India's largest banks are conducting audits to assess their own and borrowers' carbon footprints as they face increasing pressure from regulators and investors to align their ESG reporting with global standards. India, the world's third-highest greenhouse gas polluter, aims to achieve net-zero emissions by 2070. The country's financial sector lags behind others in reporting on lending-related emissions. About 25%-35% of Indian bank loans are exposed to carbon-intensive sectors.
