Advancing climate ambition: how city-scale actions can contribute to global climate goals

New and continued efforts are needed to strengthen and extend the ambition of current national pledges to reduce greenhouse gas (GHG) emissions and to close the gap between the current global emissions pathway and a trajectory consistent with a 2°C target. This paper argues that cities have an important role to play in deepening the ambition of global climate targets. Cities have unique and strong influence over several policy levers – from urban planning to public
transportation – that make them critical actors in reducing GHG emissions, avoiding further carbon lock-in, and decreasing the cost of future abatement.
