Problem: Perform a cradle-to-use hybrid LCA for a $200 TV that will use 200 kWh of electricity per year (from a natural gas plant) over its 5-year lifespan. How many grams of NOx will be emitted over the life of the TV? From the CMUEIO LCA tool, $1M of economic activity in the "Other Audiovisual Manufacturing" sector will lead to 1.31 tons of NOx being emitted. Based on the NREL LCI database, generating a kWh of electricity from a natural gas power plant emits 4.776x10-4 kg of NOx.
