350.org is an international environmental organization building a global grassroots movement to solve the climate crisis. Their campaigns focus on ending the use of fossil fuels, divesting from fossil fuel companies, and promoting community-led renewable energy solutions. The '350' in their name refers to 350 parts per million (ppm) — what was once considered the safe concentration of carbon dioxide in the atmosphere to maintain a livable planet.
Serves as a central administrative and coordination hub for global operations, strategy development, fundraising, communications, and US-based campaign activities.
The office is located within Industry City, a repurposed historic industrial complex. The space is designed to be functional and collaborative, supporting the organization's dynamic work environment rather than focusing on architectural extravagance.
Passionate, mission-driven, collaborative, and activist-oriented. Staff are deeply committed to climate justice, grassroots organizing, and creating systemic change. The environment fosters innovation and rapid response to global events.
The Brooklyn location places 350.org within a vibrant hub of innovation, activism, and progressive movements in New York City, facilitating networking, talent acquisition, and global connectivity.
350.org supports an extensive global network of grassroots organizers, local groups, and activists in over 188 countries. Key global functions include coordinating international campaigns (like fossil fuel divestment and calls for a Fossil Fuel Non-Proliferation Treaty), providing resources and training to local activists, spearheading digital organizing and mobilization, international communications and media outreach, policy advocacy at global forums, and fostering a diverse, equitable, and inclusive worldwide movement for climate justice.
