Delhi can improve its PM2.5 concentrations, but it will take at least 10 to 15 years of systematic implementation of a series of interventions, spanning all the sectors, at regional scale. The necessary effort to reach 40 ug/m3 in 2040 is substantial, requiring changes like those seen during the COVID-19 lockdown restrictions, in all the anthropogenic sectors. In addition to the year-round sources...

The Surat Clean Air Action Plan (SCAP) was prepared by World Resources Institute India (WRI-India) in collaboration with Surat Municipal Corporation (SMC) and the Gujarat Pollution Control Board (GPCB), and supported by Bloomberg Philanthropies and Shakti Sustainable Energy Foundation (SSEF).The source apportionment study, prepared by TERI, identified air pollution sources in Surat, resulting in t...

The document is an in-depth report detailing a primary survey on open municipal solid waste burning in Vadodara, India, a city identified as having critical air pollution issues. This study utilized a transect walk method during the summer and winter of 2023 to collect granular data on the frequency, mass, and composition of burning incidents across socioeconomic status (SES) and industrial zones....

The Africa Roadmap on Transformative Action to End Open Burning of Waste identifies the key actions to address the systemic deficiencies in waste management and promote waste to resource conversion that could generate multiple social, economic and environmental benefits. In 2025, the African Ministerial Conference on Environment endorsed the Roadmap, calling on all African national governments and...

Air pollution is one of today’s greatest public health threats, driving respiratory illness, cardiovascular disease and millions of premature deaths worldwide. Yet in many countries, reliable local data to understand and address these risks is limited. Clearing the Air Together: Pathways for Integrating Citizen Science in Air Quality Management Initiatives highlights how citizen science can bridge...

The electrification of Brazil’s heavy-duty trucking sector represents a critical opportunity to reduce greenhouse gas (GHG) emissions, improve air quality, and enhance public health. While Brazil’s long-standing reliance on biofuels has leveraged domestic resources and infrastructure, this strategy is best viewed as a transitional measure that may not fully meet the country’s long-term climate and...

Mini-grids, an increasingly attractive complement to conventional rural electrification, provide electricity to communities that would have to wait years for the arrival of the main grid. Recent innovations have spurred private interest in mini-grids, but further development will require better regulatory frameworks. Properly structured, light-handed regulation can lower risks to mini-grid develop...

Some 418 million children worldwide receive at least one school meal per day. However, in developing countries, most school meals are prepared using rudimentary, polluting biomass stove-and-fuel combinations, with unknown costs to the health of students and personnel, school finances, and the local environment. Scant data on the scale of the problem has limited the sector’s visibility, resulting i...

Household electrification is thought to be an important part of a carbon-neutral future and could also have additional benefits to adopting households such as improved air quality. However, the effectiveness of specific electrification policies in reducing total emissions and boosting household livelihoods remains a crucial open question in both developed and developing countries.
