China and U.S. Seek a Truce on Greenhouse Gases - NYTimes.com

  • China says the United States should reduce its greenhouse gas emissions by 40 percent below 1990 levels by 2020. The bill before Congress, which could be further weakened, now calls for less than a 4 percent reduction over that period.

Kyoto Protocol - What is the Kyoto Protocol?

  • Arguments against the Kyoto Protocol generally fall into three categories: it demands too much; it achieves too little; or it is unnecessary.
  • President Bush claimed that the treaty requirements would harm the U.S. economy, leading to economic losses of $400 billion and costing 4.9 million jobs.

China and U.S. Seek a Truce on Greenhouse Gases - NYTimes.com

  • They are, as President Obama’s chief climate negotiator puts it, “the two gorillas in the room,” and if they do not reach some sort of truce, there is no chance of forging a meaningful international treaty in Copenhagen later this year to restrict emissions.
  • Without the full participation of the United States and China, most negotiators believe that any agreement is doomed to fail.

Statement by Ambassador ZHANG Yesui at the UN General Assembly Informal Meeting on Climate Change

  • hina will as always take an active part in international negotiations on climate change, and make its share of contributions to tackling climate change.
    • developed countries should continue to shoulder the duty of adopting mid-term, quantified goals for large-scale emission cut;

    • developing countries should, according to their specific national conditions and with the support of the developed countries in capital and technological transfer, try their best to mitigate greenhouse gas emissions and strive to adapt to climate change;

    • an effective funding mechanism should be established to facilitate the financial support of developed countries to developing countries;

    • an effective mechanism should be installed to promote transfer of environment-and-climate-friendly technologies to developing countries and enhance their capacity for addressing climate change.

Budgets Falling in Race to Fight Global Warming - New York Times

  • The most immediate gains could come simply by increasing energy efficiency
  • Another area requiring immediate intensified work, Dr. Holdren and other experts say, is large-scale demonstration of systems for capturing carbon dioxide from coal burning before too many old-style plants are built.

Kyoto Protocol - Wikipedia, the free encyclopedia

  • The most notable non-member of the Protocol is the United States, which is a signatory of UNFCCC and was responsible for 36.1% of the 1990 emission levels.
  • Under the Protocol, 37 industrialized countries (called "Annex I countries") commit themselves to a reduction of four greenhouse gases (GHG) (carbon dioxide, methane, nitrous oxide, sulphur hexafluoride) and two groups of gases (hydrofluorocarbons and perfluorocarbons) produced by them, and all member countries give general commitments. Annex I countries agreed to reduce their collective greenhouse gas emissions by 5.2% from the 1990 level. Emission limits do not include emissions by international aviation and shipping, but are in addition to the industrial gases, chlorofluorocarbons, or CFCs, which are dealt with under the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer.

Emissions trading - Wikipedia, the free encyclopedia

  • Emissions trading (also known as emission trading or cap and trade) is an administrative approach used to control pollution by providing economic incentives for achieving reductions in the emissions of pollutants.


    A central authority (usually a governmental body) sets a limit or cap on the amount of a pollutant that can be emitted. Companies or other groups are issued emission permits and are required to hold an equivalent number of allowances (or credits) which represent the right to emit a specific amount. The total amount of allowances and credits cannot exceed the cap, limiting total emissions to that level. Companies that need to increase their emission allowance must buy credits from those who pollute less. The transfer of allowances is referred to as a trade. In effect, the buyer is paying a charge for polluting, while the seller is being rewarded for having reduced emissions by more than was needed. Thus, in theory, those who can reduce emissions most cheaply will do so, achieving the pollution reduction at the lowest cost to society.[1]

  • There are active trading programs in several air pollutants. For greenhouse gases the largest is the European Union Emission Trading Scheme.[2] In the United States there is a national market to reduce acid rain and several regional markets in nitrogen oxides.[3] Markets for other pollutants tend to be smaller and more localized.

Joint Implementation - Wikipedia, the free encyclopedia

  • Joint implementation (JI) is one of three flexibility mechanisms set forth in the Kyoto Protocol to help countries with binding greenhouse gas emissions targets (so-called Annex I countries) meet their obligations. JI is set forth in Article 6 of the Kyoto Protocol.[1] Under Article 6, any Annex I country can invest in emission reduction projects (referred to as "Joint Implementation Projects") in any other Annex I country as an alternative to reducing emissions domestically. In this way countries can lower the costs of complying with their Kyoto targets by investing in greenhouse gas reductions in an Annex I country where reductions are cheaper, and then applying the credit for those reductions towards their commitment goal.

Clean Development Mechanism - Wikipedia, the free encyclopedia

  • The Clean Development Mechanism (CDM) is an arrangement under the Kyoto Protocol allowing industrialised countries with a greenhouse gas reduction commitment (called Annex 1 countries) to invest in ventures that reduce emissions in developing countries as an alternative to more expensive emission reductions in their own countries. A crucial feature of an approved CDM carbon project is that it has established that the planned reductions would not occur without the additional incentive provided by emission reductions credits, a concept known as "additionality".
  • The CDM allows net global greenhouse gas emissions to be reduced at a much lower global cost by financing emissions reduction projects in developing countries where costs are lower than in industrialized countries
