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?

The infographics below give a good overview, but check out our detailed blog post, Carbon Offsets & Carbon Removals Explained, for more information.

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.

Read our blog post for a much more detailed look into carbon offsets and carbon removals.

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

Or, swipe to see how to calculate CO2.

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:

We’ve compared 20+ carbon offsetting tools. Here are our favorites for travelers.

Sustainable Travel International

Sustainable Travel International Logo

Select whether your trip is a round trip, one-way, or multi-city flight, the number of people flying, and economy or premium class. 

Then, enter the airport codes between your destinations and click “Calculate”.

The results will show the estimated metric tonnes of CO2 emitted and the cost to offset. 

Purchase offsets

If you want to offset a specific amount of metric tonnes, or offset a particular dollar amount, you can do that, too.

Jet-Set Offset

Jet-Set Offset Logo

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

After you sign up and create your account, you get to choose amongst their environmental organization partners which one you donate to. 

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. Toggle the “# of Trips” to 2 for a round trip.

The results will show the estimated metric tonnes of CO2 emitted and the cost to offset. 

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

You can also compensate based on the tonnes of CO2 if you know your trip’s estimated output.

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: STI calculates the carbon footprint of an economy flight based on the mileage between SEA and CDG. Their results show 2.24 metric tonnes of CO2 which will cost $35.84 to offset ($16.00/metric tonne).
  • Cool Effect: Cool Effect does not base its calculation on airport codes, but rather on ranges of flight times. The flight duration between Paris and Seattle is about 10 hours. Using the ’10-12 hours’ duration bucket, 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 $55.26 to offset ($14.62/metric tonne).

The cost to offset similar amounts of carbon can vary due to things like the project type, project location, implementation tactics, research and science behind the project, whether the project is run by a for-profit or not-for-profit company, and the percentage of the cost going to the carbon initiative. Read more about these variables in our blog post.

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 Logo 

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.

Yugen Earthside is Proudly Net-Zero

We earned our third-party certification through Ecolytics

Yugen Earthside uses a combination of carbon removals through Tomorrow’s Air and carbon offsets through Pachama to achieve our net-zero status. Ecolytics uses software to help companies evaluate the emissions caused by normal business operations. Ecolytics takes into account climate actions companies are already taking and provides impact reports and recommendations for what else companies can do to lessen their environmental impact.
