What year does the Montreal Protocol finally phase out HCFCs?
A: 2010
B: 2020
C: 2030
D: 1995

参考答案: C

本题解释:
Most CFC use and production was phased out in 1995, while some other
substances and derivatives will be phased out in 2010, and the less active
HCFCs will be phased out in 2030

Simple payback takes the cost of an item or strategy and divides that number
by the yearly savings that product or strategy creates. If replacing a
CFC-based system costs $150,000 but saves a property manager $50,000 a
year, the project will have a simple payback period of 3 years.

Life-cycle-analysis (LCA, also known as life cycle assessment, ecobalance,
and cradle-to-grave analysis) is the investigation and valuation of the
environmental impacts of a given product or service caused or necessitated
by its existence.

Life cycle assessment evaluates a products “environmental impact”.
