Pledge for the Planet
About Pledge for the Planet

From “I’m just one person” to “I’m part of a team”

We’re an environmental charity using sport and community spirit to get people taking real climate action.

Because climate action feels more possible when we do it together.

Our story

It started on a run

Alice running the Edinburgh Marathon in 2019

In 2019, Pledge founder Alice Kendall was training for the Edinburgh Marathon and listening to Turning the Tide on Plastic.

Like most runners, Alice had thought about fundraising. But endorphins, exhaustion and a fair dose of climate anxiety sparked a different idea.

What if support didn’t have to be money? What if friends and family could support a challenge by making an environmental pledge instead?

She wrote 16 practical climate actions people could choose from. Pledges became a new kind of currency, and one runner’s challenge turned into collective action.

The idea of action-raising, and Pledge for the Planet, was born.

Alice moved to Australia in 2020 and kept building. Pledge officially launched in 2021 with the first 48 Hour Mission.

Those 16 pledges have grown into a community of Pledgends taking action through clubs, schools, workplaces and races, across Australia and beyond.

The idea

A marathon-training run and one question: what if people could back a challenge with action instead of cash?

2020

A new home

Alice moved to Australia and rebuilt the idea around sport and community.

2021

Pledge launches

The first 48 Hour Mission brought movement, pledges and a bit of friendly competition together.

2022

The community grows

The second Mission inspired 657 pledges. Our first Clothes Swap saved 250 items (102 kg) from landfill.

Pledge also began creating new ways for people to take action together, including its first Clothes Swap, where 250 items and 102 kilograms of clothing were swapped rather than wasted.

2023

The Mission takes off

24 teams and 400+ people made 1,263 pledges and moved 21,002 km, with a live leaderboard keeping score.

Together, the community made 1,263 environmental pledges and moved 21,002 kilometres across walking, running, cycling and swimming.

A live leaderboard made the action, activity and friendly competition visible throughout the Mission.

2024

HATCH Taronga

Pledge joined Taronga’s HATCH Accelerator to grow the organisation, platform and impact model.

2025

New programs and partnerships

The fifth 48 Hour Mission, and Run the Talk launched with the TCS Sydney Marathon.

2026

Five years of collective action

Five years in, with Kickstart Mission, Planet PB, event activations and Pledge Schools.

The idea hasn’t changed: give people a practical action, bring them together and show them what they can do.

What guides us
Our purpose

Ignite community spirit to power collective climate action

Making climate action feel practical, positive and possible, especially together.

Our vision

A world where every community is moving together to protect the planet and the places we play

Climate action as part of everyday life, backed by the people around us.

Our mission

Get people moving to protect the places we play

Sport, movement and simple pledges that build momentum for bigger change.

Our approach

Why sport, community and climate action belong together

We’ve learnt this first-hand: active communities get stuff done. They set goals, follow a plan, track results, back their teammates and keep going when it’s hard.

Active people are doers

Runners, riders, swimmers and walkers already chase goals. We point that mindset at the planet.

Community creates accountability

It’s easier to try something new when your teammates are doing it too. Check-ins, photos and leaderboards keep it visible.

Movement connects us with place

We run, ride and swim through the places we want to protect. That makes climate action personal.

Collective action changes the story

One pledge feels small. Thousands across a community show what’s possible.

Progress over perfection, always.

Our Theory of Change

How we catalyse impact

1

Engage

Meet people through sport and movement, things they already love.

2

Pledge

Give them simple actions that fit everyday life.

3

Act

Missions, teammates and friendly competition turn intention into action.

4

Track

Check-ins, photos and leaderboards make progress and impact visible.

5

Multiply

Clubs, schools, workplaces and events bring more people in.

6

Impact

Lasting habits, less emissions and waste, stronger communities, and climate action as the norm.
