Current and future trends in electrification of road and air transportation

Transportation accounts for about 20% of the global greenhouse gas emissions, which is a major source of greenhouse gases. Road transportation accounts for three quarters of this share, while aviation and maritime transportation each account for 11% (see Figure 1). For improving the air quality and thus to achieve long term environmental sustainability, transportation electrification is an important area with the electricity used being generated from renewable energy sources. In 2022, there were 26 million electric cars on globally on the roads. Half of all electric vehicles (EVs) on the road were in China, according to the International Energy Agency's latest analysis of EV trends. In order to achieve net zero emissions from road vehicles by 2050, nearly 2 billion vehicles have to be either battery EVs or fuel cell based vehicles.
