The transportation sector has a significant impact on both the local and global environment. Transportation contributes approximately 25 percent of global greenhouse gas emissions, and has a significant impact on local air quality and equity. Fortunately, cities are constantly finding new and innovative ways to mitigate that impact. Founded by ICLEI in 2011, the EcoMobility Alliance is a network of ambitious local and regional governments, supported by experts and businesses, aiming to become ecomobility frontrunners by prioritizing people and the environment when it comes to transport planning. The EcoMobility Alliance offers a platform through which local and regional governments share the latest policy and technology developments in their cities and regions, with the goal of making effective reforms to their own transportation networks.
