# CO₂, energy, and team challenges

The **create event wizard** includes challenge presets beyond standard run/bike/step types. They set default sports, leaderboard columns, and team rules you can adjust later.

**Path:** Manager console → **Create event** → **Team**, **CO₂**, or **Energy** button

Internal keys: `team_ch`, `co2_ch`, `energy_ch` — see [Create event wizard](create-event-wizard.md).

## Team challenge (`team_ch`)

Team-first sports challenge — participants join **teams** and team standings are enabled from the start (`have_teams`, `have_teams_standings`).

| Default | Value |
|---------|--------|
| Sports | Walk, hike, nordic walk, run, orienteering |
| Teams | Required — team standings on |
| Scoring | Distance per sport |
| Access | Unlisted draft until you publish |

### Wizard team setup

On the external Easy Event Create form you can choose:

- **Organizer teams** (`Event Team = org`) — you enter comma-separated team names; participants pick from a required "Pick Team" question; only listed teams allowed (`only_private_teams`).
- **Participant teams** (`Event Team = participant`) — participants create or join teams freely; same sport defaults apply.

Configure team size caps and join rules later in [Challenge settings reference](challenge-settings-reference.md).

Participant guide: [Joining a team](../joining-events/joining-a-team.md).

## CO₂ challenge (`co2_ch`)

Tracks estimated **CO₂ savings** from active travel (walking, running, cycling) instead of driving.

| Default | Value |
|---------|--------|
| Challenge kind | `CO2_CHALLENGE` |
| Leaderboard columns | Rank, name, CO₂ total, CO₂ today |
| Sports | Walk, hike, nordic walk, run, orienteering, ride |
| Totals shown | Distance (other totals hidden vs standard challenges) |

Ideal for sustainability campaigns. Participants see CO₂ totals on **My result** and the public leaderboard.

## Energy challenge (`energy_ch`)

Scores participants on **energy** (calories converted to kWh) across all sport types.

| Default | Value |
|---------|--------|
| Sport scoring | Calories per activity (`ChallengeSport.KIND.CALORIES`) |
| Sports | All sport types enabled |
| Energy unit | `kwh` in challenge params |
| Totals | Distance, time, calories on result views |

Use for wellness programs emphasizing active energy burn rather than distance alone. Leaderboard ordering follows total calories/energy unless you change display settings.

## Shared wizard defaults

All three presets (and other wizard types) start with:

- **Unlisted** access until you share the event
- Registration open immediately through event end
- GPS activities expected (`should_have_gps`) except step variants
- 12-hour grace period after event end (`after_end_hours`)
- Default hero image for the event type

## After creation

1. Adjust dates, access, and pricing in settings
2. For team events — review teams and the team picker question
3. Publish via [Share your event (Easy Access)](share-your-event-easy-access.md)
4. Monitor [Challenge dashboard analytics](challenge-dashboard-analytics.md)
