Direct control
Indirect control

Our total carbon footprint increased by 3% to 341 349 CO2e (2024: 332 735 CO2e) due to higher electricity consumption and improved data completeness for high-intensity facilities.

Improved carbon intensity demonstrates that Reunert is decoupling growth from emissions, proof that the Group can grow profitably in a carbon‑constrained world.

Our carbon footprint is independently assessed every year, based on the GHG Protocol standard using the financial control approach, and covered 42 entities in 2025. The report is available on our website at Sustainability reports

Employee participation in the annual commuter survey

Reunert recognises that employee commuting patterns contribute to our overall carbon footprint and directly influence Scope 3 emissions. To address this, the Group launched an annual commuter survey as part of its broader climate strategy and sustainability reporting.

Survey design and participation

The survey was conducted across all business units and achieved 72% employee participation rate. Questions covered daily transport modes, average commuting distance, vehicle occupancy and fuel consumption.

Key findings (FY25)

  • 81% of employees commute using private vehicles, contributing the largest share of emissions
  • 19% rely on public transport options such as taxis, buses or trains
  • 34% of employees travel more than 30 km per day, highlighting long-distance commuting challenges
  • 4 201 tonnes of CO2e were estimated as Scope 3 commuting emissions, representing 1% of Reunert’s total Scope 3 footprint

Impact highlights (FY25)

  • Employee commuting emissions remain the same compared to FY24

The commuter survey increased employee awareness around climate impacts and confirmed Reunert’s commitment to reducing emissions in the value chain.

Reducing water consumption

Our key actions

  • Water consumption reduction: Implementing strategies to reduce overall water withdrawal and consumption, leading to cost savings and reduced reliance on municipalities
  • Water recycling and harvesting: Exploring on-site water recycling and rainwater harvesting solutions to reduce reliance on freshwater sources
  • Water management: Optimising water usage

The Group acknowledges the need to protect scarce water resources. We prioritise water conservation in business operations, ensuring the sustainable use of water resources and minimising water wastage in line with industry best practice.

We adhere to the requirements of the National Water Act, 36 of 1998. Our manufacturing processes are not water intensive. However, we continue to identify potential water-saving opportunities in our value chain through engagement with stakeholders.

Our total recycled water use increased by 14% to 59 505 kL (2024: 52 104 kL).

Water savings reduce reliance on stressed municipal systems, safeguard operations during shortages and lower costs for both Reunert and our customers.

Borehole water withdrawals increased due to disruptions in the municipal water supply in South Africa.
