CO2 Performance ladder
Renewi uses a CO2-management system according to the CO2-Performance ladder level 4 and is certified for this. In this way we provide better insight, clear reduction targets, communication and participation in the value chain and contribute to a more sustainable society. The CO2-Performance Ladder is an instrument to stimulate companies to reduce GHG emissions consciously in its own business operations and in its value chain. The instrument involves energy saving, efficient materials use and the use of sustainable energy sources. The CO2-Performance Ladder is managed by the Foundation for Climate-Friendly Procurement & Entrepreneurship (SKAO). The information and documents below demonstrate this method.
The ambition of Renewi is in line with the global objectives of the CO2 PL: to not exceed the 1.5˚C warming of the planet, as described by the Paris Climate Agreement. Renewi has committed to:
- Reduce 42% of its Scope 1 and 2 by 2030 (FY31) compared to base year FY22
- Reduce 25% of its Scope 3 by 2030 (FY31) compared to base year FY23
All under absolute contraction approach, from the base year being the recalculated FY22 and FY23, respectively. These targets are in line with the guidance of the Science-Based Targets initiative.
Based on this commitment, a detailed project planning for individual carbon reduction projects has been developed and is continuously being improved. The general plans include:
- The decrease of fossil fuel consumption (via electrification) of our fleet
- Energy sobriety & efficiency measures throughout our operations
- Installation of renewable energy production & storage capacity (PV/wind/storage)
- Adapting our processes where possible in order to reduce our process emissions
- Futher optimizing processes on site,
- Carbon capture & storage/utilisation
A more detailed description of the performance, management system, and planned actions can be found in the management reports:
Renewi follows the operational control rule in determining its GHG accounting boundary. For FY25, the CO2 Performance Ladder boundary has been updated based on the organisational chart dated July 2025, following the divestment of the Municipal business. All Group services now only support the business units that previously fell within the scope of the CO2 Performance Ladder (Renewi Netherlands Holding B.V. and Renewi NV). As a result, these are no longer excluded from the GHG accounting boundary.
Because the boundary now covers the full operational scope of the Group, excluding only entities without operational activities or those outside the Group after divestment, the accounts presented here no longer differ from the Group’s operational GHG boundary. Historical figures for FY22, FY23 and FY24 have been restated to include Group overheads and exclude our Municipal business for consistency and comparability.
The historical figures for FY22-24 have been restated to reflect the updated organisational boundary aligned with Renewi Europe B.V. and excluding the divested Municipal business. Under this new boundary, the baseline Scope 1 and 2 emissions for FY22 amount to 528,900 tCO2e, followed by 509,219 tCO2e in FY23 and 488,355 tCO2e in FY24. This represents a consistent downward trajectory, averaging approximately 4% reduction per year over the three-year period.
Between FY22 and FY23, emissions decreased by a total of 19,681 tCO2e. The reduction was primarily driven by lower processed tonnages, resulting in lower process emissions, alongside reductions in diesel use across the fleet and upgrades to landfill-gas capture systems further contributed to lower emissions. The expansion of GreenCollective also supported reductions through fewer kilometres driven and improved logistics efficiency.
Results from FY24 showed a continuation of this downward trend, with emissions further decreasing to 488,355 tCO2e. The main contributor of this reduction was on the energy side, with the proportion of renewable energy increasing from 39% to 52%. In addition, the fleet was expanded with eight new electric vehicles. Renewi also continued to explore an increased role for biofuels within the fuel mix. Process emissions from composting and other biological treatment activities declined in line with reduced incoming tonnages.
Together, these developments reinforce the consistent downward trajectory observed since FY22 and demonstrate the combined effect of the application of certificates of origin, fleet modernisation, optimisation of operational processes and continuous improvements at site level.
Insight into the CO2 footprint FY25
Results for FY25 show that Renewi continues to make progress in reducing its CO2 footprint. Total Scope 1 and 2 emissions decreased further to 460,924 tCO2maintaining a steady downward trend since the FY22 baseline. These results reflect both structural improvements, the maturing of ongoing decarbonisation initiatives, and a lower overall throughput.
The year-on-year reduction is driven by a number of factors. Firstly, FY25 saw a significant increase in renewable electricity coverage across our sites, rising from 52% to 70%. By then end of FY25, electricity consumption at all Belgian Commercial Waste sites was fully covered with green certificates, and coverage at Dutch Commercial Waste sites had reached 99.6%. At the same time, we continued the gradual shift towards cleaner fuels in our fleet and operations through the slow but steady adaptation of HVO and other biofuel alternatives, combined with a reduction in natural gas consumption in favour of electricity. Process-related emissions also fell, partly due to the natural decline in methane emissions from landfills and partly due to the impact of the Green Gas project at CWNL.
A decrease in processed output also contributed to the overall reduction in direct emissions and fuel use. Together, these developments support the ongoing downward trend in total emissions and demonstrate steady progress towards Renewi’s near-term decarbonisation objectives.

Contracts with award advantage
In FY25, the Commercial Waste Netherlands division has 9 contracts in which the CO2 Performance Ladder certificate was an important requirement. 1 of those was newly secured in FY25, with the CO2PL advantage as favourable, although not decisive criterion. Remaining 8 are the projects continued from the years past. Total carbon footprint of those projects per year is estimated to not exceed 5% of total carbon footprint of the division.
In Belgium, no CO2PL advantage contracts were won since Belgium was included in the certificate boundary in FY23.
Progress mid-year FY26
Due to our end-year data being audited to limited assurance level, the mid-year results are not published in full to maintain the same quality standards. A high-level directional brief is expected in December 2025.

Development projects in the value chain
We strive to be the leading waste-to-product company, and as such, we collaborate with partners and customers up and down the value chain to make the most impactful materials innovation happen.
Two of these projects have been presented on SKAO website as development projects and chain initiatives
- Renewi Nordsol and Shell focus on BioLNG
- Renewi, IKEA and Return mattress open fourth mattress recycling plant
- Renewi and PreZero continue to focus on Green Collective
Chain analyses
Renewi is aware of the influence of the company in the different chains, up and downstream, in which it acts. Based on this knowledge, Renewi identifies promising possible energy and CO2-reduction measures in the chains, and potential chain partners for tackling them. For two projects with chain partners, so-called chain analyses were carried out and the possible CO2-identified emission savings in the chain. Summaries of these two projects are available:
