The ECO method was developed to aid environmental impact and cost optimisation of chemical synthesis pathways or processes suitable for the research and development (R D) stage. In order to represent terms of ecological as well as economic sustainability, three objective functions which incorporate (i) energy demand (EF), (ii) risks concerning human health and the environment (EHF) and (iii) costs (CE), were defined. Their calculation follows the life cycle approach and is based on the data available already in R D. Because the application of a comprehensive LCA is both, too complex and based on data which are partially not available at the R D stage, the determination of the three objective functions is based on the SLCA approach extended by economic issues. The key objectives are introduced below. 

In developing this clarification, the CG/HCCS carefully considered many different issues with regard to the possible application of the GHS. There were concerns raised about whether certain sectors or products should be exempted, for example, or about whether or not the system would be applied at all stages of the life cycle of a chemical. Three parameters were agreed in this discussion, and are critical to application of the system in a country or region. These are described below ...
