Accelerator For Clean Air Actions (ACAAS)
The program focuses on strengthening local capacities in data-driven air quality analysis, planning, solution development, stakeholder engagement and long-term policy reform.
India’s urban air quality crisis demands targeted, data-driven, and locally relevant solutions. The Accelerator for Clean Air Actions (ACAAS) is a technical assistance program designed to support cities in translating clean air action plans into on-ground results that improve public health and urban livability.
Launched in 2023, ACAAS is working with 10 Indian cities—Mumbai, Pune, Surat, Vadodara, Ahmedabad, Chennai, Gurugram, Indore, Agra, and Gorakhpur—to strengthen their institutional capacity and scale effective air quality interventions.
Why ACAAS?
While the National Clean Air Programme (NCAP) has mobilized 131 non-attainment cities to prepare clean air action plans, the next challenge lies in effective implementation. The program is helping cities to develop local capacities in data-based understanding, plan strengthening, preparation of solutions, engaging stakeholders to build consensus for solutions, project implementation, and long-term policy changes.

Under ACAAS, WRI India is supporting partner cities through targeted sectoral interventions — including the adoption of clean construction practices, elimination of open waste burning, transition of bakeries to cleaner fuels, deployment of effective road dust mitigation techniques, and implementation of Low Emission Zones (LEZs) to reduce vehicular pollution.

ACAAS focuses on four key areas:
- Support cities to transition from air quality action plans to impactful projects and scale-up
- Enable cities to understand and leverage data to create science-based projects
- Create a peer platform for exchanges of learnings and best practices
- Equip ten cities with a nucleus of 30 changemakers to create an ecosystem for clean air actions
