Kyoto may be one of those "inadequate goals" that have the danger of lulling people into thinking a problem is being addressed, when the full scope is not. However, it is also a "first step" that introduces carbon emissions trading to the world, and market incentives to start the reduction of economic carbon intensity. Renewable energy technologies could greatly benefit - the protocol specifically states that parties may conduct:
Research on, and promotion, development and increased use of, new and renewable forms of energy, of carbon dioxide sequestration technologies and of advanced and innovative environmentally sound technologies;(Article 2, paragraph 1.iv)
Perhaps these developments will be enough to move economies to real alternatives; a more drastic approach that has potential to achieve the full needed reductions is the Contraction and Convergence proposal.
