A circular economy is a model of production and consumption that aims to eliminate waste and pollution by keeping materials and products in use for as long as possible. This is achieved through practices like sharing, reusing, repairing, refurbishing, and recycling. The EU aspires to fully implement a circular economy by 2050.
Circular design strategies concentrate on both the initial material sourcing (cradle) and the product’s end-of-life phase (grave) within its lifecycle. They prefer recycled materials over primary raw materials. The end-of-life stage is delayed through component repairs and reuse. Ultimately, material recycling is facilitated through take-back initiatives and single-material components, with modular design serving as key measures.
Corporate Social Responsibility (CSR) refers to a company's commitment to operate in an ethical, sustainable, and socially responsible manner. It involves actions that go beyond profit-making to address social, environmental, and economic impacts. CSR activities may include reducing environmental footprints, supporting local communities, ensuring fair labor practices, and promoting ethical business standards. Ultimately, CSR aims to create positive value for society while aligning with the company's long-term goals and reputation.
Corporate social responsibility directive (CSRD) refers to the self-regulated efforts of businesses to contribute to societal goals and ethical practices. It involves companies voluntarily integrating environmental, social, and ethical concerns into their operations and interactions with stakeholders. It is closely related to environmental, social, and governance (ESG) considerations.
Downcycling is the process of recycling materials into new products of lower quality or reduced functionality than the original item. Instead of reprocessing the material to create new products of the same type, downcycling results in products that are often less durable or less valuable. A common example is the recycling of PET bottles. Rather than turning them back into new plastic bottles, they are often downcycled into items like fleece jackets, park benches, or composite lumber. These new products typically cannot be easily recycled back into the original material, limiting their future recycling potential.
The EN15804+A2, based on ISO 14044 and ISO 14025, is one of the most important sustainability standards for creating EPDs in the construction sector in the European Union. In the Netherlands, the Nationale Milieudatabase (NMD, engl: national environmental database) further specifies this standard in its “Bepalingsmethode Milieuprestatie Bouwwerken” (BMB, engl.: Environmental Performance Assessment Method for Construction Works), which serves as the basis for ECI/MKI calculations.
EU Green Deal The EU Green Deal is a policy package to make the EU carbon neutral by 2050. Immense funds of about 1 trillion euros are available for it. Its promises range from decoupling economic growth from resource use, over nature restoration, to improved public health and well-being.
The European Ecodesign Directive (Directive 2009/125/EC), along with its counterpart, the Energy Labeling Regulation (2017/1369), establishes ecological criteria for designing and enhancing the energy efficiency of the most energy-intensive and greenhouse gas-emitting products across European Union member states.
Eco-labeling is a system that uses labels to indicate that a product meets specific environmental standards, making it easier for consumers to identify sustainable and environmentally-friendly options. This process is voluntary and typically involves three different types of labels:
Type I: A third-party certification where an independent organization verifies that a product meets specific environmental criteria.
Type II: Self-declared environmental claims made by the manufacturer or supplier, without independent verification.
Type III: An environmental declaration based on detailed information, often quantified and verified, such as an Environmental Product Declaration (EPD). This type provides transparent data on the environmental impact of a product over its entire lifecycle.
By using eco-labels, consumers can make more informed choices, supporting sustainability and reducing their environmental footprint.
ESPR The Ecodesign for Sustainable Products Regulation (ESPR) was proposed in 2022 as part of the EU Green Deal. Preparations are underway for ESPR to supersede the existing EU Ecodesign Directive. Compared to the current Ecodesign Directive, it will pose a wider range of ecodesign criteria for a wider product range and introduce a digital product passport for all regulated products. This regulation is part of the EU Green Deal.
Ecoinvent is the world’s leading LCI database containing over 18,000 unique datasets. These datasets cover a wide array of products, services, and processes, from building materials to food, and from resource extraction to waste management. Ecoinvent is the largest, most consistent, and most transparent database on the market.
The Environmental Cost Indicator (ECI, or in Dutch: Milieukosten indicator) is a single-score indicator expressed in Euro. It unites the LCA results of all impact categories into a single score of environmental costs, representing the environmental externalities of a product or project. It is based on EN15804+A2, and used in the Dutch construction industry to determine the winning bids in public tenders.
LCA results present as impact data in several impact categories. There are about 15 impact categories (depending on the LCIA method), because, for example, climate impacts and water footprints can’t be compared directly (just like apples and pears). Different LCIA methods define different impact categories.
EPD Environmental Product Declarations (EPDs) are standardized, verified documents that transparently present a product’s impact data. They are based on an LCA, adhere to strict regulations and standards (e.g. product category rules), and are generally valid for five years.
A Green Supply Chain refers to the integration of environmentally sustainable practices into the management of a product's supply chain. This approach aims to reduce the environmental impact of the entire supply chain, from raw material sourcing to production, transportation, and distribution, all the way to the product's end-of-life disposal or recycling.
Key aspects of a green supply chain include:
A green supply chain helps businesses reduce their environmental footprint while often improving efficiency, cutting costs, and enhancing their reputation with environmentally-conscious consumers.
GHG Greenhouse gas (GHG) emissions cause climate change. Much sustainability reporting focuses on GHGs because climate change could have catastrophic outcomes for humanity. A widely used GHG reporting scheme is the GHG protocol. Guiding corporations on how to measure and report their climate impacts, it also provides a product carbon footprint standard.
ISO (International Organization for Standardization) standards are internationally agreed documents. The family of ISO 14000 ff sets standards for many aspects of the measurement, management, and communication of a company’s environmental impacts. The methodology of an LCA is defined in ISO 14040 and further specified in ISO14044; all LCA standards from other organizations build upon ISO14040 & -44.
Impact data is the result of an LCA. It entails all emissions of substances into the environment, resource depletion, land- and water-use associated with a product or process. This data is contained in LCI-databases. This data is further transformed into environmental impact category scores, which are another form of impact data and represent the main LCA results.
LCIA database Life Cycle Inventory (LCI) databases offer crucial secondary impact information for conducting Life Cycle Assessments (LCAs). LCI datasets, sourced from these databases, precisely indicate the environmental impacts attributed to a product or process. This facilitates faster execution of LCAs. The most frequently utilized database is Ecoinvent.
LCIA method The process of translating raw emission data into environmental impact categories is known as the Life Cycle Impact Assessment (LCIA) method. Various LCIA methods, such as the environmental footprint (EF) method, ReCiPé, and CML 2001, have been developed by different organizations, each tailored to specific research and geographical contexts. These methods vary in terms of characterization factors and impact categories. LCA guidelines frequently recommend the adoption of a particular LCIA method.
LEED Certification (Leadership in Energy and Environmental Design) is a globally recognized system for rating the sustainability and environmental performance of buildings. Developed by the U.S. Green Building Council (USGBC), LEED certification provides a framework for identifying and implementing practical, measurable green building design, construction, operations, and maintenance solutions.
Buildings are awarded LEED certification based on performance in several key areas:
Buildings can earn different levels of certification (Certified, Silver, Gold, or Platinum) depending on the number of points they score across these categories. LEED certification helps to demonstrate a building’s commitment to environmental sustainability, and can also result in operational cost savings, enhanced occupant well-being, and an improved market reputation.
LCA Life Cycle Assessment (LCA) is a scientific methodology used to evaluate the potential environmental impacts of a product, service, or technology throughout its entire life cycle. ISO 14040 outlines the 4 phases of LCA as:
1. Goal and Scope definition
2. Inventory Analysis
3. Impact Assessment
4. Interpretation of results.
What is a Life Cycle Assessment (LCA)? LCA measures the environmental impact of a product through every phase of its life – from production to waste (or recycling, etc.). But LCA isn’t simple – there are countless factors involved:
Life cycle models (scope) Life cycle models, such as Cradle-to-grave, Cradle-to-gate, and Cradle-to-cradle conceptualize which life cycle stages are included in an LCA – they define an LCA’s scope. The five life cycle stages are raw material extraction (cradle), manufacturing, transportation, product use, and end-of-life disposal (grave).
A Product Carbon Footprint (PCF) quantifies the GHG emissions associated with a product throughout its life cycle. While all Life Cycle Assessment (LCA) standards provide PCF data alongside other impact metrics, there are also specialized PCF standards like ISO 14067, GHG Protocol Product Standard, PAS 2050, and the Pathfinder Framework.
PCR Product Category Rules (PCRs) are sets of specific rules, requirements, or guidelines for conducting LCAs or creating EPDs for a particular product category. Consistent methodologies help to compare impact data among products within a category. PCRs are developed by entities such as the EU for the PEF and by program operators for EPDs.
The Product Environmental Footprint (PEF) is a LCA guideline established by the European Commission to standardize LCA methodologies across various product categories. It introduces its own LCIA method, known as the environmental footprint (EF) method, and an open-access LCI database. The PEF methodology, including the development of PCRs, is currently underway, and therefore the utilization of PEF is not currently obligatory under any EU legislation.
The data used in LCA is sometimes uncertain, for example, we need to estimate the amount of material inputs or could use alternative datasets. Sensitivity analysis shows you the effect of data variations on your LCA results. If the data variation changes your LCA results by more than 5%, it’s crucial to get this input data right. If not, an approximation is acceptable.
