Decarbonization is at the core of the 3rd pillar of our “Act for Positive Mining” CSR roadmap: “Transforming our value chain.” In particular, Eramet is committed to reducing its Scope 1 and 2 CO2 emissions by 40% in 2035 compared with 2019, a target validated by the SBTi (Science-Based Target initiative) in 2021.

A strategy in step with the transition underway in the industry as a whole

Reducing our impact on the climate involves not only decarbonizing our activities, but also developing new technologies in partnership with industry peers, academics and suppliers, as supporting our customers’ carbon reduction efforts.

Our response to climate change is thus based on the following principles:

  • reduction of the Group’s Scope 1 and 2 CO2 emissions;
  • supporting customers and suppliers in their efforts to reduce greenhouse gas emissions;
  • developing our activities in the metals needed for the energy transition.

4 drivers of decarbonization at Eramet

Each of our sites has a program tailored to its specific circumstances that is aligned with the Group’s objectives. The main initiatives aimed at decarbonizing our activities focus on the following:

  • the energy efficiency and efficacy of our production facilities (energy efficiency, electrification, recycling, etc.);
  • the decarbonization of pyrometallurgical processes in furnaces by replacing fossil carbon-based reducing agents with bio-reducers;
  • the decarbonization of electricity consumption, either partially by replacing fuel oil with natural gas or entirely by using renewable energies;
  • CO2 capture, utilization and sequestration.

Our decarbonization projects

Eramet Sauda

Eramet Sauda: a pilot site for decarbonization and industrial innovation

Located in Norway and powered entirely by renewable hydroelectric energy (750 GWh/year), Eramet’s Sauda plant is a model of low-carbon manganese alloy production.

The site hosts several innovative projects aimed at reducing its carbon footprint:

  • Bio-reduction: trials are underway to replace fossil coke with vegetal charcoal in furnaces, a more environmentally-friendly alternative.
  • Energy recovery: an Energy Recovery Unit (ERU) captures furnace gases to produce up to 250 GWh/year of electricity and heat, improving the site’s energy efficiency by 30% to 40%.
  • CO₂ capture and storage (CCS): a pilot project launched in August 2025, aims to capture 70% of the site’s emissions, i.e. around 260,000 tonnes of CO₂ per year.

Eramet Sauda is thus establishing itself as a bona fide energy transition laboratory, working to bring about responsible manganese processing.

Bio-réducteurs

The use of bio-reducers

In 2023, Eramet launched a Project Department dedicated to bio-reduction, i.e. the use in furnaces of biogenic reducers derived from renewable organic materials (wood, agricultural waste, etc.) to replace fossil coke. These reducers are carbon-neutral, as the CO₂ emitted during their use is offset by the CO₂ captured during plant growth. Several trials are underway to tailor these solutions to the Group’s industrial processes in its furnaces. A forestry waste recovery program has been launched in Gabon, and tests will be carried out in 2024 and 2025 at the Moanda, Marietta and Kvinesdal sites, to gain a better understanding of the impact of these new reducing agents on smelting processes.

In Gabon, an electric conveyor belt replaces trucks

An electric conveyor belt was installed in 2023 to transport the ore from the Okouma plateau in Gabon, 200 meters above sea level, to the site’s loading area. The belt has eliminated the need for trucks, thereby eliminating the associated fuel consumption. It is also equipped with a system that generates electricity from the ore’s gravitational potential energy.

Centrale-solaire

A photovoltaic solar power plant in Senegal

Eramet Grande Côte and JUWI Renewable Energies announced in November 2024 that they were working together to develop a hybrid solar power plant with a battery energy storage system. The solar power plant will produce 20 MW of solar energy and will be equipped with 11 MW/11MWh of battery storage. This facility will significantly reduce fuel consumption and CO2 emissions from Eramet’s Grande Côte mineral sands mine (approximately -25,000 tonnes of CO2). It is scheduled to be operational by 2026.

Eramet-Norway-Kvinesdal

Carbon capture, utilization and storage (CCUS) project in Norway

In October 2024, Eramet and LanzaTech, a company that specializes in carbon recycling, announced the launch of a project to decarbonize our manganese alloy production activities. Phase 1 of the project will focus on the “Carbon Capture & Utilization” (CCU) of the carbon present in the gases produced by the pyrometallurgical furnaces at Eramet’s Porsgrunn plant. About 30% of this carbon will be transformed into ethanol in a plant built by LanzaTech (about 50,000 tonnes of CO2e/year).

A second phase of the project is being developed to capture and permanently store (Carbon Capture and Storage, or CCS) the remaining 70% of CO2 (approximately 150,000 tonnes of CO2e).
