#1Month1Committed: Louise Langer, E(17) "Transforming the vision of CSR from a constraint into an opportunity"

Sustainable Business

09.14.2025

Louise is a French entrepreneur, co-founder, and CEO of La Boxeuse, a company launched in April 2025 that offers innovative solutions to reduce waste in businesses. These solutions include renting reusable containers and developing a gamified mobile app to raise employee awareness in a fun way.

Before venturing into entrepreneurship, Louise gained significant professional experience in the delivery sector, notably at Jumia and Clone. She also worked at Rocket Internet, an international group specialising in startup launches.

She represents a new generation of entrepreneurs committed to ecological transition and waste reduction in the professional environment.

ESSEC broadened her horizons, particularly through travel to developing countries, where she observed the tangible impacts of climate change (floods in the Philippines, rising waters in Côte d’Ivoire, fast-fashion clothes littering beaches, etc.) and confirmed her interest in ecology and sustainable development. Having worked in e-commerce and mainly in delivery, she saw the limits of a system that prioritises speed over environmental awareness. She decided to take action.

E.S.B.: What is your background, and what made you interested in CSR?

  • ESSEC Grande École after preparatory classes, Law track

  • Creation of ESSEC Solidarités Immigrants, a branch of Wintegreat (now EachOne)

  • 5.5 years in international e-commerce startups: Philippines (6 months), Côte d’Ivoire (3 years), France & Netherlands (2 years)

  • Launch of La Boxeuse, a social and solidarity economy company, in early 2025

Since childhood, I’ve always been drawn to ecology and choices linked to sobriety (e.g., I was passionate about sustainable construction), and I was able to get closer to it through ESSEC’s “Real Estate and Sustainable Development” Chair. But sustainable development was not yet fully present in 2015, so I had to seek it myself in a job market that was still too “elitist” in sustainable development in 2019.

I worked for several years in delivery, a booming sector in many countries, where I learned and developed professionally. When I felt ready, I decided to start my own venture to use my skills in service of the environment.

E.S.B.: How does CSR manifest in your life?

It is present in both my professional and personal life.

At work, I feel I’m in the right place. I reconnect with the entrepreneurial spirit I discovered through internships and early jobs—it’s exciting—and the environmental impact (waste avoided daily) is very satisfying.

Through professional encounters and discoveries (e.g., the Reuse Economy Expo), my personal life is gradually improving: I’m more informed and ethical, and my choices are increasingly responsible.

My ideas give meaning to my work, and vice versa.

E.S.B.: How do you define CSR?

CSR is the awareness a company must have of its environmental impact.

From this awareness comes responsibility: As a key actor and unifying force, a company should make decisions through this lens, considering each choice not only economically but also ecologically (CO₂, waste) and socially (inclusion, non-discrimination).

However, CSR should no longer be seen as a “blocker,” but as a set of engaging, even fun and desirable tools that can also save money in the long term.

E.S.B.: How is it a catalyst for business and what kind of ROI?

A company that is not specifically “mission-driven” or part of the social and solidarity economy must now compete with companies focused on impact (e.g., Impact 40, 120 nominees, green energy companies) that can also succeed.

CSR can no longer be just a line in a company’s annual report to offset polluting actions, because talent is not fooled—they now expect real action.

ROI remains the first question when facing a CSR solution. While difficult to measure, it is much higher than assumed and acts diffusely on many levels. For example, the impact on candidates’ minds from a concrete action (e.g., awareness workshops, reward systems for virtuous behavior) in the long term can outweigh sponsoring a job posting on job portals.

E.S.B.: What would you like to say to ESSEC Alumni and the Club?

It’s always time to open up to more ethical and responsible decisions at any level in your company or life.

The sovereignty of our economy depends not only on legislative choices but also on what happens on the ground, which will guide lawmakers.

So, even if nothing has been done until now, it’s time to start and see CSR as a tool. Joining forces allows us to gain more influence and make it a standard, raise a common voice, and drive change.
