¥Both B-C and
C-E use discounting
¥C-E compares
several alternatives
¥C-E – Maximize benefits with fixed costs/resources, or
¥C-E – Minimize cost/resources with fixed benefit
¥C-E sometimes

cost data, i.e., often (environmental/ecosystem) costs are
better know than (environmental/ecosystem) benefits.
