How much CO ₂ can be saved by walking, cycling and e-biking in towns and cities?

*

Cyclists had 84% lower CO ₂ emissions from all daily travel than non-cyclists.

*

Life cycle CO ₂ emissions decreased by 14% for each additional cycling trip.

*

The top 10% of participants were responsible for 59% of life cycle CO ₂ emissions.

*

Regular cycling was most strongly associated with reduced life cycle CO ₂ emissions for commuting and social trips.

Abstract

Active travel (walking or cycling for transport) is considered the most sustainable form of personal transport. Yet its net effects on mobility-related CO ₂ emissions are complex and under-researched. Here we collected travel activity data in seven European cities and derived life cycle CO ₂ emissions across modes and purposes. Daily mobility-related life cycle CO ₂ emissions were 3.2 kgCO ₂ per person, with car travel contributing 70% and cycling 1%. Cyclists had 84% lower life cycle CO ₂ emissions than non-cyclists. Life cycle CO ₂ emissions decreased by −14% per additional cycling trip and decreased by −62% for each avoided car trip. An average person who 'shifted travel modes' from car to bike decreased life cycle CO ₂ emissions by 3.2 kgCO ₂/day. Promoting active travel should be a cornerstone of strategies to meet net zero carbon targets, particularly in urban areas, while also improving public health and quality of urban life.

Travel behaviour has evolved in unexpected ways in urbanised areas in the early 21st century. This report examines how significant breaks with past trends happened - and why these shifts were not foreseen. The Covid-19 pandemic adds to uncertainty about future demand to travel. Forecast-led transport planning is not well equipped to handle uncertainty. The report presents new approaches which explicitly address uncertainty, are vision-led and enable the development of resilient plans. It also considers how governance and institutions can be adapted to support such a paradigm shift.
