In order to address climate issues, the Brihanmumbai Municipal Corporation (BMC) is preparing a Mumbai Climate Action Plan (MCAP). It just created a webpage dedicated to the subject. In December 2020, Mumbai became a member of the C40 Cities organisation. C40 Cities is a network of 97 cities across the world that are being encouraged to design and implement climate action plans in order to combat climate change by drastically decreasing greenhouse gas emissions.

Mumbai Climate Action Plan

The local body has begun developing the Mumbai Climate Action Plan in response to predictions that climate change may lead to extreme weather occurrences in the city (MCAP). It will focus on six areas to look at climate resilience with mitigation and adaptation methods  Waste management that is environmentally friendly, Greening and biodiversity in cities, Flooding in cities and water resource management, Increasing energy efficiency in buildings, The state of the air, Mobility that is long-term. The strategy is scheduled to be completed by November, in time for the UN Climate Change Conference (COP26).

Why is a climate action strategy required for Mumbai?

According to a research on Mumbai’s vulnerability assessment performed by the World Resource Institute (WRI) India, the city would confront two significant climatic challenges—Temperatures are rising and Flooding is expected as a result of extreme rain occurrences. According to the IPCC, climate change would cause sea level rise of 0.1 to 0.3 metres in at least 12 Indian coastal towns, including Mumbai, during the next three decades. According to a research released in February 2020 by McKinsey India, by 2050, Mumbai would see a 25% increase in the severity of flash floods and a 0.5 metre rise in sea level, affecting two to three million people living within one kilometre of the shoreline. Since 2007, the city has experienced a steady rise in temperature, owing to concrete, a lack of greenery, and high housing density. In these 14 years, the average temperature has risen by up to 1 degree Celsius. The number of really high rainfall occurrences has increased throughout the city. Each year, Mumbai has six heavy rain events (64.5–115.5 mm), five very heavy rain events (115.6–204.4 mm), and four extremely heavy rain events (> 204.5 mm). Mumbai’s climate action plan will aid in the creation of a vision and strategy for combating these climatic problems through mitigation and adaptation measures.

According to the data, Mumbai’s greenhouse gas emissions in 2019 were 34.3 million tonnes. The energy sector, which is mostly dependent on coal, accounted for 71% of the total. Transportation accounts for 24%, whereas solid waste management accounts for 5%. According to the statistics, coal accounts for 95% of Mumbai’s electricity, which must be replaced with renewable energy to reduce emissions.

The MCAP will focus on reducing greenhouse gas emissions by sectors and consumption patterns in the near term (2030), medium term (2040), and long-term (2050) to reduce the effect of climate change (2050). The following actions will be done to better adapt to growing climate threats in order to create a “climate resilient Mumbai.” Vulnerability analysis, Increasing the capacity of vulnerable communities to withstand disasters, Infrastructure that is climate-resilient, Natural systems that are healthy are being nurtured.
