The inaugural Mumbai Climate Week 2026 concluded at the Jio World Convention Centre after three days of discussions, showcases and community engagement that brought together more than 2,000 delegates and over 500 speakers from over 30 countries. The programme featured more than 90 hub and focused sessions and over 20 spoke events and moved from conversation to intent to concrete pathways around three core themes: food systems, urban resilience and energy transition. Sessions on food systems explored resilient pathways, agroecology, market ecosystems and climate-smart agriculture alongside participatory community action. Urban resilience panels addressed blue-green infrastructure, heat impacts on outdoor work, healthy air zones and decarbonising the built environment. Energy transition discussions covered renewable deployment, green industrial growth, circular supply chains and clean mobility while stressing grid expansion and integration. The Governor of Maharashtra welcomed the initiative and reflected on traditional nature-revering practices and the need to counter modern materialism, while the state minister urged embedding environmental values into basic education so children grow up seeing nature as central to life. Conservation leaders and advisers emphasised nature-based solutions such as mangroves, wetlands and river corridors as living infrastructure and called for scientific restoration, spatial planning and financial innovation to scale action. The Government of Maharashtra unveiled a Climate Finance Access and Mobilisation Strategy dashboard, signed five memoranda of understanding with global partners and announced more than 1,000 urban climate projects across 44 AMRUT cities. The MCW Innovation Challenge showcased 34 finalists and eight winners alongside 96 exhibits and five installations that reflected Global South priorities. The Exhibition Arena brought together grassroots organisations, startups and corporates to create a live solutions marketplace and Project Mumbai launched a people’s climate dictionary to democratise climate language. Closing remarks urged that Mumbai serve as a laboratory for Public–Private–People partnerships and challenged participants to translate the week’s discussions into everyday choices ahead of 2027.
