PTDR facilities also offer benefits in the reduction of the generation of greenhouse gases ("GHG") and thus potentially generate carbon credits. Carbon credits are GHG emission reductions that are created when a project reduces or avoids the emissions of GHGs, relative to what would have been emitted under a 'business as usual' scenario. There are a number of viable GHG reduction scenarios applicable to the PTDR technology:


Reduction of CO2 and Nitrous Oxides: When synthesis gas is used for thermal and/or electrical energy production the amount of GHG’s produced, is approximately ½ of that produced by the combustion of coal and/or fuel oil for an equivalent amount of energy produced.
Avoidance of landfilling materials containing organic constituents avoids the production of methane which is has a Global Warming Potential (GWP) that is 22 times that of CO2.
For PTDR systems that are installed at the site where the waste feedstocks are produced (such as the PTDR-100 systems), there will be GHG reductions associated with the avoidance of transportation to the disposal sites.

Carbon credits are measured in units of certified emission reductions (CERs). Each CER is equivalent to one tonne of carbon dioxide reduction. Depending on the ‘business as usual scenario’, the waste stream(s) processed and the PTDR system type, hundreds to thousands of CERs can be generated in a given year.
