Estimates the CO₂ from flying hours in one or more aircraft types: one row for a pilot, several rows for a fleet (a school, club or operator). CO₂ = hours × the type’s kg of CO₂ per flight hour, from its fuel flow at about 75% power. Types match by name, ICAO type designator or page slug.

}For a company that uses the TrimCarbon offset API: how much CO₂ it has offset through the API, in total, in the last 30 days and by month, and its API access status. Needs the user to connect their TrimCarbon account.

}Shows one of the signed-in user’s TrimCarbon certificates: kg of CO₂, holder, dates, projects with their registries and retirement serial numbers, and links to the public certificate and its PDF. Takes the certificate number (TC-7K2M-9QXF-4HJD) that list_my_offsets returns. Needs the user to connect their TrimCarbon account.
| Argument | Type | Description |
|---|---|---|
| certificate* | string | Certificate number, such as TC-7K2M-9QXF-4HJD |

}Shows how much CO₂ the signed-in user has offset with TrimCarbon: the total, what is still being processed, by source (one-time, subscription, offset API), by year, and the projects funded. Needs the user to connect their TrimCarbon account.

}Opens a card where the user picks a logbook export from ForeFlight, Garmin Pilot or LogTen. The card reads the file on the user’s device, uploads nothing, and shows the flight hours and CO₂ by aircraft type. The user can then share those totals with this conversation. Use it when someone wants the CO₂ of their flying from their logbook.
No arguments.

}Lists the signed-in user’s TrimCarbon offset orders, newest first: date, source, kg of CO₂, status and the public certificate link once issued. Needs the user to connect their TrimCarbon account.

}Returns what TrimCarbon charges to offset an amount of CO₂: a one-time purchase in whole tonnes, and for yearly amounts the monthly and yearly plans. Each option has a link to continue on trimcarbon.com, where the user signs up and pays. This tool does not buy anything. It is for when the user asks what offsetting costs.
| Argument | Type | Description |
|---|---|---|
| kg* | integer | kg of CO₂ to offset, usually from an estimate tool |
| hours | number | Hours per year, to prefill sign-up |
| period | string | "year" for yearly CO₂ (plans apply), "total" for a one-off amount |
| aircraft | string | The main aircraft type, to prefill sign-up |

}Finds the aircraft types TrimCarbon has figures for, by name (e.g. "Cessna 172", "Skyhawk"), ICAO type designator (e.g. "C172", "PA28") or page slug. Returns each type with its kg of CO₂ per flight hour. The list covers about 60 general-aviation types, plus a few airliners (per passenger) and business jets.
