Climate Week NYC: relentless determination

26th September 2023 7 min read

That’s a wrap for this year’s Climate Week NYC, run by Climate Group in partnership with the UN General Assembly and the City of New York – and what a week it was. By far the biggest ever with almost 600 events across the week, and an atmosphere of relentless determination throughout the Opening Ceremony, The Hub Live and the events that were held across the five boroughs of New York.

Climate Week NYC took place against a backdrop of the increasing impacts of the climate crisis being felt around the world through extreme heat, wildfires and devastating flooding, and vested interests continuing to slow down climate progress. While we have seen a significant leap forward in the past year, we know that the speed and scale of change needed isn’t happening. Just the week after Climate Week NYC happened, the International Energy Agency (IEA) came out with an update on its Net Zero Roadmap: we need to triple our renewables and double our energy efficiency to reduce fossil fuel use by two thirds for 2035. 

So no, we’re not there yet. Despite all this, the sense of optimism and relentless determination in the face of this challenge was encapsulated by this year’s theme We Can. We Will. We came away with new ideas, connections and energized to keep pushing for climate action. So, let’s quickly run through some of the highlights, major announcements, and impressive speaker moments.
