Commute Grand Prix — NY Climate Week 2026: official rules

Every year, the world gathers in New York to talk about climate. This year, we're moving. The Commute Grand Prix turns the gap between talking and doing into a week of action: from 20 to 27 September 2026, anyone, anywhere, can take part for a US$ 10 registration fee — download the Ecomiles app, register in-app, log your daily commute, and watch your verified emissions savings accumulate on a live global leaderboard, as an individual and on behalf of your employer. Employers can sponsor rewards for their own teams at no cost to participants.

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: Commute Grand Prix — NY Climate Week 2026 edition
• Organizer: Ecomilhas Tecnologia Ltda (Ecomiles), with subsidiaries in Delaware (USA) and Barcelona (Spain)
• Where: inside the Ecomiles app, worldwide
• Registration fee: US$ 10 per participant, paid once in the Ecomiles app when joining the Grand Prix (in-app purchase). No subscription required.

2. Dates

• Start: 20 September 2026, 00:00 (participant's local time)
• End: 27 September 2026, 23:59 (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 sponsored rewards.
• 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 and pay the US$ 10 registration fee (in-app purchase, charged in your local currency equivalent by the App Store or Google Play).
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, carpool, or drive an ethanol or electric vehicle. 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 week.

5. What counts

• Eligible modes are the low-carbon modes already recognized by the Ecomiles app: walking, cycling, public transport, carpooling, ethanol-fueled vehicles and electric vehicles.
• 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 global and updated live in the app. Ecomiles may also publish highlights on its website and social channels during NY Climate Week.
• 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.

7. Employers and sponsored rewards

• Any employer can appear in the leaderboard as soon as one of its employees selects it in the app — no contract required for the Grand Prix.
• 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; they 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 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, the LGPD 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. Participants can change their display name at any time.

10. General terms

• Taking part in the Grand Prix means accepting these rules and the Ecomiles Terms of Use.
• Refunds: the registration fee is non-refundable once the campaign window has started, except where required by law or if Ecomiles cancels the campaign — in which case it will be refunded in full, as set out in the Ecomiles Refund Policy.
• 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.
