Financing Climate-Smart Cities

As the threats of climate change grow more severe, cities around the world are seeking innovative ways to reduce emissions and build resiliency against future impacts. Many cities are embracing the “climate-smart city” model – integrating climate change mitigation and adaptation into urban planning and operations. However, transitioning to climate-smart infrastructure requires major upfront investments that strain city budgets. Creative financing solutions are essential to overcoming this barrier.

Public-Private Partnerships

Public-private partnerships (PPPs) allow governments to contract with private companies to design, build, and finance projects. With PPPs, the private entity provides capital to cover the initial costs in exchange for operating the infrastructure over an extended concession period. This transfers much of the financial risk from taxpayers onto private balance sheets. PPPs have been used extensively to build climate-smart infrastructure like public transit systems, district energy plants, and resilient power grids. By ensuring future revenue streams, PPPs can leverage private capital to accelerate the deployment of transformative climate projects cities would struggle to fund on their own.

Green Bonds

Issuing municipal green bonds is another method cities are using to raise low-cost financing for climate adaptation and emissions reduction programs. The “green” label signals to investors that the funds will specifically support environmentally-beneficial projects. This branding allows cities to expand their investor base to include sustainability-focused funds. It also enables cities to potentially borrow at lower interest rates. In 2020 alone, cities issued over $45 billion in green bonds to mitigate climate impacts. Streamlining and standardizing green bond reporting requirements could bolster investor confidence and drive further growth in this climate-aligned asset class.

Climate Funds & Subsidies

A myriad of global climate funds have formed over the past decade to help cities in developing countries leapfrog to sustainable infrastructure systems. These include multi-lateral funds like the Green Climate Fund and the Climate Investment Funds. Significant funding is also flowing from national governments – the United States’ Inflation Reduction Act and India’s Smart Cities Mission being just two examples. Grant funding and subsidies can catalyze climate-smart city transitions in lower-income regions that have more difficulty raising their own financing for large capital projects. Wealthy nations should make meeting their collective $100 billion per year climate finance commitment a top priority if equitable climate-smart city proliferation is the end goal.

Policy and Governance for Climate-Smart Cities

Urban policymakers hold the power to pave the way for transformative climate progress within their jurisdictions. To steer cities toward low-carbon, climate-resilient trajectories, leaders across municipal government must coordinate to dismantle barriers and actively facilitate sustainable development. Strategic policies, structured governance models, and public-private collaboration can drive the systems-level changes needed for cities to embrace the climate-smart model.

Amending Zoning and Building Codes

Outdated zoning and building codes often unintentionally obstruct climate-smart urban growth. Municipal governments should conduct full reviews of their codes and amend where necessary to enable climate-aligned projects. Changes could include relaxing zoning to allow higher density, mixed-use development, reducing parking minimums to discourage automobile dependency, approving distributed renewable installations, and requiring all new constructions meet stringent energy efficiency and electrification benchmarks. Policy signals must clearly direct real estate developers to deliver sustainable buildings and infrastructure.

Streamlining Procurement Processes

Municipal governments also steer climate action through their sizable procurement budgets. Cities should streamline and standardize procurement policies to incentivize purchases of energy efficient products and clean technologies. Preferential purchasing of low-carbon goods and services amplifies market demand, scales sustainable industries, and nurtures local green jobs.

Developing Institutional Capacity

Realizing bold city climate plans requires building bureaucracies specially equipped to execute strategy. To institutionalize climate governance, cities should either establish new chief climate officer positions or dedicate full departments to oversee mitigation and adaptation initiatives across municipal operations. Further integrating climate planning with economic development, infrastructure management, budgeting, and health and social services is also critical for managing complex interdependencies. Investing in dedicated staff and governance systems brings structure and accountability to city climate programs.

Enabling Public-Private Collaborations

The scale of urban climate challenges far exceeds the capacity of local governments alone. Public-private partnerships allow cities to leverage business resources and expertise while businesses earn brand value by demonstrating climate leadership. Policies should facilitate sharing costs, risks, and rewards between public agencies and private entities on projects like building microgrids, deploying electric vehicle fleets, creating resilience hubs, and much more. Cities not only need comprehensive climate plans – they need binding governance frameworks that mobilize, coordinate, and maximize contributions from all partners.

Community Engagement and Equity

Cities pursuing the climate-smart model must put historically excluded and vulnerable communities at the center of planning processes to ensure equitable outcomes. Top-down, technocratic approaches to urban sustainability often fail to meet the needs of marginalized groups and reinforce environmental injustice. Avoiding this requires deliberately creating policies, programs, and projects to empower and uplift communities that climate change disproportionately burdens.

Inclusive Community Engagement

Robust community engagement enables cities to craft climate solutions directly informed by what residents actually want and need. Cities should actively seek participation from low-income communities, communities of color, immigrants, disabled populations and other groups typically excluded from political and civic life when formulating mitigation and adaptation plans. Engagement initiatives like surveys, neighborhood meetings, participatory budgeting and design processes, and advisory committees allow these groups to vocalize priorities and concerns. Their invaluable lived experience shines light on climate vulnerabilities requiring urgent attention and pathways for building equitable resilience.

Co-Creating Community-Led Plans

Truly equitable climate action requires devolving decision-making power to community members themselves. Cities should provide historically marginalized communities organizational support and resources to autonomously develop bottom-up climate preparedness plans tailored to their circumstances. Uplifting community-generated strategies that draw on groups’ existing strengths and networks builds agency over the climate response and empowers community self-determination.

Funding Community-Serving Projects

Cities also need targeted mechanisms to route climate dollars directly into underserved neighborhoods. Municipal grant programs can fund community-led resilience hubs, distributed clean energy projects, green workforce training programs, cooling centers, emergency preparation and response systems, and more. Preferential community access to sustainability funding via set-asides or scoring criteria in Requests for Proposals additionally elevates community-serving climate projects.

Prioritizing justice, equity and truly inclusive engagement provides a blueprint for climate action responsive to communities’ self-identified needs, not presumed needs. When historically excluded voices direct the vision and participate as equal partners, the resulting urban climate transition can transcend technocratic notions of “smart cities” to foster climate justice and community wellbeing.
