India's logistics sector, accounting for 14.4% of its GDP, is set to grow due to increased global trade and eased trade tariffs. This expansion, however, raises concerns about CO2 emissions from freight transport across road, aviation, and maritime channels. To mitigate environmental impacts, integrating Marginal Abatement Cost (MAC) into the Cost-Benefit analysis is vital. MAC measures the cost-effectiveness of reducing emissions, expressed in dollars per tonne of CO2, aligning economic growth with sustainable practices.‍
