Summary:
In 2024, Vizcab conducted the third edition of its Low Carbon Barometer, a Europe-wide initiative aimed at capturing the state of play in Life Cycle Assessment (LCA) adoption and carbon maturity across the construction sector. With insights from over 270 professionals across 11 countries — including engineers, developers, architects, and general contractors — this Barometer serves as a compass for the industry's decarbonization efforts.
Life Cycle Assessment is increasingly recognized as a cornerstone methodology to measure and manage the environmental impact of buildings. However, its adoption remains uneven across Europe, influenced by regulatory maturity, professional training, and local market dynamics.
This Country Focus article explores how Germany is navigating the LCA transition, highlighting how professionals are adopting LCA practices, what specific drivers and barriers they face, and how their progress compares to the broader European context. Through this lens, we aim to provide actionable insights for professionals working in and with Germany helping them better align with current trends, anticipate regulatory shifts, and embrace low-carbon construction as a new standard.
National Regulations:
No mandatory national regulation for LCA in buildings, but specific standards exist for public buildings under the BNB (Bewertungssystem Nachhaltiges Bauen). BNB is a sustainability assessment system for public buildings, covering the entire lifecycle (design, construction, operation, and demolition). It is based on international standards (EN ISO 14040, EN ISO 14044, DIN EN 15978) and uses the ÖKOBAUDAT database for construction materials to calculate environmental impacts (energy, GHG, water, etc.). BNB is mandatory for new federal buildings and major renovations.
Thresholds:
No national limit values for carbon emissions of buildings over their lifecycle. However, regions can adopt stricter local requirements (example : Baden-Württemberg)
Financial Incentives:
A special €500 billion climate fund, with €100 billion allocated to low-carbon construction and sustainable infrastructure.
Loans and grants from the public bank KfW for energy-efficient renovations, with incentive levels based on energy efficiency standards (KfW 55, 70, etc.).
Mandates:
No national mandate for LCA in private buildings, but discussions are ongoing to integrate LCA into future regulations, aligned with European directives (notably the Energy Performance of Buildings Directive - EPBD). These discussions focus on setting performance limits for buildings' environmental impact, especially in terms of greenhouse gas emissions over their lifecycle.
Influence of EU frameworks (EPBD, CSRD, EU Taxonomy) : Stricter energy performance requirements for buildings due to the EPBD, with potential future integration of Life Cycle Assessment (LCA). These requirements apply uniformly to all EU member states, including Germany.
Enhanced sustainability reporting obligations for large companies in the construction sector, driven by the CSRD. These transparency obligations apply across all European countries, with no specific differences for Germany.However, it is important to note that the implementation of the CSRD has been delayed due to the Omnibus Directive, which postpones the application of certain regulatory requirements. This delay affects the timeline for compliance but does not change the scope of the obligations once they come into force.
Access to sustainable finance (green loans, green bonds) for projects that align with EU Taxonomy criteria, promoting LCA and low-carbon construction. These taxonomy criteria are consistently applied across the European Union.
Overall, the influence of EU frameworks is pushing Germany, like all other EU member states, towards a more sustainable construction sector, with greater transparency, accountability, and a strong focus on lifecycle environmental impacts.

Some respondents did not provide an answer (50%). Among those who did:
On average, respondents spent approximately 5.1 days this year to complete a Life Cycle Assessment (LCA).
Among respondents who provided an answer:
Although Germany has resources such as the ÖKOBAUDAT database and the DGNB certification system, challenges remain in integrating practical and accessible LCA tools into day-to-day workflows. Ensuring the availability of tools aligned with European regulatory frameworks—such as the EU Taxonomy—is also a priority.
Professionals are seeking to improve the reliability of their carbon strategies. About 29% of respondents indicated that ensuring the credibility of their project’s carbon strategies is a key challenge. Standardizing calculation methods and aligning with European requirements (such as EPBD 2028 and CSRD) are essential for improving the consistency and impact of LCAs.
To support widespread adoption of LCA in Germany, it is crucial to build professional capacity through targeted training, high-performance tools like Vizcab Platform, and consistent methodologies, all while ensuring alignment with European policy frameworks.
The insights gathered through the Low Carbon Barometer 2024 are clear: the adoption of Life Cycle Assessment (LCA) across Europe is no longer a niche practice but a fundamental shift in how the industry measures impact and builds for the future. In Germany, this transition is unfolding at its own pace, shaped by local regulations, market maturity, and professional engagement.
To meet the carbon thresholds of 2025 and beyond, and to align with the broader goals of the European Green Deal, all actors must accelerate their efforts. This means not only improving technical tools but also increasing awareness, harmonizing data, and investing in training.
