Many scientists agree that the probability of a rare environmental disaster increases as the stock of greenhouse gases accumulate in the atmosphere. This column asks how much consumption current generations should be willing to sacrifice to reduce the risk of such a future catastrophe. If there were a way of immediately eliminating the risk of all future catastrophes, society should be willing to sacrifice 16% of its consumption in perpetuity to achieve this. A sacrifice of 5.8% of annual consumption could bring about a 30% reduction in emissions, in line with the reductions contemplated in agreements such as the Kyoto Protocol.

Energy-efficient technologies are an increasingly relevant policy priority, given growing consensus on the need to tackle climate change. This column examines the productivity benefits of adopting one such technology – LED lighting – for manufacturing firms in India. It finds that improved productivity resulting from LED lighting’s lower heat emissions makes adopting such technology far less costly than previous anticipated, particularly for labour-intensive firms in hot climates.

Policymakers in emerging economies such as India and China are ramping up efforts to confront pollution. A new study of the air purifiers market in China finds that people are willing to pay a lot to get rid of pollution, but the amount varies widely depending on a person’s income. This sort of metric can enable policymakers to assign values to their policies and guide their decisions.

Improved cooking stoves are increasingly seen as an important technology to address indoor air pollution. While laboratory experiments have shown that they could have big effects on smoke exposure and emissions, this column finds limited long-run health and environmental impacts of an improved cooking stove programme in Odisha. This indicates the importance of testing interventions in real-world conditions taking into account willingness to pay, usage, and changes over time.

Posted on: 15 Jun 2016

The driving restrictions policy that Delhi experimented with in January was implemented for a second time in April for a fortnight. This column finds that the policy lowered traffic congestion; the impact was notable in size and consistent over the two rounds. However, drivers managed to partly circumvent the policy legally, and the policy caused some disruption to economic activity.

Despite improvements to energy supply over the years, many Indian states still face frequent power shortages. Meanwhile, neighbouring countries such as Nepal and Bhutan have large reserves of untapped hydropower with the potential to meet unserved demand for energy in major load centres. Investing in interconnections could also contribute to significant reductions in carbon emissions. This column quantifies potential gains from an integrated South Asian power.

In response to a writ petition against pollution of the river Ganga due to industrial waste, the Supreme Court of India in 1987 mandated the tanneries in Kanpur, Uttar Pradesh to either clean up or shut down. This column finds that the ruling resulted in a significant drop in river pollution, which in turn reduced infant mortality in the city.
