![]() The pathways for the different elements of the transport sector in this optimistic scenario are shown in the visualization. ![]() There it outlines its “Sustainable Development Scenario” for reaching net-zero CO2 emissions from global energy by 2070. This is reflected in the IEA’s Energy Technology Perspective report. As the world shifts towards lower-carbon electricity sources, the rise of electric vehicles offers a viable option to reduce emissions from passenger vehicles. 2 Combined, these factors would result in a large increase in transport emissions.īut major technological innovations can help offset this rise in demand. ![]() In its Energy Technology Perspectives report, the International Energy Agency (IEA) expects global transport (measured in passenger-kilometers) to double, car ownership rates to increase by 60%, and demand for passenger and freight aviation to triple by 2070. Transport demand is expected to grow across the world in the coming decades as the global population increases, incomes rise, and more people can afford cars, trains and flights. Other transport – which is mainly the movement of materials such as water, oil, and gas via pipelines – is responsible for 2.2%. Rail travel and freight emits very little – only 1% of transport emissions. International shipping contributes a similar amount, at 10.6%. It emits just under one billion tonnes of CO 2 each year – around 2.5% of total global emissions. Since the entire transport sector accounts for 21% of total emissions, and road transport accounts for three-quarters of transport emissions, road transport accounts for 15% of total CO 2 emissions.Īviation – while it often gets the most attention in discussions on action against climate change – accounts for only 11.6% of transport emissions. The other 29.4% comes from trucks carrying freight. Most of this comes from passenger vehicles – cars and buses – which contribute 45.1%. Road travel accounts for three-quarters of transport emissions. ![]() This data is sourced from the International Energy Agency (IEA). In the chart here we see global transport emissions in 2018. How do these emissions break down? Is it cars, trucks, planes or trains that dominate? Transport accounts for around one-fifth of global carbon dioxide (CO 2) emissions. ![]()
