One Way to Solve Climate Change: Cleaner Cookstoves

6 years ago

Can a simple stove help solve something as complex as climate change? Children-with-clean-stove-Lisa-Feldman1 The United Nations Foundation and its partners at the U.S. State Department, the U.S. Environmental Protection Agency, and other institutions and organizations think so - at least, in part, which is why they've launched the Global Alliance for Clean Cookstoves. This new partnership between government agencies, non-profit organizations, international aid groups and corporations aims to replace 100 million dirty stoves in developing countries with cleaner versions by 2020. How can a lowly cookstove play such an important role in the climate debate? REDUCE BLACK CARBON: The traditional cookstoves used in Asia, Africa and parts of Latin America rely on "biomass" like wood, cow dung, and coal. When any of these fuels is burned, they produce soot, also known as "black carbon." Biomass cooking accounts for 20 percent of the world’s emissions of black carbon, which some scientists believe is the second largest contributor to climate change after carbon dioxide. Black carbon is so powerful because it is extremely effective at absorbing sunlight -- 1 million times more effective than carbon dioxide (CO2), in fact. Black carbon warms the atmosphere and creates a "greenhouse effect" by absorbing thermal infrared radiation from the ground and within clouds. Plus, because it directly heats surfaces on which it falls and reduces the amount of sunlight surfaces reflect back into the atmosphere, black carbon accelerates the melting of Arctic sea and land ice, glaciers, and seasonal snow cover. REDUCE POLLUTION: Another important reason to improve cookstoves is because existing stove designs release toxic smoke that make people sick. That's especially true for women and young children, who spend a larger share of their time indoors in the poorly ventilated spaces where the stoves are used. Cookstove smoke contributes to a range of chronic illnesses and acute health impacts such as early childhood pneumonia, emphysema, cataracts, lung cancer, bronchitis, cardiovascular disease, and low birth weight. The World Health Organization estimates harmful cookstove smoke to be the fourth worst overall health risk factor in developing countries. KEEP WOMEN AND CHILDREN SAFE: Cleaner cookstoves would keep women and children safer, too. Because women and children are primarily responsible for gathering fuel, they often have to walk great distances in dangerous, barren and conflict-ridden areas to scrape together the minimal amounts of fuel available. Cleaner cookstoves would reduce the demand for fuel and how often women would need to search it out, lessening the likelihood that they would become victims of rape and robbery. STOP DEFORESTATION: Forests would benefit, as well, since less wood would be harvested as more and more people switched to more fuel-efficient stoves. Though the Alliance's initial goal is to provide stoves to 100 million homes, the broader aim is to establish a sustainable market for clean cookstoves and cleaner fuel that would provide new economic opportunities that help build sustainable communities. So not only would cleaner cookstoves reduce climate change, improve public health, and safeguard women and children; they would also create local jobs as people learn to design, manufacture, and distribute the stoves in their communities. As simple as it might sound to replace dirty stoves with clean ones, challenges abound. Not only do millions of new stoves need to be made and distributed, but people will need to overcome cultural barriers before they decide to use them. In some cases, women will need to learn how to cook somewhat differently; their husbands may need to learn to like different-tasting foods; and women used to spending their time looking for fuel may need to find other occupations. Hopefully, through effective social marketing, engineering, appropriate technology, and creative collaboration among local groups and national and international institutions, the goal of "100 million by 2020" will be reached.
