When climate action is discussed publicly, the conversation often centers around national targets, international agreements, or global emissions trajectories. We hear about net-zero pledges, COP summits, and billion-dollar climate commitments. But much of the work that determines whether cities actually become more resilient, equitable, and sustainable happens far closer to home.
It happens inside municipal offices, infrastructure plans, public health systems, housing programs, transit policies, and local budgeting decisions.
To better understand how climate strategy becomes tangible at the community level, I spoke with Katelyn Macdonald, a sustainability professional based in Ontario, Canada. Through her work on climate adaptation, infrastructure resilience, policy implementation, and community engagement, Ms. Macdonald offered a perspective that often receives less public attention: cities are where climate goals either become operational reality or remain abstract ambitions.
Our conversation explored the challenges of implementation, the role of local governments in climate resilience, and why the future of climate action may depend less on isolated policies and more on systems that coordinate people, infrastructure, finance, and behavior simultaneously.
Path Into Climate Work
Like many professionals working in sustainability today, Ms. Macdonald’s career path was not linear.
Her undergraduate background was in global development, and her early professional experiences spanned multiple industries, including health technology, event management, and alumni engagement. Rather than beginning with a clearly defined climate career trajectory, she focused initially on building transferable skills while exploring work she found meaningful and engaging.
Over time, however, environmental systems and sustainability emerged as recurring areas of interest. During this period, she became particularly interested in concepts surrounding circular economy design and regenerative systems thinking, inspired in part by works such as Cradle to Cradle and Upcycle.
This interest eventually led her to pursue a master’s degree focused on environment and business, where her research examined municipal climate plans through the lens of behavioral change. That focus became foundational to her later work.
Many municipal climate strategies include ambitious goals, such as increasing public transit use, reducing vehicle emissions, or encouraging more sustainable consumption patterns. Yet, as she explained, plans often fail to specify what behavior change actually looks like operationally. If a city wants twenty percent more residents to take public transportation, how does that transition realistically occur? What interventions, incentives, infrastructure, or social conditions make that shift possible?
These questions pushed her toward the intersection of policy implementation and systems design, a space where climate strategy becomes less theoretical and more operational.
Climate Action Is Already Happening at the City Scale
One of the most important themes from our conversation was the extent to which climate work already exists within local government systems, even if it is not always publicly visible. At the municipal level, climate work spans both mitigation and adaptation.
Mitigation focuses on reducing greenhouse gas emissions through measures such as building retrofits, renewable energy adoption, public transit expansion, and emissions standards.
Adaptation focuses on preparing communities for the impacts of climate change that are already occurring, including flooding, extreme heat, infrastructure stress, and public health risks.
Ms. Macdonald emphasized that municipalities are uniquely positioned to address these risks because so much urban infrastructure falls directly under local responsibility. This includes roads, water systems, stormwater management, housing programs, public health services, and emergency response planning. In practice, this means climate resilience is deeply intertwined with everyday city operations.
For example, extreme heat adaptation is not simply an environmental issue. It becomes a public health issue, a housing issue, and an equity issue simultaneously.
Municipal health agencies may coordinate heat response systems, public cooling spaces, outreach programs for vulnerable populations, and educational campaigns around heat risk. Housing authorities may need to retrofit buildings to reduce indoor heat exposure. Emergency services may need updated response strategies during heat events. Infrastructure teams may need to redesign urban surfaces and stormwater systems to handle new climate realities.
Climate change, in this sense, stops being a standalone environmental problem and becomes embedded within nearly every operational system a city manages.
Infrastructure, Risk, and Climate Resilience
A particularly fascinating aspect of Ms. Macdonald’s work involves climate risk assessments for public infrastructure.
Cities manage billions of dollars in physical assets: roads, bridges, buildings, transit systems, water treatment facilities, electrical infrastructure, and more. Climate change introduces new risks to all of them.
Flooding can damage transportation corridors. Extreme heat can strain electrical systems. Severe weather events can disrupt essential services. Municipalities, therefore, must evaluate not only which climate risks exist, but which risks are most urgent and financially significant.
This process often involves integrating climate science with asset management systems. Infrastructure teams assess:
- Which assets are most vulnerable
- Which assets are most essential to public services
- What level of risk is tolerable
- Where adaptation investments will produce the greatest resilience benefits
This creates a more strategic approach to adaptation planning. Rather than reacting only after disasters occur, municipalities attempt to prioritize investments proactively.
Importantly, Ms. Macdonald noted that adaptation planning increasingly includes both traditional infrastructure and green infrastructure.
Why Implementation Is the Hardest Part
While climate strategies and policy documents are important, implementation remains one of the greatest challenges in municipal climate work.
Ms. Macdonald explained that government processes can sometimes become heavily strategy-focused. Municipalities may spend years developing plans, frameworks, and policies before projects reach actual implementation.
The challenge is not necessarily a lack of ambition, but the pace and structure of institutional systems. Large organizations require coordination across departments, approvals, budgets, procurement systems, and political priorities. This can make climate implementation slow, even when the urgency of the problem is clear.
To address this, she emphasized the importance of iterative approaches and adaptive project management. Rather than waiting years for perfect strategies, municipalities increasingly need ways to implement smaller, actionable projects while continuing long-term planning simultaneously.
Interestingly, she drew comparisons to methodologies commonly used in the technology sector, particularly agile development frameworks. The idea is not to abandon strategy, but to balance planning with experimentation and rapid implementation. This reflects a broader realization across climate work: the speed of climate risk is beginning to outpace the speed of traditional governance systems.
Equity and Designing Climate Solutions With Communities
Another major theme in our conversation was community-centered climate design. Climate solutions often fail when they are designed for communities rather than with them.
Ms. Macdonald emphasized co-creation as a critical principle in municipal climate work. Programs become more effective when residents are involved early in the design process and when solutions reflect real community needs rather than assumptions made inside institutions.
This can involve questions such as:
- Is the program geographically accessible?
- Does it reflect the realities of the neighborhood?
- Are language barriers addressed?
- Does the community actually see the initiative as relevant?
A sustainability program that appears technically effective may still fail if residents do not perceive it as useful or accessible. This is especially important because climate impacts themselves are not distributed equally. Heat exposure, flooding vulnerability, transit access, housing quality, and infrastructure resilience often vary significantly between neighborhoods.
Equity, therefore, becomes not only a moral consideration but also a practical requirement for effective climate adaptation.
Climate Finance at the Municipal Level
Climate action also depends heavily on funding structures.
Municipal governments often rely on multiple financing mechanisms to support climate initiatives, including operational budgets, capital project funding, federal grants, infrastructure adaptation funds, specialized climate programs, green bonds, and revolving sustainability funds.
Federal funding plays a particularly important role in enabling large-scale climate projects. Ms. Macdonald described examples such as urban tree planting initiatives funded through Canadian federal programs. At the same time, municipalities are increasingly exploring more innovative financing approaches.
One emerging area where finance and accountability overlap involves climate budgeting and carbon budgeting systems. Rather than simply measuring emissions, these frameworks attempt to integrate climate considerations directly into budgeting and investment decisions.
This shifts climate work from being a separate environmental initiative to becoming part of core financial and operational planning.
Lessons for Students Interested in Climate Work
Toward the end of our conversation, I asked Ms. Macdonald what advice she would give students interested in climate, sustainability, or policy careers. Her answer centered less on mastering a specific technical skill and more on curiosity, exploration, and exposure.
Climate and sustainability work spans an enormous range of disciplines: data science, GIS and geospatial analysis, engineering, urban planning, infrastructure, public health, policy, behavioral science, finance, product design, communications, and more.
Many students, she noted, simply are not exposed to the breadth of careers that exist within the climate field. The most important step, therefore, is often talking to people, exploring projects, and learning directly from practitioners working in different areas.
This idea strongly resonated with me because it reflects exactly what I’ve experienced through My Air Aware. Every conversation reveals another layer of how interdisciplinary climate work has become. There is no single “climate career.”
Instead, climate work increasingly consists of interconnected systems of people solving problems from entirely different angles, all contributing toward the same broader goal of building a more resilient and sustainable future.
