Plug-in electric vehicles are promising and sales have started, but it will take time to reach very large volumes, and will likely require strong incentives over the coming decade to reach a fully competitive point. carbon fuel vehicles will be needed to continue to decarbonize LDVs and reduce oil use out to 2050 and beyond.
A new study from the Harvard Kennedy School’s Belfer Center for Science and International Affairs finds that reducing greenhouse gas emissions from transportation will be a much bigger challenge than many assume, and will require substantially higher fuel prices combined with more stringent regulations.

Encouraging the use of low-carbon alternatives is an essential part of meeting climatechange targets as well as improving local air quality and health. Global, economy-wide carbon pricing is assumed as climate policy in both scenarios after 2020 (100 US$ per tCO 2 held constant over time). —McCollum et al. McCollum et al.
EU climate policy aims to limit the global mean temperature increase from anthropogenic climatechange to below 2 °C. EU climate policy aims to limit the global mean temperature increase from anthropogenic climatechange to below 2 °C. The horizontal lines indicate 60% reduction from year-1990 levels.
The steady tightening of standards will first incentivize combustion efficiency and in parallel speed up the deployment of new low-carbon technologies and fuels, such as vehicles running on low-carbon electricity, hydrogen, compressed natural gas or sustainable biofuels. Credibility requires beginning to implement policies now—i.e.
By working out that the price of oil will fall when the EU’s regulations fully take effect, the study suggests that the European economic benefits of fuel efficiency have been underestimated, in general by up to 17%, according to T&E. The dangerous part is with the price of oil likely to drop, demand for fuel will go up.
Among the proposed changes were additional production lead time; a reduced compliance obligation (i.e., Among the proposed changes were additional production lead time; a reduced compliance obligation (i.e., Earlier post.). by about 1.9%. by about 1.9%. For MY 2026 and following, the reduced compliance obligation goes away.).
New propulsion systems requiring new fuels, such as plug-in electric vehicle systems and fuel cell systems, are beyond the scope of this technology roadmap and are treated in separate roadmaps.

There are many options available for reducing the fuel, energy, and GHG emissions impacts of LDVs. Achieving our overall goal—reducing fleet fuel and energy consumption and GHGs by three-quarters or more—will be extremely challenging. Includes vehicle weight reduction: at constant acceleration capability.
