How to fill in the calculator

For whoever on your team is filling this in. No climate background needed.

What you are doing

You're estimating how much carbon dioxide your organization puts into the air in a year, so you can fund the same amount of removal. The answer is a number of tons. For scale, a round trip between New York and London in economy comes out to about 2 tons here.

It doesn't have to be exact. A reasonable estimate is okay. The calculator rounds your total up and shows a likely range. Landing at 90 or 95 tons won't change what you do, so don't spend hours chasing exact figures.

Before you start, gather

  • Your flights for the year (the big one). See page 2.
  • Hotel nights, if you can add them up quickly.
  • Optional: staff count, office details, and a rough yearly operating budget.

What you can skip

Any field. Everything below the flight and travel sections is optional, and you can come back to it later. Investments are shown on their own and aren't added to your total.

Steps

  1. Paste your flights into Staff & Board Flights, one trip per line.
  2. Add flights for grantees or partners you pay for, if any.
  3. Add hotel nights and any rental car, train, or private aircraft use.
  4. Open the optional sections you have time for.

Reading your result

You seeWhat it means
Annual footprintYour estimate in tons per year, rounded up. Plan around this number.
Likely rangeA rough low and high. Rounding up covers most of the gap.
What removal could costYour tons at each of Terraset's four price points per ton, from fastest impact to most permanent. We recommend Balanced. Confirm current pricing with Terraset.
Where it comes fromThe split by category. For a lot of organizations, flights lead.
Your investmentsFor context only. The share of emissions tied to what your endowment owns and where your cash sits. It isn't part of the number above.

How to pull your flight list

Flights are the biggest piece for almost every organization, and the hardest to gather. Use whichever route is easiest for your team.

What you need for each flight

The airport you left from and the airport you landed at. That's it. You don't need dates or prices, just the three-letter codes (BOS, LHR, SFO). If someone flew business or first class, note it.

Four ways to get the list

RouteHow
Your expense or card systemFilter to airfare for the calendar year and export. Many exports show the airline and amount but not the route. If yours has an itinerary or trip field, use it. If not, move to another route for the missing airports.
Your travel booker or agencyAsk for an annual air itinerary report. It usually lists every segment.
Your staff and boardShare a simple sheet and ask each person to add their trips in the format below. Ten minutes each should do it.
Email confirmationsSearch a mailbox for "itinerary," "e-ticket," or "confirmation" for the year. Each person can do their own and send back just the airport codes.

How to write them

Write it like thisWhat it means
BOS-LHR-BOSA round trip, which is two flights
SFO-JFKA one-way flight
DEN-SEA-DEN biz x3Business class, three times
BOS-ORD-SFOA connection, which is two flights

If you can't get routes

Use Or add flights by count under the paste box. Count one-way flights, so a round trip is two, and pick short, medium or long. Being off by a few trips is fine.

If an airport isn't recognized

The calculator knows more than 7,000 airports. If a code isn't recognized, check for typos, or add that flight by count. City codes like NYC and LON also work.

Other travel

Hotel nights, rental cars, ride-share, and train miles go in Hotels, Ground Travel & Private Jets. Estimates are fine. For private or chartered aircraft, enter hours flown and aircraft type instead of airports.

Tip. If you only do one thing, do flights. Everything else is optional and can wait.
