An exergy-based method for allocating carbon dioxide emissions from cogeneration systems
Many companies, government agencies and researchers have sought means to allocate emissions for cogeneration systems. Some work has been carried out in this area, but the results obtained thus far are not universally accepted, and often are inconsistent, overly complex and difficult to use, and not based on sound reasoning. In this paper, an exergy-based method for allocating emissions for cogeneration systems is described and compared with other methods (e.g., energy- and market-based approaches). The results should be of most benefit to designers of energy systems, and to decision and policy makers in companies and government.
