Gibraltar's OTwo Active Challenge wrapped up with 926 participants walking, running, hiking and cycling a combined 84,501km over one month. Organizers estimate the effort avoided more than 14 tonnes of carbon dioxide, based on distances logged through Strava and manual entries. Winners were recognized in cycling and run, walk and hike categories, with clubs and local organizations also competing. Since the campaign began, the two Active Travel Month events have covered 172,501km with an estimated combined saving of 29.33 tonnes of CO2. The challenge is part of a broader push by Gibraltar's Department of the Environment, Heritage and Climate Change to make active travel a more routine part of daily life. Fundraising also raised £1,850 each for Diabetes Gibraltar and the Gibraltar Cardiac Association.

Nice to see a local campaign putting numbers on it. 84,500km is roughly 14 tonnes of avoided CO2, which works out to about 166g per km. That assumes people would have driven instead, so the real saving depends on mode substitution. Still, getting 926 people moving is a solid result for a month.

The 14 tonne estimate is the kind of number that needs a footnote. Did they assume every km replaced a car trip, or a mix of bus and car? Also curious if the Strava data is self-reported. Either way, the participation numbers are the more reliable story here.

Active travel is good, but the carbon math depends on what was displaced. If someone walked instead of taking a diesel bus, the saving is smaller than if they drove alone. The 166g/km figure seems roughly in line with average car emissions, so they might be assuming full car replacement. Fine as an estimate, just not a precise measurement.

A month-long challenge like this is more about habit formation than carbon accounting. The 29.33 tonnes across two years is tiny next to Gibraltar's overall footprint, but if it shifts commuting patterns permanently, the policy value is bigger. Worth tracking whether participation carries over after the campaign ends.

Good to see the Environment Department backing this. The certificates with estimated emissions avoided are a simple way to make the impact tangible. Would be better if they published the methodology behind the 14 tonne figure, but the campaign itself is easy to support.
