EPD for the GLT LED TUBE – verified sustainability with substance
Published October 20th, 2025
What is an Environmental Product Declaration (EPD)?
An Environmental Product Declaration (EPD) is a standardised, verified environmental declaration for a product. It provides transparent and comparable data on the environmental impacts generated throughout the entire lifecycle – from manufacturing to end-of-life. The data is independently and scientifically verified, in Germany by the Institut Bauen und Umwelt e.V.
👉 An EPD answers the key question:
How sustainable is this product in measurable and verifiable terms?
What Exactly Does an EPD Include?
- The international standards ISO 14025 and EN 15804-A2
- The underlying data is based on a Life Cycle Assessment (LCA) covering the entire product lifecycle.
This assessment includes:
👉 Raw materials → production → transport → use → disposal/recycling
Why EPDs are indispensable in the construction and real estate sector
The construction and real estate sector is under increasing regulatory and societal pressure to provide transparent evidence of the environmental impacts of products. Public authorities, investors and companies require reliable environmental data for products that are used for decades.
EPDs are now relevant for:
✅ Sustainable construction and refurbishment projects
✅ Public procurement and tenders
✅ ESG (Environmental-Social-Governance) and CSRD (Corporate Sustainability Reporting Directive)-reporting
✅ Long-term investment decisions
Unlike generic sustainability claims, EPDs provide an objective, data-based foundation. They are the established standard for comparability and transparency.
An EPD is:
✅ fact-based
✅ comparable
✅ independently and scientifically verified
(Institut Bauen und Umwelt e.V.)
An EPD is not:
❌ an eco-label
❌ a manufacturer’s self-declaration
❌ a simplified CO₂ figure
What benefits do EPDs offer?
EPDs provide certainty – for planning, procurement and investment decisions. They replace assumptions with verifiable data and offer clear advantages.
Procurement and planners
Construction products can be compared on an objective data basis. This reduces risk, increases planning reliability and protects against greenwashing.
Companies and manufacturers
EPDs enable credible positioning within ESG strategies and support tendering processes, CSRD reporting and structured sustainability communication.
Buildings and investors
Robust environmental product data enables the measurable improvement and assessment of a building’s life cycle performance. This strengthens the long-term value of the property.
Life Cycle Assessment as the foundation of every EPD
The Life Cycle Assessment (LCA) is the scientific basis of every EPD. It considers all relevant phases of a product over its entire service life (cradle to grave).
Life cycle phases assessed:
Standardisation of this methodology ensures comparability, audit security and long-term traceability of the data.
The importance of EPDs for green building and certifications
EPDs are a key data source for sustainable building certifications and are directly incorporated into the assessment of construction products. EPDs are recognised by national and international rating systems, including:
- DGNB (Deutsche Gesellschaft für nachhaltiges Bauen).
- BNB (Bewertungssystem nachhaltiges Bauen des Bundes).
- LEED (Leadership in Energy and Environmental Design).
- BREEAM (Building Research Establishment Environmental Assessment Method).
Especially in public tenders, municipal projects and international institutional investments, EPDs are increasingly a prerequisite.
EPDs from the perspective of German LED Tech
German LED Tech deliberately focuses on transparency instead of marketing promises. Sustainability is understood as a measurable product quality, not a buzzword.
Lighting is a long-term factor in a building’s environmental footprint. Energy consumption, service life, material use and replacement cycles have an impact over many years. This is precisely why a sound, data-based assessment is essential.
The EPD for the GLT LED TUBE at a glance
A scientifically verified Environmental Product Declaration is available for the GLT LED TUBE. It documents the environmental impacts of the pro-
duct over its entire life cycle. The EPD has been verified by the
Institut Bauen und Umwelt e. V.Institut Bauen und Umwelt e. V. and is publicly available – as a data sheet and in digital form. It can be directly integrated into all building certification schemes as well as ESG- and CSRD-reporting:
Key aspects of the GLT LED TUBE EPD:
✅ Long service life (130.000 hours)
✅ High energy efficiency during operation
✅ Production location Germany
✅ Defined material composition
✅ Repairability- and Recyclability
Added value of the GLT EPD for B2B, municipalities and ESG strategies
The Environmental Product Declaration (EPD) of the GLT LED TUBE can be directly integrated into ESG and CSRD reporting. It supports sustainable refurbishment projects and meets the requirements of public procurement procedures and current building regulations.
Procurement professionals and planners can easily compare the life cycle assessments of construction products and identify the most sustainable solution.
EPD – a key contribution to:
- Achieving climate targets
- Reduced energy and maintenance costs
- Long-term economic efficiency
- Attractive and healthy working environments
Conclusion – EPD as a strategic standard
Environmental Product Declarations are not an optional add-on, but a prerequisite for future-proof products, sustainable buildings and credible ESG strategies.
German LED Tech stands for sustainability that is verifiable, comparable and relevant in the long term – documented, independently verified and transparent.
Glossary
* EPD: Environmental Product Declaration
An Environmental Product Declaration (EPD) is a standardised and independently verified environmental product declaration for construction products, based on international standards ISO 14025 and EN 15804-A2.
An EPD provides transparent and comparable information on the environmental impacts of a product across its entire life cycle – from manufacturing through to disposal. The data is scientifically validated and independently verified; in Germany, this is carried out by the Institut Bauen und Umwelt e.V.
* ESG Policy: Environmental, Social and Governance
The ESG framework defines criteria and guidelines established by the United Nations (UN) and financial institutions for integrating environmental, sustainability and social considerations into corporate governance, as well as within public authorities, governments and institutions.
* CSRD Directive: Corporate Sustainability Reporting Directive
The Corporate Sustainability Reporting Directive (CSRD) is an EU regulation mandating standardised sustainability reporting for companies across Europe. It has applied since 2024 to large companies meeting at least one of the following criteria:
- more than 250 employees
- balance sheet total exceeding €25 million
- annual turnover exceeding €50 million
From 2026 onwards, publicly listed small and medium-sized enterprises (SMEs) will also be required to comply.
