Energy & climate change

Climate change is one of the critical global challenges of our time. The impacts of climate change are already being felt, from changes in weather patterns, evolving regulation and stakeholder expectations, and shifts in technology.

Climate change is one of the critical global challenges of our time. The impacts of climate change are already being felt, from changes in weather patterns, evolving regulation and stakeholder expectations, and shifts in technology.

AngloGold Ashanti is proactive and transparent in minimising current and future climate risks. We work to strengthen the climate resilience of our business and our value chain partners, our host communities and the environment in which we operate.

Our Climate Change Strategy aims to deliver measurable progress, focus our actions, and demonstrate our commitment to proactive, holistic, sustained and transparent action on climate change. To achieve this, our Climate Change Strategy adheres to five key Principles:

  1. Seeking to ensure that our core values are upheld through actions arising from the Climate Change Strategy
  2. Maintaining external commitments where we are a signatory, including the ICMM’s Mining Principles, the ICMM’s Position Statement, the WGC’s Responsible Gold Mining Principles and the UNGC
  3. Taking a holistic, long-term, life-of-mine and systemic approach to managing climate risks that includes aspects beyond the fence line, supply chains, communities and ecosystems
  4. Using the latest science-based data, information and knowledge to support decision-making
  5. Disclosing in line with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD). View our Sustainability Report 2024: Climate action and resilience and the 2024 ESG Data Workbook.

AngloGold Ashanti’s roadmap to Net Zero by 2050 is embedded within our strategy and comprises three stages:

  1. Target 100% clean electricity (>70% green) including wind, solar, hydrogen, battery, combined with new storage technologies.
  2. Eliminate the use of fossil fuels and adopt 100% electrification. This will include the adoption of electric material movement technology (conveyors, railveyors, trolley assist, battery technology), energy efficiency initiatives and will be supported by innovative approaches (such as in situ leaching).
  3. Use carbon offsets if this is necessary and as a last resort, particularly where this could support local communities.

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 start of our renewable energy project at Tropicana in Australia and switching to the national power grid at Geita in Tanzania.

In Australia, subsidiary AngloGold Ashanti Australia has completed the construction of a hybrid renewable energy plant which integrates 24MW of wind energy, 24MW of solar energy and a 13MW battery storage system into Tropicana’s gas fired power system.

Owned and operated by Pacific Energy under a 10-year build-own-operate agreement, the plant is one of the largest renewable energy projects in Australia’s natural resource sector and the largest off-grid hybrid power system supplying a mine in Australia.

The facility is the first of its kind to be implemented by the company and will reduce our average carbon emissions by more than 65,000 tonnes per annum over the 10-year life of the Power Purchase Agreement.

At the Geita Gold Mine in Tanzania, a switch diesel generation is being replaced with grid power sourced with a more environmentally friendly combination of energies including hydropower and natural gas. The mine is drawing power from a new on-mine substation linked to Tanzania’s national power grid. The switch will result in an estimated 80% reduction in fuel consumption.

Tropicana Hybrid Renewable Energy Plant

Tropicana is a large open pit and underground mine, located 330km east-northeast of Kalgoorlie in Western Australia. The mine is 70% owned and managed by AngloGold Ashanti with the remaining 30% held by Regis Resources Ltd.

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

Overview

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 61MW 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.

Tropicana’s renewable energy facility supports AngloGold Ashanti’s strategy to reduce its global net carbon emissions from energy use by 30% by 2030, as part of its roadmap to achieve net zero carbon emissions by 2050.

It is the first facility of its kind to be implemented within the AngloGold Ashanti group. 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.

Our performance

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.

HA | GHG emissions intensity (kilotonnes of GHG per tonne treated)
HA | Scope 1 & 2 GHG emissions (kilotonnes of CO2e)
HA | Energy consumption (petajoules)
HA | Energy intensity (gigajoules per tonne treated)

ICMM climate change commitment

In October 2021, AngloGold Ashanti committed collectively with members of the International Council on Mining and Metals (ICMM), to a goal of net zero Scope 1 and 2 greenhouse gas (GHG) emissions by 2050 or sooner in line with the ambitions of the Paris Agreement.
