Climate change

The sustainable future of mining depends on strong action, today.

#A sustainable future

We recognise climate change and the global transition to a lower-carbon economy. We acknowledge that while the pace of transition may fluctuate, the underlying drivers remain and the physical impacts persist. Thiess are committed to managing climate-related risks and opportunities, decarbonising and diversifying our business, while supporting clients to responsibly produce essential commodities.

This year, we strengthened climate resilience by analysing regional weather trends, improving monitoring of extreme weather and climate‑related downtime, and delivering weather webinars to build climate awareness across our operations.

The Thiess Group has refreshed its climate scenario analysis, developing bespoke climate snapshots for each region to enhance climate awareness.

Our actions to achieve net zero:

01

Disclose our approach and progress transparently

We publicly disclose our Scope 1, 2 and 3 emissions and climate-related risks and opportunities using the Task Force on Climate-related Financial Disclosures (TCFD) framework, and report on our performance in the annual Thiess Group Sustainability Report.

02

Decarbonise our mining services

We are working on improving energy efficiency and displacing diesel from our operations. We invest in technology-centred partnerships focused on both short-term lower emission transition solutions and long-term zero emission concepts. These include commercially available, renewable energy agreements, hydrogen fuel technology, and hybrid retrofit technology and battery-electric options for large mining fleet.

03

Drive growth in commodities for a low carbon future

We're leveraging our core capabilities to continue diversifying into commodities and services that are essential for clean energy technology. We will rebalance our thermal coal portfolio to be less than 25% of Thiess Group revenue by the end of 2027. Our strong progress against our 2027 target motivated the Group to set an additional diversification target in 2023. We are on track to further rebalance of our portfolio to consist of less than 20% thermal coal revenue by the end of 2030.

04

Contribute to a just, fair and equitable transition to zero emission energy

We support our clients, communities and governments in their efforts to navigate the transition. We support a responsible phase-down of thermal coal, and are working to minimise disruption to employees and communities currently reliant on thermal coal for their livelihoods by actively investigating opportunities for our people outside of thermal coal.

05

Improve Thiess’ resilience to climate change

We're investing in climate monitoring to improve our responsiveness to extreme and chronic changes in the climate that could impact our people, operations, communities and the environment.

06

Develop the next generation of talent

We're investing in our people, to enable them to lead efforts in the decarbonisation of our portfolio and the development and deployment of new technologies to support our transition to net zero.

Interim targets towards net zero emissions by 2050^
