Firstly, just to complicate matters even further, there are two types of offsetting. One is where you—which is I think what the Hon Scott Simpson was referring to—buy an offset in the form of forestry. There's also something called offset forestry, which is where you have an existing forest in one part of the country, and you plant up another, and then you cut down the other forest. So it's about flexibility in land use. The idea is that if I want to cut down this forest over here permanently and convert it to, say, dairy, or some other land use, then in order to avoid the liability of losing that forest I have to plant up another. So the new forest is the offset against the one that I've cut down.
