This year, CNCA identified seven promising, next-generation practices to share with other cities. They are Game Changers: impactful actions that can accelerate and amplify decarbonization in cities. This is what CNCA cities are doing and what is happening on the ground at the leading edge of city decarbonization practice. They are changing the game. And they are the next essential steps that many cities should consider on the pathway to carbon neutrality. Below, we explore these seven transformations occurring across our CNCA cities. By targeting actions that have the highest potential for rapid, deep urban GHG emissions reductions in key emissions sectors (energy supply, buildings, transportation, waste and food), these Game Changers are driving transformative change in each of these strategy areas.
