Is there one ticket for Climate Week NYC?

No. Climate Week is a calendar of separately run events, and each one sets its own admission — some open to anyone, some by registration, some invitation only.

Who organises Climate Week NYC?

The Climate Group, an international non-profit, which sets the dates and the main programme while other organisations register their own events under it.

Climate Week NYC 2026 — New York 42

For one week in September the city carries a second conference on top of itself, and most of it is not in one building. Climate Week NYC is a calendar rather than a venue: hundreds of separately run events across Manhattan and Brooklyn, held under one name and one set of dates.

Climate Week NYC 2026 dates

September 20 to September 27, 2026, across New York City.

Who runs Climate Week NYC

The Climate Group, an international non-profit. It sets the dates and the main programme; the rest of the calendar is filled by organisations registering their own events under it.

The scale

The organisers put attendance at over 100,000 people a year, which makes it the largest annual gathering of its kind in the city.

What is on the 2026 calendar

Among the featured events: investor and family-office summits, clean energy trade and the grid, methane reduction, the circular economy and aluminium recycling, and the electricity demand of AI.

Getting into Climate Week events

There is no single ticket. Each event on the calendar sets its own terms — some open, some by registration, some invitation only — so the calendar entry is the thing to read, not the week.

The mistake is treating it as a conference you attend. There is no badge that opens the week: the main programme is a small share of it, and the hundreds of events around it are run by whoever registered them, each with its own door policy. What that means in practice is that the useful planning happens on the calendar page a fortnight out, when the open events are still taking registrations — by the week itself the ones worth going to are full. The second thing worth knowing is what it does to the city: it runs alongside the UN General Assembly, and midtown east of Fifth is slower all week.
