Tough question there, David. Personally, I think there's a good chance we won't be able to stop global warming. Most people aren't taking it seriously.
With regard to your company, I wouldn't wait for Kyoto. You'd have a better chance marketing yourself as a green alternative, possibly as part of a green energy package consumers could purchase from their electric or gas companies. A law to encourage utilities to offer these alternatives is a much easier target than Kyoto.
To change our future, we would need to have a significant swing in public opinion. If I had a budget, here are some things I might consider:
-- Inspire national debate. Most warming deniers are uninformed and practically choose to bury their heads in the sand. Find a prominent figure and get him to challenge all comers to a televised debate. Lots of people don't like the oil companies; make dramatic challenges to their CEOs on TV. Warm-up with a debating tour of college campuses. Pick a spokesman who is squeaky-clean, has the brains of a Sagan, the debating skill of a Reagan, and the avoidance of doubt of Bush II.
-- We need to dispel the illusion of doubt. Most people aren't capable of making a decision unless it is black-and-white. Hire private investigators to examine the so-called scientists who deny global warming. Look for their funding sources. What you are looking for is dramatic stories of bias. It can't be a complicated issue; it must involve some egregious tale of pure greed that will make the news. Best possible result would be video tape of money being passed in a shadowy alley.

-- The average voter doesn't understand scientific debate - again, only black-and-white issues register. Any legitimate, well-meaning scientist who quibbles with details of climate theory should be contacted and urged to discuss further details with leading experts. It is correct for scientists to be extremely skeptical, but the public does not understand this and the deniers exploit it.
-- Mount a campaign to recruit celebrities. The sad fact is that people would rather listen to Paris Hilton than Al Gore. Happily, some celebrities are willing to participate. Talk to their agents and point out the publicity they can get by speaking a few words on climate change.
-- Find two really simple and dramatic stories illustrating just one thing that will go bad due to climate change. Publicize the hell out of these issues. If you saw "Inconvenient Truth" and watched the audience reaction, you probably realized that the statistics had little impact, but the polar bear drowning hit home. The first story should pick some cuddly creature going extinct. The second would find some UNDENIABLE way that climate change will hurt Joe Citizen's pocketbook. Hire an MTV director to make your video.
-- Target the politicians who are the biggest deniers and donate big to their opponents. If you can find a way to discredit them, so much the better.
-- Fund a research institution to create a news story daily. Each story should publicize a new discovery on climate change. Make sure that the results are sent to all the news outlets.
-- Coordinate and avoid mistaken predictions. Make sure every advocate realizes that the deniers will capitalize on any prediction that turns out to be wrong. Mount an email campaign to all climate scientists urging them to be cautious. The deniers love to find predictions that turned out wrong and use them to try to "prove" that all other predictions are wrong too.
-- Challenge the economic cost argument. People have accepted this without question or debate. Find entrepreneurs who are making green money and publicize them. Tag line: "green makes jobs". Or maybe "giant established concerns resist change that I easily overcame."
