Energy Efficiency: Transport

The global exchange for energy efficiency policies, data and impacts

Transport is responsible for around 29% of global final energy demand, a share that has been rapidly increasing. By implementing cost-effective energy efficiency opportunities available today, transport energy use could remain flat between now and 2040, despite activity levels doubling.


The Efficient World Scenario identifies opportunities in several transport sub-sectors


The Efficient World Scenario identifies the potential for transport activity to double by 2040, with energy use remaining at today's levels. Between now and 2040, efficiency could improve by at least 2.5% per year on averge in most transport sub-sectors.

	2000-16	2017-40
Passenger light-duty vehicles	0.5	2.8
Road freight	0.1 	2.6
Aviation	3.6	3.2
International Shipping	2.1	2.8

Tracking Clean Energy Progress on transport: More efforts needed

The IEA’s newly-enhanced Tracking Clean Energy Progress provides a comprehensive and rigorous assessment of a full range of energy technologies and sectors that are critical in a global clean-energy transition.

Global transport emissions grew by only 0.6% in 2017 (compared to 1.7% annually over the past decade), as efficiency improvements, electrification and biofuels helped limit the growth in energy demand. To meet the SDS goals, direct transport emissions must peak around 2020 and then fall by more than 9% by 2030.
