Corporate Social Responsibility (CSR)

Towards a long-term partnership

The Group attaches great importance to the ability of its suppliers to offer long-term partnerships and ensure a high level of safety, reliability, competitiveness and innovation, while guaranteeing that ethics and sustainable development are also taken into account.

The recognition of ethics and sustainable development-related challenges in procurement practices are formalized in the Procurement Code of Conduct, translated into 13 languages, which applies to all Group employees engaged in Procurement activities, and the Sustainable Procurement policy, which lays out the guidelines to be applied by the procurement departments. It encompasses ethical, social and environmental aspects of the procurement processes, and defines the supplier risk prevention approach in terms of sustainable development.

Our requirement to suppliers

The Supplier’s Code of Conduct aims to promote and enforce practices relating to human rights, ethics, the protection of the environment and safety.

Air Liquide expects each of its suppliers to respect the Group's ethical principles and to ensure that this Code of Conduct is respected by all their employees and subcontractors.

A sustainable development clause is included in the Group’s new contracts and framework agreements. This clause covers the option for Air Liquide to assess the supplier’s sustainable development performance, as well as the supplier’s obligation to implement adequate corrective measures. It also includes a compulsory reporting element for the supplier, in particular on safety, energy and water consumption, atmospheric emissions, as well as human resources.

Assessment of suppliers’ performances

A sustainable development performance below Air Liquide's expectations will result in the setup of a corrective action plan whose progress will be subject to regular evaluations.

In case of insufficient progress, Air Liquide may suspend the commercial relationship with the supplier.

Our commitments to suppliers

Air Liquide strives to build long-lasting and balanced relationships with its suppliers, in an environment of mutual trust. The Group, for example, formalized this commitment in France by signing the “Mediation des Enterprises” Charter for responsible supplier relations.

Air Liquide is committed to promoting sustainable development among its suppliers and to supporting them in their progress approach.

Compliance with Customs and Export Control Regulations

Supplier shall comply with and ensure compliance with all applicable Customs and Export Control regulations.
