Validated by RISE
CO2e calculation for reuse, validated by RISE
Choosing reused furniture from Soeco by Yllw genuinely reduces climate impact. For every item we source, refurbish and resell, we calculate the avoided CO2e compared with an equivalent newly manufactured product. Our methodology has been reviewed and validated by RISE Research Institutes of Sweden.
Independent validation
RISE confirms that our methodology is scientifically robust and suitable for communicating environmental benefits.
Substitution principle
Each refurbished item replaces the need for a functionally equivalent new product.
Traceable reporting
We present savings per item, per project, and as a total summary for the delivery.

How we calculate
1. Define the comparison product
For every reused furniture item, we determine a functionally equivalent new product to compare against.
2. Use relevant sources
We start from Environmental Product Declarations and complement them with quality-assured emission factors from research and industry data.
3. Calculate avoided emissions
The CO2e saving equals the emissions linked to new production minus emissions related to reuse such as inspection, refurbishment and spare parts. Transport and operation are considered marginal in this context and are included where they affect the result.
4. Report at multiple levels
We show results per item, per project and as a total summary, providing clear follow-up and decision support.
What RISE has validated
Scientific basis
The methodology is grounded in established scientific principles.
Clear substitution
A refurbished item replaces a functionally equivalent new product.
Relevant assumptions
Assumptions regarding functional equivalence, transport, operation and the use of EPDs are justified and in line with practice.
Sources aligned with research
Emission factors are consistent with research, industry data and Scandinavian sources.
Frameworks and standards
The frameworks and standards we rely on to make calculations comparable, traceable, and easy to communicate.
ISO 14040 and 14044
Life-cycle perspective and clear system boundaries for traceable calculations.
WBCSD Guidance
Guidance for calculating and reporting avoided emissions.
Avoided Emissions Framework
Supports a methodology that enables comparability and credible communication.
