The LCBI certification scheme will highlight exemplary low carbon buildings.
The Low Carbon Building Initiative (LCBI) has launched the first pan-European methodology for whole life-cycle carbon measurement of buildings, with set limit values, aiming to cut the buildings’ carbon footprint by half.
The real estate sector, responsible for nearly 39% of global CO2 emissions1 , is crucial in the battle against global warming. To meet the 2050 carbon neutrality goal, European countries must reduce the carbon footprint of all buildings—new, retrofitted, and in-use.
Initial efforts focused on lowering energy use in existing buildings and transitioning to carbon-free energy. However, accurately measuring carbon emissions at every life-cycle stage—production, construction, operation, and demolition—is essential for a comprehensive climate impact assessment of buildings.
To date, a unified European method to understand and compare building carbon footprints has been lacking. Addressing this, the LCBI has developed a unique methodology to measure building carbon footprints across their entire lifecycle, with limit values, basis of a certification scheme for low-carbon buildings. This method aligns with major European standards and tools (Taxonomy, Level(s), CRREM, RICS).
Publicly available on LCBI website, this unified European methodology simplifies the quantification and comparison of building carbon footprints, fostering decarbonization across Europe.
Launched in 2022 by major players in the European real estate sector alongside the Association Bâtiment Bas Carbone (BBCA, established in 2015), LCBI first focuses on newbuilt: offices, residential, and hotels. Its broader objective is to encompass all real estate categories, targeting new, retrofit and in-use buildings.
Arnaud Regout, President of LCBI Advisory Committee, Chief Investment Officer BPI Real Estate: “Commitment of LCBI stakeholders was key to build this innovative tool, now accessible to entire real-estate sector in Europe. As the first pan European low-carbon methodology, LCBI will facilitate performance benchmarking of carbon footprints for all.
“Such harmonization will provide a powerful signal to the market and help to unlock further private sector investment in low carbon buildings.”
LCBI method and limit values:
basis for a certification scheme highlighting low carbon buildings
Considering the entire life cycle, the LCBI certification scheme assesses building’s performance on three indicators:
– embodied carbon (emissions of building elements) measured in kgCO2e/m² over 50 years
– operational carbon (based on energy consumption and sources) measured in kgCO2e/m²/year
– biogenic carbon stored (use of bio-based materials) in the building measured in kg CO2e/m²
To define access to the 3 levels of the label (Standard, Performance, Excellent), each of those indicators are rated on two criteria:
– Completeness of the Life Cycle Analysis
– Achievement of carbon emission thresholds
This innovative matrix rating fosters transparency and allows to compare buildings carbon footprints.
LCBI certification scheme is a means to position life-cycle carbon footprint at the core of real-estate players strategy. It offers them multiple benefits:
– For project owners, it functions as a low-carbon design tool, and a means to highlight exemplary low-carbon buildings.
– For investors, LCBI provides access to consistent and reliable data on the whole life-cycle carbon footprint of buildings, serving as reliable indicator for investment.
Bureau Veritas is set to be the first auditor for the LCBI certification scheme. Project owners interested in obtaining it should contact the certifier directly. The certification process includes two stages: a provisional certificate is issued during the design phase, and the final certification is awarded upon the completion of construction works.
