We acknowledge the impact of our business operations on the environment and the importance of using natural resources responsibly.

Responsible environmental stewardship

In 2023, the focus on monitoring and reporting was elevated;
this improved overall disclosures across the Group.

Energy consumption 2023   2022 2021 2020 2019  
Grid electricity 54 941   48 083 59 408 59 523 65 035  
Solar 3 095   2 543 1 105 1 190 891

Total energy consumption 60 425   52 703 61 810 61 934 67 322  

The Electrical Engineering and Applied Electronics Segments have the highest energy consumption due to their energy-intensive manufacturing operations. In 2023, the Group’s grid electricity usage increased by 14% to 54 941 MWh (2022: 48 083 MWh). This was driven mainly by increased production at Zamefa and African Cables.

Reunert manages loadshedding through the use of generators and solar energy. Onsite back-up energy from diesel generators increased by 15% to 2 389 MWh (2022: 2 076 MWh) due to more frequent and higher stages of loadshedding. Our solar PV energy output increased by 22% to 3 095 MWh (2022: 2 543 MWh).

The Group acknowledges the need to protect scarce water resources. The Group’s manufacturing processes are not water-intensive. Electrical Engineering recycles and reuses water during manufacturing. In 2023, total water consumption decreased by 3% to 278 205 kilolitres (2022: 285 969 kilolitres). Electrical Engineering recycled 50 034 kilolitres of water (2022: 58 314 kilolitres).

Material use and waste

The Group is in the process of developing a framework to reduce waste to landfill which will be centred around four key pillars: reduce, reuse, recycle and repair. Our process starts with identifying the waste materials generated through our operations and then deciding on the viable interventions to reduce all waste streams.

The Group monitors waste generated through production to identify opportunities for reduction. Reunert has been tracking waste generated across the different business functions over the past reporting periods. Waste generation data gaps have been identified and focused action plans will be developed to improve reporting. The summary below reflects waste volumes generated across the Group:

Waste (tons) 2023   2022  
Based on available data        
Waste to landfill1 166 314   435 266  
Recycled waste 29 963   163 840  
Hazardous waste 7 567   32  
Total 278 205   285 969  
1 Waste to landfill waste was reduced by 62% in 2023.

Adapting to changing economic context and energy transition

Responsible environmental stewardship highlights

Reunert upholds strict requirements for environmental management compliance. The Group’s transformative offerings include renewable energy and smart energy management solutions.



Reunert makes annual submissions to the Carbon Disclosure Project (CDP) – see disclosure report on our website1.


CDP provides a standardised reporting framework that allows Reunert to compare performance across the Group and identify areas for improvement.


Increased revenues generated from renewable energy products from less than 1% in 2017 to 8% in 2023.


Eskom and municipalities’ energy costs accelerating above inflation Reunert’s strong focus on clean energy as the best option to decarbonisation


Reunert’s business units are supported to obtain ISO 14001 verification to improve their environmental performance through resource efficiency and waste reduction.


Maintain environmental performance, reduce waste and pollution and facilitate recycling Reunert’s ISO 14001 certified facilities:

  • African Cables
  • Nashua
  • Reutech Solutions

Set targets using the TCFD approach and other relevant guidance frameworks.

Next action: Consider performance metrics to be measured at Board level.

Strategy – current status: Reunert recognises the risk presented by climate change.

Next action: Define climate-specific risks that are relevant to each business entity.

Risk management – current status: Risk management framework in place.

Next action: Standardise the assessment of risk across the different business units.

Metrics and targets – current status: GHG disclosure metrics in place.

Next step: Use GHG data to inform decision-making and actions towards combating climate change.

Climate change risk and response

Reunert has considered the risks and opportunities associated with climate change, and these are incorporated into the Sustainability Strategy. Our approach to climate change risks is based on conducting material assessment (identify risks and opportunities), managing risks, monitoring impacts and reporting.

Determine risk response


Track and monitor risks and impacts


Progress towards mitigating risks

Reunert’s identified climate change related risks

The Group’s primary climate-related risks are summarised as follows:

  • ESG-conscious customers require new products, solutions or service methodologies to comply with stringent ESG requirements or support their ESG-aspirations
  • New products and services that better serve ESG-conscious markets can disrupt Reunert’s markets
  • Potential trade barriers to key export markets might challenge our diversification strategy
  • ESG is increasingly important to providers of capital, including current and potential shareholders, bankers and funders
  • The cost of compliance with new legislative and governance requirements or to achieve our own aspirations can decrease profitability
  • Costs across the supply chain may increase as compliance costs are passed on to Reunert
  • There might be supply chain volatility as traditional sources of supply manage their evolution to a lower carbon reality

Responding to climate change through renewable energy generation

Renewable energy is an important initiative to reduce Scope 2 emissions. Reunert has a 297 kW peak solar photovoltaic (PV) system at Reunert Park in Midrand, a 429 kW peak solar PV system at Fuchs Electronics and a 1,1 MW peak system at CBi-Electric: Low Voltage.

Reunert’s climate-related opportunities

Reunert is well-positioned to benefit from the worldwide drive towards a low-carbon future. The Group is capitalising on market opportunities including energy efficiency and optimisation, renewable energy and electrification to improve access to greener forms of energy.

Several of Reunert’s business units are well-placed to develop strategies to maximise these opportunities within electricity management and the digitisation of electrical monitoring. These include optimising energy through digitised control and monitoring and specialised Internet of Things Circuit Breaker products.

Green solutions

Reunert has a local market leadership position in solar energy generation and storage through its business units and joint venture.

Terra Firma Solutions engineers and constructs solar plants for customers and builds in its own plants to generate solar electricity for customers, and Blue Nova Energy supplies battery storage energy solutions. Read more about these business units on Renewable Energy. The Circuit Breaker Cluster develops products that are used in green technology environments. These are well-suited to energy management applications due to their leading technology and small size. Read more on Circuit Breakers.
