Tl;dr

• We are launching a sports-based fundraiser for effective climate charities called the World Climate Relay.
• The goal is to reach people who care about climate but are outside the EA bubble, especially the outdoors community, and introduce them to effective giving.
• Participants take on a human-powered challenge and fundraise for the Giving Green Fund.
• From 5-12 June 2026, we aim to move together around the Earth while raising $100,000 for effective climate action.

Why this initiative, and why climate

This initiative grew out of a very concrete opportunity. One of our co-founders, Jennifer, has also co-founded Mieux Donner, and brings both experience launching a successful effective giving organization and an existing network in a values-aligned community. At the same time, Jennifer is a mountain guide and has deep connections in the outdoors community. In that space, climate change comes up constantly. People see it around them, are worried, and want to do something meaningful. At the same time, most of them are not familiar with effective giving and would not otherwise engage with effective altruism.

This creates a strong counterfactual case. Many outdoors-oriented people already care about impact, but they are not aware of frameworks like cost-effectiveness, evidence-based charity selection, or organizations like Giving Green. We see this as a chance to reach people who are already motivated, but currently donating or acting in less effective ways, or not at all.

Climate is not the most prioritized EA cause area, but it has broad consensus and high emotional salience, especially in outdoors communities. By using climate as an entry point, and framing action through a fun, physical challenge, we think we can introduce effective giving to people who would not respond to a more typical EA pitch.

Our aim is not just to raise money, but to help effective giving break out of the EA bubble and reach a wider audience that already wants to make a difference.

What we are doing

We are organizing a global, human-powered fundraising challenge called the World Climate Relay, taking place during the week of June 5–12, 2026. We aim to be inclusive to all nationalities, backgrounds, and physical abilities. It’s called a relay because we actively encourage participants to share the challenge and pass it on to others, with the goal of creating a growing network and building a global movement.

The challenge

Before the week of the Relay, participants:

• Choose a human-powered challenge of their choice, setting any distance or goal that feels meaningful and realistic to them (for example: walk 10k steps a day, run a marathon, cycle 50km, climb 1000m, etc.).
• Sign up and create a personal fundraising page, where they or other people can donate towards a goal they set.
• Invite friends, family, or colleagues to take part in the challenge or donate.

During the week of the Relay, participants track their activity using the Strava app or manual tracking, and we aim to “move together” globally during that week.

Our 2026 goals

• Raise $100,000 for effective climate charities.
• Have participants from 50 different countries.
• Cover a collective distance of 40,075 km (the circumference of the Earth).

Our setup and outreach strategy

The fundraiser is hosted on our website, built through the Raisely platform. All donations are routed directly to the Giving Green Fund. The platform takes no cut from donations; donors can optionally cover platform costs, but this is not required.

Alongside the challenge, we explain what effective climate action looks like in practice and what kinds of interventions Giving Green supports. The aim is to make effective climate action feel tangible, social, and energizing, while staying grounded in evidence.

Our outreach strategy prioritizes broad engagement over deep technical detail. We plan most (~80%) external-facing content to focus on excitement and social momentum, with educational material available for those who want to dig deeper. We’re making this tradeoff to lower the barrier to entry for people outside the EA community, while still providing transparent access to the reasoning behind our charity recommendations.

How you can help

Our biggest need right now

We just launched our website in November, and gaining traction quickly on social media and Google is challenging. This is why, in our first year, we’re focusing on connecting with people who have large, engaged audiences.

Right now, our biggest need, and the way you can help most, is through warm introductions to companies and ambassadors. If you know a company or influencer who might be interested in getting involved and sharing the relay with their audience, we’d be so grateful if you could connect us.

You can get in touch at info@worldclimaterelay.org.

Other ways you can support us
