We come from the media, the energy industry, climate impact research and psychology -united to tackle the climate crisis.

Our CEO Felix Rodenjohann in autumn 2019 on the grounds of the UN Headquarters in New York.

Our CEO Felix Rodenjohann in the fall of 2019 on the grounds of the UN Headquarters in New York . There he spoke with heads of government, diplomats and developed the basis for ansvar2030 in the hotel room. In the meantime, Felix Rodenjohann has become an official Climate ambassador of the EU Commission.

What makes us special?

We have investigated why even in cities with a positive climate decision, emissions are not falling. We are now bringing together what needs to come together:

1. the climate crisis is a problem,

that concerns everyone and can therefore only be solved by everyone working together. We enable the cooperation of groups that previously had no points of contact - and thus increase the self-efficacy of the urban society.

2. knowledge alone does not lead to action.

It is important that we reach people in their hearts. As experienced filmmakers and storytellers, we therefore emphasize effective communication: Through emotional messages, we generate enthusiasm and community.

3. modern technology will not solve the climate crisis for us,

but it is an important tool. To meet the challenges ahead, we need transparent processes - and we also need to measure whether the measures we take are effective. Digital tools are indispensable for this.

That's how we increase the likelihood of getting into action.

"The energy transition is not failing because of money or technology, but because of human relationships."

So says Stephan Heinrich, partner and co-founder of ansvar. He brings the perspective of decades of management and CEO positions at energy companies. Although he is an energy economist and has already built several technology startups, he doesn't see the solution to the problem in technology. After all, everything from heat pumps to smart grids has long been available.
