• Life Cycle Assessments• Environmental Product Declarations• Eco-efficiency analyses• Environmental Risk Assessments• Environmental Impact Assessments• Transport and energy analyses

Provide different environmental services, such as:


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



Data evaluation

Exposure assessment

Risk Characterisation Ratio

RCR = PEC / PNEC

Effectassessment

PEC = Predicted Environmental Concentration RCR < 1

No risk!

PNEC = Predicted No-Effect Concentration

STRATEGIESSTRATEGIES

Flows of water and contaminants in a mining area

ERA of the use of a flotation agent


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

Societal weighting- based on public and expert opinions on the relative importance of environmental, health and safety impact categories

- differs between regions and countries

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)
