ressourceeffektivitet

Ressourceeffektivitet, or resource efficiency, refers to the economic use of materials, energy, water, and other inputs to produce goods and services with minimal environmental impact and waste. It aims to maximize output per unit of resource input, through design, production, and consumption improvements. The concept is central to sustainable development and the transition to a circular economy, where resources are kept in use longer, wastes are minimized, and decoupling of economic growth from resource depletion is sought.

Key dimensions include energy efficiency, material efficiency, water efficiency, and land-use efficiency. Resource productivity, defined as GDP per unit of resource use, and the material footprint, which estimates total material extraction across the life cycle, are common indicators. Life-cycle assessment and input-output analysis support evaluation across stages from raw material extraction to end-of-life.

Strategies to improve ressou rceeffektivitet include dematerialization (reducing material intensity of products), eco-design, extended producer responsibility, and process optimization in manufacturing. In construction, modular design and better insulation improve efficiency; in industry, lean production, energy management systems, and circular supply chains promote resource conservation.

Policy instruments that support resource efficiency include standards and labels, incentives for energy- and material-efficient technologies, industrial symbiosis, and reporting requirements. Barriers include data gaps, rebound effects, split incentives, and upfront costs. Measuring progress consistently remains a challenge, but advances in material flow accounting and circularity metrics provide a basis for tracking improvements over time.
