Meet Global Changer

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.

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. Let’s collectively change the way the world does business!
