Bangladesh faces major environmental challenges due to rapid industrialization and urbanization, which have increased greenhouse gas (GHG) emissions. This study analyzes the relationships between climate change indicators–such as temperature changes, rainfall patterns–and emissions of CO \(_2\) , CH \(_4\) , and SO \(_2\) . Using secondary data from government and private sources, we applied correlation and regression analyses to explore these links. Results reveal strong correlations: CO \(_2\) emissions are closely tied to rising temperatures, while CH \(_4\) and SO \(_2\) emissions significantly affect precipitation and extreme weather events. Historical emission trends were used to project future climate scenarios. The findings emphasize the urgent need for policy reforms to reduce GHG emissions and support sustainable urban development. This research aids policymakers, urban planners, and stakeholders in advancing sustainable energy, environmental protection, and green technologies. Ultimately, it advocates for a low-carbon economy and resilient urban infrastructure to mitigate climate change impacts in Bangladesh.
