The article talks about creating a new plan after the Kyoto Protocol to deal with climate change. The new plan should be fair, cost-effective, and help with new technology. It should also fit with international trade rules and build on things we already have. The article suggests different ways to make this new plan, like setting strict emission limits for each country, making separate deals for different pollution areas, having global taxes on emissions, or connecting different permit systems. The main idea is to make a realistic and effective plan to fight climate change after Kyoto.
