NEPfNEPd 258 0125 20 5 so NEP of tropical rain forest is over 20 times bigger than the NEP of an area of desert scrub. This makes sense as there is much more fauna in a rainforest that can contribute to ecosystem production as opposed to a more barren area of desert scrub. 2. LCIA 23(1) + 23(23) +240(1800) + 1(4600) + 13(5700) = 511,252 CO2 equivalent potential in a 100- year time frame. 1) Information on the actual effects of resource depletion and environmental emissions is often unquantifiable. Although is data for the estimates of the global warming potential of various greenhouse gasses, such data is not available for all types of environmental impacts and resources. A solution to this shortcoming is more research done by companies and academia—companies who are concerned with LCA should collect and present environmental data along their existing product’s life cycles and use this data to extrapolate and infer the impacts of future products.
