A standardized document providing information about a product's environmental impact, based on an LCA.

Criteria used to evaluate a company's operations and sustainability performance, including its environmental impact, social responsibility, and governance practices.

Specific, detailed information directly related to the product being assessed. Primary, foreground data is supplier-specific whereas secondary data refers to industry-specific default values.

In LCA, the quantified performance of a product system for use as a reference unit in a life cycle assessment study. It can be 1 kg, 1 m3 or 1 product.

A measure used to compare the ability of different greenhouse gases to trap heat in the atmosphere. It represents the total warming effect of one unit of a gas over a fixed period, often 100 years, compared to one unit of carbon dioxide (CO2).

Emissions of gases that trap heat in the atmosphere, contributing to global warming and climate change.

A widely used international accounting tool and standard for government and business leaders to understand, quantify, and manage greenhouse gas emissions.

International standards providing guidelines and principles for conducting and reporting life cycle assessment studies.

A database providing information on the environmental impact of materials, often used in LCA.

A systematic analysis of the environmental aspects and potential impacts associated with a product throughout its life cycle.

An approach for assessing the total cost of ownership, considering all costs associated with the life cycle of a product.

A phase in LCA where potential environmental impacts are assessed using inventory data.

A phase in LCA involving the compilation of detailed inputs and outputs across various stages of a product's life cycle.

An index developed by the McArthur Foundation to evaluate the circularity aspects of material flows of a product, from raw materials to end-of-life.

In manufacturing, the percentage of material that is wasted during the production process.

An international treaty adopted in 2015 to limit global warming to well below 2 degrees Celsius, preferably to 1.5 degrees, compared to pre-industrial levels.

Supplier- or company-specific foreground or background data. Examples include primary information about a product's weight or a PCF for a certain material.

An EU initiative that quantifies the environmental performance of a product or service throughout its life cycle.

The stages a product goes through from raw material extraction to disposal or recycling.

A strategic approach to managing the lifecycle of a product from inception, through engineering design and manufacture, to service and disposal.
