"What does "net zero" mean ? "
===
Net zero means, that you can have emissions, as long as you also have sufficient greenery, which absorbs it, so they balance out.
If we shut down half of our industry and plant trees in their places, we will be doing just fine, according to Kyoto.
Of course Kyoto also says that countries like China and Russia do NOT have to control their emissions, because they are "developing nations", so we need to cut back more, to make up for their pollution.
Finally found it....
Seattle IS attempting to provide "green" energy, but for now, Seattle City Light's web site says they are buying offsets & importing wind generated electricity plyus maximizing hydro generated electric. (keeping the problem upstream or pushing it downstream)

A mini-version of Kyoto, where one can buy "credits" without actually having to do anything.
