US President Barack Obama acknowledged that disappointment over the results of the Copenhagen climate change summit was justified. He expressed that although the outcome was not ideal, it was better than a complete collapse of the conference. Other leaders, such as Sweden and British Prime Minister Gordon Brown, criticized the accord as a disaster for the environment and flawed, respectively. The agreements reached at the summit did not meet the original goals to reduce carbon emissions and combat global warming, as differences between wealthy nations and developing economies proved difficult to overcome during negotiations. Some people specifically blamed China for the lack of progress in agreeing to significant reductions in global emissions. British Environment Minister Ed Miliband accused China of sabotaging efforts, while Beijing accused London of trying to create division among developing countries on the issue of climate change. Although Obama did not accuse anyone directly, he mentioned that the Chinese delegation was not participating in negotiations until he intervened. Obama stated that when tensions were high and negotiations were on the verge of collapse, calmer heads ultimately prevailed. Obama reached an agreement with China, India, Brazil, and South Africa during the last hours of the conference after arranging a one-on-one meeting with the leaders of these nations. He mentioned that they were able to agree on non-binding targets for all countries, including China and India, which are expected to be the world's biggest emitters in the future.
