ACC has published its 4th CSR Report for 2025, a year that marks a key milestone in our development and in the establishment of a European battery supply chain.

Against a backdrop of a demanding industrial ramp-up, this report reflects both the progress made and the updating of our CSR approach, with the formalisation of our roadmap.

 

2025: a year of learning in a challenging environment

The year 2025 is part of a sustained development trajectory, characterised by:

• the ramp-up of our Gigafactory in Billy-Berclau Douvrin;
• the onboarding of new staff, their training and the strengthening of health, safety and environmental skills;
• the pursuit of technological innovation (63 patents filed, ACC ranked in the INPI’s top 50);
• the equipping of new vehicles (PEUGEOT e‑3008 and e‑5008, DS No. 8, Opel Grandland).

Against a backdrop of greater market uncertainty, ACC has also adapted its organisation, whilst pursuing its industrial and environmental ambitions. European support, notably via the Innovation Fund 2024, sends a strong signal to the sector.

 

An updated CSR approach, structured around three pillars, and an associated roadmap

ACC’s CSR strategy, updated at the end of 2025, is built around three complementary pillars:

• Caring for people and communities
  Developing skills, ensuring safety and implementing our company-wide agreement on quality of life and working conditions
• Delivering innovative and sustainable solutions
  Designing innovative, competitive and sustainable solutions to serve our customers and support the transition to carbon-free mobility
• Fostering industrial sustainably
  Developing the HSE&S skills of our employees and site contractors, managing priority environmental impacts (energy, water, waste) and preventing risks

This approach covers the entire value chain, from the sourcing of raw materials to the recycling of batteries.

 

Managing our carbon footprint

To keep the carbon footprint of our products and operations as low as possible.
In 2025, ACC continued:

• to structure its approach  across Scopes 1, 2 and 3,
• to roll out its energy management system,
• to optimise consumption and industrial processes, in line with the energy policy published in June.

Objective: to achieve a carbon footprint of less than 40 kg CO₂eq/kWh at module level.

The supply chain accounts for a major proportion of the footprint (around 90% for our initial products), which underlines the importance of the work undertaken with suppliers, the primary focus being the electrification of their production processes.

 

People at the heart of our priorities: skills development and safety culture

ACC continues to develop and train its teams :

• nearly 2,900 people working at our sites by the end of 2025
• 381 plant operators trained and 77 supervisors trained (94%)
• a workplace equality index of 93/100.

The year was marked by several key initiatives to strengthen the HSES culture:

• launch of the Safety and Environment Dojo at Billy-Berclau Douvrin and the Safety Box at Nersac
• The first edition of our internal ‘HSES Awards’ competition to promote a safety culture across all our sites
• The roll-out of eight new internal standards to govern practices relating to the environment, security and fire safety.

 

Responsible business conduct: strengthening requirements and the duty of care

ACC is continuing to roll out its measures relating to ethics and responsible conduct:

• 100% of at-risk staff trained in anti-corruption
• Strengthening the duty of care across the supply chain. In 2025: 
  •  100% of priority suppliers have been assessed against CSR criteria
  • 94% have signed up to the Sustainable Supply Chain Charter

The support programme for our suppliers, set up in partnership with EcoVadis, is bearing fruit: their overall CSR maturity has improved by 4.5 points in one year, across all four pillars assessed (environment, workers’ and human rights, ethics and responsible procurement).

 

Key takeaways

• A year of demanding but formative ramp-up, with renewed support from European institutions.
• A consolidated CSR approach integrated into the business model
• Confirmed priorities: workplace safety, staff training and risk prevention, environmental initiatives and carbon footprint, a sustainable supply chain, and the safety and quality of our products for our customers and electric vehicle drivers.
• An unchanged ambition: to accelerate sustainable mobility, accessible to as many people as possible.
