At this week?s global environmental gathering in Copenhagen, cities aim to set the agenda September saw climate strikes, a UN Summit, and impassioned speeches from teen activist Greta Thunberg?but despite the attention paid to the crucial issue of climate change, no transformative agreements were made.
?The climate emergency is a race we are losing, but it is a race we can win,? said the UN Secretary-General António Guterres, who convened the Summit that concluded with mixed results.
This week, a gathering of city leaders at the C40 Mayors Summit in Copenhagen, Denmark, hopes to accomplish more, seeking to announce initiatives, plans, and agreements that will make a significant dent in emissions. By bringing together mayors, business executives, scientists, leaders of the Youth Climate Strike, and elected officials, such as Alexandria Ocasio-Cortez, who is giving a keynote address on Wednesday, and Secretary General Gutteres, the gathering reflects what organizers see as the power of cities.
