Diversifying to support the energy transition
Thiess is growing our commodities portfolio to include metals and minerals critical to the energy transition, and developing services to enable sustainable mining.
#Progress on diversification
The race is on to develop cleaner, lower emission technologies to reduce the world’s dependence on fossil fuels.
The mining sector plays a pivotal role in supplying the metals and minerals critical to the energy transition.
In 2025, Thiess remained on track to achieve strong progress on our diversification targets:
- Less than 25% total revenue from thermal coal by the end of 2027; and
- Less than 20% total revenue from thermal coal by the end of 2030.
- 15 metals and minerals projects secured contracts and extensions in 2025 including for copper, gold, iron ore, antimony, and polymetallic base metals.
We launched Thiess Asset Services, a standalone service focused on delivering flexible asset lifecycle solutions, and continued providing asset planning and maintenance services for clients in Asia, Australia and the Americas.
