Chennai: A recent study conducted by the International Finance Corporation (IFC), a member of the World Bank, has projected a significant increase in greenhouse gas (GHG) emissions for Chennai by the year 2034. According to the study, the city’s GHG emissions are expected to surge by 31% from the current levels.
The citywide baseline emission study conducted for this year reveals that Chennai presently generates approximately 25.12 metric tons of carbon dioxide equivalent (MtCO2e). However, this figure is anticipated to rise substantially to 39.96 MtCO2e by 2034. The bulk of these emissions, around 76%, will originate from the built environment and energy production, followed by 18% from transportation and vehicular emissions, and 6% from solid waste management, primarily due to leachate from dump yards. IFC members presented the findings of the study to the Greater Chennai Corporation as part of their efforts to propose climate-friendly projects aimed at mitigating emissions. Greenhouse gases are known contributors to climate change, resulting in elevated temperatures, air pollution, and extreme weather events. They also exacerbate respiratory and cardiovascular diseases, heat-related illnesses, and mental health issues. Notably, methane emissions from leachate at Chennai’s major dump yards, Kodungaiyur and Perungudi, significantly contribute to GHG emissions.
The presentation took place within the framework of the Chennai City Climate Change Action Plan, developed by C40 Cities. Recently unveiled by Chief Minister M K Stalin, the action plan sets ambitious targets to substantially reduce GHG emissions by 2030. As Chennai grapples with the looming threat of rising GHG emissions, concerted efforts are needed to implement sustainable measures that can effectively curb emissions and mitigate the adverse impacts of climate change on the city and its residents. The IFC study underscores the urgency of adopting proactive strategies to address Chennai’s growing environmental challenges.
