miljøeffekten

Miljøeffekten refers to the environmental effect of a process, product, activity, or policy. It encompasses changes in air, water, soil, ecosystems, climate, resource use, and human health, and can be positive as well as negative.

Assessment and methods: Life cycle assessment (LCA) is a standard method to quantify environmental effects across stages from raw material extraction to end of life. Environmental impact assessment (EIA) evaluates potential effects of a proposed project on the environment before it proceeds. Other indicators include carbon footprint, water footprint, ecological footprint, and biodiversity impact.

Scope and scale: Miljøeffekten is context-dependent, varying by geography, time, and scale; local emissions can have regional consequences, while global effects include climate change. Indirect effects via supply chains and behavioral changes are increasingly recognized.

Applications: Governments and organizations use analyses of miljøeffekten to guide policy, procurement, product design, and communications. Standards such as ISO 14040/14044 for LCA and national environmental impact assessments are used to ensure transparency and comparability.

Challenges: Data gaps, system boundary definitions, allocation rules, and trade-offs between environmental and economic objectives can complicate interpretation. Effective use of miljøeffekten often requires clear goals, robust data, and careful consideration of uncertainties and context.
