The Green Runners

Breaking down a runner's carbon footprint

The Green Runners are a community of environmentally conscious runners who have developed a clear approach to reducing carbon emissions within the running community.

Formed after COP26, this grassroots movement has created practical frameworks and resources to help runners understand and reduce their environmental impact while building a supportive community around sustainable practices.

Through this approach to environmental action, The Green Runners demonstrate that sporting communities can drive meaningful climate action by making sustainability accessible, relevant and achievable for their members.

The Green Runners

Why have they taken action?

While running is often perceived as a low-impact sport, the community recognised that significant carbon emissions stem from various aspects of running culture.

For example, on average over 90% of mass-participation events' carbon footprint comes from participant travel, with additional impacts from equipment consumption, nutrition choices and lack of environmental awareness.

The challenge was to translate complex carbon footprinting concepts into actionable, runner-focused guidance that the entire community could understand and implement.

How have they done it?

  • Breaking down complex concepts

    The Green Runners developed a four-pillar framework that transforms confusing environmental jargon into clear, actionable areas:

    1. How we travel

    Addressing the largest impact area by encouraging sustainable transport to running events, recognising that air travel and solo car journeys have the most significant environmental cost.

    2. How we kit up

    Tackling overconsumption of and waste from running gear by promoting sustainable purchasing and reusing, repairing and opting for second-hand kit, where possible, rather than acquiring new products.

    3. How we fuel

    Encouraging plant-based nutrition and reducing single-use plastics in running nutrition, helping members understand the environmental impact of dietary choices.

    4. How we speak out

    Empowering members to become environmental advocates, recognising that collective voices create greater impact than individual efforts.

    By translating complex environmental concepts into familiar running terminology, The Green Runners make sustainability relevant and understandable to their target community.

    The four-pillar framework provides clear structure without overwhelming participants.

  • Building a supportive and inclusive community

    Progressive commitment model

    The Green Runners encourage new members to make a pledge under each pillar, making one pledge at a minimum, acknowledging that "progress, not perfection" drives meaningful change.

    This approach removes barriers to participation and allows individuals to build confidence before expanding their commitments.

    Local meetups and knowledge sharing

    Regular in-person gatherings foster a sense of community within The Green Runners and enable localised knowledge sharing on how to make tangible lifestyle changes (e.g. the best second-hand shop in your area, or a network of friends to ride-share).

    So far, active meetups in Nottingham and Bristol have been really successful, and there is an ambition to expand regional networks across the UK and beyond.

    Educational resources

    Online materials support member understanding of each pillar's environmental impact and provide practical guidance for making carbon reductions.

    The Green Runners provide concrete actions and resources that members can immediately implement, from transport choices to equipment purchases to dietary changes.

    Representation and advocacy

    Members can purchase badges made from upcycled race t-shirts, creating conversation starters and visible commitment to environmental action while keeping materials out of landfill.

    Spreading the message

    The Green Runners attend running events to educate participants about carbon impacts and demonstrate that environmental action can be integrated seamlessly into running culture.

    This outreach approach extends their influence beyond direct membership.

  • Working on a 'Greener Races' scheme to support event organisers to become more sustainable.

Top tips

Simplify complex issues

Environmental challenges can seem overwhelming, but breaking them into manageable, sport-specific categories makes action achievable and relevant.

Start small, build momentum

Requiring only one initial commitment encourages participation and allows individuals to build confidence before expanding their environmental efforts.

Local networks drive impact

In-person connections and regional knowledge sharing create stronger, more sustainable community engagement than purely digital approaches.

Use existing passion

Leveraging members' existing love of running provides a powerful foundation for environmental advocacy, making sustainability personally relevant rather than abstract.
