Mumbai announced detailed plans to zero out carbon emissions by 2050, a target that puts it two decades ahead of India’s national goal and makes it the first city in South Asia to set such a timeline.
In the plan announced Sunday, India’s financial center, home to south Asia’s biggest corporations, stock bourses and the central bank, has proposed exhaustive changes to the way it manages energy, water, air, waste, green spaces and transport for its 19 million residents.
“We don’t have the luxury of time,” said Aaditya Thackeray, environment minister of Maharashtra. Without intervention, the effects of climate change could cost India $35 trillion over the next 50 years.
Six domains
Mumbai, the country’s richest city, is also home to tremendous poverty, with slums and fishing villages along the southern coast that date to British rule. By 2050, rising sea levels are expected to flood those parts of the city. In total, unabated climate change could cost the city $920 million.
Drawing on inputs from officials, citizens, researchers and companies, Mumbai’s plan lists changes across six domains. This includes investments in housing, electrifying public transport, more walkable roads, flood-resistant drainage and water conservation apart from adding open spaces, investing in clean water and sanitation, and rooftop solar capacities.

Reaching ‘net zero’ by leveraging finance
Connecting all climate change mitigation activities, which would require some form of financing, can serve as an effective tool in greening the economyMumbai may consider raising funds through green bonds announced by the central government, according to Saurabh Punamiya, government adviser. It will receive funding from Maharashtra, which also plans to raise funds for climate mitigation projects through the central government and global lenders, said Tanmay Takle, policy advisor to the state government. This access to investments, along with a $6 billion annual budget, give the city an advantage over peers to implement climate targets. “The policies are actually opening the doors for such investments to come in,” Thackeray said.
Climate justice
Mumbai’s plan could help India rethink current models of development that put economic growth ahead of environmental stewardship, said Nikhil Anand, who teaches anthropology at the University of Pennsylvania. If Mumbai is successful, it could turn India’s focus to other pressing issues, including access to clean water and services for the city’s significant homeless population.
“To pursue development that secures climate justice in the near future is a non-negotiable,” said Anand. “The Climate Action Plan needs to take care of stabilising those systems, if it wants to make a meaningful difference in the life of its citizens.”
Future plans
In the coming three decades the city aims to cut to zero its total greenhouse emission which, in 2019, stood at 23.42 million tons or 1.8 tons per capita. The largest investments will have to come into energy, which accounts for 72 per cent of total emissions, according to plan documents. Vehicle emissions and waste comprise the rest.
Mumbai’s short-term priorities include the purchase of 2,100 electric buses by 2023 at a cost of ₹130 billion ($1.7 billion). The city will also spend on projects like retrofitting low-income homes with electricity-efficient equipment.
Plans for some crucial aspects of Mumbai’s transition — switching its peak 3,400MW electricity consumption to renewable power sources for instance — remain unclear. Private conglomerates, including the Tata Group and Adani’s companies, which supply power to the city mostly from coal plants, have said they will make investments in order to meet their own net-zero transition goals.
Other south Asian cities including New Delhi, Bangalore, Chennai, Kolkata, Dhaka and Karachi are also preparing climate action plans. Indian cities are also bracing for an influx of some 870 million migrants seeking refuge from crop failures, water scarcity and storms caused by rising temperatures.
“There are policy changes today which will move forward with every government,” Thackeray said. “Across India, there is a certain sense of urgency everyone feels.”
