What is a Life Cycle Assessment?
A Life Cycle Assessment (LCA) is a standardized tool that reviews the environmental impact of products throughout their entire life cycle.
It is a global analysis of the environmental burdens, directly or indirectly caused by a product, a material, a process, or even more in general, by a system.
To date, it is the most recognized method to quantify environmental impacts over the entire life cycle.
LCA from cradle to grave
Why performing LCA?
Closing cycles
Save virgin
raw materials
Avoid
emissions
and waste
INTEGRAL CHAIN MANAGEMENT
LCA shows:
where to reduce environmental burdens
where to save costs
LCA standards
European and International standards dealing with LCA in construction products:
ISO 14040 Environmental management - Life cycle assessment - Principles and framework
ISO 14044 Environmental management - Life cycle assessment - Requirements and guidelines
ISO 14020 Environmental labels and declarations - General principles for labels and declarations of products, systems and services
ISO 14025 Type III – Environmental Product Declarations
ISO 21930 is based on the ISO 14025 norm, but is more specifically related to building products
EN 15804 Sustainability of construction works - Environmental product declarations - Core rules for the product category of construction products
EN 15942 Communication format (EPD)
PEF Method 2013
PEF Guidance 2013
EN 15804
Provides core product category rules for all construction products and services.
It provides a structure to ensure that all EPD are derived, verified and presented in a harmonized way.
It is organized in modules (mandatory/optional) covering different life cycle stages.
The indicators declared in the individual information modules of a product life cycle shall not be added up in any combination of the individual information modules into a total or sub-total of the life cycle stages.
Declarations based on EN 15804 are not comparative assertions per se.
7 environment impact categories.
EN 15804 Impact categories
The Life Cycle Impact on the environment is divided into categories
What is an Environmental Product Declaration (EPD)?
The EPD provides LCA-based information to assess the environmental performance of products over their entire life cycle, from cradle to grave
EPD is a standard way of communicating the output of a life cycle assessment
Simply said, EPD is an harmonised communication format of your LCA
Can be used for different LCA standards (ISO 14040 series and EN 15804*)
* Construction products standards
PEF – Product Environmental Footprint 1
In 2013 the European Commission launched a major new initiative called:
“The Single Market for Green Products”
The rationale for this initiative was summarised by the Commission as :
PEF – Product Environmental Footprint 2
Legislative package, ‘Boosting the Single Market for Green Products’ (April 2013) Communication & Recommendation addressed to Member States and private sector to
perform LCA based analysis using PEF Method
Harmonized methodology
Applicable to all products (PEF) and Organizations (OEF – Organization Environmental Footprint)
To ensure better understanding of consumer behavior & provide better information on the environmental footprints of products, including preventing the use of misleading claims, and refining eco-labelling schemes.
Still ongoing process
Product Environmental Footprint Category Rules (PEFCRs)
Provide specific rules to calculate the environmental footprint for a certain product group, including benchmark and, if appropriate, performance grades.
Each PEFCR focuses on the most relevant life cycle stages, processes and impact categories for the product group in scope.
A declaration compliant with a PEFCR can be used to make comparisons and comparative assertions.
15 impact categories (8 more than EN 15804 ones).
PEF Impact categories
Eutrophication of freshwater: ecosystem's response to the addition of artificial or natural
substances to an aquatic system
Eutrophication marine
Freshwater ecotoxicity: how chemicals affects environment and the organisms living in it
Human toxicity - cancer effects
Human toxicity – non-cancer effects
Particulate matter/Respiratory inorganics: a.k.a. particle pollution is a complex mixture of
extremely small particles and liquid droplets
Ionising radiation – human health effects
Resource depletion: depletion of water
Land transformation
In addition to EN 15804
Example of product system life cycle
The entire cycle that goes from “cradle to grave”:
Product stage: manufacturing of all system components including transport and all processes upstream of the manufacturing stage, e.g. raw material supply or energy provision
Construction process stage: transport of the complete system to the building site/trench and installation of system (building/trench)
Use stage: operation (installed pipe
system), maintenance, repair and
replacement, including all transport
End of life stage: de-construction,
reuse, demolition, recycling and disposal
of the complete pipe system, including all
transport
