Shayak Sengupta et al. ,Subnational implications from climate and air pollution policies in India’s electricity sector.Science378,eabh1484(2022)

Objective:

  • A clear understanding of the emissions of GHG and air pollutants from the Indian grid at a subnational scale has not existed before now.

Case:

  • India

Methodology:

  • Reduced-order dispatch model

Data Source

  • CO2, SO2

Findings:

  • Average nationawide CO2 and SO2 emissions intensities for electricity in India fail to capture the heterogeneity between states
  • The dominant global feature of embodied land-use emissions are large exports of emissiosn from countries such as Brazil, Indonesia, Argentina, Austrilia and Canada to consumers in developed regions such as the US, Europe and Japan
  • A carbon tax results in a little short-term emissions reductions because there is not enough dispatchable lower emission spare capacity to substitute coal
  • The implementation of sulfur controls will likely result in large reductions of SO2 emissions
  • The dispatching plants at the regional level would lead to a small increase in both SO2 and CO2 emissions with heterogeous cost effects on states.
