My 2022 EPD Numbers Infographic now available

The latest update of my infographic on construction product EPD Numbers is now available at

EN 15804 EPD numbers are still contining to increase and are now over 12,000, over half available digitally. Taking account of construction product EPD to ISO 21930, there are now over 80,000 EPD, mainly due to over 60,000 digital EPD for concretes to ISO 21930 available in the North American market via the EC3 tool.

When is an EPD not an EPD #2

In a follow on from my previous post, I had been thinking of highlighting two documents which looked like EPD. One claimed that verification was optional for Environmental Product Declarations (EPD) for business to business communication, and the other said it was “awaiting verification”.

Luckily both seem to have disappeared from the internet, and hopefully are being independently verified before being published in an EPD programme.

For all types of products, verification of EPD is a requirement of ISO 14025, the EPD standard, and thus of EN 15804, the European standard for EPD for construction products. Verification needs to be undertaken by an independent expert – they need to be an expert in Life Cycle Assessment, and also of the product group in question, and they need to be independent.

ISO 14025 states, “Independent verifiers, whether internal or external to the organization, shall not have been involved in the execution of the LCA or the development of the declaration, and shall not have conflicts of interests resulting from their position in the organization.”

Why is verification essential? Verification is the check that the standards have been followed. This means that verifiers check, for example, that:

  • the data provided by the manufacturer is plausible – are there enough inputs to make the outputs, can they explain why their product has a much lower or higher impact than others for example
  • the LCI data used is of suitable quality and representative
  • allocation to co-products and by-products is sensible
  • the modelling and calculations have been done correctly
  • the right characterisation factors have been used, and
  • the EPD provides all the information that is required in the standard.

Where EPD have been produced by pre-verified EPD tools, it is still be necessary for the EPD to be verified. For example, the checks on plausibility of the data entered into the tool and that inputs have been linked with the right LCA datasets in the tool still need to be done by an independent verifier.

If an EPD to EN 15804 has been been verified, then the EPD is required to include a table which looks like this one below. It must state whether an internal or external verification has taken place, and it is good practice to name the verifier, although this is only essential if the EPD is aimed at consumers rather than architects and specifiers. If it doesn’t state whether internal or external verification has been undertaken, then you need to check if the EPD has actually been verified, otherwise it isn’t compliant with the standard.

All EPD also have to give the date of issue and period of validity – this is normally 5 years from issue. If the EPD doesn’t state when it was published or how long is it valid for, then it is not compliant with the standard and is not an EPD to EN 15804.

If you are not sure about an EPD, contact the manufacturer or EPD provider and ask if it complies with the standards and has been verified. Let me know if you find documents which look like EPD but don’t seem to comply.

ASBP publish a comprehensive list of EPD for UK produced construction products in our new Briefing Paper

I’m really pleased that as part of the series of EPD Briefing Papers I’ve been writing with the ASBP, I’ve been able to compile a new online Briefing Paper which lists all the EPD for UK produced construction products with links.

Finding EPD for UK produced products has been difficult for specifiers and those assessing embodied carbon, with the EPD spread across numerous EPD Programmes – this paper brings them together and with over 350 EPD, I believe it is comprehensive. They are mainly manufacturer specific EPD, but there are a number of sector EPD for the UK covering brick, concrete and timber, and I have also included a list of European Sector EPD.

If you are aware of other EPD, please contact me to let me add them. We are looking to update the Briefing Paper regularly so it remains a current listing.

The other ASBP EPD Briefing Papers provide an introduction to EPD, How to Use EPD and Where to find EPD in general. If you are interested in finding out more about EPD and how to read and use them, I will be running a Webinar with ASBP – Understanding EPD on 22nd April.

UK Government has required Whole Life Carbon assessments, which means embodied carbon assessments, for all new public works projects and programmes since December 2020

In October 2020, the Government responded to the Committee on Climate Change’s 2020 Progress Report which had recommended to Government, in relation to embodied carbon in buildings, that the Government, “support the assessment and benchmarking of whole-life carbon in buildings.” The Government responded by saying, “The Government does not currently assess or benchmark the embodied carbon of buildings. To assess the embodied carbon of buildings a simple, standardised method of calculation would be required, supported by a robust evidence base.”

Yet two months later, in December 2020, UK Government has required, through the Construction Playbook, that central government should adopt the use of whole life carbon assessments for all public works projects and programmes, including building, civil engineering, construction and equipment projects. This is mandatory on a ‘comply or explain’ basis for all contracting authorities within central government departments (such as the Ministry of Defence), and its arm’s length bodies such as their agencies (e.g. the Highways Agency, Environment Agency, Homes England, HM Prisons and HM Courts), and public bodies, and this will be enforced through spending controls. The wider public sector is also encouraged to take account of the Construction Playbook. A list of all the bodies affected is provided here.

The playbook requires that:

  • “All contracting authorities should set out strategies and plans for achieving net zero GHG emissions by or ahead of 2050 for their entire estate/infrastructure portfolio. These should be aligned under an overarching sustainability framework, and systems and processes should be in place to ensure their projects and programmes deliver on the targets set.”
  • “Recognising the design life of public works, contracting authorities should adopt the use of whole life carbon assessments to understand and minimise the GHG emissions footprint of projects and programmes throughout their lifecycle.”
  • “Contracting authorities should require that solutions put forward by potential suppliers are accompanied by a whole life carbon assessment. This should be conducted in collaboration with the wider supply chain, reflecting ways of minimising the GHG emissions across the life of the asset.”
  • Whole life carbon assessments are expected to mature over time with higher-level assessments at the early engagement phase developing into robust assessments included in the final tender documentation.”

For central government, compliance to the Construction Playbook is being driven through departments’ governance processes, central Cabinet Office controls (projects over £10 million per transaction) and the Treasury Approvals Process. The Cabinet Office Sourcing Programme will work with in-scope organisations to embed the Construction Playbook within local governance forums and approval processes.

Whole Life Carbon is described in the RICS Professional Statement for Whole Life Carbon Assessment for the Built Environment, as the operational carbon and embodied carbon emissions over a project’s expected life cycle. So by requiring Whole Life Carbon assessments, the Government are requiring Embodied Carbon assessments. The RICS Professional Statement on Whole Life Carbon is aligned to EN 15978, though only measuring carbon, and provides the default methodology for whole life carbon assessment in the UK, endorsed by the RIBA, CIBSE, IStructE and many other organisations. It has also been used as the basis of the Greater London Authority’s requirement of embodied carbon assessment and reporting for all referable schemes as part of the New London Plan.

#RegulateEmbodiedCarbon – ACAN’s campaign

Architects Climate Action (ACAN) launched their campaign to regulate embodied carbon in the UK this evening with over 300 people online! France, the Netherlands, Germany, Finland and Sweden have all got Embodied Carbon regulation in place, or require assessment of public buildings. The UK shouldn’t be able to leave 10-15% of its Greenhouse Gas Emissions unregulated when it has less than 30 years to reduce our carbon emissions to zero.

Three take away actions

1 Read ACAN’s report

2 Sign ACAN’s petition and

3 Send a copy of ACAN’s report to your MP, and ask them why we aren’t looking to regulate in this area.

More than 10,000 EN 15804 EPD at the start of 2021!

At the start of January 2021, there are just over 10,000 Verified Environmental Product Declarations (EPD) to EN 15804 for construction products registered globally, as shown in my 2021 Infographic.

Regulation in France, where the RE2020 Building LCA legislation will come into force in the summer, and environmental claims can only be made about construction products which are supported by EPD, means that the French EPD programme now has the largest number of EN 15804 EPD, known there as FDES, with the French inies programme which also lists PEP EcoPassport (EPD for building services equipment), now having over 30% of all EN 15804 EPD. (In the Infographic numbers, I’ve not included the données par defaut from the inies database which are generic data for products, rather than EPD)

This year, there are new programmes in the Infographic: EPD Belge, and VUPS in the Czech Republic. There has also been big growth in the number of EN 15804 EPD in the SCS programme in the US, and in the programmes in Finland and the Netherlands. The International EPD has also seen good growth in the number of EPD through its hubs in Australasia, Latin America and Brazil and Asia.

In addition, use of concrete EPD generators in the United States means there are now over 36,000 EPD for concrete there, mostly using ISO 21930. This is driven, in part, by initiatives such as that in Portland, Oregon, for all concrete used in City construction projects to have an EPD. The state of Oregon has also provided a free concrete EPD tool and financial reimbursements for concrete companies. For more information about regulation on embodied carbon, EPD and LCA around the world, see this review of city policies and this of policy and regulation more generally.

You can find the full infographic at, and if you want to find EPD, check out the Briefing Paper that I wrote for the Alliance for Sustainable Building.

When is an EPD not an EPD?

Signify and Philips (its lighting brand) are talking a good talk about EPD on their website. The article is is called, “How Environmental Product Declarations are helping green the lighting industry“.

They talk about why people might want EPD, for example:

“One way companies can affirm their sustainability efforts is by issuing Environmental Product Declarations (EPDs) for the items they manufactureor, on the procurement side, requesting them from manufacturers.” 

 “Indeed, the EPD has become an internationally accepted way of assessing and communicating environmental impact in B2B interactions.”

“A growing trend is evident in the lighting business: End-users, like municipalities launching public street-lighting projects and private real estate companies installing lighting in their buildings, have increasingly started requesting Life-Cycle Assessment Studies and EPDs.”

And they recognise what an EPD is, a VERIFIED declaration, as they say,

“An EPD is essentially a verified version of what’s known as a Life-Cycle Assessment (LCA) of the product—a document that analyzes the product’s lifetime environmental impacts.”

And they recognise that there are EPD programmes, like the EcoPassport programme in France,

“National and international associations and programs, like France’s EcoPassport system for related technologies like heating, electricity, and lighting, are also boosting awareness of EPDs.”

And they tell us that they have published some EPD,

“To provide information on material compositions and environmental impact, we at Signify have published a number of EPDs for different LED luminaires in our professional indoor and outdoor portfolios. Please read the EPDs for our Maxos fusion trunking system and feel free to reach out to us with questions.”

The only problem, they don’t have an EPD. You can check it at Click to access 142476_BROCHURE_Maxos-fusion_EPD_A4_LR_3Dec.pdf

The actual document says “Environmental Product Declaration of the Maxos fusion
Circular Economy Ready luminaire (ISO 14021, based on ISO 14040/14044, EN 15804)

So it says it’s an EPD, but ISO 14021 is the standard for self-declared claims. It also says,

“The CEN Norm EN 15804 serves as the core PCR”

but if so, you’d expect to see some environmental indicator results for the product – but this document only shows you a graph showing the breakdown of impacts over the life cycle, with each impact adding up to 100%. So no information on the actual impacts. The declaration has also not been verified by an independent expert as is required for an EPD to ISO 14025 or EN 15804.

In my view, this is purposely trying to mislead people by suggesting Signify and Philips have EPD when they most definitely don’t.

Eco Platform news

Eco Platform is the association for European EPD Programme Operators using EN 15804. The Eco Platform website has just had a revamp, coinciding with the launch of their digital EPD Eco Portal, where you can search for digital EPD by product type and country. The EPD use the InData format, a harmonised way of providing EPD data which follows the International Life Cycle Database (ILCD) format, with extra fields relevant to EPD (known as ILCD+EPD!). The next step will be providing API so that tools can link directly with the database.

So far only some of the EPD Programme members have included their digital EPD, and not all of their EPD are available digitally, but it is a great step forward, and Eco Platform programme operators have agreed to add all their new EPD to the Portal in future, so this will become a growing resource. For the time being, ECO EPD as pdfs are still available at the original Eco Platform EPD Registry.

I’m also pleased to see as part of the revamp, the archive of Eco Platform Newsletters are now all available. I’ve been pleased to contribute to a number of them, for example:

05/2020: Article on the ways EPD are being used in Regulation

Q4 2019: Article on the use of EPD in Green Procurement

Q2 2019: Article on the value of EPD

Happy reading and EPD searching!

Over 7000 EN 15804 Environmental Product Declarations (EPD) were available at the start of 2020 with numbers continuing to increase

Rather late in the year I am adding my 2020 EPD Infographic to my blog which provides the numbers of EPD at the start of the year. The number of EN 15804 EPD have continued to rise, with French FDES overtaking German IBU EPD in terms of numbers. When you add in the French PEPEcoPassport – the EPD for building services equipment which follow EN 15804 principles then the French Inies database is the largest database for EPD. It also includes many “données par defaut” – default generic data to be used in the absence of EPD.

The full infographic can be found at

In addition to these EN 15804 EPD, there are now literally thousands of EPD to ISO 21930 available in North America – mostly from the concrete industry which has so far provided over 32,000 individual EPD for different concrete mixes at different plant. The easiest way to find these is to use the EC3 website which allows you to search by location, compressive strength, curing time, slump, % of Supplementary Cementitious Material, even to find products with an Embodied Carbon (A1-A3) within a certain range.

If you are looking for EPD or generic LCA data for construction products, then my Briefing Paper for the Alliance for Sustainable Building, “Environmental Product Declarations (EPD) – Where to find them” is a great place to start, providing links to all the existing EPD programmes and databases around the world (that I’m aware of – please let me know if you find others).
