A global crisis demands local leadership—everywhere.

Today, we are thrilled to announce the Climate Week Network: a global platform and network that helps people discover Climate Weeks nearby — and helps organizers launch new Climate Weeks in their own cities.

The Climate Week Network exists to equip, connect, and amplify local organizers so no one starts from scratch. Our mission: bring Climate Week to every city.

Launching with 20+ cities

We’re launching with real momentum. 20+ cities are already on the platform—some with dates set, others actively recruiting co-organizers, partners, and sponsors.

  • Up first — San Diego Climate Week (Oct 1–8)

  • Up next — Mexico City Climate Week

  • Explore 20+ upcoming Climate Weeks in cities across the globe that are being planned, and we encourage you to get involved — or propose a Climate Week in your own city.

Bring Climate Week to your city

We aim to support both new launches and existing Climate Weeks worldwide. We provide infrastructure and amplification so local leaders can focus on programming, partnerships, and community.

  • Amplification — 150k+ newsletter reach, 10k+ climate organizations in our network, 1M+ annual site visitors, and shared press

  • Calendar infrastructure and tech — customizable, flexible, and powerful tools

  • Playbooks & templates — playbooks and templates for outreach, sponsor kits, and more

  • Community — connect and collaborate with a global community of Climate Week organizers

  • Sponsor & partner networks — warm intros for city-specific and multi-city activations

  • Volunteer network — build your local Climate Week team with support of our global network of volunteers

Why this matters now

Nearly a decade after Paris, we’re on track to cross 1.5°C—and headed toward 2°C+. The convenings meant to shape climate policy are often inaccessible, centralized, and influenced by entrenched interests. Meanwhile, communities already facing smoke, heat, floods, and rising costs need practical local ways to act: a distributed, community-led approach that’s scalable, replicable, and open to the public.

Climate Weeks are that approach—and the model is proven. In just three years, our community at Climatebase grew San Francisco Climate Week to 25,000+ participants across 650+ events, with 3,000+ organizations participating—featuring leaders including Al Gore and hundreds more. As SF Climate Week has grown, organizers worldwide have asked for our guidance, audience, network, and tools to launch their own.

The Climate Week Network is our answer. We package promotion, playbooks, tools, and guidance so cities launch Climate Weeks faster and more effectively to deliver the impact that counts:

  • Stronger local policy that pushes national and international progress

  • More people engaged in climate action and working in climate

  • More collaborations that accelerate climate solutions

Ways to get involved

Whether you’re an individual, a local government, a nonprofit, or a company, there’s a role for you. Through the Network, organizations can engage across multiple cities, and we’ll facilitate those connections to make participation seamless and impactful.

  • Who is behind the Climate Week Network?
    Climate Week Network is a philanthropically supported initiative led by Climatebase.org and fiscally sponsored by Grounded.org (a 501(c)(3) public charity), enabling tax-deductible donations.

  • How long does it take to plan a Climate Week?
    Timelines vary; we provide playbooks and mentorship to accelerate planning. Many first-time Climate Weeks plan for ~3–6 months.


Climate Week, everywhere.

When cities host Climate Weeks, policy changes, capital moves, local leaders emerge, and communities take center stage while connecting with the global movement. And each new Climate Week sparks collaborations, builds on-ramps to act, sustains momentum, and accelerates solutions.

In the next 12 months, we aim to help launch and grow dozens of Climate Weeks around the world—on the path to every major city.

We invite you to get involved.
