“Proud that cities are working together and speaking with one voice”. Mayor Juergen Nimptsch, Bonn, presenting carbonn Climate Registry on UN Radio

But at the same time, we should collectively develop a new culture of sustainability in order to reach a 1.5 C compatible world under the Paris Agreement and deliver other sustainable development goals.
