2020s

Transportation technologies in society

2020 – The COVID-19 pandemic, partly due to lockdowns, temporarily drastically reduces the use of surface (including public) and air transport technologies. Cycling is an exception to this and increased during the pandemic, along with bike-sales.
2022 – A study for the first time attempts to assess and quantify complete societal costs of cars (i.e. car-use, etc.) by quantifying externalities.
2022 – A study estimates the air pollution impacts on climate change and the ozone layer from rocket launches and re-entry of reusable components and debris in 2019 and from a theoretical future space industry extrapolated from the "billionaire space race". It concludes that substantial effects from routine space tourism should "motivate regulation".
2023 – A study outlines challenges of aviation decarbonization by 2050 whose identified factors mainly are future demand, continuous efficiency improvements, new short-haul engines, higher SAF (biofuel) production (including measures that affect their competitiveness and deployment), CO₂ removal to compensate for non-CO₂ forcing, and related policy-options. With constant air transport demand and aircraft efficiency, decarbonizing aviation would require nearly five times the 2019 worldwide biofuel production, competing with other hard-to-decarbonize sectors and land-use (or food security).

Sustainable transport

2020 – First commercial flight of a hydrogen fuel cell plane.
2020 – Google Maps begins including bike shares in its widely used route planning functionality.
Early 2020s – Researchers investigate safe ways of public transport during the COVID-19 pandemic.
2022 – The first rail line entirely run by hydrogen-powered trains debuts in Germany. The state company owning the railway later switches to electric models since they are "cheaper to operate". Two other hydrogen trains have been reported as of 2023: Mireo Plus H by Siemens in Germany (under development) and an urban train by the Railway Rolling Stock Corporation in China.
2023 – The first test-runs of a superconducting maglev test line, called a hyperloop, are carried out in Datong, China (50 km/h of ~1,000 km/h). Hyperloop One conducted the world's first test carrying passengers in pods, reaching a speed of 172 km/h in Los Angeles in 2020, but reportedly abandoned the goal of transporting humans as of 2023.
2023 – A comeback of sleeping trains in Europe is reported as demand for more comfortable travel modes than overnight buses and sustainable transport rises. A new generation of such trains is released.

2021 – The pilot project of the "world's first automated, driverless train" is launched in the city of Hamburg, Germany. The conventional, standard-track, non-metro train technology could, according to reports, theoretically be implemented for rail transport worldwide and is reported to also be substantially more energy efficient.^{[contradictory]}
2021 – The world's first urban autonomous vessels, Roboats, are deployed in the canals of Amsterdam, Netherlands. The ships developed by three institutions could carry up to five people, collect waste, deliver goods, and provide "on-demand infrastructure".
