All people deserve access to safe transport and mobility options. The transition of the world’s energy systems to decarbonized travel modes must be accomplished equitably in a way that provides opportunity for everyone.

Access to safe public transport and mobility is a basic need and is recognized as such by the U.N.’s Sustainable Development Goal (SDG) 11.2. It’s essential for participation in economic, social and cultural activities. Vulnerable individuals — including women, children, residents of lower-income and communities of color, persons with disabilities and older persons — need special attention to ensure access.

Accessibility is important to the success of decarbonization and is a goal in and of itself. 

It is important that the transition of the world’s energy systems to decarbonized modes of travel is accomplished equitably and in a way that provides opportunity for everyone.

In many countries, transport systems have been built to favor automobiles and rapid personal travel. Often, planners have overlooked how these individualized transport investments benefit persons at every income level, especially poor, marginalized people. Research from cities in the U.S., Brazil, Kenya and Mexico shows high-income residents enjoy better access to jobs and other opportunities due to the location of housing and transit infrastructure. Countries and cities need to prioritize transport systems that provide equal access to opportunities.

Safety is just as important in a decarbonized world as it is in our current system. 

All road users — including cyclists and pedestrians — deserve access to safe mobility options. Although road fatalities have slowly declined in recent years, they are still a long way from zero. And the downward trend is not universal: in some countries, like the U.S., vehicles are becoming larger on average, and therefore more dangerous to pedestrians, cyclists and smaller vehicles.

Key enablers and barriers to change

Other shift Other shifts needed to transform the system

Reduce avoidable vehicle and air travel

The most cost-effective means of reducing transport emissions is to avoid the need for motorized travel, utilizing city planning to bring opportunities closer to residents and encouraging less carbon-intensive modes of movement, such as public transport, walking and cycling.

Shift to public, shared and non-motorized transport

Achieving a sustainable, low-carbon transport system demands a comprehensive approach: avoiding unnecessary trips, shifting travel to more sustainable modes, improving transport technology and increasing access to jobs and opportunities.

Transition to zero-carbon cars, trucks and buses

Global greenhouse gas emissions from passenger cars, trucks and buses made up almost three-quarters of total transport emissions in 2020, underscoring the importance of a rapid transition away from fossil-fuel-powered vehicles.

Transition to zero-carbon shipping and aviation

Although both shipping and aviation are seen as “hard-to-decarbonize,” both sectors have pathways to a greener future. Decarbonizing shipping and aviation will require a combination of technological solutions, such as zero-emission fuels and batteries, alongside operational and efficiency improvements.
