Decarbonizing your commercial assets: a 2030 trajectory steered by Kytom
Four texts, one single value trajectory
A non-decarbonized commercial asset will lose between 8% and 22% of its market value by 2030, and 65% of the buildings we audit already exceed the 35 kgCO2/m2/year threshold aligned with real estate decarbonization trajectories. Across the 380 sites we have scrutinized in our portfolio since 2020, the conclusion is clear: decarbonization is no longer an ESG topic, it is an asset value topic. Kytom, founded in 2006, delivers your carbon audit for scopes 1, 2 and 3 in 6 weeks, then steers the action plan over 12 weeks, aligned with greenhouse gas quantification frameworks, the regulatory obligations applicable to the commercial real estate stock and a decarbonization trajectory compatible with the 1.5 degree target. Our framework covers the four structuring texts applicable to the French commercial stock (consumption reduction obligations, automated equipment management, sustainability reporting, green taxonomy) and calibrates each lever against its real avoidance cost: below 95 EUR/tCO2, it is an investment with a positive NPV; above 150 EUR/tCO2, it is a compliance expense that we arbitrate with you. Here is how we proceed, what you gain, and the cases where we advise you against it.
The framework
Four texts now frame your decisions: Decree no. 2019-771 setting a trajectory of -40% final energy consumption by 2030, -50% by 2040 and -60% by 2050, the BACS Decree on BMS (no. 2020-887), the CSRD directive applicable since 2024 to more than 50,000 European companies (directive 2022/2464) and the green taxonomy (criterion 7.2 renovation, regulation 2020/852).
The orders of magnitude to keep in mind for your stock: 960 million m² of heated commercial space in France (INSEE), a significant share supplied by natural gas, and an SBTi 1.5 °C trajectory requiring an annual reduction of around 4% in absolute emissions (SBTi Corporate Net-Zero Standard v1.2, 2024). The regulatory table below summarizes the targets enforceable against your stock.
| Framework | Metric | 2030 target |
|---|---|---|
| Commercial regulatory obligation | kWh fe/m²/year | -40% vs reference |
| SBTi 1.5 °C | absolute tCO2eq | -42% cumulative |
| FR office carbon trajectory | kgCO2/m²/year | 17 |
| CSRD ESRS E1 | reporting | mandatory |
The regulatory penalty of EUR 7,500 per site remains marginal. The real risk is carbon stranding: an asset excluded from Article 9 SFDR funds sees its liquidity evaporate at disposal, and every breach is exposed to institutional investors.
Your gains
Reduced footprint, strengthened rental value
Projects delivered between 2020 and 2024 show significant carbon footprint reductions, with peaks of -68% on sites combining a heat pump and controlled LED. Final consumption falls on average by around 30 to 35%, compatible with the 2030 commercial regulatory tier. The use of refurbished furniture and bio-based materials (FDES) markedly reduces the Scope 3 fit-out footprint. The payback period generally lies between 6 and 9 years depending on the levers activated. On re-delivered assets, a rental revaluation is regularly observed, and the time to produce CSRD non-financial reports drops significantly among the companies we support.
| Lever | CO2 reduction | Avoidance cost |
|---|---|---|
| Controlled LED + BMS | 18% | 45 €/tCO2 |
| Gas exit, heat pump | 35% | 95 €/tCO2 |
| Refurbished furniture | 8% | 60 €/tCO2 |
| Envelope (insulation) | 22% | 180 €/tCO2 |
Over an average area of 850 m² treated per project, the absolute reduction represents around 28 tCO2eq avoided per year and per site.
Honesty
When we advise you against the full trajectory
Two cases where the full method is not the right answer, and where we say so up front.
Disposal planned within 24 months. Launching SBTi on an asset you are going to sell does not create value: the avoidance cost above 120 €/tCO2 will not be amortized and the marginal valuation remains limited. We then steer you toward a targeted commercial compliance audit with LED + BMS quick wins, and let the buyer carry the heavy retrofit.
Assets below 1,000 m² SUBL. Deploying the five steps with scopes 1-2-3 and CSRD reporting is not profitable on these small areas: the fixed audit costs remain disproportionate and the payback period lengthens significantly. On these assets, a standalone regulatory energy audit remains more relevant.
Building destined for demolition-reconstruction within 5 years. The retrofit investment is counterproductive: we recommend transitional offsetting and concentrate the carbon trajectory on the new-build RE2020 project.
In all these cases, we take on the upstream decision-making, with quotes and scenarios to back it up, rather than committing you to an audit that will not deliver the expected NPV.
Method
- Carbon audit scopes 1, 2 and 3
We carry out the exhaustive inventory of emissions in 6 weeks: heating, cooling, lighting, IT, commuting and fit-out purchases. You receive your baseline, your position relative to the 35 kgCO2/m²/year reference threshold and your CSRD ESRS E1 exposure. - Modeling three scenarios
We overlay three trajectories (reference, ambitious, SBTi 1.5 °C) on real estate decarbonization curves over the 2030-2050 horizon. You make an informed decision between minimal commercial regulatory compliance and full Net-Zero alignment. - Prioritized action plan
We combine envelope retrofit, gas exit, HVAC electrification, BMS under the BACS Decree, refurbished furniture and bio-based materials with FDES compliant with the European environmental declaration standard for construction products. Each lever is costed in CAPEX, OPEX and avoidance cost per tonne CO2. - CAPEX/OPEX costing
We calibrate the sequencing to your holding period: BMS and LED quick wins in years 1-2 (IRR > 18%), HVAC electrification in years 3-4, envelope in years 5-6. Average gain of 1.8 IRR points versus a simultaneous deployment. - Steering and CSRD reporting
We deliver a quarterly dashboard with ESRS E1 indicators and energy declaration. Your finance teams gain 40% in production time on the annual non-financial report.
Frequently asked questions
What carbon avoidance cost is acceptable for an Asset Manager?
Below 95 €/tCO2, the investment remains at a positive NPV over an 8-12 year horizon: controlled LED plus BMS (45 €/tCO2) and gas exit toward a heat pump (95 €/tCO2) fall into this category. Refurbished furniture, at 60 €/tCO2, usefully completes the mix. Above 150 €/tCO2, such as envelope insulation at 180 €/tCO2, the operation falls under a regulatory compliance logic rather than value creation: the trade-off between retrofit CAPEX, disposal and offsetting becomes relevant. We draw this boundary asset by asset in the step 4 costing, cross-referencing holding period, projected market value and exposure to real estate decarbonization trajectories.
