The Solutions Exist. So Why Aren’t They Everywhere?
If solutions exist, why aren’t they everywhere? Our analysis points to four critical accelerators — pillars that leading cities use to consistently turn ambition into delivery. Each pillar represents a set of capabilities, resources, and strategies that allow cities to move from planning to action at scale.
1. Robust Implementation Architecture
Success requires more than ambitious plans; it demands a dedicated architecture for delivery. Leading cities establish specialized delivery units that coordinate across departments and navigate political, technical, and operational complexity. Mid-level implementors, often career public servants, play a critical role in translating strategy into action, bridging policy goals with practical realities on the ground.
Pilot projects are key to this architecture. They allow cities to test ideas, de-risk innovations, and build political and institutional support before wider roll-out. Shielding climate initiatives from short-term political cycles ensures continuity, while embedding flexibility allows cities to adapt as new data or technologies emerge. Cities like Bogotá, with its cycling infrastructure pilots, have demonstrated how this approach can scale rapidly and effectively.
2. Innovative Financing and Funding Models
One of the biggest barriers to city-led climate action is access to reliable, flexible financing. Leading cities are moving beyond reliance on grants, strategically leveraging municipal balance sheets, and redirecting procurement budgets toward climate-positive investments. For example, Malmö invests approximately €1 billion annually through its procurement to advance low-carbon, circular, and socially beneficial projects.
Equally important is quantifying the wider benefits of climate action, such as job creation, health improvements, and avoided climate damages, to build compelling investment cases. By demonstrating tangible returns alongside emissions reductions, cities can attract private capital, blended finance, and social investment. This kind of strategic financial thinking is critical to scaling solutions that otherwise might remain pilots.
