Pledge for the Planet
Our impact

Individual action, collective impact

One pledge can feel small. Thousands of them across clubs, schools, workplaces and races add up to something big. Here's what that looks like, and how we count it.

Because saving the planet is a team sport.

Why collective action matters

One action is a start. Community is how it grows.

A reusable cup won't fix climate change on its own. We know that.

But one person rubs off on a mate, a few mates shift a team, and a whole club can stack up thousands of actions. That's where it gets big.

Progress over perfection

We're not after perfect environmentalists. Just the next action you can take, tracked, and then the one after that.

Saving the planet is a team sport

Climate action can feel lonely. It feels very different when your teammates are in it too. Missions, check-ins, photos and leaderboards make it social.

Protect the places we play

We run, ride, swim and play through the places we want to protect. Linking action to sport makes it about the parks, trails and beaches you already love.

Methodology

How we measure impact

Impact data should help people understand what changed, not simply produce the biggest possible number.

We count participation, action and movement separately, then show them side by side.

What our numbers mean

We use several measures to understand how people are taking part.

Measure
What it tells us
Pledges made
The environmental actions people have committed to
Check-ins
Actions people have reported completing, often with a photo
Pledge points

Our three impact units
co2

CO₂e

Carbon dioxide equivalent. It puts the greenhouse gases an action avoids into one comparable number, shown in kilograms each year.

Example pledges
Your pledge
Commute under your own steam
Daily
730 kg
est. CO₂e saved a year
Collective counter
2.5M kg
est. CO₂e reduced by the community
delete

Waste

The number of pieces kept out of landfill each year, by avoiding, reusing, repairing, donating or diverting them.

Example pledges
Your pledge
Reusable bottles always
Daily
577 pieces
est. waste avoided a year
Collective counter
1.5M
est. waste pieces reduced by the community

Systems change

Actions that push for wider change rather than cutting your own footprint, such as writing to your MP, moving your money or organising an event. Each one counts as one action.

The detail
Estimating environmental impact

Where possible, each environmental pledge is assigned an estimated CO₂e or waste value, or counted as an action driving systems change.

The calculation considers:

The action being taken
The pledge frequency
The length of the commitment
The accountability completed
The baseline or alternative behaviour
Relevant emissions, waste or lifecycle data
The assumptions required to make the estimate
Completed and tracked impact

Only counts once you've checked in. A planning pledge counts as participation, with no CO₂e until the action actually happens.

Projected or potential impact

What could happen if you keep it up for your full timeframe. Always labelled separately, and never counted as done.

Equivalents such as cars and skips

Cars and skips make big numbers easier to picture. We always show the real unit first.

Sport and sustainability

Like a team distance, but for the planet

Pledge tracks environmental action and movement alongside one another because both demonstrate what happens when individuals contribute to a team.

Global framework

Connected to the UN Sustainable Development Goals

Every pledge maps to one or more UN Sustainable Development Goals, so you can see how a small action links to global priorities. You'll find it on each pledge page.
