Greenhouse Gas Mitigation Benefits of Cycling Infrastructure: Insights from Existing Research

Overview

Cycling is widely recognized as a sustainable urban mobility solution, and many municipalities focus on cycling infrastructure expansion to promote improved environmental sustainability. This study explores findings from the current literature that explore the GHG emissions-related benefits (or costs) of cycling infrastructure.

Study Purpose

The purpose of this study is to explore the less explored environmental benefits including GHG mitigation benefits as the current literature on cycling has predominantly focused on safety and health benefits.

Methods

• Literature review using five major scientific databases, following the PRISMA guidelines.

Key Findings

• Cycling offers significant operational benefits by reducing GHG emissions, especially in the context of large-scale expansions of cycling infrastructure.
• Existing research indicates that even when embodied emissions are considered, bicycles are a more sustainable mode of transportation compared to cars or even public transit.
• Emissions associated with installation and maintenance of cycling infrastructure may sometimes negate the GHG benefits associated with additional cycling.
