There is also criticism over the true impact of the Kyoto Protocol in the long run on reduction of greenhouse gas emissions because it is questioned how much developed countries can offset their emissions while developing countries continue to emit these greenhouse gases. There is criticism that the Kyoto Protocol does not do enough to address the issue of climate change and pollution in the long run. One criticism is that climate change is a unique environmental issue, but the Kyoto Protocol followed the format of the other international treaties (not necessarily useful for environmental issues) instead of promoting innovation in approaching the issue of global warming. Another criticism is that the Kyoto Protocol focuses too much on carbon emissions and doesn't address other pollutants, such as sulfur dioxide and nitrogen oxides, which either do direct harm to human health and/or can be addressed using technology. Some also claim that the Kyoto Protocol does not promote long-term solutions to reduce greenhouse gas emissions,  but rather short-term solutions in having countries try to meet emission reduction standards (either by lowering emissions or find ways to obtain trading credits). In the same way, there has been criticism that the Kyoto Protocol does not address the concentration of atmospheric greenhouse gases, but rather greenhouse gas emissions, focusing on the short-term over the long-term. The Global Warming Petition Project, also known as the Oregon Petition, is a petition urging the United States government to reject the global warming Kyoto Protocol of 1997 and similar policies. The petition's website states, "The current list of 31,487 petition signers includes 9,029 PhD; 7,157 MS; 2,586 MD and DVM; and 12,715 BS or equivalent academic degrees. The text of the Global Warming Petition Project reads:We urge the United States government to reject the global warming agreement that was written in Kyoto, Japan in December, 1997...The proposed limits on greenhouse gases would harm the environment, hinder the advance of science and technology, and damage the health and welfare of mankind...There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth. There are a large number of critics of carbon trading as a control mechanism. Critics include environmental justice nongovernmental organizations, economists, labor organizations and those concerned about energy supply and excessive taxation. Some see carbon trading as a government takeover of the free market.
