From the NY Times Magazine’s profile of Hillary Clinton:
In September 2010, Clinton announced the creation of a partnership led by the United Nations Foundation to provide 100 million cleaner and more efficient stoves around the world by 2020, and she has since used every opportunity to implore world leaders to adopt policies to encourage their useFrom a new working paper by Rema Hanna, Esther Duflo, and Michael Greenstone (via Shankar Vendantam):
We find no evidence of improvements in lung functioning or health and there is no change in fuel consumption (and presumably greenhouse gas emissions). The difference between the laboratory and field findings appear to result from households’ revealed low valuation of the stoves. Households failed to use the stoves regularly or appropriately, did not make the necessary investments to maintain them properly, and usage rates ultimately declined further over time. More broadly, this study underscores the need to test environmental and health technologies in real-world settings where behavior may temper impacts, and to test them over a long enough horizon to understand how this behavioral effect evolves over time.
