"How do I know if it is really green"

What our clients tell us.

You will recognise your situation if…

  • You receive product sheets with no EPD or verifiable ecolabel.
  • Your ESG committee demands evidence but the budget remains tight.
  • Suppliers announce "green" solutions with no precise quantified data.
  • You are torn between several competing environmental standards with no clear benchmark to decide.

Issues and impacts

Hidden cost

Unlabelled furniture often has to be replaced within 5 to 7 years, compared with 12 to 15 years for a certified Vitra or Herman Miller seat. Over 850 sqm, the cumulative additional cost reaches 60,000 to 90,000 euros excl. VAT, not counting end-of-life waste reprocessing fees.

Human risk

VOCs (volatile organic compounds) emitted by unlabelled paints, adhesives and panels degrade indoor air quality. The INRS points out that 15 to 20% of open-space complaints concern headaches and irritations. An A+ ecolabel or EMICODE EC1 reduces these emissions by 80%.

Reputational risk

Since 2023, the CSRD directive has required mid-sized companies with more than 250 employees to produce verified non-financial reporting. Fitting out without EPDs or traceability exposes you to a greenwashing risk penalised by the DGCCRF, with fines of up to 300,000 euros and mandatory publication of the conviction.

How Kytom does it

Since 2006, Kytom has integrated environmental criteria from the programming phase, never as an afterthought. For each work package, our space planners require an EPD (Environmental and Health Declaration Sheet) filed in the INIES database, a recognised ecolabel (NF Environnement, Blue Angel, EU Ecolabel) or a Cradle to Cradle certification. Across the 1,200+ projects delivered, we systematically measure the carbon footprint of the selected materials and propose three quantified scenarios to the client: market reference, intermediate and low carbon. Traceability covers 100% of structuring work packages (partitions, flooring, furniture, acoustics). This method secures executive management teams committed to an environmental certification trajectory in operation, in line with their regulatory obligations to reduce consumption in the tertiary sector.

Our method

  1. 1. Diagnose

    Audit of existing materials, calculation of the possible reuse rate (target 20 to 30%) and mapping of high-carbon-impact work packages. Deliverable: environmental criticality matrix per item, validated with your ESG officer and quantified in kg CO2 equivalent per sqm.

  2. 2. Frame

    Definition of minimum thresholds per family: mandatory EPD for partitions and flooring, ecolabel for paints and textiles, 100% PEFC or FSC wood. Deliverable: environmental specifications enforceable on suppliers, integrated into the tender documents and verified at each call for tenders.

  3. 3. Design

    Three scenarios compared on cost, carbon and lead time, with a preference for French and European manufacturers. Deliverable: quantified decision note presented to the steering committee, including an environmental simulation and a furniture reuse commitment of at least 25%.

  4. 4. Deliver

    Acceptance control package by package with verification of effective technical sheets and ecolabels. Deliverable: environmental traceability file archived for 10 years, usable for CSRD reporting and environmental management system audits. Post-delivery measurement of indoor air quality.

Cost and ROI

Sustainable materials extra cost
+8 to +15% vs standard
Gap measured over 850 sqm between the reference scenario and the certified low-carbon scenario.
Project lead time
12 weeks on average
Lead time preserved thanks to early sourcing from the materials programming phase.
Environmental ROI
3 to 4 year payback
Through doubled furniture lifespan and energy savings linked to the tertiary sector regulations, which require a reduction in final energy consumption of at least 50% by 2040 compared with 2010.

Frequently asked questions

What is an EPD and why require it?

An EPD (Environmental and Health Declaration Sheet) is a standardised document filed in the INIES database. It quantifies the product's carbon impact across 11 indicators. Without an EPD, no environmental simulation is defensible in an audit.

Which ecolabels should you really recognise?

Favour Type I ecolabels verified by an independent third party: NF Environnement, EU Ecolabel, Blue Angel, Cradle to Cradle. Be wary of supplier self-declarations with no certificate or number that can be verified with the certifying body.

Is furniture reuse reliable?

Yes, provided you go through a structured player (social economy organisation or REP-PMCB scheme) with a minimum 2-year warranty. Reuse divides the carbon footprint by 6 and reduces the furniture budget by 30 to 50% on eligible items.

BREEAM, LEED or another standard: which certification should you choose? For the record, version v4.1 BD+C is based on the ASHRAE 90.1-2016 standard, assessed on cost and GHG emissions.

Several standards certify the building and its fit-out, with an approach centred on environmental performance and quality of use. Other international standards target occupant well-being more specifically. For a stand-alone tertiary fit-out project, the standards dedicated to Fit-Out or to sustainable building operation remain the most relevant.

What budget extra cost should you anticipate?

Between +8 and +15% on the materials and furniture envelope for a certified low-carbon scenario. Over 850 sqm at 1,200 euros excl. VAT/sqm, the extra cost represents 80,000 to 150,000 euros, paid back in 3 to 4 years through extended lifespan.

How do you avoid supplier greenwashing?

Require three proofs per package: an EPD filed in INIES, a Type I ecolabel with a certificate number, and a technical sheet stating the percentage of recycled content. Any undocumented "eco-responsible" claim must be excluded from the tender documents.
