Environmentally sustainable transportation helps reduce environmental pollution and greenhouse gas emissions and minimize the use of non-renewable natural resources. It also maintains ecosystem integrity and improves the climate resilience of transportation services, modes and infrastructure. Mitigation in this sector involves a shift toward sustainable transportation based on using cleaner technologies and improving energy efficiency in public and private transportation. Public transportation, active mobility and sustainable urban planning also help reduce carbon emissions and improve air quality in cities. Adaptation requires investments in climate-resilient infrastructure and the inclusion of climate considerations in transportation planning and design. The diversification of energy sources in transportation is also encouraged to reduce vulnerability to fossil fuel supply disruptions caused by extreme weather events.
