TOOLS & METHODSTOOLS & METHODS
Registration, Evaluation and Authorisationof CHemicals
Merging of 2 current systems for new (1980-) and existing (-1980) chemicals into a new system
Registration of all chemicals >10 tonne/year in a central database
Main responsibility for collecting and evaluating data lies on the producers and importers of chemicals
Legislation 2 years from now (2007?)
Progressively installed, completed 2018
EU New chemicals policy - REACH

TOOLS & METHODSTOOLS & METHODS Life Cycle Assessment (LCA) + ERA
LCA
Including all activities from cradle to grave
Potential environmental impacts from activities, e.g.:Resource useGlobal warmingWastes
ERA
including production, formulation, use and waste of chemical
Risk of impacts on ecosystems (living organisms) from releases of a chemical product,
Difficult to include direct effects of substances on ecosystems and humans

TOOLS & METHODSTOOLS & METHODS Costs analysis
Included costs depend on functional unit (benefit)
Costs for the end customer sales price+ costs during use+ disposal costs
Varies depending on e.g. the durability of the product

PUBLICATIONSPUBLICATIONS Other findings
Eco-efficiency analysis not time consuming if based on collected LCA data
Environmental costs found to be a relatively large part of the total costs of the studied colorants
Environmental costs of the surfactants (used in the colorants) 4,5% – 6,5% of the sales price (~1% normally reported)
