Transport accounts for nearly one-quarter of global energy-related CO2 emissions. To achieve the necessary deep cuts in greenhouse gas emissions by 2050, transport must play a significant role.
However, car ownership worldwide is set to triple to over two billion by 2050. Trucking activity will double and air travel could increase four-fold. Without strong global action, these trends will lead to a doubling of transport energy use, with an even higher growth rate in CO2 emissions as the planet shifts toward high-CO2 synthetic fuels.
The new report by the International Energy Agency (IEA), Transport, Energy and CO2: Moving Toward Sustainability, looks at ways to enable growth in mobility without accelerating climate change. It finds that by shifting more travel to the most efficient modes, improving vehicle fuel efficiency by up to 50% using cost-effective, incremental technologies and moving toward electricity, hydrogen, and advanced biofuels, we can reduce transport CO2 emissions far below current levels by 2050, at lower costs than many assume. If governments implement strong policies to achieve this scenario, dramatic reductions in CO2 emissions by 2050 can be achieved.
