As urban areas grow, so does their carbon footprint. Cities account for 67ā€“72% of global greenhouse gas emissions, making them critical battlegrounds in the fight against climate change. A recent study involving over 150 experts in planning, architecture, sustainability, and construction has identified 16 actionable strategies that can transform our cities into climate-resilient hubs.

Hereā€™s how urban professionals and governments can shift from good intentions to systemic, impactful change.

1. Acknowledge the Influence of Built Environment Professionals

Many professionals in urban development feel powerless to drive climate action, assuming decisions lie with clients or developers. The first step is recognizing that every roleā€”from planner to architectā€”has agency. Empower professionals to question, challenge, and reshape conventional processes.

2. Integrate Climate Risk Assessment from Day One

Early-stage development should include thorough climate risk analysis. Identifying flood zones, heat islands, or drought-prone areas early helps steer projects toward more resilient outcomes. Embed climate intelligence into the earliest decisions.

3. Mandate Climate Action Through Legislation

Voluntary sustainability measures often fall short. Clear, enforceable policy is needed to ensure climate goals are met. From building codes to zoning laws, climate mitigation and adaptation must be legally binding.

4. Educate for Cross-Disciplinary Climate Literacy

Climate action canā€™t be siloed. Professionals across architecture, urban planning, engineering, and construction must understand each other's climate-related responsibilities. Investing in ongoing, interdisciplinary education fosters collaboration.

5. Prioritize Low-Carbon Materials and Products

Material selection at the design stage significantly impacts emissions. Opting for recycled, low-carbon, and durable materials reduces the environmental footprint. Encourage innovation in material science and procurement policies.

6. Reform Costing and Approval Processes

The approval stage often sidelines climate-friendly features due to cost pressures. Introduce incentives, regulations, or financial instruments that ensure sustainable elements survive the budget phase.

7. Legislate Return on Investment for Sustainability

Many developers are profit-driven, so sustainability measures must be tied to tangible returns or be required by law. Mechanisms such as green building certifications, carbon credits, or tax incentives can make climate-friendly choices more appealing.

8. Foster Innovation in Construction Practices

Construction phases must allow flexibility to experiment with sustainable techniquesā€”like modular design or reused materials. Currently, risk aversion and regulatory rigidity discourage such innovation.

9. Ban Harmful Material Substitutions

When sustainable designs are approved, they are sometimes compromised during construction with cheaper, high-emission alternatives. Introduce systems that audit and enforce adherence to approved, low-impact specifications.

10. Implement Post-Construction Performance Reviews

Once buildings are in use, few are monitored for climate performance. Establish feedback loops that track energy use, carbon impact, and maintenance behavior. Include building occupants in this process for accountability.

11. Involve End Users in Climate Maintenance

Post-occupancy behavior can determine whether buildings live up to their sustainability ratings. Educate and involve users in ongoing energy efficiency, waste reduction, and climate-smart operations.

12. Promote Building Reuse Over Demolition

Demolishing and rebuilding is resource-intensive and wasteful. Encourage adaptive reuse, retrofits, and restoration of existing buildings as the default optionā€”especially in carbon-intensive sectors.

13. Support Circular Construction Economies

A circular mindsetā€”reuse, recycle, reconfigureā€”should govern urban renewal. Develop supply chains and construction practices that prioritize resource loops rather than single-use models.

14. Create Company-Wide Sustainability Standards

Firms in the built environment sector should integrate climate goals into their internal decision-making, workflows, and business models. Make climate action part of the company cultureā€”not just the project checklist.

15. Redesign Curricula for Future Urban Professionals

Universities must teach climate skills as core competencies, not electives. Future architects, planners, and builders should graduate already fluent in mitigation, adaptation, and sustainable design principles.

16. Reform Government Policy to Mandate Action

Finally, governments at all levels must revise outdated policies to reflect todayā€™s climate realities. From local planning laws to national housing programs, the regulatory framework must enforce climate accountability at every turn.

Conclusion

Cities are where climate change is both most visible and most solvable. These 16 game-changing actions offer a clear path to decarbonize the built environment and create urban spaces that are safe, inclusive, and resilient.

Now is the time to move from intention to implementationā€”and for every city stakeholder to become a climate champion.

FAQs

Why are cities important in the fight against climate change?

Cities produce up to 72% of global greenhouse gas emissions due to dense construction, transportation, and energy use. Transforming urban development is critical for emission reduction.

Who are the key stakeholders in implementing urban climate action?

Urban planners, architects, engineers, developers, policymakers, and local governments all play vital roles. End-users and educational institutions also influence outcomes.

What is the most overlooked stage in climate-focused urban development?

Post-construction performance and building reuse are often neglected. These stages are crucial for long-term emissions reduction and sustainability.

How can governments support climate action in cities?

By mandating climate considerations in zoning laws, building codes, and housing programs, and by incentivizing innovation, circularity, and carbon accountability.
