#3 Webinar: Sustainability expert circle - Best practices Banking

We at Global Changer believe that existing challenges in the climate crisis cannot be solved with the same mindset that created them.


To look at this challenge for our planet and future generations from the perspective of a desirable future, we have created a network of experts. Under the name "Global Changer" we are creating a space for best practices in sustainability, innovative solutions and climate positivity in companies.


The third Global Changer webinar included practical impulse lectures on sustainability in the real estate industry.
