1Carbon emissions for flight activity are estimated using several factors such as: aircraft type, conventional jet fuel consumption, flight distance, and assumed load factor. Emission estimates are based on the fleet wide distance-weighted average performance of Southwest's flights from the Second Quarter of 2023. Southwest's emissions estimates do not quantify the potential climate change impact of non-carbon emissions resulting from a flight or non-flight factors, such as the production or transportation of conventional jet fuel to the aircraft prior to takeoff. Actual carbon emissions may vary from estimates.

2Taxes and fees (except for the processing fee) will not be matched by Southwest or earn points. Rapid Rewards® Members can earn 10 Rapid Rewards bonus points per dollar spent on offsets up to a maximum of 500 Rapid Rewards bonus points per month. Points will only be awarded to the Member's Rapid Rewards account number entered at the time of the carbon offset transaction. Southwest's matching contribution will be used to purchase additional offsets to support global projects, and such additional offsets will be retired for Southwest. Terms and conditions apply.

So, what's all this about
offsetting carbon?

We have set a goal to be net zero by 2050.

We have also set a series of nearer term targets including:

  • Reduce our carbon emissions per revenue ton kilometer by 25% by 2030 and 50% by 2035*
  • Replace 10% of our total jet fuel consumption with sustainable aviation fuel by 2030.
  • Partner with organizations whose work supports our goals.

    And, of course, carbon offsetting.

*As compared against a 2019 baseline on a revenue ton kilometer (RTK) basis (including Scope 1, Scope 2, and Scope 3 Category 3 emissions (upstream emissions of jet fuel)). Includes the use of SAF and excludes the use of carbon offsets.

Estimate your carbon.

Add your flight details to our calculator to estimate how much carbon is emitted from the flight of your choosing, then you can purchase offsets to help address your emissions. While the entire carbon and other environmental impacts from your trip may not be eliminated by your purchase, your purchase shows your love for the Planet by offsetting some of your carbon emissions.1 (i).

This calculator and purchase widget is a CHOOOSE website, and CHOOOSE's terms and policies, including the Data Protection Policy will apply.

Your purchase makes a difference.

Every time you show our planet love by purchasing offsets, you'll be supporting global projects like the ones below.3

Kootznoowoo Improved Forest Management Project in Alaska

Alaskan forest

The carbon revenue generated from this project enables the Haida and Tlingit people to protect acres of forest land that could otherwise undergo aggressive commercial timber harvesting.


The Guatemalan Conservation Coast

Tree frog

The project finances the establishment of new nature reserves and supports existing natural forest, avoiding carbon emissions that would result from unplanned deforestation and degradation. The project is critical to the local water supply, building up natural coastal defenses and supporting local agriculture.

Delta Blue Carbon

Tidal wetlands

The Delta Blue Carbon Project is a mangrove restoration project on the southeast coast of Sindh Province in Pakistan. This project supports reforestation and revegetation of degraded tidal wetlands with indigenous mangrove trees and other species. The project works to stabilize and protect the coastal area, preserve the region's biodiversity, and support the communities that depend on these wetlands.

Frequently Asked Questions

Carbon offsetting helps organizations offset carbon emissions associated with certain activities, like flying, by supporting projects that avoid carbon emissions.

When Customers purchase offsets through southwest.com/wannaoffsetcarbon, those funds are used to purchase carbon offsets sourced from projects that avoid carbon emissions.

All of the funds are applied directly to carbon offsets sourced from projects, excluding taxes and fees on each transaction. For each transaction, fees are charged for processing and for standard administration and support services from Southwest's climate partner CHOOOSE™. The processing fee is 2.9% of the offset contribution + $0.30. The administration and support services fee is just $0.40 per Passenger per one-way transaction, and this helps to cover CHOOOSE™'s running costs. A "foreign transaction fee" may also apply to your transaction. This fee may be charged by the bank that issued your credit card that you used for your transaction, and the fee may appear on your statement as a "foreign transaction fee" or other similar description.

The below example explains how your contribution is allocated, using a price of $10.00 for your transaction.

    Example: Customer pays $10
  • - $0.5618 (Processing fee)
  • - $0.40 (Technology and Administration fee to CHOOOSE)

Carbon Offset Contribution: $9.02663
Fees: $0.97337

The example above does not include any foreign transaction fee that you may incur.

The carbon offsets are sourced from an approved portfolio of projects across the globe that avoid carbon emissions. Carbon offset contributions will be used to purchase offsets from projects like:

  • The Guatemalan Conservation Coast — The project finances the establishment of new nature reserves and supports existing natural forest, avoiding carbon emissions that would result from unplanned deforestation and degradation. The project is critical to the local water supply, building up natural coastal defenses and supporting local agriculture.
  • Delta Blue Carbon — This project supports reforestation and revegetation of degraded tidal wetlands with indigenous mangrove trees and other species.

This portfolio of projects is subject to change at any time without notice, and contributions may be used to purchase offsets for Southwest from carbon offset projects that are not presented on this website. Southwest relies solely on CHOOOSE™ AS to verify the integrity, quality, and permanence of all offsets purchased with contributions made through https://southwest.com/wannaoffsetcarbon or with funds contributed by Southwest.

Because we offer Customers the opportunity to purchase offsets at a fixed price prior to the time when the offsets are actually purchased, our program retains the ability for us to allocate Customer funds for the purchase of offsets across our selected portfolio of projects to deliver the carbon benefits which Customers have purchased at the fixed prices offered through southwest.com/wannaoffsetcarbon.

Carbon offsetting is performed through the purchase and retirement of third-party verified carbon offsets, which are units of emission equivalents used in voluntary offsetting programs. The carbon offsets made available to Southwest are called Verified Emission Reduction (VER) units, certified to an industry standard protocol.
