Meet Global Changer

Global Changer is a Berlin based technology company that was founded in 2020 by entrepreneurs and innovators who couldn’t look away at the current state and had to take collective action.

In the next decade of action, we actively work with small and medium enterprises (SMEs) and large corporations along their climate journey and help them to reduce and remove their CO2 emissions by 2030.

Climate change is a hard to grasp topic. We want to make it more tangible and and help companies to take the right steps.

We only have one planet and currently, we are not treating it well to sustain wildlife, our fellow species and all other wonders of the world.

Let’s change it, globally together!
