Car ownership is set to triple by 2050, trucking activity will double and air travel
could increase fourfold. This book examines how to enable mobility without accelerating
climate change. It finds that if we change the way we travel, adopt technologies
to improve vehicle efficiency and shift to low-CO2 fuels, we can move onto a different
pathway where transport CO2 emissions by 2050 are far below current levels, at costs
that are lower than many assume.
The report discusses the prospects for shifting more travel to the most efficient
modes and reducing travel growth rates, improving vehicle fuel efficiency by up to
50% using cost-effective, incremental technologies, and moving toward electricity,
hydrogen, and advanced biofuels to achieve a more secure and sustainable transport
future. If governments implement strong policies to achieve this scenario, transport
can play its role and dramatically reduce CO2 emissions by 2050.
