The approach matches most of the dialogue about energy and conservation: predictions about energy use and its consequences are generally delivered in the aggregate. But behind these predictions lie everyday activities and decisions and everyday living experiences. This week, I look at a different kind of approach to sustainability, one that looks more closely at individuals.
The individual problem comes down to unwillingness as well as inability. Policy can shift both to change decisions.
Consider the unwillingness to choose the most efficient/ least-damaging technology. This is understandable in many ways. Environmental damage is an externality. People choose to buy diesel cars, and people suffer the increasingly thick smog blanketing Delhi. Do they suffer the smog and decide to buy a CNG rather than a diesel car? No — why would they? The smog is public — an externality from others’ decisions — and the benefits of lower-cost transport are private. There is no reason to be the first to give up the diesel when everybody else would share the benefits.
So the question is how to internalise this externality? This goes beyond reducing subsidies for more-polluting fuels, as I mentioned last time, to actually increasing the costs of fuel use in proportion to its contribution to pollution. There are also rewards for emissions reduction as in the clean development mechanism. India should actively support the implementation of the CDM by making the certification process streamlined while remaining credible.
Creating awareness and peer pressure can also help. Websites like Carbon Monitoring for Action (www.carma.org
