Frequently asked questions

Option 1: Joining a challenge with an invitation link or QR code

To join the challenge, simply use your mobile device to click on the invitation link or scan the QR Code that your organization’s admin has shared.
Once you are redirected to the challenge page, click on the “Join”

Option 2: Joining a challenge from the app

You can just navigate to the Challenges tab in the Deedster app and check out what challenges are available to join.
Once you find a challenge you want to join, click the “Join” button.

The duration varies from one challenge to another, depending on the content, but a challenge usually lasts between two and three weeks. 

The challenges content is available as long as your company license runs. You can find ended challenges under the challenge tab, in the past challenges section.

No. Quizzes do not award points. Points are earned only by completing Deeds, ensuring that the scoring reflects real actions taken during the challenge.

The challenge content is available as long as your organization’s license runs. Late joiners can still access the challenge’s quizzes and Deeds, but the leaderboard is locked once the competition ends.

You can find ended challenges on the Challenge tab, under the Past challenges section.

The progress bar on the journey map shows the percentage of correct quiz answers. It reflects how well you performed on the quizzes.

Participants who achieve 100% correct answers earn the Master badge.

No worries! Focus on the active members — they drive the team’s progress. If some can’t participate, kindly ask them to leave the team so their low scores won’t affect your team’s results.

Teams on the bench are teams that have fewer than 3 participants. These teams remain visible in the app but don’t appear on the leaderboard or compete in the challenge. This ensures the competition remains fair and balanced, since very small teams could otherwise have an advantage (or disadvantage) when averaging scores.

The leaderboard is based on the average number of Deeds completed per team member, not the total number of Deeds. This means that both small and large teams compete on equal terms.

There is no member limit by default, but we recommend that teams have between 5 and 20 members. While setting up the challenge, the admin can choose to set a maximum limit. That might be the case in your organization.

Teams with fewer than 3 members are placed on the bench and don’t participate in the competition. So make sure that your team has more than 3 members.

You can invite a colleague to join you team by clicking on the invite button in the top right corner of the journey map. The invited participant will receive a unique team code and link to join your team.

A Deed is an action you can take for the planet, or to learn more about sustainability. Each completed Deed earns 1 point and contributes to the leaderboard score.

New Deeds are unlocked by completing quizzes included in the challenge. 

Open the Deed, follow the instructions, and tap “Mark as done” once completed. Some Deeds are quick actions, while others encourage reflection or real-life behavior change.

Most Deeds are one-time actions. Some can be saved as Habits, allowing participants to repeat them and build long-term behavior change. Habits can only be marked as done for the current and previous day.

Yes. Each completed Deed or Habit grants 1 point, ensuring fairness and emphasizing participation rather than complexity.

Only Habits can be marked for today or yesterday. Regular Deeds should be marked immediately after completion to accurately track progress and team scores.

Deeds can be skipped without penalty. Teams continue earning points from other completed Deeds, maintaining engagement and progress.

Deeds are tailored to individual profiles and lifestyles. For example, a meat eater may receive a “Try a vegetarian lunch” Deed, while a vegetarian may receive a “Try a vegan lunch” one. Personalization ensures that all actions are meaningful and achievable.

The leaderboard is hidden during the last 48 hours of the challenge to keep the suspense until the finish line! You can still complete deeds and earn points as usual — everything is tracked in the background. Once the challenge is over, the leaderboard will be revealed.

The team score is the average number of deeds done per member, so teams of different sizes can compete fairly.

Each completed deed earns 1 point. Some Deeds can become habits and be repeated daily. You can mark a habit as done only for today or yesterday — if you miss more than a day, you won’t get points for past days.

You can earn several types of badges that recognise learning, action, and progress throughout the challenge. These badges help highlight milestones and keep engagement high.

Challenge badge

The Challenge Badge is awarded when you complete the full quiz journey. It marks that all required stations and quizzes in the journey have been completed.

The Master Challenge Badge is awarded to participants who complete the entire quiz journey with 100% correct answers. It recognises full mastery of the educational content.

Milestones badge

Milestone Badges celebrate progress linked to meaningful climate action. You receive these badges when you:

• Complete a certain number of Deeds, or
• Reach specific CO₂e savings milestones.

Mission badge

The Mission Badge is awarded when you complete the Mission before its deadline. It rewards timely engagement.

The Deedster app itself does not include built-in rewards or prizes. However, organizers can choose to create their own rewards for challenge winners or for participants who earn specific badges. Check with your organization for rewards related to the challenge.

You can find the badges you’ve earned under your profile page.

The lifestyle footprint calculator estimates the environmental impact of your daily activities, such as commuting, travel, and energy use. It provides a personalized footprint based on science-based calculations, helping you understand where you can make a difference.

In the questionnaire, you provide basic information about your diet, commuting habits, travel, home energy use, and consumption habits. The calculator uses this data to generate an individualized footprint.

No. Your individual footprint is private and only visible to you. This keeps personal data secure while allowing participants to focus on their own progress.

No. Your organization admins do not see individual footprints. We only share aggregated and anonymized data for reporting and engagement insights, ensuring privacy while enabling meaningful analysis.

The footprint helps personalize Deeds and actions. It also provides context for tracking progress and understanding impact.

Yes. All footprint data is stored securely, and personal identifiers are protected. Reporting for admins is aggregated and anonymized, so individual data cannot be traced.

Yes. You can update your input if circumstances change — for example, switching commuting methods or updating home energy use — ensuring the footprint stays accurate over time.

No. Mission completion does not affect team scores or leaderboard rankings. Missions offer an additional way for participants to engage, allowing them to pursue individual achievement goals without disturbing the competitive balance of the challenge.

Missions can be found on the Home page.

A mission is a time-bound set of activities, such as completing one or several challenges and saving a certain amount of CO₂e, or completing a specific number of deeds. It can run in parallel with a challenge or extend over a longer period.

When you sign up as a user, you agree that we share your name and email address with the Deedster challenge organizer as per our Terms and Conditions. This way, the project team at the organization running a Deedster challenge will know who has joined and who might need help with onboarding.

What we won’t share, though, is your carbon footprint. This is because we think it’s essential that you, as a user, feel that your personal data is safe with us. Instead, we aggregate footprint data when it’s shared with your employer.

Users in your team can only see your profile picture, how many deeds you’ve done, and the CO2e-saving and/or Impact Points connected to those deeds from the leaderboard. We will not reveal your footprint to anyone in the app or to a third party.  

When using Deedster with a company license, you need to create an account with your email address (or by signing up with SSO) to enter a challenge that’s unique to your organization.

Unfortunately, no, Deedster challenges are only available from the Deedster mobile app.
