of motor vehicles on the world’s roads will be roughly double what it was in 2010: about 2.8 billion cars, trucks, motorcycles, and other vehicles. CO2 emissions from commercial aircraft are on a pace to triple by 2050, as both passenger air travel and air freight surge worldwide. Maritime shipping is also an increasingly significant source of greenhouse gas  emissions and local air pollution: fine particulate emissions from shipping are linked to approximately 60,000 premature deaths worldwide annually, and marine CO2 emissions could rise to 17% of all anthropogenic emissions in 2050 if left unchecked. Without forceful policies to improve the energy efficiency of and minimize pollutant emissions in the transportation sector, the consequences of such explosive growth for local air quality and public health, and for the global climate, will be dire.

Well-vetted data and analysis are keys to putting transportation and environmental policy on a sound foundation globally. Policymakers need access to robust findings on the costs and benefits of different policy options, and on the impact of these options on progress globally and regionally toward climate and health goals. ICCT’s roadmap program develops tools and research to meet that need by identifying plausible near-term steps toward regional, national, and international climate and health targets, including vehicle fuel efficiency and greenhouse gas standards, vehicle air pollutant emissions standards, fleet renewal and other in-use vehicle programs, low-sulfur and low-carbon fuels, fiscal and non-fiscal incentives for electric-drive vehicles, and policies that encourage shifts to cleaner modes of transport and reduce the need for travel. The ICCT's roadmap model covers fuel lifecycle emissions of GHGs and local air pollutants from all major transport modes, fuel types, and vehicle technologies. The global model covers eleven of the largest vehicle markets and five aggregate regions.

Exposure to outdoor air pollution ranks among the top ten health risks worldwide. Motorized transport is a major contributor. Imposing stricter limits on exhaust emissions of fine particulate matter (PM2.5) from light- and heavy-duty on-road vehicles in urban areas could have enormous health benefits.

Delta should double down on CSeries, fuel savings

Bombardier's new aircraft is mired in trade disputes, and that's creating some uncertainty over Delta Air Lines' order for 75 CS100 planes. But if Delta keeps its eye on the fuel savings it will reap—and remembers that the clean-sheet design CSeries is going to easily meet the ICAO CO2 standard—it will buy those aircraft, and more.
