All Eyes on New York

It’s a busy week in New York as both the 80th Session of the United Nations General Assembly (UNGA80) High-level Week and Climate Week NYC kicked off.

“UNGA conversations are vital for recalibrating the system and identifying the actors who can push global priorities forward,” says Lynn Wagner, IISD’s Senior Director of International Environmental Governance, highlighting the key issues to watch. In a Q&A with Lynn, we discuss the UN at 80, the Secretary-General's UN80 Initiative, and challenges for multilateralism.

If you’re at Climate Week NYC, don't miss today’s session on what the disruption and uncertainty caused by new trade barriers could mean for climate action and green trade. Our trade and green transition expert, Ieva Baršauskaitė, will join the discussion at Climate Group’s panel, “What’s Next for Green Trade in an Evolving Global Landscape?”

If you’re following the conversation online, check out yesterday’s UNGA80 virtual side event, co-hosted with UN University Centre for Policy and Research, on Beyond GDP—the push to reorient how societies measure success by placing well-being, sustainability, and resilience at the core of decision making.

Public Money, Public Value: The European Union’s Public Procurement Directive review explained

Oil Majors Sue Dutch Government: How could it have been avoided?

Reform is urgently needed—sign up to our webinar series with ClientEarth where we’ll unpack how.
