QUANTIFYING THE CLIMATE, AIR QUALITY AND HEALTH BENEFITS OF IMPROVED COOKSTOVES: AN INTEGRATED LABORATORY, FIELD AND MODELING STUDY

Description:

Expected results and outputs include: extensive dataset of in-field and laboratory emissions data for traditional and improved cookstoves; parameterization to predict cookstove emissions from drive cycle data; indoor and personal exposure data for traditional and improved cookstoves; and model predictions of the climate, air quality, and health impacts for a range of feasible cookstove interventions. The research will provide policy relevant metrics to compare a range of feasible scenarios that will quantify the potential tradeoffs between climate, air quality and health benefits. Ultimately, it will provide new insight and tools to improve air quality management decisions and climate evaluations.

Purpose/Objective:

Emissions from open fires and rudimentary, traditional cookstoves have significant effects on climate, air quality and human health, but the design and implementation of cookstove interventions have been hampered by critical knowledge gaps.  This project will develop and apply a framework to quantify climate, regional air quality, and indoor air quality benefits of cookstove interventions. Technical objectives include: measure in-use emissions from traditional and improved cookstoves at sites in China, India, Kenya, and Honduras selected to span a wide range of technology/fuel/cooking practices; quantify personal and indoor exposure to household cookstove emissions in China and India; collect in-use stove activity and drive cycle data; characterize a full suite of gas and particle emissions from cookstoves in the laboratory field using state-of-the-art instrumentation; develop a semi-empirical, drive-cycle based parameterization to link laboratory and field data; quantify and parameterize the atmospheric evolution of cookstove particle emissions from source to global model grid scale; develop and evaluate a set of feasible cookstove interventions and associated emission inventories based on ISO Tier categories; perform global and regional modeling to estimate climate (radiative-forcing estimates as well as temperature and precipitation changes) and air quality (PM, O3) impacts of different cookstove scenarios; model indoor air pollution, intake fractions, and personal exposures for cookstove interventions; perform preliminary health impacts assessment of proposed interventions; and compare cost-effectiveness of cookstove interventions to other strategies for climate, air quality, and/or health mitigation.
