Climate Impact

Travel & Tourism (T&T) is responsible for carbon emissions – but you can take action.

“REP” your Planet!

This topic can feel complex. Let us help you make informed decisions.


  • Travel less frequently
  • Visit places closer to home
  • Stay in your destination for longer
  • Plan your route responsibly (trains, direct flights)


  • There are tons of calculators to choose from
  • Each tool will give you a different answer
  • Don’t worry about getting it perfect!
  • Any estimation is better than none

See our top picks for calculators


  • Understand your options (offsets, removals)
  • Do what you can afford
  • Factor this into your overall trip cost
  • Know where your money is going

Carbon Offsets vs. Carbon Removals

What’s the difference?

Comparing Offsets and Removals

Carbon offsets and removals are both good and necessary.

Offsets are cheaper, and the benefits will take longer to see.
Removals are more expensive, and the benefits will be effective immediately.

Using a combination of both will help protect the planet today and tomorrow.

Estimate your Carbon Impact

Our top picks for carbon calculators:

Choose between calculating distance or carbon dioxide emissions.


air miles calculator 

Air Miles Calculator

Calculate the miles, kilometers, and nautical miles between two or more airport codes. You can also search for flights by airline.

Calculate flight distance

International Civil Aviation Organization 

International Civil Aviation Organization (ICAO)

This calculator is specifically for the carbon dioxide emissions from flying, though it will also give you the mileage and kilometers.

Use the CO2 amount to pay for offsets based on an estimated carbon amount, rather than mileage.

Calculate your flight’s CO2

Purchase Carbon Offsets

Our top picks for carbon offsets:

After sifting through 20+ offsetting tools, here are our favorites for travelers.

Sustainable Travel International

Sustainable Travel International Logo

Enter in the number of people, flight distance in miles, and whether you flew economy or premium class. 

If you know the estimated amount of CO2 generated from your trip, you can also offset a specific amount of CO2.

You can also offset in bulk by entering in the number of short-haul, medium-haul, and long-haul flights you’ve taken.

Purchase offsets

Jet-Set Offset

Jet-Set Offset Logo

With Jet-Set Offset, you can donate one cent per mile to environmental non-profits fighting climate change (your donations are 100% tax-deductible in the US).

There are two ways to donate: add your flights manually, or forward flight confirmation emails to Jet-Set Offset.

Sign-up to offset

Cool Effect

Cool Effect

Don’t worry about calculating flight mileage and simply offset based on your flight duration: 0-6, 7-9, 10-12, or 13+ hours. You can also offset based on the CO2 amount if you know it.

What you pay to offset is 100% tax-deductible in the US, and more than 90% of your donation will go straight toward climate projects.

Offset by flight duration

Mini Case Study: What does it cost to offset a round-trip flight between Seattle and Paris?

One reason carbon offsetting can feel overwhelming for travelers is that there are a lot of options, and each option can give you really different results. Let’s consider a round-trip flight from Seattle (SEA) to Paris (CDG). 

  • Sustainable Travel International: Using Air Miles Calculator, we find the round trip mileage to be 10,032 miles. Assuming an economy-class flight, STI calculates a carbon footprint of 4,916 pounds of CO2. This will cost $27.87 to offset.
  • Jet-Set Offset: Flight mileage is automatically calculated after entering the airport codes, and matches the 10,032 miles found by Air Miles Calculator. Based on a donation of one cent per mile, offsetting the flight will cost $100.32.
  • Cool Effect: The flight duration between Paris and Seattle is about 10 hours. Cool Effect applies a long-haul estimate of 1.89 tonnes of CO2 per leg, so a round-trip flight would generate 3.78 tonnes, and cost $46.12 to offset.

Some of the reasons these numbers are so different are because the donation methodology, carbon offset projects, service fees, tax benefits, and other factors are varied. This is normal!

We encourage travelers to find a donation mechanism that is within their price range and supports projects they truly care about. Most important of all is to avoid “analysis paralysis” – take some action instead of none, and if you find a better way to offset in the future, you can always change how and where you give back to the climate.


Purchase Carbon Removals

Our top pick for carbon removals:

Carbon removal programs are less prevalent than carbon offsetting programs, and we especially love this removals company because they target mindful travelers.

Tomorrow’s Air

Designed specifically for travelers, Tomorrow’s Air uses innovative technology to remove carbon from the atmosphere and store it permanently underground.

Purchase carbon removals through monthly subscriptions for as little as $10/month.

Swipe to see how it works!


How It Works

Tomorrow’s Air uses climeworks technology to pull air into a carbon removal collector with a fan. Carbon dioxide is captured on the surface of a filter inside the collectors. Once the filter is full of carbon dioxide, the collector is closed. High concentration carbon dioxide is mixed with water and pumped deep underground. Through natural mineralization, the CO2 reacts with basalt rock and turns into rock.


Yugen Earthside is a Climeworks Pioneer

As a monthly subscriber of Tomorrow’s Air, we’re helping to remove 85 kg of CO2 per year from the atmosphere and permanently store it using climeworks’ technology.
