Meet and greet
with Global Changer

Climate change is a hard-to-grasp topic. We make it more tangible and help companies take the proper steps to move towards a net zero society. By this, we thrive on creating a liveable environment for present and future generations. 


Global Changer is a Berlin-based technology company founded by entrepreneurs and innovators who couldn’t look away from the current state and therefore wanted to take collective action. We actively work with SMEs and large corporations along their climate journey and help them to reduce and remove their CO2e emissions by 2030.
