Climate change resilience

COP27 highlighted the need for action to address the risks of climate change as the top global agenda. Response actions include urgently reducing GHG emissions, building resilience, adapting to the inevitable impacts of climate change, and enabling climate action in developing countries.

Climate adaptation, resilience and transition refer to our capacity to adjust to current and anticipated climate change-related risks, and capitalise on strategic opportunities presented by a low-carbon and resource-constrained economy.

Exxaro's response to climate change emphasises the sustainability imperative through environmental, social, financial and legislative aspects. Our strategic objectives support our efforts to contribute to a just transition. Delivering on this requires a systemic and institutional approach, with all aspects of our business involved in this transition.

Our approach

Two of Exxaro's strategic objectives – to transition at speed and scale and to be carbon neutral by 2050 – outline our goals and commitment to fundamentally change our business to positively respond to the climate change agenda. Our Climate Change Response strategy, decarbonisation plan, alignment with TCFD recommendations and linked STI scheme across the business support the achievement of these objectives. The STI scheme incentivises carbon and energy reductions across the group. The principles and mechanisms to respond to climate change are integrated throughout our business, and are central to our thinking and actions.

We mitigate climate change and its impacts through:

  • Reducing our carbon footprint, guided by our Climate Change Response strategy and decarbonisation plan. In the short term, our operational energy efficiency projects, renewable energy self-generation and potential divestment, will result in emissions reduction of 40% by 2026 for scope 1 and 2, based on a revised 2022 baseline. We are developing the medium and long-term elements of our decarbonisation plan, including the capital alignment implications
  • Measuring, monitoring and reporting data and performance
  • Incentivising performance through the STI scheme
  • Prioritising adaptation and resilience of our operations and host communities
  • Creating awareness during regular stakeholder engagements
  • Supporting research and development
Climate Change Response strategy and decarbonisation plan

Carbon emissions reduction approach and management

Carbon emissions reductions are driven by our efforts in energy management and the implementation of cleaner energy sources at our operations. South Africa has revised its nationally determined contribution (NDC) target range for 2025 to 398MtCO2e to 510MtCO2e and for 2030 to 350MtCO2e to 420MtCO2e compared to 398MtCO2e to 614MtCO2e between 2025 and 2030 as communicated in the first NDC. The revised NDC requires us to do more to support the country's transition to a low-carbon economy

To ensure comparability, Exxaro measures, manages and reports energy and carbon data in terms of the GHG Protocol's Corporate Accounting and Reporting Standard. Our scope 1, 2 and 3 emissions are monitored and reported annually.

Scope 1 Direct GHG emissions (measured in tCO2e) from sources owned or controlled by Exxaro using diesel, petrol, gas, explosives and limestone. Production-related fugitive methane emissions are also included.
Scope 2 GHG emissions from electricity generated by utility Eskom and purchased by Exxaro
Scope 3 Emissions outside our control but emanating from our products or value chain activities such as customers burning coal supplied by Exxaro
GHG emissions recorded over the past three financial years

Internal performance measures External performance measures
  • We monitor performance closely through monthly energy and carbon data reporting at all levels
  • Monitor and report on scope 1, 2 and 3 emissions annually using the operating control accounting approach
  • Our 2022 STI scheme tracks carbon and energy reductions at group and BU levels to inform employee and executive reward performance
  • We continue to investigate data solutions that will give us real-time feedback, which we believe will allow us to respond quickly to emerging issues and opportunities to reduce our emissions
  • We have participated in the CDP climate change programme since 2008 and the CDP water programme since 2010, and supplier engagement since 2019
  • Our CDP climate change inputs provide information on our energy consumption and intensity, carbon emissions measurement and cost performance at BU and group levels. This information is audited and assured externally every year
  • The CDP water and supplier engagement programmes help us ensure that we align water security and supply chain risks to impacts of climate change

In the 2022 CDP climate report, Exxaro is ranked in the management category (B score), which is higher than the coal mining sector average of C.

For more information on our CDP performance, please refer to www.cdp.net and the databook.

Carbon tax compliance

Promulgation of South Africa's Carbon Tax Act, 2019 (Act 15 of 2019) contributed to GHG emissions reduction being a business imperative as this could affect our financial and sustainability performance.

Governed by the Carbon Tax Act, the current carbon tax rate is R144/tCO2e with several tax-free allowances. Exxaro's carbon tax liability for 2022 was R2.6 million for production-related emissions, ie fugitive methane emissions associated with the coal seam.

Accountability and responsibility

The RBR committee manages climate change risks and opportunities. The SERC ensures we align with just transition principles. The ESG steering committee's role is to support Exxaro's ongoing commitment to environmental, health and safety, corporate social responsibility, corporate governance, sustainability, and other relevant public policy matters.

Becoming carbon neutral through our decarbonisation plan

Current decarbonisation initiatives

Our decarbonisation plan includes a range of projects to reduce our emissions. These include self-generation solar PV projects and ongoing operational efficiency programmes, primarily focused on reducing diesel and electricity consumption. While it is critical to reduce our direct emissions, we are also focusing on reducing our indirect emissions. The largest contributor to our indirect emissions profile is our scope 3 emissions. It is also imperative for our stakeholders to understand the impact and importance of climate change mitigation, adaptation, and resilience. We have several ongoing educational and awareness initiatives with stakeholders across our value chain. While the impact of these initiatives cannot be measured in terms of tCO2e saved, they are critical to ensuring that we take everyone along with us on our journey and that our transition is just. We have already seen changes in behaviour by our employees, with increasing interest in reducing their personal carbon footprints.

Roadmap to become carbon neutral

Carbon intensity baseline assessment boundary for operational BUs and not mines in closure

  • Rebased carbon intensity baseline
  • Established decarbonisation portfolio management office and interconnected workstreams
  • Total carbon intensity: 4.9tCO2e/kTTM
  • Electricity intensity: 13MWh/kt
  • Diesel intensity: 2 042L/kt

  • Reduced carbon intensity by more than 8% against the 2018 baseline with focus on managing electricity and diesel consumption
  • Decarbonisation baseline:
    • Scope 1: 327ktCO2e
    • Scope 2: 503ktCO2e
    • Total: 830ktCO2e
  • September 2021: ECC divestment
    • Scope 1: 59.2ktCO2e
    • Scope 2: 25.5ktCO2e
    • Total: 84.7ktCO2e
  • Total carbon intensity: 5.51tCO2e/kTTM (13% increase due to fewer tonnes of material moved)
  • Electricity intensity: 14.18MWh/kt (10% increase mainly due to production challenges)
  • Diesel intensity: 2 000L/kt (2.05% increase mainly due to production challenges)

  • Implemented STI scheme to track water and energy security and efficiency targets (related to diesel and electricity consumption)
  • Delivered on targets set for first half of year (BUs on or beyond targets)
  • Scope 2: 637ktCO2e
  • Scope 1: 333ktCO2e
  • Energy efficiency projects (13ktCO2e reduction)
  • Total carbon intensity: 5.54tCO2e/kTTM (0.5% increase due to increased levels of electricity consumption associated with the ramp up of the GG6 plant)
  • Electricity intensity: 3.37MWh/kt (3.9% increase mainly due to an increase in electricity consumption at the GG6 plant area
  • Diesel intensity: 4.88MWh/kt (7% decrease mainly due to low production figures in some BUs, eg Belfast, and energy efficiency initiatives targeted at reducing diesel consumption)

Actively reduce scope 1 and 2 emissions by at least 40% through energy efficiency projects, self-generation and consumption of renewable energy at our operations and potential divestment. We will also continue working with our value chain partners to reduce scope 3 emissions and contribute to implementation of renewable energy projects by our value chain partners.

Carbon neutral for scope 1 and 2 emissions. Our objective is to also contribute to carbon neutral value chains.

How we performed

As our decarbonisation journey moved into implementation, we included climate change metrics in scorecards across the business and finalised our capital allocation model (integrated report), supported by analytics tools that informed strategic decision making. These tools enabled incremental steps towards emissions reductions against significant logistics constraints for our vehicle fleet, at our Grootegeluk operation. We addressed these constraints by implementing optimisation solutions that rectified higher carbon intensity per tonne of product mined due to sub-optimal equipment use. The optimisation solutions include:

  • Mine digitalisation
  • Dispatch and fleet allocation optimisation
  • Truck payload management
  • Shovel and truck cycle variability management
  • Road condition and construction opportunities
  • Out-of-cycle waste reduction

Total carbon intensity was 5.54tCO2e/kTTM (2021: 5.51tCO2e/kTTM) with scope 1* at 1.90tCO2e/kTTMRA (2021: 1.91tCO2e/kTTM) and scope 2* at 3.64tCO2e/kTTMRA (2021: 3.6tCO2e/kTTM). This translates to a 0.5% increase in carbon intensity due to the ramp-up of operations at Grootegeluk plant 6. Based on production tonnages in 2022, electricity intensity increased by 3.9% to 3.37MWh/kt (2021: 3.24MWh/kt) and diesel intensity decreased by 7% to 4.88MWh/kt (2021: 5.25MWh/kt). While our intensity increased, absolute GHG emissions decreased.

* All of Exxaro's BUs' carbon emissions are taken into account for these two intensity calculations.

Future focus

Our primary focus areas in 2023 will include climate adaptation (at our operations and host communities), using climate-related data to predict the impacts of extreme weather events on our operations, communities and social impact programmes. In addition, we will intensify energy efficiency and mitigation efforts at BUs. We are evaluating various opportunities to reduce emissions, including biofuels, compressed natural gas, electric vehicles, carbon and methane capture and storage, solar farms, green hydrogen and emissions offsets.

Case study: Hlobane implements nature-based solution for climate change mitigation

We are planting trees as part of our mine closure process at Hlobane in KwaZulu-Natal to address climate change. This cost-effective nature-based solution enables carbon sequestration by absorbing carbon dioxide in the atmosphere while mitigating the impacts of climate change on people and the environment. It also addresses biodiversity management and land degradation by sustainably managing, protecting or restoring natural ecosystems. The project provides employment opportunities for local communities and forestry entrepreneurs.

We are investigating an evidence-based approach to quantifying, measuring and managing carbon sequestration results from this afforestation and reforestation initiative.
