WLC-GWP

WLC-GWP calculates the GWP greenhouse gas emissions of a building over a reference study period of 50 years across the whole life cycle.

This page provides information on the methodology, European regulation, application within the Dutch system and the available documentation.

The WLC-GWP methodology follows from the obligations set out in the revised European EPBD Directive. From 2028 onwards, new buildings larger than 1,000 m² will be required to have a WLC-GWP calculation. WLC-GWP stands for Whole Life Cycle Global Warming Potential. The outcome will form part of the energy label of buildings.

This calculation combines both the material-related greenhouse gas emissions across the full life cycle of buildings and the emissions from building-related energy use during the use phase into a single indicator, including any energy exported back to the grid.

What is the difference between MPG and WLC-GWP?

The environmental performance calculation (MPG) and WLC-GWP are not the same.

The environmental performance calculation covers multiple (19) environmental impact categories of materials in buildings.
WLC-GWP focuses specifically on greenhouse gas emissions across the full life cycle of a building.

Both methodologies have a different focus and are complementary.

WLC-GWP brings together material-related and operational greenhouse gas emissions in a single calculation covering the full life cycle of buildings. Read more about the meaning of WLC-GWP, its relationship with Whole Life Carbon and the role of greenhouse gas emissions within buildings.

This section contains the official methodological documents and technical background for WLC-GWP. The Assessment Method describes how the calculation is performed and which starting points and system boundaries apply.

WLC-GWP is linked to the European EPBD IV Directive and the transition towards zero-emission buildings. These pages provide further information on the European context, the development of the methodology and the planning for WLC-GWP.

WLC-GWP affects various parties within the construction sector, from producers and data suppliers to clients, advisors and LCA professionals. Find out which developments are relevant to your organisation.
