The road to net-zero emission

Breakdown of Proximus CO2 footprint in 2021 (Scope 1 – 2 – 3)

Table like graph illustrating the co2 breakdown
(the figures are rounded)

Breakdown of Proximus CO2 footprint in 2020 (Scope 1 – 2 – 3)

Scope 1: 6% - 27% Ktons Direct emissions from fossil fuel combustion and refrigerant gases

Scope 2: 0% - 0 Kton Own indirect emissions from affiliates electricity usage

Scope 3: 94% - 433 Ktons Proximus' indirect emissions in the value chain

Scope 3 includes:

Procurement 79% ,Goods & services, Upstream transportation and distribution

Proximus’ operations4%: Fuel & energy (excl 1 & 2), Waste, Business travel, Employee commuting

Customer use of products 17%, Leased assets, Downstream transportation and distribution, Use of sold products, End-of-Life treatment of sold devices

Scopes 1 and 2: Our direct and indirect emissions

Looking at our carbon footprint, we are managing our own emissions quite effectively. Since 2019, the company made the switch to 100% renewable electricity for example. At the same time, Proximus is working on creating a more energy-efficient network by focusing on its technical buildings, mobile network, fixed access network and data centers. And it’s also investing in more sustainable transportation, for instance through the CULT project in Antwerp, a joint delivery platform in collaboration with companies like Danone, Delhaize, Jacobs Douwe Egberts, Pro-Duo, Telenet and Torfs.

To date, 26.6 Ktons of our own emissions remain to be reduced in order to reach zero by 2030. As such, we have focused on electricity sourcing and electricity consumption. In 2019, we made the switch to 100% renewable electricity. Additionally, we are working on creating a more energy-efficient network by focusing on our technical buildings, mobile network, fixed access network and data centers, and have invested in more sustainable transportation.

Scope 3: Indirect emissions resulting from our value chain

Our indirect emissions, which are highly concentrated within our procurement activities, are 16 times the amount generated by our own operations. They account for about 94% of our indirect emissions.

Of the emissions generated by our value chain, more than half are concentrated among our top 18 suppliers and the other half is generated by a long tail of over 4,000 vendors: a combination of large global enterprises and smaller, local players who often lack the resources needed to manage their carbon footprints.

Reducing these indirect emissions is our main challenge; it requires our suppliers to commit to reducing their GHG emissions and engaging more sustainable supply chains.

On the road to true circularity

The 5 Circular Business Models
Network & Data Centers
Real Estate & Facilities
Circular Inflow
  • Baseline & target set for CPE
  • Refurbished phones offer
  • Fairphone in catalogue
  • CPE redesign done
Network design assessment
New circular headquarter building
Sharing Platforms
Mobile network sharing
(e.g. Lease model)
CPE-as-a-Service model (residential segment). Smartphone-as-a-Service model (enterprise segment)
Product Use Extension
Repair & refurbishment of devices
Resell of network equipment
Refurbished offers for furniture and assets
Resource Recovery
(End of life recycling)
Collection program for CPE & smartphones
Recycling upon network phase out

For circularity, we have identified the relevant circular domains for telecommunication providers as:

  • Devices
  • Network & data centres
  • Real estate & facilities

Several initiatives are in place across all 5 commonly accepted circular business models. For example, we have refurbished phones in our catalogue, we design the devices we put in the market so they are easy to refurbish. We also do this for our network, where we recover both copper & network equipment and are sharing our mobile network with Orange.

Furthermore, we have a zero-waste ambition by 2030. We currently convert 12% of our residual waste into electricity & heat energy in waste treatment facilities and recycle, reuse, or reprocess the remaining 88%.

Initiatives for reaching our ambitions

Our future initiatives can be found in 3 main action domains:
Energy, circularity & supply chain are the main areas to achieve our net-zero & truly circular ambitions

Energy, circularity & supply chain are the main areas to achieve our net-zero & truly circular ambitions

100% renewable energy
Truly circular
Net-zero emissions
Action domains


  • Fossil fuel free buildings
  • Clean transportation
  • Energy efficiency programs


Filling the gap accross the 5 circular business models with focus on:

  • mobile devices
  • refurbishment in enterprise segment
  • circular network plan
  • waste plan

Supply chain

  • Strong Supplier Engagement Program
  2030 2040


To achieve 100% renewable energy by 2030, we will stop using fossil fuel in our buildings and fleet and ensure that our suppliers and partners follow our lead. We will also focus on efficiency programs that mitigate the high energy use associated with telecom infrastructure to maintain a flat electrical consumption. Plus, we will continue to phase out our technical buildings and renovate our headquarters in Brussels to have zero emission by 2027. Our other office buildings will get alternative heating technologies.

Furthermore, we want to implement a completely green, local electrical supply for our company. We already use 100% green electricity. And by 2026, we will work with more local energy sources, through our own investments and long-term partnerships with Belgian wind and solar plants.


Across the 3 relevant telco domains, we will become truly circular by 2030 by:

  • Implementing a further circular push for mobile devices by addressing our mobile business models, increasing recycling habits, and more conscious buying. 
  • Promoting refurbishment in the enterprise sector by deploying an effective return flow of B2B devices. 
  • Continuing to enhance our circular network and set circularity targets for the equipment in our customers’ homes and offices.
  • Developing a roadmap detailing the clear steps to be taken to fulfil our zero-waste ambitions by 2030.

Value Chain

We will continue to work closely with our suppliers to encourage them to reduce their carbon footprints and achieve more sustainable supply chains. In addition to our Circular Manifesto, we will be implementing clear and binding commitments, with detailed expectations and KPIs for our suppliers.
