Companies dedicate the third of their income to their expenses, accordingly to their purchases. 

However, their knowledge remains weak regarding the environmental and social impacts of the products or services they buy. IMS has then developed a project to raise awareness among buyers about a  sustainable approach to purchasing, which takes into account the origin of the products and their impacts, and the reality of prices that are charged.

"Buy its products or services in a search to reduce environmental and social impacts, while keeping a global cost under control, that's the goal of sustainable or responsible purchasing" Sandrine Grumberg, Director ViaSourcing



Previous working groups

Between 2012 and 2016, two collaborative working groups were launched with the objective of working on specific themes of purchases. Two practical guides synthesizing the work of these groups have been published by IMS. They address both theoretical aspects (national context, norms, ...) and much more practical aspects by proposing tools and concrete examples. (see tabs FOOD and COMMUNICATION)

Faced with the new challenges faced by purchasing professionals and to meet the demand of its member companies, IMS Luxembourg launches the new buyers' club "PURCHASES OUT OF THE BOX".

The Club brings them together in a framework of exchange and privileged sharing between peers and offers tools and concrete examples to instil a sustainable aspect into its purchasing policy.

Each session explores a specific topic, its stakes and practical application, and is complemented by a webinar that gives buyers the opportunity to discuss with our expert about a concrete problem of their organization or a current topic.


The first session focused on the topic of changing the profession of buyer: "Buy sustainable, a new business and new practices?" Buying sustainable products requires adapting to certain constraints: lack of time or practical information, conflicting commitments ...
Anxious to support you in this new approach, the Buyers Club allows you to meet in a framework of exchange and privileged sharing between peers and offers you tools and concrete examples to instill a lasting aspect to your policy. shopping.

For the second meeting of the club, the exchanges were focused on the selection criteria for purchases.

The third meeting focused on the issue of stakeholders: suppliers, management, technical services, internal specifiers (marketing, general services, etc.). How to engage them, motivate them and lead them to change their vision of purchases?

The first working group looked at the problem of food purchases from 2012 onwards. Indeed, sustainable food purchases are a relatively new topic, treated regularly for school canteens or from a nutritional point of view, but which remained largely unexplored for companies.

The subject was approached from the specific needs of the buyers and their company, such as the provision of seasonal or local products, or the reduction of food waste.

The knowledge and research of the working group has been gathered in a book that presents the internal approaches of the various participating companies and the concrete solutions that have been found. Five pillars are discussed: product origins, their distribution, consumption, waste and cross-cutting approaches.


"This project allowed me to highlight Sodexo's policies in favor of sustainable development, including the promotion of products from fair trade or from Luxembourg's terroir" Mathilde Antoine-Thanner, On-Site Service Solutions, Sodexo

The practical guide is available to members upon request. More information here.

Starting in 2017, a second working group focused on the theme of communication through a practical training cycle aimed at concretely implementing sustainable corporate purchasing.

This cycle was initially centered around five IMS member companies, each of which has deepened a particular issue, from the choice of suppliers to events and communication gadgets. The working group was then expanded to share the fruits of the first months of reflection during participatory workshops.

Good corporate practices, useful information and practical tools can be found in the practical guide on sustainable purchasing in communication, which summarizes the information and research carried out in preparation for the training cycle. Five axes are treated: the choice of paper, the organization of a sustainable event, the choice of communication objects, the selection of suppliers, the dematerialization.
