Percentage reduction

1. The U.S. 1987 baseline for dioxins / furans will be known when the Dioxin Reassessment Report is finalized.

2. Because there is no BTS numerical challenge target, there is no baseline.

3. There is no reduction target for HCB and B(a)P for the U.S.; the U.S. challenge is written as follows, “seek reductions in releases.”
