The reduction goals announced by the nations responsible for the bulk of the world's greenhouse gas emissions are likely to fall short of what many scientists say is needed to limit the disastrous effects of climate change, AP quoted a U.N. official as saying today. Janos Pasztor, the top climate adviser to Secretary-General Ban Ki-moon, however, said the commitments, which largely reaffirm their previous pledges, make it highly unlikely the world can meet the goal set at the Copenhagen climate conference of preventing temperatures from rising more than 2 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels. «It is likely, according to a number of analysts, that if we add up all those figures that were being discussed around Copenhagen, if they're all implemented, it will still be quite difficult to reach the 2 degrees,» Pasztor told The Associated Press. «That is the bottom line, but you can look at it negatively and positively. The negative part is that it's not good enough,» he said. «The positive side is that for the first time, we have a goal, a clear goal that we're all working toward, and we know what the commitments are. ... Before we would just talk.» Pasztor said some 50 nations _ including China, the United States and 27-member European Union _sent in their commitment letters by the Feb. 1 deadline set at the Copenhagen climate conference in December. More such letters were expected to continue trickling in over the next several days. The goals submitted to the United Nations outline voluntary plans for rolling back their heat-trapping gases from fossil fuel burning. The commitment letters were intended to get an idea of how far the nations most responsible for global warming might be willing to go, in a step toward pushing for a legally binding pact later this year. China has pledged to reduce the growth rate of its emissions _ not make absolute cuts _ by up to 45 percent from 2005 levels by 2020. India also pledged to reduce the growth rate of its emissions by up to 25 percent from 2005 levels by 2020. The United States stuck to President Barack Obama's pledge to cut its absolute carbon emissions by about 17 percent by 2020 below 2005 levels _ setting a precedent for China and India to scrap the baseline 1990 emissions levels used in previous U.N. climate negotiations. The European Union has pledged to cut its carbon emissions 20 percent below 1990 levels by 2020, and to cut 30 percent if other nations deepen their reductions. The Copenhagen Accord brokered by Obama, and more than two dozen other world leaders fell far short of the legally binding treaty that had been the goal of the two-week conference, but included collective commitments by developed countries to provide billions of dollars in emergency funds to help poor countries adapt to climate change.
