India needs a standard metric for the social cost of GHG

It is a well-established fact that consequent to climate change, countries face a slew of adverse impacts; damages that are not adequately quantified while assessing these impacts. Developing economies like India are going to bear an unduly larger share of such impacts. We should aim at not only developing a metric for quantifying the social cost of GHG but also of other components so that the impact of local air pollution, too, can be holistically monetised from a policy formulation perspective. It is time that such complex matters attract a more science-based approach, thereby obviating any kind of biases.
