Climate change presents a complex landscape of challenges for the mining industry, ranging from direct physical impacts on operations to the systemic risks associated with a low-carbon transition.

Our approach to identifying and minimising these risks is framed by our Climate Change Strategy, which integrates climate considerations directly into our strategic and operational planning. This strategy, together with our Decarbonisation Strategy, seeks to ensure that we work to insulate our operations against the physical climate risks that may impact both our operations and host communities, implement appropriate climate disclosure systems while maximising further opportunities for cost-saving energy efficiency programmes.

Embedded in our Decarbonisation Strategy is our net zero roadmap, which charts the pathway to net zero Scope 1 and Scope 2 GHG emissions by 2050. This roadmap outlines a multi-pronged approach involving the implementation of renewable energy projects; electrification of our mining fleet; and the use of lower-emission power sources.

Embedded within our strategy is our net zero roadmap that sets out our pathway to net zero Scope 1 and Scope 2 GHG emissions by 2050.

Roadmap to Net Zero

Our Decarbonisation Journey

AngloGold Ashanti has set an interim target of cutting Scope 1 and 2 greenhouse gas emissions by 30% by 2030 through a combination of renewable energy projects and initiatives which improve efficiency or use lower-emission power sources. We have taken significant steps towards this target with the completion of our renewable energy project at Tropicana in Australia and switching to the national power grid at Geita in Tanzania.

Tropicana Hybrid Renewable Energy Plant

AngloGold Ashanti took a significant step forward in our decarbonisation journey following the transition to commercial operation of the renewable energy facility at Tropicana in February 2025.

The project involved integrating 62MW of wind and solar generation into the existing 54MW gas-fired power station at the mine to create the largest off-grid hybrid power system in Australia.

Constructed by Pacific Energy, the project involved more than 200,000 on-site labour hours and was delivered safely on time and on budget.

Supporting our strategy to reduce our global net carbon emissions from energy use, the designed GHG emissions reduction of the combined hybrid renewables system is 65kt CO2e annually over 10 years.

The decarbonisation journey at Tropicana started in 2016 when diesel power generation was replaced with natural gas generation enabled by the extension of the Eastern Goldfields natural gas pipeline.

Pacific Energy owns and operates the off-grid hybrid power station at Tropicana under a 10-year build-own-operate agreement.

Linking to the TANESCO grid at Geita

With the aim of replacing a significant portion of its diesel generated power at the site with grid power, AngloGold Ashanti worked closely with the government of Tanzania through its power utility, TANESCO to implement the project.

TANESCO financed a 6.1km electricity distribution line (220/33kV) from its Mpomvu substation to a purpose-built substation at the mine while GGML financed and constructed the on-site 33/11kV 80MVA mine substation. The mine will draw an average load of 32 – 34MW, satisfying most of its underground mining and processing power requirements.

TANESCO’s generation system is made up mainly of hydro and thermal-based generation, with thermal power from natural gas making up the largest share of its grid power generation.

The national grid generation mix comprises 65.35% hydropower and a 34.24% thermal component, largely derived from lower-emission natural gas.

This increased availability of renewable energy elevated the project’s total annual emissions reduction to 72,000t. Critically, this strategic shift is currently displacing approximately 80% of Geita’s diesel consumption for power.

Performance in 2025

AngloGold Ashanti set its first emissions reduction targets in 2008, which were met in 2018 and by 2021, we had achieved a 47% reduction in GHG emissions intensity through some fuel switching and efficiency improvements but also due to the closure and divestment of assets.

However, the acquisition of Centamin in late 2024 prompted the adjustment of our 2021 decarbonisation baseline to reflect our larger global portfolio. Our original 2021 Scope 1 and 2 baseline of 1.383 million tonnes of GHG emissions equivalent has been restated to 1.861million tonnes.

By maintaining our 2030 reduction percentage targets against this restated baseline, our absolute commitment for 2030 was adjusted to 1.303 million tonnes of GHG emissions.

In 2025, our absolute Scope 1 and Scope 2 GHG emissions totalled 1.806Mt, lowering our GHG emission intensity by 4.83% to 33.50tCO2e/t of ore treated.
