ECO.10:4.3 - Return the consequence to the actual purpose

First state whether total use after the response is lower than, equal to or higher than use without the improvement. Then, if useful, report the fraction of the fixed-output saving offset by the induced response: divide the response-induced change by the fixed-output saving. This percentage requires a positive, well-defined saving. Otherwise report the separate totals and the induced change. The percentage here uses the declared resource account; an operating-only rebound estimate and an estimate including equipment or transition burdens have different bases. A response which exceeds a positive fixed-output saving is the backfire case.

Compare responses appropriate to the purpose. A growth objective may welcome more valuable output. A resource cap may require allocating the released capacity or controlling aggregate use as well as improving efficiency. Each intervention has its own feasibility, cost and affected interests; the rebound calculation does not select a policy automatically.

Return a choice, a conditional operating limit or the observation that would change it. Stop when the comparison already distinguishes the feasible alternatives.
