title: Urban and country level greenhouse gas emissions and carbon footprints: A comparative study of a megacity, Delhi and India.
abstract: This paper describes the contribution and comparison of carbon footprints of megacity Delhi with that of India over the period from 1990 to 2000. Two published studies were taken as base to calculate carbon footprint in terms of CO2 equivalents (CO(2)-e) by taking into account CO2, CH4 and N2O emissions mainly from transport, power plants, domestic, industries, agriculture and waste sectors. It is found that carbon footprints have increased more in India (-45%) in comparison to Delhi (-33%) between 1990-2000. However, the average per capita carbon footprints at India level is less than for Delhi. Also, carbon footprint per km area in Delhi is - 40 times to that for India. In India (2000) the contribution to carbon footprint's share primarily comes from power plants, industries and agriculture sector whereas it comes from power plants and transport in case of Delhi. Various control measures taken into account in Delhi during 1990-2000 have resulted in decreasing share of CO2 in the total greenhouse gas (GHG) emissions in comparison to what appears at India level. It indicates that suitable policy measures and norms are required to be implemented at India level to control other GHGs along with CO2 to reduce net carbon footprints at the country level.
