The industry has made an enormous investment since the 1990s to cut its emissions and to improve air and water quality. We feel we started before the others and did our work when we weren't required to do so as much as the others. Once we did our work, we were asked to do even more. That's why the reference should take into account what was previously done. I don't have any figures to give you, but we're talking about hundreds of millions of dollars in investments.
Every case should be studied, rather than establish an arbitrary rule setting a reference year. However, 1990 is the year when the forest companies in general started making significant improvements. Hundreds of millions of dollars in investments were made. So it would be fair to acknowledge the efforts made in the past.
