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.

Our goals

The ambition of Renewi is in line with the global objectives: to not exceed the 1.5*C warming of the planet. Renewi has committed to:

  • reduce 15% of its Scope 1 and 2 by 2025 (FY26),
  • reduce 50% of its Scope 1 and 2 by 2030 (FY31),
  • 25% reduction on Scope 3
    – all under absolute contraction approach, from the baseline year being the recalculated FY22. We consider these targets in line with the guidance of the Science-Based Targets Initiative although they have not been verified by SBTI yet.

Based on this new commitment, a detailed project planning for individual carbon reduction initiatives is under way. The general plans include:

  • the decrease of fuel use and electrification of fleet,
  • energy efficiency,
  • energy sobriety,
  • PV/wind/storage installation,
  • Futher optimizing processes on site,
  • Carbon capture.

A more detailed description of the performance, management system and planned actions can be found in the management reports:

Boundary adjustment vs the Corporate Reporting

Renewi follows the operational control rule in determining its GHG accounting boundary. The boundary of Renewi Netherlands Holding has been determined on the basis of the organization chart of Renewi in March 2024. Group Central Services are excluded from the below analysis as these activities support all legal entities, not just those that are being audited under CO2Prestatieladder. In due course of the suppliers analysis (A/C analysis) as prescribed by SKAO, we have identified that the Belgian business of Renewi, under Renewi NV entity, should be included in the CO2 Performance Ladder boundary going forward. This is reflected since the FY23 totals and going forward.

As a result of the activity above, the accounts given on this page for the purpose of CO2 Prestatieladder differ from the accounts presented in the Annual Report and the difference amounts to the operations of UK Municipal and the Group overheads.

Insight into the CO2 footprint FY22- FY23

In FY24, a miscalculation in the base year was discovered, which triggered a revalidation of the limited assurance for the years FY22 and FY23 and a change in the numbers reported. The revalidated FY22 and FY23 figures, appropriated to the boundary described above, are presented below.

Renewi Netherlands Holding has restated the baseline emissions to 527,660 tons CO2e in FY22 (market-based). In FY23, the emissions dropped to 507,391 tons CO2e.

The total CO2e footprint for 2023 (excl. Scope 3) consisted of 93% scope 1 emissions and 7% scope 2 emissions. The decrease between 2022 and 2023 can be attributed to a decrease in tonnages, which explains lower process emissions as well as lower use of fuel. Additionally, continuous improvement activities have been performed around sites maintenance to improve the landfill gas capture and further optimization of routes through the Green Collective initiative.

The direct emissions (scope 1) caused by Renewi Netherlands and Renewi NV over FY23 amounted to 472,150 tonnes of CO2e and consisted in about 74% of direct process emissions (such as landfill gas, composting, soil cleaning process), and 26% of fuel consumption.

Within fuels, the most widely used one is diesel, in our CW NL and CW BE divisions, especially for fueling the trucks. Fuel consumed by lease cars is only responsible for only 0.5% of Scope 1.

The indirect CO2emissions (scope 2) for FY23 (market-based) amounted to 35,241 tCO2e and are almost entirely caused by purchased electricity on locations rather than in fleet. Note: at the moment the energy consumption of EV trucks is added to the site energy bills at the point of charging, therefore showing in the site-related electricity consumption.

Insight into the CO2 footprint FY24

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 tCO2e, maintaining 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

  1. Renewi Nordsol and Shell focus on BioLNG
  2. Renewi, IKEA and Return mattress open fourth mattress recycling plant
  3. 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:

  1. Green Fibre
  2. Reverse logistics

The CO2-performance ladder certificate can be found here.
