Setting the Stage: What Is Climate Week & Why It Matters More Than Ever
Over the years, it’s grown from a few dozen sessions to a sprawling week-long convergence of business leaders, policymakers, nonprofits, innovators, and climate activists. In 2023, for example, Climate Week NYC featured over 580 events, drew 6,500 attendees from nearly 100 countries, and claimed a media reach of 6.9 billion.
Also worth noting: Climate Week sits at a strategic intersection. It overlaps with the UN General Assembly, which means many heads of state and influential global leaders are already in New York. This adds leverage: discussions aren’t just theoretical — they dovetail with diplomatic, financial, and policy levers.
