Used CO2

Process improvements can reduce Carbon Dioxide (CO2) air emissions. When that is done there can be left over permitted CO2 air emissions that can be sold to other users. In doing so a certain percentage of the original CO2 emissions are eliminated and cannot be sold. Hence a reduction in permitted CO2 air emissions overall.

Hungary last week carried out the first sale of certified emissions reductions (CERs) which Hungarian companies had already used to offset against their emissions in the European Union’s emissions trading scheme. These emission offsets are sold internationally to other companies.
