IEE to continue partnership with World Bank on improved cookstoves in Ethiopia. The new project focuses on the importance of household air pollution from burning fuelwood inside the home. Such pollution affects 3 billion people per year and is estimated to kill over 4 million people per year, making it one of the most important causes of premature death in the developing world.  IEE will test whether the Mirt stove reduces indoor air pollution and improves lung function of women and children.


IEE in partnership with the Forest Park Conservancy continues joint work on the value of Forest Park ecosystem services, with a series of focus groups across Portland summarized in a report released in September 2016 and a stakeholder workshop conducted in October 2016.
