World Bank air pollution study for India's most polluted region — errata notice

A World Bank working paper on air pollution solutions for northern India's Indo-Gangetic Plains and Himalayan foothills has issued a corrections document. This appears to be a routine errata — likely addressing data errors, methodology issues, or citation corrections in the original analysis — but without access to the actual corrections, the significance of what changed is unclear.

Air pollution in India's Indo-Gangetic Plains is among the worst in the world and affects hundreds of millions of people, so World Bank analysis of solutions matters as evidence for policy. An errata notice itself doesn't tell us what the substantive error was — whether it was a minor footnote fix or something that changes the core findings about which interventions actually work. The real signal would be: what findings changed, whose recommended solutions are now weaker or stronger, and whether this shifts India's or the World Bank's policy recommendations on coal, transport, or industrial controls.
