A NEW PERSPECTIVE ON THE ENERGY MODEL

“Be the change you want to see in the world” Ghandi

The positive switch: advancing together every day!


We are convinced that energy excellence and intelligence are unlocked when tech and social innovation come together in a human way. Through the actions we take with our clients and partners, we are making positive progress toward creating value beyond the traditional economy. We are transforming the energy transition into an opportunity for companies, people and the society we live in.

Our Mission

Our mission is based on 3 principles and directly contributes to 11 of the UN’s 17 Sustainable Development Goals (SDGs).

    Our group contributes directly to 11 of these goals.
    They are a global call to action to promote prosperity while protecting the planet. The SDGs recognise that ending poverty must go hand-in-hand with the strategies that develop economic growth and answer a string of social needs (education, health, social protection and employment), while combating climate change and safeguarding the environment.

Beyond the company: co-building transformation


Committing to act beyond company borders feeds collective intelligence and nurtures the emergence of energy strategies and virtuous behaviours - innovations that respond to climate challenges in all fields. These have now evolved into links with a community of actors working for sustainable development and the energy transition, putting us at the heart of new thinking and action. This helps us develop pathways to promote the latest innovations and as well as share the inspirational activities of others. Together we are working to nourish new thinking and mobilise the tools of energy transition.
