What products will reduce global warming?

I have friends who are still in denial about global warming. These card-carrying members of the Flat Earth Society believe concern about global warming is just a conspiracy by liberals and tree huggers to subvert free trade even though the evidence convincingly shows that green house gasses are melting the ice caps.  Indeed, a segment on Sixty Minutes last night showed how much of the O'Higgins Glacier in Patagonia, Chile, has melted away as has a lot of the ice that sustains Penguins in the Antartic. And in a rebuke of the Bush Administration, which recommends membership in the Flat Earth Society, the Supreme Court issued two rulings favoring clean air advocates and proponents of cutting green house gas emissions. 

So I want to pose a question: what products do you or your company produce that will help cut down on green house gases? What ideas do you have for products and how strongly do you believe or disbelieve that  global warming is a problem?
