Durban - The world needs a plan that is more ambitious than the Kyoto protocol to resolve the global warming issue. At the conference on the climate being held in Durban, the European Union has reiterated its position addressed at renewing the agreement, this time demanding the signatures of all countries and an agreement lasting until 2015 instead of 2020 as previously requested. The proposal was presented by the E.U.'s negotiator Artur Runge-Metzger who believes that "Kyoto alone cannot save the planet. Nations are abandoning the protocol." Adopted in 1997 the Kyoto Protocol came into effect in 2005 but was never signed by the USA or China, which alone are responsible for 11% of global CO2 pollution. "In our opinion there is no Kyoto protocol on the table" said the U.S. Special Commissioner for Climate Change Todd Stern. According to Washington in fact,  restrictions to greenhouse gas emission, currently established by the protocol only for more industrialized countries, must necessarily be extended also to developing countries, first among them to China, which last year ranked first as the most polluting country in the world even overtaking the United States. Other signatory countries such as Russia, Canada and Japan, are currently very critical and more orientated to abandon the agreement rather than to renew it. According to China the Durban summit on climate change leaves little to be optimistic about, as stated in an interview with state-owned Radio China International by Su Wei, Beijing's negotiator in South Africa. "Prospects are not optimistic," said Su, without providing details about the talks being held and the expected results. So as to find a solution to the problems posed by global warming, the 190 delegations will meet until December 9th in Durban. The objectives of this summit include the creation by 2020 of a $100 billion a year fund for climate to help poorer nations face the costs of reducing CO2 emissions.
