CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...

Abstract Future ocean acidification mainly depends on the continuous uptake of CO 2 from atmosphere. The trajectory future atmospheric is prescribed in traditional climate projections with Earth system models, leading to a small model spread and apparently low uncertainties for projected acidification, but large global warming. However, policies such as Paris Agreement define targets terms warm...

Climate change is the exemplary global public good, because each country’s emissions of greenhouse gases contribute cumulatively to the increase of the overall concentration, and each country’s abatements entail higher cost than benefit, unless effective concerted collective actions

The 1987 Montreal Protocol on Substances that Deplete the Ozone Layer is a landmark agreement that has successfully reduced the global production, consumption, and emissions of ozone-depleting substances (ODSs). ODSs are also greenhouse gases that contribute to the radiative forcing of climate change. Using historical ODSs emissions and scenarios of potential emissions, we show that the ODS con...

The purpose of the purposed workshop is to assemble a selection young economists whose research has featured new thinking on challenging theoretical and empirical questions bearing on the design and implementation of practical and economically efficient programs aimed at stabilizing the rise in radiative forcing due to the increased concentration of greenhouse gases (GHGs) in the Earth’s atmosp...

S uppose that averting dangerous climate change meant limiting the concentration of greenhouse gases (measured in parts per million, or ppm, by volume) in the atmosphere so that the world faced a temperature increase of no more than 2°C—a goal endorsed by the European Union. What would it take to meet this goal? Because of “climate uncertainty,” we cannot be sure. We can meet the goal with prob...

Regulating greenhouse gas emissions through cap-andtrade programs appears inevitable in the United States and conflicts among stakeholders are likely to result in new litigation . The European Union Emission Trading Scheme and U .S . Acid Rain Program can be examined as exemplars to identify the stakeholders of a cap-andtrade program and the types of conflicts that are likely to emerge . Severa...

We investigate the issue of “dangerous humanmade interference with climate” using simulations with GISS modelE driven by measured or estimated forcings for 1880– 2003 and extended to 2100 for IPCC greenhouse gas scenarios as well as the “alternative” scenario of Hansen and Sato (2004). Identification of “dangerous” effects is partly subjective, but we find evidence that added global warming of ...

Stabilizing global greenhouse gas concentrations at levels to avoid significant climate risks will require massive "decarbonization" of all the major economies over the next few decades, in addition to the reduced emissions from other GHGs and carbon sequestration. Achieving the necessary scale of emissions reductions will require a multifaceted policy effort to support a broad array of technol...
