1Carbon dioxide emissions for flight activity are estimated using several factors such as: aircraft type, fuel consumption, and load factor. Emission estimates are based on the fleet wide distance-weighted average performance of Southwest’s flights from the Second Quarter of 2021. Southwest’s emissions estimates do not quantify the potential climate change impact of non-CO2 emissions resulting from a flight.

2Taxes and fees will not be matched by Southwest or earn points. Rapid Rewards® Members can earn 10 Rapid Rewards bonus points per dollar contributed towards the purchase of offsets for Southwest 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. All offsets will be retired in the name of Southwest Airlines Co. Terms and conditions apply.

Your contribution makes a difference.

Every time you show our planet love by contributing, you’ll be supporting global projects like the ones below.4 The three groups we’re currently partnering with are The Guatemalan Conservation Coast, the Los Santos Wind Power in Costa Rica, and the Kootznoowoo Improved Forest Management Project in Alaska.

Kootznoowoo Improved Forest Management Project in Alaska

Alaskan forest

This project offers a sustainable economic engine for the Kootznoowoo Alaska Native Village Corporation to continue safeguarding their land and preserving their cultural heritage for the long term. The carbon revenue allows the Tlingit people to protect more than 20,000 acres of forest, including 8,000 acres of old growth land that could otherwise undergo significant commercial timber harvesting. Maintaining the existing forest avoids CO2 emissions that would result from aggressive timber extraction and loss of carbon stock.


The Guatemalan Conservation Coast

Tree frog

Located in Izabal, on the Caribbean Coast of Guatemala, the project finances the establishment of new nature reserves and supports existing natural forests, avoiding CO2 emissions that would result from unplanned deforestation and degradation.

Los Santos Wind Power Project

Wind turbines

The national electrical grid in Costa Rica has greatly expanded in recent years; there's a plan in place to invest further in diesel generation facilities in the future. This project generates clean electricity and avoids around 15,000 tons of CO2 emissions annually, which would have been generated by other power plants connected to the national electrical grid. It is also the first wind power project to be developed in Costa Rica by a rural electrification cooperative.

Southwest makes no independent representations or guarantees with respect to the offset ultimately purchased or sourced by CHOOOSE™ using contributions made through http://southwestCO2.com or with funds contributed by Southwest.

Frequently Asked Questions

Carbon offsetting is a climate action that enables individuals and organizations to offset the CO2 emissions associated with certain activities by supporting projects that reduce, capture, or avoid a proportional amount of CO2 emissions.

When Customers contribute funds for the purchase of offsets through southwestCO2.com to offset Southwest’s carbon emissions, those funds are used to purchase carbon offsets sourced from projects that reduce, capture, or avoid carbon emissions. The carbon offsets are retired in Southwest’s name and used to offset Southwest’s 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, a fee is charged for credit card processing and for standard administration and support services from Southwest’s climate partner CHOOOSE™. The administration and support services fee is just $0.40 per Passenger per transaction, and this helps to cover CHOOOSE™’s running costs.

The carbon offsets are sourced from an approved portfolio of projects across the globe that avoid carbon emissions. Our current portfolio includes the following projects that avoid carbon emissions:

  • The Guatemalan Conservation Coast — Located in Izabal, on the Caribbean Coast of Guatemala, the project finances the establishment of new nature reserves and supports existing natural forest, avoiding CO2 emissions that would result from unplanned deforestation and degradation, such as ‘slash and burn’ agriculture. The project area is highly important for biodiversity conservation because it serves as a wintering and stopover site for over 120 species of migratory birds. The project is critical to the local water supply, building up natural coastal defenses and supporting local agriculture.
  • Los Santos Wind Power in Costa Rica — The national electrical grid in Costa Rica has greatly expanded in recent years, with further investment in diesel generation facilities planned. This project in the Los Santos region generates clean electricity and avoids around 15,000 tons of CO2 emissions annually, which would have been generated by other power plants connected to the national electrical grid. It is also the first wind power project to be developed in Costa Rica by a rural electrification cooperative. As one of the country's windiest regions, Los Santos is located south of the capital of San José in the rugged mountain ranges of Costa Rica where most people work in agriculture and cattle raising. While generating clean electricity, the project aims to achieve sustainable and economic development by supporting the local communities in improving infrastructure as well as to educate the population on sustainable energy consumption, climate change, and biodiversity.

  • Kootznoowoo Improved Forest Management Project in Alaska — This project offers a sustainable economic engine for the Kootznoowoo Alaska Native Village Corporation to continue safeguarding their land and preserving their cultural heritage for the long term. The carbon revenue allows the Tlingit people to avoid CO2 emissions that would result from aggressive timber extraction and loss of carbon stock. The project protects 20,159 acres of forest, including 8,000 acres of old growth, in the Dolomi and Dora Bay tracts of Prince of Wales Island. Until now, this area was a significant timber source for the Japanese market. The project location includes several different ecosystems, from beach to high elevation. The diverse land hosts many different types of berries and animal habitats such as Sitka black-tailed deer, black bear, mountain goat, moose, beaver, weasel, land otter, and red fox.

This portfolio is subject to change at any time, and either CHOOOSE™ or Southwest may utilize contributions to purchase carbon offsets from other projects in their sole discretion. Southwest relies solely on CHOOOSE™ AS to verify the integrity, quality, and permanence of all offsets purchased with contributions made through southwestCO2.com or with funds contributed by Southwest. Southwest makes no independent representations or guarantees with respect to the offset ultimately purchased or sourced by CHOOOSE™ using contributions made through southwestCO2.com or with funds contributed by Southwest.

Because we offer Customers the opportunity to make offset contributions at a fixed price prior to the time when the offsets are actually purchased on Southwest’s behalf, our program retains the ability for us to allocate contributed dollars for the purchase of offsets across our selected portfolio of projects to deliver the carbon benefits to which customers have contributed at the fixed prices offered through southwestCO2.com.

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.

Carbon dioxide emissions for flight activity are estimated using several factors such as: aircraft type, fuel consumption, and load factor. Emission estimates are based on the fleet wide distance-weighted average performance of Southwest’s flights from the Second Quarter of 2021. Southwest’s emissions estimates do not quantify the potential climate change impact of non-CO2 emissions resulting from a flight.
