Mumbai's net-zero plan now tags the municipal budget against its own action tracks. The department meant to deliver it had four of 41 posts filled in June 2025.

Mumbai's climate action plan, published in March 2022 by the municipal corporation with WRI India as knowledge partner and C40 Cities as technical partner, sets a net-zero target for 2050 — the knowledge partner calls it the first such target set by a South Asian city. It rests on a greenhouse gas inventory and on an assessment of flooding, heat, landslide, coastal and air-pollution risk, and is organised around six action tracks. Since June 2024 the city tags its own budget against those tracks in an annual climate budget report, the first Indian city to publish one. Delivery lags the paperwork: the new environment and climate change department had four of 41 sanctioned posts filled in June 2025, and the same corporation won court permission in December 2025 to fell around 45,000 mangroves for a 26.3 km road.

Live 📅 since 2022

📊 Impact

The first climate budget report, in June 2024, tagged 10,224.24 crore rupees to the plan's action tracks — about 32.18% of capital expenditure of 31,774.59 crore. By the third report, in June 2026, the tagged capital expenditure was 20,731.04 crore, 43% of spending, and nearly 87% of it sat in a single track: urban flooding and water resource management, at 18,080.01 crore. The updated greenhouse gas inventory for 2022-23 records 24.56 million tonnes of CO2 equivalent, 1.86 tonnes a head.

🎓 Lesson

Budget tagging shows what a city already spends; it does not show what the city changed. Nearly 87% of Mumbai's climate capital sits in flood-resilient infrastructure and sewage management — the drainage, sewerage and water-supply programme the corporation runs in any case. Making that legible as climate spending is worth something; it is not the same as new abatement, and the plan's own inventory puts 72% of the city's emissions in energy and buildings, which is not where the money is tagged. The delivery arm is thinner than the tag: the environment and climate change department, carved out of solid waste management and given its own posts in March 2024, had four of 41 filled in June 2025 and still had no permanent office, and an independent assessment quotes the judgement that the plan has largely remained on paper since the state government changed. In December 2025 the same corporation obtained leave to fell around 45,000 mangroves for a 26.3 km road, against a duty to plant more than 1.3 lakh in another district and report on them annually for ten years.

Claim 1 clm-c3058e135d54b087 quantitative

What the mapping says
Citizen Matters dates the launch to March 2022 and names WRI as knowledge partner; C40 Cities describes the plan's goal of a net-zero and climate-resilient Mumbai by 2050; WRI states it was the first city in South Asia with a target to achieve net-zero emissions.
Caveat
The South Asian first is the knowledge partner's own claim about work it supported, not an independent finding.
