Introduction
The Construction Products Regulation (CPR), which entered in force in 2011, specifies the need to
address the sustainable use of natural resources in harmonised product standards (Basic Works
Requirement 7 or BWR 7). The current Mandate M/124 and accepted replies do not address the CPR,
therefore it is still not clear how in practice to address BWR 7 in product standards.
Once part of a Standardization Request (SReq), environmental sustainability assessment of bituminous
binders needs to be addressed in the revision of the product standards for harmonisation. This raises the
question of the need for drafting a CEN/TC 336 specific document giving guidelines on how to address
sustainability in the product standards and how, in practical, to realize the corresponding assessments
for bitumens and bituminous binders.
Work is ongoing in several CEN/TCs, either on horizontal level or per respective product groups. The
information presented in this document was collected by the members of the task group environmental
sustainability of the CEN/TC 336 at the time of drafting of this document, December 2023, and should
therefore not be considered as exhaustive.
1 Scope
This document provides an overview of:
— current requirements in the European Union and in individual European states to address
sustainability in the field of construction works where bitumens and bituminous binders are used;
— the requirements of the Construction Products Regulation (CPR) on environmental sustainability
and analyses the implications for bitumens and bituminous binders;
— existing horizontal standard EN 15804:2012+A2:2019 related to core rules for the product category
of construction products and assesses if it can be used without any additional documents for bitumen
and bituminous binders;
— status of draft standards developed for specific complementary product category rules by
CEN/TC 154, CEN/TC 227, CEN/TC 254 and any other relevant TCs, and assesses if these drafts could
require any additional documents specific for bitumens and bituminous binders;
— other relevant documents.
This document is intended to provide support to CEN/TC 336 for assessing the need for any further
standardization documents covering specific product category rules for bitumens and bituminous
binders or for other standardization documents in the field of environmental sustainability of bituminous
binders.
This document covers bitumens and bituminous binders as described in EN 12597, including cut-back
and fluxed bituminous binder, and bitumen emulsion, as used in construction works.

5 Status of environmental requirements in the European Union and individual
European states
Some countries in Europe have already implemented environmental requirements for construction and
more specifically for asphalt materials, including certification system. The Scandinavian countries have
been pioneers in developing EPD systems in accordance with EN 15804 since 2017. France has developed
a system and data base for construction with FDES ("Fiche de Déclaration Environnementale et
Sanitaire" — environmental health and safety data sheet) based on EN 15804 since 2014. The
Netherlands also set up a system and database used for civil works since 2017 with first product category
rules published in 2019. Other countries have initiated initiatives over the last few years to set up rules
and environmental requirements for construction project either at the design stage or for construction
works.
Annexes A and B provide an overview of current systems and initiatives at the date of this document.
6 CEN activities and standards
6.1 EN 15804
EN 15804:2012+A2:2019 is a European Standard providing the framework to define product category
rules (PCR) in order to establish type III Environmental Declarations in accordance with
EN ISO 14025:2010 [1] for goods and services in the construction sector. Regulations established by each
member state need to be in accordance with that standard.
If developed, Environmental Product Declarations (EPD) have to be established based on relevant PCR
for construction works with respect to life cycles stages. In accordance with EN 15804:2012+A2:2019 ,
all construction products and materials shall declare modules A1-A3 — product stage, C1-C4 — end of
life stage and D – beyond the system boundaries, with some specific exemptions. Other modules A4-A5 —
construction process stage and B1-B7 — use stage may be optional depending on the type of EPD.
The points potentially relevant for bitumens and bituminous binders are:
— the material will stay embedded in final product, either asphalt mix or waterproofing, and is not
separated at end of the life. Consequently, the exemption to cradle to gate (A1-A3), as stated
in EN 15804:2012+A2:2019 , subclause 5.2 may be applied unless the material contains biogenic
carbon. For any product containing biogenic carbon the declaration of modules C1-C4, end of life and
module D beyond the life cycle cannot be omitted;
— when EPD is limited to A1-A3 modules, there is no need to define a functional unit, however, a
declared unit, typically tons, needs to be defined;
— EN 15804:2012+A2:2019 states that specific data or average data should be used. An EPD
describing an average product shall be calculated using representative average data of the products.
An EPD describing a specific product shall be calculated using specific data.
EN 15804:2012+A2:2019 , Table 1, suggests generic or specific data for raw materials. Generic data
may be used for processes the producer cannot influence e.g. commodities, raw material extraction,
electricity production. The data used must be as recent as possible and must be representative of a
reference year, within 10 years for generic data and 5 years for producer specific data.
There are several tables contained in EN 15804:2012+A2:2019 that list environmental impact indicators
as shown in Table 1.
Table 1 — List of tables in EN 15804:2012+A2:2019 listing environmental impact indicators
Table Type of indicator Number of indicators
3 Core environmental indicators 13
4 Additional environmental indicators 7
6 Resource use 10
7 Waste information 3
8 Output flows 4
9 Biogenic carbon content 2
Total indicators 40
For the construction, use and end of the life stages, other indicators are defined.
The following two categories of additional information not derived from the life cycle assessment (LCA)
shall be addressed:
— technical information describing the technical and functional performance over the life cycle stages
of the final construction including underlying scenarios;
— additional information on emissions to indoor air, soil and water during the use stage describing the
release of dangerous substances not covered by LCA.
The validity of EPD is in accordance with EN ISO 14025:2010 [1], unless there are reasonable changes of
±10 %, which may require an update of the EPD. A 5-year period is included in
EN 15804:2012+A2:2019 , 7.1 as general information to declare.
6.2 CEN/TC 154 – Aggregates
CEN/TC 154 (aggregates)/WG 13 is drafting c-PCR with two draft Technical Reports at the preliminary
stage (PWI adopted on 2021-02-15): PWI 00154207 [2] and PWI 00154209 [3]. At the time of
publication of this document, these drafts have not yet been made available and WG 13 is still collecting
comments.
The Technical Reports provide core product category rules for type III environmental declaration of
natural, manufactured and recycled aggregates for building and civil engineering according to
EN 17555-1 [9], EN 13383-1 [8] and EN 13450 [7]. The TRs define the parameters to be reported, what
EPD types (and life cycle stages) to be covered, what rules to be followed in order to generate life cycle
inventories (LCI) and conduct life cycle impact assessment (LCIA) and the data quality to be used in the
development of EPDs.
In addition to the common parts of EN 15804:2012+A2:2019 , the Technical Reports:
— define the system boundaries;
— define the modelling and assessment of material-specific characteristics;
— define allocation procedures for multi-output processes along the production chain;
— include the rules for calculating the LCI and the LCIA underlying the EPD;
— provide guidance for the determination of the reference service life (RSL);
— give guidance on the establishment of default scenarios.
6.3 CEN/TC 227 – Road materials
In 2017-2018 CEN/TC 227 prepared the draft standard prEN 17392-1 [4] which defines core product
category rules for asphalt pavement materials. This draft complied with EN 15804:2012+A1:2013, in
force at this time, and covered the production stage A1 to A3. This draft was intended to be submitted for
CEN Enquiry in January 2019 but was postponed waiting the revision and approval of the
EN 15804:2012+A2:2019. Making mandatory the declaration of modules A1-A3, C1-C4 and D with
modules A4-A5 and B1-B7 being optional. prEN 17392-1 was modified accordingly and sent for CEN
th th
Enquiry from March 19 till June 11 2020. It came with 60 pages of comments with majority of votes
rejecting the draft.
In October 2020, after analysing the outcomes of the CEN Enquiry, it was decided to restart the project
as a CEN Technical Specification and simplify the document as much as possible. The scope has been
simplified to limit to the mandatory modules in accordance with EN 15804:2012+A2:2019 (i.e. A1-A3,
C1-C4 and D) plus the optional modules A4-A5. Optional modules B1-B7 have been left out of the Scope
to begin with. The reference unit to use is the declared unit “metric tonne of bituminous mixture”. An
internal review process with CEN/TC 227/WG 1 experts was undertaken at the end of 2021. The group
after having deeply re-worked the document as a CEN/TS requested CEN/TC 227 for the registration of
a New Work Item which was approved and the NWI was registered in the CEN active work programme
on 2024-10-01 as WI 00227561.
During the drafting process, some key issues were discussed:
— the allocation of impacts associated with the use of reclaimed asphalt (RA) depends on the end-of-
waste criteria and this depends on each country (sometimes even on the region);
— it is not possible to assume that the impacts of RA at the end-of-life will be zero because 100 % of the
mix will be re-used. Thus, the definition of scenarios is required;
— these scenarios cannot contain specific values or assumptions, such as transport distances or fuel
consumption. This is to be done at a national level;
— it is difficult to declare the benefits of using sustainable solutions, such as warm mix asphalt or low-
rolling-resistance mixes;
— if Modules B1-B7 were to be included, it would be extremely difficult to estimate the required
Reference Service Life. The durability depends not only on the quality but also on external factors,
such as climate conditions, traffic, maintenance investment, etc.
6.4 CEN/TC 254 – Flexible sheets for water proofing
CEN/TC 254 (waterproofing) has drafted two European standards: EN 17388-1 [5] and EN 17388-2 [6].
These projects adopted in July 2022 (on 2022-07-07) are based on previous versions (WI 00254182 and
WI 00254183), approved at the second CEN Enquiry on 2021-04-08 but with a lot of comments, leading
to a cancellation.
The projects have been restarted (WI 00254189 and WI 00254190) and have been approved at CEN
st
Enquiries in September 2022. The draft standards were finalised in the 1 quarter of 2023, submitted to
nd
Formal Vote in the 2 quarter of 2023 and approved by CEN/TC 254. However, after review by
CEN/TC 350, some inconsistencies with EN 15804:2012+A2:2019 have been identified resulting in the
freeze of the publication process. Following the implementation of the comments, the final drafts have
been approved after a second formal vote and have been published.
6.5 CEN/TC 350 – Sustainability of construction works
CEN/TC 350 is responsible for the development of horizontal standardised methods for the assessment
of the sustainability aspects of new and existing construction works (buildings and civil engineering
works) in the context of the UN Sustainable Development Goals and of the circular economy. The
standards describe coherent methodologies for the assessment of sustainability of construction works
covering the assessment of environmental, social and economic performance (aspect and impacts) of
buildings and civil engineering works, and the provision of construction product environmental
information (EPD).
The committee is entrusted with an advisory function to CEN committees to ensure the effective
implementation of horizontal core rules regarding the development a specific PCR based on
EN 15804:2012+A2:2019 .
Upon its start CEN/TC 350 was driven by two horizontal mandates from the European Commission:
mandate M/350 (for a common language and approach, i.e. a harmonized methodology with core
indicators, between all stakeholders in the building sector) and mandate M/366 (for developing
horizontal test standards for the release of regulated dangerous substances from construction products
into soil, ground water, surface water and indoor air under normal conditions of use). Recently the
Commission issued a third one, related to climate change: mandate M/480 (on the energy performance
of buildings). Construction products are in a maelstrom: a plethora of policy initiatives are ongoing since
the launch of the Green Deal; the economic world is changing and globalisation is increasingly under
pressure. The transition towards decarbonisation is now full on the agenda. As the Mandate M350 is
coming to an end, CEN/TC 350 will have to look forward and reflect upon how he can contribute to
sustainability and to the construction sector.
With this regard, CEN/TC 350 launched an internal enquiry as regard to the future. The feedback received
was analysed, together with the group of convenors. Based on that outcome, the CEN/TC 350 drafted a
road map. Among this road map six priorities have been put forward as both urgent and important:
1. c-PCR: CEN/TC 350 is the reliable and professional partner of the European Commission in assessing
compliance of c-PCR with EN 15804:2012+A2:2019 and – if wanted and deemed acceptable – the
Commission’s needs. It puts in place the necessary processes, structures, and reference documents
to do this and assists product TCs.
2. CCUS (Carbon Capture, Utilization and Storage) and avoided emissions: WG 3 develops a project of
standardization document to deal with the different aspects of CCSU and avoided emissions in EPD.
3. Circular economy with Sub-Committee 1.
4. Readability: Establish a mechanism to safeguard clear and understandable language when writing
standards for them to become more accessible and user friendly
5. EU Taxonomy: Develop a Technical Report with guidance on how to implement the EU taxonomy for
sustainable construction.
6. Digitalisation: Establish a standardised full digital workflow of the sustainability assessment of
construction works. Put in place a structure allowing collaboration between the different ISO and
CEN committees involved.
Some of the priorities are in progress, while others have not yet started. For those not started, it will still
be up to CEN/TC 350 to decide whether or not they decide to complete them. This is a list of identified
themes, objectives and possible future actions, not as a list of decided actions. As CEN/TC 350 depends
on volunteers, the prioritisation of the actions will depend largely on the identification of finding
leaderships.
Regarding the CPR Acquis, the thematic subgroup on Environmental sustainability of construction
products started at the beginning of October 2022. Only the horizontal CEN/TC 350 has been invited to
appoint experts as the thematic subgroup will only deal with horizontal matters and not product specific.
One key objective of this subgroup is to define the essential characteristics that will be part of the
Standardization Requests in the sector of the construction products.
As per timeline, milestones A, B, and C were completed:
— Milestone A.1: a recommended list of essential characteristics related to Life Cycle Assessment (LCA)
environmental impact indicators for all construction products. Other tasks of milestone A deal with
other indicators (see below). The baseline of the proposed LCA indicators is Annex I (Part A, point 2)
of the legal proposal for the new CPR. The approach used in EN 15804:2012+A2:2019 is the
reference used to define the list of LCA environmental impact indicators.
— Milestone A.2-5: recommended list of essential characteristics related to resource use, waste, output
flows and biogenic carbon. These essential characteristics complement the life cycle assessment
(LCA) essential characteristics addressed in Milestone A.1 (SGEnv_Mil.A.1) and are based in the same
life cycle inventory (LCI). Milestone A.2-5 is based on the identified technical and regulatory needs
by Member States and at European level. The approach used in EN 15804:2012+A2:2019 is the
reference method used to define these indicators.
— Milestone B: recommended methodology for the assessment of the essential characteristics related
to environmental sustainability based on life cycle assessment (LCA) (see Milestone A.1) and the
complementary essential characteristics related to resource use, waste, output flows and biogenic
carbon (see Milestone A 2-5). Milestone B is based on the identified technical and regulatory needs
at Member State and European level. The baseline of this proposal is EN 15804:2012+A2:2019 .
— Milestone C: delegated act amending Annex V to Regulation (EU) No 305/2011 as regards the
assessment and verification of constancy of performance (AVCP) of construction products and on the
applicable systems to assess and verify constancy of performance of construction products,
regarding the essential characteristics of environmental sustainability. This delegated act was also
presented to the CPR steering group and to the Advisory Group on Construction Products.
7 CPR requirements regarding Environmental Sustainability
7.1 CPR 2011 (Regulation No. 305/2011)
According to the CPR (3.1), Article 3, the essential characteristics of construction products, such as
bitumen and bituminous binders, shall be laid down in harmonised technical specifications in relation to
the basic requirements of the construction works. CPR 2011, Annex I lists the basic requirements for
construction works (BWR) and in particular part 7
— “Construction works as a whole and in their separate parts must be fit for their intended use, taking into
account in particular the health and safety of persons involved throughout the life cycle of the works.
Subject to normal maintenance, construction works must satisfy these basic requirements for
construction works for an economically reasonable working life.”
— "Sustainable use of natural resources. The construction works must be designed, built, and demolished
in such a way that the use of natural resources is sustainable and in particular ensure the following:
— reuse or recyclability of the construction works, their materials and parts after demolition;
— durability of the construction works;
— use of environmentally compatible raw and secondary materials in the construction works."
The current applicable mandate M/124, covering road construction products including bitumen and
issued by the European Commission in 1998, is however not based on Regulation No. 305/2011 but on
the previously applicable Council Directive No. 089/106/EEC.
Directive No. 89/106/EEC did not include BWR 7 and consequently Mandate M/124 does not require
essential characteristics related to that basic work requirement for bitumen for road construction and
surface treatment of roads. Consequently, current harmonised standards do not address essential
characteristics related to BWR 7 and producers cannot address them in their declarations of
performance.
7.2 Draft from March 2022 for the revision of the CPR
In March 2022, the European Commission published a draft revision of the CPR, which completed review
by the European Council and the European Parliament in December 2023.
Key part of the draft is the integration of the European Green Deal and the Digital Transfer. This includes
a list of general sustainability requirements, which are stated to be further defined per product family in
Commission acts/harmonised standards.
In this draft revision of the CPR:
— Article 22 provides “Additional environmental obligations of manufacturers”.
— Article 47 widens the tasks for Notified Bodies to verify environmental sustainability undertaken by
the manufacturer of the construction product.
— Annex I “Requirements” in Part A: Basic requirements for construction works and essential
characteristics to be covered lists basic requirements for construction works including “sustainable
use of natural resources of construction works” throughout their life cycle.
— Annex II “Declaration of Performance and of Conformity” includes sustainability characteristics.
— Annex V Assessment and verification systems (AVS) is verification of environmental sustainability.
— Annex VI covers “essential characteristics for which a reference to a relevant harmonised technical
specification is not required in the context of notification of notified bodies”.
8 Conclusions
Since the Construction Products Regulation (CPR) entered in force in 2011, it is compulsory to address
sustainable use of natural resources in the harmonized product standards however it is still very unclear
how to address it in practice in product standards related to bituminous binders.
EN 15804:2012+A2:2019 gives a framework for product category rules for construction products but
may not be precise enough for bituminous binder producers to establish Environmental Product
Declarations on a consistent and consequently comparative manner.
Many initiatives are being taken at national level for some construction products in order to better
establish common rules necessary to ensure comparable data in particular in the context of tenders.
Several CEN Technical Committees working on construction products and in particular CEN/TC 227
working on bituminous mixtures, CEN/TC 254 working on waterproofing membranes (including
bituminous membranes) and CEN/TC 154 working on aggregates have already undertaken or finalized
the drafting of standardization documents to establish more precise and dedicated complementary
product category rules.
If specific product category rules were to be established in standardization documents, the question of
which modules to consider in particular in regards to the exemptions mentioned in
EN 15804:2012+A2:2019 can be raised.
