Using the budget constraint to monetarise impact assessment results

摘要: Abstract Recent developments in Life Cycle Impact Assessment (LCIA) provide a basis for reducing the uncertainty monetarisation of environmental impacts. The LCIA method “Ecoindicator99” provides impact pathways ending physical score each three safeguard subjects humans, ecosystems, and resources. We redefine these damage categories so that they can be measured terms Quality Adjusted Years (QALYs) impacts on human well-being, Biodiversity Hectare (BAHYs) monetary units resource productivity. value QALY derived from budget constraint, i.e. fact average annual income is maximum an person pay additional life year. Since by definition life-year lived at full constraint determined as potential economic production per capita well-being. determine this to 74,000 EUR with estimate 62,000 84,000 EUR. This corresponds well 74,627 willingness-to-pay ExternE project. Differences other estimates explained inherent biases valuation approaches used derive estimates. ecosystems expressed or QALYs, share our well-being we are willing sacrifice protect ecosystems. While trade-off should preferably done choice modelling, only one such study was found level abstraction allows us relate BAHYs QALYs units. Stressing necessity studies, resort suggest temporary proxy 1400 EUR/BAHY (or 52 BAHY/QALY), range 350 3500 EUR/BAHY. practical consequences above-described values has been investigated combining them midpoint two recent methods, thus providing new option expressing results both midpoints optional between endpoint.
