Sustainability Assessment Services (SAS)

"We help you measure and improve your environmental impact."


We want a positive impact on our global environment. We do this by helping our clients measure and improve the impact of their organisations as well as their products.

The SAS branch has over 10 years of experience providing sustainability assessments and support for a wide range of products, services and organisations: from breakdown services to biotechnology, and from concept to lab, pilot or full scale production.


We support organisations who want to improve their global impact by providing them the data they need in order to identify where they can make a difference. We also help organisations measure and compare the global impact of their products. We do both by means of Life-Cycle Assessments (LCA). These are used to evaluate entire product life-cycles: from production out of raw natural resources to use and waste treatment, including inputs, outputs and emissions of every step.

Our studies provide the following insights:

  • Get to know the total impact of your product or service. So that you know how important it is and so that you can compare it to that of alternative solutions.
  • Get to know the main causes or hotspots of the total impact. So that you understand your impact and know exactly where to focus to make a real difference.

We offer standardized and custom LCA studies for internal or public use (see below) as well as economic and social sustainability assessments and independent study reviews.

EPD: for commercial products (light version)

Environmental Product Declarations (EPDs) are standardized and widely applied LCA based sustainability assessments which can be used to evaluate the environmental impact of commercial products. EPDs are more complete than Carbon Footprints as more diverse impact categories are assessed, but they are not as extensive as the more advanced Product Environmental Footprints.

The evaluation is performed following the Product Category Rules (PCRs) published by Environdec, the international EPD system. These PCRs define the impact categories that are to be assessed for different product types as well as the structure and contents of the report. Only the most important impact categories for the matching product category are evaluated. These can include for example climate change, acidification, and eutrophication.

Local regulations sometimes require the publication of EPDs to substantiate green product claims, so they are often a good choice for the evaluation of (almost) market-ready products.

PEF/OEF: for commercial products (full option)

The product and organisation environmental footprints (PEF and OEF) are used to determine a whole range of environmental impacts, hot spots, improvement potentials, data quality and uncertainty in a standardized manner. They are executed following strict PEF and OEF guidelines published by the European Commission. The method was developed in order to harmonize environmental assessments of products, allowing easier comparison of results.

The following impact categories are taken into account:

  • Climate change (kg CO2 eq.)
  • Ozone depletion (kg CFC-11 eq.)
  • Human toxicity – cancer effects (CTUh)
  • Human toxicity – non-cancer effects (CTUh)
  • Particulate matter (kg PM2.5 eq.)
  • Ionizing radiation human health (kBq 235U eq.)
  • Ionizing radiation ecosystems (interim) (CTUe)
  • Photochemical ozone formation (kg NMVOC eq.)
  • Acidification (molc H+ eq.)
  • Terrestrial eutrophication (molc N eq.)
  • Freshwater eutrophication (kg P eq.)
  • Marine eutrophication (kg N eq.)
  • Freshwater ecotoxicity (CTUe)
  • Land use (kg C deficit)
  • Water resource depletion (m3 water eq.)
  • Mineral, fossil & renewable resource depletion (kg Sb eq.)

All PEF/OEF studies are reviewed by at least one external expert.

ISO 14040/14044 LCA: for research projects

The ISO 14040 and ISO 14044 standards are very popular LCA standards that provide a clear framework and guidelines while still allowing plenty of freedom for the LCA practicioner to focus on very specific research questions. As such they are perfect for research projects in which the assessed processes are still at conceptual, lab or pilot scale; for study subjects that are more complicated than single products or organisations; or in order to answer very specific questions.

Results can be expressed in any impact category, so in addition to those used in carbon footprint or PEF studies you can also opt for e.g. the following categories from the ReCiPe method:

  • Damage to ecosystems (species.years).
  • Damage to human health (DALY).
  • Resource depletion (US Dollar).
  • Overall environmental damage (points).

The scope can include the entire life cycle or be limited to part thereof:

  • Cradle to cradle: full life cycle with recycling.
  • Cradle to grave: full life cycle with waste disposal.
  • Cradle to gate: from raw resource extraction up to a certain point in the life cycle.
  • Gate to gate: including only a limited part of the life cycle.

All of our custom LCAs are reviewed by at least one internal or external expert.
