    • Toward a useful architecture for climate change negotiations 

      Jacoby, Henry D.; Schmalensee, Richard.; Sue Wing, Ian. (MIT Joint Program on the Science and Policy of Global Change, 1999-05)
      Years of hard bargaining have failed to produce a policy architecture to adequately address the complexities of climate change. Very likely, such a structure will have to be sought though improvement of the partial ...
    • Tradable permits for greenhouse gas emissions : a primer with particular reference to Europe

      This paper is written as part of a two-year study of climate change policy choices facing Sweden, conducted under the auspices of the Center for Business and Policy Studies in Stockholm. As such, it aims to be a primer on ...
    • Transient climate change and net ecosystem production of the terrestrial biosphere

      The Terrestrial Ecosystem Model (TEM version 4.1) is applied to assess the sensitivity of net ecosystem production (NEP) of the terrestrial biosphere to transient changes in atmospheric CO2 concentration and climate in the ...
    • Transient climate change and potential croplands of the world in the 21st century 

      Xiao, Xiangming.; Melillo, Jerry M.; Kicklighter, David W.; McGuire, A. David.; Tian, Hanqin.; e.a. (MIT Joint Program on the Science and Policy of Global Change, 1997-05)
      A cropland distribution model, which is based on climate, soil and topography, is applied to estimate the area and spatial distribution of global potential croplands under contemporary climate and to assess the effect of ...
    • Transparency in the Paris Agreement 

      Jacoby, H.D.; Chen, Y.-H.H.; Flannery, B.P. (MIT Joint Program on the Science and Policy of Global Change, 2017-02)
      Establishing a credible and effective transparency system will be both crucial and challenging for the climate regime based on the pledge and review process established in the Paris Agreement. The Agreement provides for ...
    • Turkish Energy Sector Development and the Paris Agreement Goals: A CGE Model Assessment 

      Kat, Bora; Paltsev, Sergey; Yuan, Mei (MIT Joint Program on the Science and Policy of Global Change, 2018-07)
      In the 2015 Paris Agreement, Turkey pledged to reduce greenhouse gas (GHG) emissions by 21% by 2030 relative to business-as-usual (BAU). However, Turkey currently relies heavily on imported energy and fossil-intensive power ...
    • U.S. Greenhouse Gas Cap-and-Trade Proposals: Application of a Forward-Looking Computable General Equilibrium Model 

      Gurgel, Angelo C.; Paltsev, Sergey; Reilly, John M.; Metcalf, Gilbert E. (MIT Joint Program on the Science and Policy of Global Change, 2007-06)
