In cities around the world, ambitious air quality action is possible when it reflects how people live, work, and move.

Community engagement makes this happen by bringing residents into the policies and programmes that affect their lives. It helps cities design and implement them more effectively and sustain action over time.

Through grassroots and city-driven community engagement, Breathe Cities is supporting cities around the world to put communities at the heart of air quality action.

This resource builds on these efforts, drawing together existing resources and experience. Through case studies from Bangkok to Bogotá, Sofia to Johannesburg, it shows how different forms of engagement are applied in practice, from anchoring policies in local realities, to building support for citywide action.

When done well, engagement results in policies and programmes that respond to people’s needs. It gives communities the data and information they need to make informed choices and shape action, builds trust and buy-in, improves how problems are understood, captures what can be missed by technical data, and connects clean air action to wider issues and opportunities that matter for sustained change.

While engagement must be tailored to each context, cities do not need to start from scratch. They can build on tested approaches that already work.

Highlights

Meaningful community engagement helps cities design and implement policies that respond to people's needs, strengthen trust between institutions and communities, and sustain clean air action over time.
When done well, engagement bridges the gap between technical evidence and lived experience, improving how problems are understood while connecting clean air action to wider issues that matter in people's daily lives.
Cities do not need to start from scratch. By drawing on tested approaches and working with communities throughout the policy process, they can build more effective, inclusive and lasting clean air action.

Four key lessons stand out for cities undertaking engagement:

To be meaningful, engagement must be accessible, relevant, transparent, and lasting.

Engagement should reach the people most affected, while being clear about its purpose and why it matters to people’s lives. It should also create channels for feedback, follow-up, and continued participation.

Innovation can be unlocked through engagement and vice versa.

Meaningful community engagement helps unlock local knowledge, challenge assumptions, uncover new solutions and, as a result, design better, more innovative policies. Equally, using innovative engagement formats, such as art, music, public space activation, community monitoring, and online town halls can help reach new audiences. These formats make air quality concerns more tangible and strengthen recognition of the issue, improving engagement and longer-term support for implementation.

Quality of engagement matters more than scale.

A small, well-designed process can improve policy and implementation and strengthen decision-making when it is inclusive, linked to real choices, and followed by action. What matters most is whether the right people are involved in ways that can meaningfully shape outcomes.

Engagement is stronger when it brings different stakeholders together.

Community organisations, intermediaries, researchers, academic institutions, youth groups, and other local actors can help cities build trust, reach vulnerable groups, strengthen implementation, and sustain engagement over time. These partnerships create the wider ecosystem needed to turn participation into practical and lasting clean air action.
