Over 100 institutions, 400 speakers including Bill Gates, Hillary Clinton, Union Ministers, International governments, Sachin Tendulkar, Cosmonauts, among those in attendance. From 17–19 February 2026, Mumbai will host the inaugural Mumbai Climate Week (MCW)
Over three days, the city will become a Global South climate leadership stage, as heads of government, global and Indian business leaders, climate innovators, philanthropies, youth and community voices come together to move from climate dialogue to action.
MCW will do this through a central hub at the Jio World Convention Centre and a citywide network of campus, community and cultural events that showcase and scale real-world climate solutions.
The global conversation on climate is being led by award-winning NGO Project Mumbai and is supported by the Government of Maharashtra, the Environment and Climate Change Department, MMRDA and the Brihanmumbai Municipal Corporation (BMC). It positions Mumbai as a living testbed for climate solutions that can be scaled across India and other Global South cities.
Speaking about MCW, Maharashtra Chief Minister Devendra Fadnavis said, “Mumbai Climate Week showcases India’s resolve to lead with action on climate, from the city level to the global stage. As Mumbai hosts leaders from across India and the world, including governments, businesses, financiers, experts and young people, we are sending a clear message that Maharashtra is ready to work with all partners to build cleaner, safer and more resilient futures for our citizens and for the Global South.”
“Mumbai has always been a city of grit and imagination, and Mumbai Climate Week is where that spirit meets the climate crisis at scale. This is India’s first citizen-led climate movement at this level, where ministers, businesses and experts share the same space as students, frontline workers and neighbourhood volunteers, and where Mumbai can signal what climate leadership from the Global South really looks like,” said Shishir Joshi, CEO & Founder, Project Mumbai and MCW.
MCW will also see participation from leading voices in Indian cinema who have championed environmental causes, including actor and UN Environment/UN SDG advocate Dia Mirza and actor Bhumi Pednekar, known for her “Climate Warrior” initiative and work on sustainable lifestyles and the SDGs.
Across the three days, plenary sessions on sub-national climate action, future cities and climate finance will bring together Chief Ministers and senior leaders from Indian states, underscoring the role of states and cities in driving net-zero, climate-resilient growth.
MCW’s programme is structured around three core focus areas that sit at the heart of India’s climate and development agenda: food systems, energy transition and urban resilience. The food systems pillar is anchored by India Climate Collaborative (ICC), working with a coalition of leading organisations across agriculture, nutrition, markets and finance. The energy transition pillar is supported by partners such as Shakti Sustainable Energy Foundation, Eversource Capital and ISEG Foundation, alongside sectoral experts and ecosystem collaborators. The urban resilience stream is anchored by WRI India in partnership with the HT Parekh Foundation and India Climate Collaborative as thematic partners.
Innovation, youth leadership and citizen engagement
Innovation is a cornerstone of Mumbai Climate Week. The MCW Innovation Challenge, led by the National Stock Exchange of India (NSE) as Innovation Challenge Partner, will invite early-stage and growth-ready innovators from startups, civil society, academia and the wider climate ecosystem to present high-impact solutions across three themes. Marico Innovation Foundation, Social Alpha are supporting the Innovation challenge while Climate Collective Foundation has curated a “Climate Redesign Challenge” contest for innovators
Finalists will receive mentoring and visibility and will pitch live at the MCW hub to policymakers, funders, industry leaders, philanthropies and global climate networks. Children and young people will be at the heart of MCW through a dedicated partnership with UNICEF India and YuWaah, the official Youth Engagement Partner for Mumbai Climate Week 2026.
Together with Project Mumbai, they will lead youth engagement throughout January and February via a Campus Roadshow and the Youth Green Innovation Challenge for young changemakers aged 16–24. Youth-led innovations across food systems, urban resilience and energy transition will be showcased during MCW, connecting young people directly with experts, policymakers and funders.
A new kind of climate week for India and the Global South
Mumbai Climate Week offers a distinctly Indian and Global South–led model for climate action, rooted in citizen engagement and city-level implementation. It reflects India’s resolve to lead with action on climate, as highlighted by state and city leadership in positioning MCW as a maiden, global-level climate summit for February 2026. With its Public–Private–People partnership architecture and hub-and-spoke design, MCW aims to become an annual platform where leaders, communities and partners return each year to track progress, scale successful pilots and co-create the next generation of climate solutions from Mumbai for India and the Global South.
