Abstract

This study presents a comparative analysis of methane (CH₄) emissions between Kolkata and the Sundarban Delta from 2019 to 2024, using data from Sentinel-5P. The research identifies significant trends and correlations in methane emissions, influenced by urbanization and ecological factors. Time series analysis reveals distinct seasonal patterns and trends, with Kolkata showing a steady increase in emissions due to industrial activities, while the Sundarbans exhibit relatively stable CH₄ levels, attributed to its mangrove ecosystem. Statistical analysis, including ANOVA and correlation tests, highlights the significant differences in emissions dynamics between the two regions. The findings underscore the need for transboundary environmental policies to address divergent emission trajectories and emphasize the importance of coordinated efforts between scientific communities and policymakers in India to mitigate climate change impacts. This research provides critical insights for developing targeted strategies to balance urban development with ecological preservation.
