The emission factors in this report are designed to help waste managers and others determine the GHG
impacts of alternative waste management options for clay bricks and concrete. These factors are additions to the
current factors described in the report, Solid Waste Management and Greenhouse Gases: A Life-Cycle Assessment
of Emissions and Sinks, available online at www.epa.gov/mswclimate/greengas.pdf. Readers are encouraged to
consult this report for more background on how life-cycle analysis is used to develop emission factors.
