Grand Prix Bcombinator Sustainable Mobility - Bizkaia Edition

After New York and Barcelona, the Grand Prix comes to Bizkaia. Professionals and teams compete with their daily commute: every trip on foot, by bike, by public transport or by carpool earns points in the Ecomiles app, GPS-verified. Registration happens directly in the app and you can take part from anywhere. Dates and registration terms will be announced in the app and on this page.

This edition is run in partnership with Bcombinator, as part of its Bizkaia program. When the campaign ends, we share the final leaderboard, the awards and the CO₂e avoided in the app and on this page.

This page is the official rulebook of the campaign. Any update to the rules will be recorded here, with the date of the change.

1. The campaign

• Name: Grand Prix Bcombinator Sustainable Mobility, Bizkaia Edition
• Organizer: Ecomilhas Tecnologia Ltda (Ecomiles), with subsidiaries in Delaware (USA) and Barcelona (Spain), in partnership with Bcombinator
• Where: inside the Ecomiles app
• Registration: in the app, from the campaign banner

2. Dates

• Start and end: to be announced in the app and on this page. The window runs from 00:00 on the first day to 23:59 on the last, in the participant's local time.
• Only trips completed and verified within this window count toward the Grand Prix leaderboard.
• Trips logged before or after the window still earn ecomiles normally in the app, but do not enter the Grand Prix ranking.

3. Who can take part

• Anyone, anywhere in the world, with the Ecomiles app installed (iOS or Android) and an active account.
• Participation is individual. Each participant may also compete on behalf of one employer, selected in the app.
• Employees of Ecomiles and their immediate family may use the app during the campaign but are not eligible for prizes.
• Participants must be of legal age to hold an account under the Ecomiles Terms of Use.

4. How to participate

1. Download the Ecomiles app on the App Store or Google Play and create your account (or sign in).
2. Join the Grand Prix from the campaign banner in the app. Registration happens right there, with no external link.
3. Select your employer (optional) so that your verified savings also count for your company's team.
4. Commute as usual. Walk, cycle, take public transport or carpool. The app detects and saves your trips automatically: no forms, no photos, no self-declaration.
5. Follow the leaderboard in the app, updated live throughout the campaign.

5. What counts

• Eligible modes are the low-carbon modes already recognized by the Ecomiles app.
• Every trip is GPS-verified by the Ecomiles methodology, which is based on the GHG Protocol and holds limited assurance from an independent third party (KPMG).
• Savings are measured in kilograms of CO₂e avoided compared with the baseline of a conventional combustion car for the same route. In the app, 1 ecomile = 1 kg of CO₂e avoided.
• Trips that fail verification (implausible speed, inconsistent route, duplicated or manipulated location data) are not counted.

6. Scoring and leaderboard

• Individual ranking: the sum of verified CO₂e avoided by the participant during the campaign window.
• Employer ranking: the sum of verified CO₂e avoided by all participants who selected that employer during the window.
• The leaderboard is updated live in the app. Ecomiles may also publish highlights on its website and social channels during the campaign.
• Ties are broken by the earliest timestamp at which the tied total was reached.
• Final results are consolidated after the window closes, once all pending verifications are processed, and announced in the app and on this page.

7. Employers and sponsored rewards

• Any employer can appear in the leaderboard as soon as one of its employees selects it in the app, with no contract required.
• Employers may choose to sponsor rewards for their own teams (for example, redeemable ecomiles or prizes for their top participants). Sponsored rewards are defined and funded by each employer and are always free of charge for participants.
• Employers interested in sponsoring rewards, receiving their team's verified Scope 3 data, or running the Grand Prix as an internal program ahead of the PMST can contact us at contato@ecomilhas.app.

8. Fair play

• One account per person. Duplicate accounts, shared devices or automated logging are not allowed.
• Any attempt to manipulate location data, simulate trips, or otherwise game the verification will lead to the removal of the affected trips and, at Ecomiles' discretion, disqualification from the campaign.
• Ecomiles' anti-fraud validation applies to every trip, as described in our Security & Methodology page.

9. Privacy

• Ecomiles processes location data only to verify trips and calculate avoided emissions, in accordance with our Privacy Policy and the GDPR.
• Employers see aggregated results for their team; they never receive an individual's real-time location.
• Leaderboards show the participant's display name as configured in the app, which can be changed at any time.

10. General terms

• Taking part in the Grand Prix means accepting these rules and the Ecomiles Terms of Use.
• Ecomiles may adjust dates, scoring or rules if needed to preserve fairness or comply with the law; any change will be published on this page and communicated in the app.
• Questions about the campaign: contato@ecomilhas.app.
