Clean Development Mechanism
The Kyoto Protocol includes an arrangement for reductions to be "sponsored" in countries not bound by emissions targets. This is the Clean Development Mechanism.
The Mechanism is loaded with complicated details and acronyms, but in simplified form it works this way: Industrialized countries pay for projects that cut or avoid emissions in poorer nations and are awarded credits that can be applied to meeting their own emissions targets. The recipient countries benefit from free infusions of advanced technology that allow their factories or electrical generating plants to operate more efficiently and hence at lower costs and higher profits, and the atmosphere benefits because future emissions are lower than they would have been otherwise.
