New York Road Runners (NYRR) is a nonprofit with the aim of building healthier lives and stronger communities through the transformative power of running, which includes doing our part to ensure future generations have access to clean air, green spaces, and a healthy world in which to run.

In 2024, NYRR made history as the first major marathon to introduce a guaranteed race entry method that supports sustainability initiatives, by offering runners the opportunity to join NYRR’s Team for Climate and fundraise to offset or reduce carbon emissions to help contribute to NYRR’s sustainability journey.

NYRR has partnered with Anew Climate, a global climate solutions leader, and committed to use a portion of the funds raised by NYRR Team for Climate to purchase verified carbon credits for improved forest management projects, a practice known as carbon offsetting. NYRR has also committed to using a portion of the funds raised by NYRR Team for Climate for projects within NYRR that reduce the total emissions generated within NYRR’s events and operations, a practice known as carbon insetting.
