We connect people globally to joint climate justice.

Climate change is a global threat that can only be solved in international joint action. To face this challenge we as citizens from Africa, Asia and Europe launched an international initiative: the `One Climate World Cooperative U.A´ abbreviated as One Climate World. with seat in the Netherlands.

Our common goal is to promote climate neutrality and access to clean energy. Therefore, we call people to invest 1% of their income. The common sum will be distributed fairly between the Global North and Global South into renewable energy in order to act against climate change to save the planet for future generations.

Our projects create jobs and liberate people from energy poverty in the areas most affected by climate change. Participating citizens receive dividend on their investment. Our projects are proof that the fight against climate change is possible for everyone. Regardless of the amount of their income.

Where politics does not act fast enough, we want to break new ground – so far in The Netherlands, Germany, Rwanda and South Africa. Our journey has already begun.

Would you like to join?
Would you like to be informed about current projects?
We will gladly keep you up to date.

The team: we unite a diverse and long-standing experience

“Convinced that climate protection needs international action on the basis of equity and equality a group of energy and development experts, church leaders, and students from Germany, India, The Netherlands, Rwanda, South Africa, and Tanzania started discussions on how to implement international climate action by citizens worldwide in 2020.”

 

Together with “Wuppertal Institute”, “Bread for the World” and “United Evangelical Mission”, we discussed climate justice with representatives from both governments, companies, churches and non-profit organizations in Rwanda and Tanzania.
In addition, we wrote two feasibility studies that examined different ways of using renewable energies in Rwanda, Tanzania and South Africa. Based on this, we launched the “One Climate Fund Southern Africa” and the “One Climate Solar Homes Rwanda GbR”.

The latter one implemented together with United Evangelical Mission, Presbyterian Church of Rwanda, Anglican Church of Rwanda and Rural Development Interdiocesan Service a pilot project, serving 200 families in off-grid areas in Rwanda with solar-home-systems.

Eventually, and after many meetings and long discussions with NGOs, banks and other institutions concerning the issue of a broad citizen participation in international climate justice we arrived at the point where we said: We cannot leave this important issue to foreign institutions only. We have to take climate protection into our own hands; into the hands of all citizens. That led us, together with our Dutch friends from “Energie Samen”, to found a company where people are the owners and decide for themselves how to implement climate protection internationally.
This led to the decision to found the “1 Climate International Cooperative U.A.” under Dutch law.
The philosophy and the business concept were essentially derived from the findings of climate science and from the experiences that the founders had had in the organizations, listed below.
