The potential of any residential combustion improvement to be accepted and long lasting in a community, and thus deliver projected health and climate benefits, depends strongly on spatial resource constraints and device end-uses. To estimate this potential, we will (1) Produce a global resource-driven map of current emissions and plausible interventions for all residential uses of solid fuel; (2) Improve understanding of emissions attributable to space heating by adding measurements to four residential-energy projects in Alaska, Nepal, Mongolia and China; (3) Incubate a Regional Testing and Knowledge Center and demonstrate successive improvement in interventions; (4) Model how current emissions and plausible interventions affect local outdoor concentrations and global radiative forcing.
We will use GIS modeling of forest resources and population, real-time measurements of emission factors and indoor air quality, and seasonal assessments of fuel use to produce a map of realistic emission and intervention locations. Dispersion modeling and climate modeling with a detailed aerosol module will be used to assess impacts.
Outputs expected from this project include presentations and papers in atmospheric science, environmental health, building science, development, land-use, and climate policy literature on the following topics: Fuel use and stove choice; Global emission and intervention model constrained by seasonal fuel-use observations and proximity to forest and agricultural waste; Health implications of residential stove interventions; Relationship between real-time indoor-air and emission measurements compared with ventilation measurements in 4 locations; Methods for using real-time stove use data to estimate fuel consumption for heating; Estimated contribution of heating emissions to air quality, and potential for mitigation with synthesis of observations in 4 locations; Development of regional testing center and appropriate division of activities between academic and “on-the-ground” partners; Generalized relationship between population density and locally-generated pollutant concentrations, and estimates of related exposures; Climate mitigation potential from residential fuel improvements; Differences in climate response between models with different aerosol representations. The expected outcome is an improved ability to make decisions with a framework for quantifying costs (by identifying appropriate interventions and their relative costs) and benefits (by assessing energy savings, time savings, health related pollutant concentration changes and climate impacts) of changes in residential solid-fuel use.
