The GACC talks about stoves that stretch goals which achieve significant, measurable health *and/or* environmental goals. With regard to environmental goals, the GACC makes a distinction between local and global. On the local level, it cites deforestation, erosion and desertification. On the global level, it cites black carbon and other greenhouse gases. Since all of us agree that CO2 is a greenhouse gas, this article from the New York Times might be of interest: http://www.nytimes.com/2013/08/20/science/earth/extremely-likely-that-human-activity-is-driving-climate-change-panel-finds.html?nl=todaysheadlines&emc=edit_th_20130820
To those who might consider any discussion on the stove list about climate change to be off-topic, let me ask: why do we design stoves the way we do? Do our designs only target health goals? Or do they also target environmental goals such as deforestation, erosion, black carbon and greenhouse gas emissions? Take note of the "and/or" in the GACC phrase. A stove might achieve only health goals, or a stove might achieve both health and environmental goals. Would it not make more sense if it achieved both? Asking such questions might be a bit controversial, but it is certainly not off-topic. It impacts in such a central way the thought process that lies behind stove design. Thanks. Paul Olivier Thanks.
