I like knowing that my booking supports reforestation projects. It feels good to book on TripZero.Daphne Church | San Francisco, CA
Your TripZero reservation enables us to fund reforestation projects around the globe. As these forests grow, they absorb carbon dioxide—the main greenhouse gas driving climate change—eliminating the pollution created by your trip.
We Support: Patagonia Sur
Your trip helps to fund the largest native-species reforestation campaign in Chile’s history and the first to receive accreditation under the Verified Carbon Standard. The project plants native-species trees in a pattern that replicates the growth of a natural forest. During its lifetime, each tree will remove over 1,000 pounds of CO2 from the atmosphere.
Forest Protection Works
Your reservation helps fund forest protection programs, replacing slash and burn agriculture with forest cultivation. Employing local residents to plant a mix of trees, including fruit and nut bearing species, creates long-term jobs and food security. In turn, these protected forests absorb carbon dioxide and offset the impact of your trip.
We Support: Wildlife Works REDD+ Forest Protection in Kenya
Your trip helps fund the protection of 500,000 acres of highly threatened forest in Kenya and creates hundreds of jobs in the local community. Adhering to both the Verified Carbon Standard and the Climate Security and Biodiversity Standard, this project eliminates 1.2 million tonnes of CO2 emissions annually.
Renewable Energy Works
Your TripZero reservation supports the construction of renewable energy projects, like wind farms and solar power plants. These clean energy sources replace dirty ones, offsetting the pollution created by your trip.
We Support: The Indiana School Wind Project
Your trip helps fund the construction of wind turbines on school campuses in Northern Indiana. Validated to the Verified Carbon Standard, these turbines will offset 39,000 tons of greenhouse gas in their first ten years of operation. And they’ll also lower school energy costs, leaving more money for education.
Renewable Energy Builds Local Economies
Your TripZero reservation enables local landowners—often family farms—to produce new income while preserving their land. And the clean energy and revenue they produce literally powers the local economy.
We Support: Pátu Wind Farm
Your reservation helps fund the construction of a small wind farm in Wasco, Oregon on land that’s been family owned for 150 years. These turbines will eliminate 19,000 tons of greenhouse gas each year. And they’ll produce enough energy to power 2,200 homes.
Methane Capture Works
Your TripZero reservation supports projects that eliminate methane, a greenhouse gas that’s 21 times more harmful than carbon dioxide. Preventing methane release offsets the carbon footprint created by your trip.
We Support: Northeast Farm Separation Project
Your reservation helps fund the installation of manure processing equipment on the Mercer Vu farm in Mercersburg, Pennsylvania. Validated to the Verified Carbon Standard, this equipment will eliminate 72,000 tons of greenhouse gas.

Interested in knowing more about carbon offsets?
Here you'll find the answers to some of the most common questions we're asked.
So what is a carbon offset anyway?
In the simplest terms, a carbon offset is a certificate (like a stock certificate) that represents the reduction of one ton of carbon dioxide. Qualified projects that reduce CO2 emissions (like reforestation and renewable energy initiatives) can issue one carbon offset certificate for every ton of CO2 they eliminate.
Individuals and organizations purchase these certificates to offset carbon emissions created by their actions. In turn, they provide financial support that enables the project to operate.
How do you know that the carbon offsets are really happening?
The carbon projects we support have undergone a rigorous third-party certification process. Which means that the carbon offsets they produce are real and verifiable.
The organizations that certify carbon projects rely on collaboration among scientists, environmental organizations and governments to create standards that certified carbon projects must meet.
The projects we support adhere to internationally recognized standards like:
Although the standards differ, they share common requirements. In order to meet certification standards:
- Projects must demonstrate additionally. In other words, the project must generate greenhouse gas reductions beyond those required by law or by "business as usual." Further, projects must demonstrate that these reductions would not occur without the financial support provided by the sale of carbon offsets.
- Projects must generate greenhouse gas reductions that are permanent, quantifiable and validated by an accredited third party.
- Projects must list carbon offsets with independent registries to ensure that each certificate is unique and has only been sold once.
By supporting projects validated to these standards, we're confident that we offset the carbon emissions created by our customers' travel. If you have ideas about how we might do an even better job, please contact us.
How do we calculate your trip’s carbon footprint?
Transportation + Hotel Stay = Travel Footprint
When we calculate the carbon footprint for your trip, we include both the impact of your transportation (flight, train, car or bus) and your hotel stay. TripZero is powered by the award-winning Brighter Planet CM1 computational sustainability platform. We believe it’s the most sophisticated and accurate carbon calculation tool in the world.
The CM1 platform relies on internationally recognized open-source data and transparent calculation methodologies that anyone may review online. The results that the system produces support compliance with rigorous international standards including the Greenhouse Gas Protocol, ISO 14064-1, and The Climate Registry. As a result, Brighter Planet has received awards from the Financial Times and the U.S. Environmental Protection Agency.
If you’re sustainability professional, scientist or energy enthusiast we urge you to review the various Impact Models that make up the CM1 platform and review the Narrative Methodology Statement for each model. You’ll find step-by-step descriptions of each calculation and direct links to the underlying data sources.
If you’re an everyday traveler (like most of us) you might find the process fascinating, although you’ll need a little time to develop a deep understanding.
The basics of calculating your travel footprint.
Your trip’s carbon footprint has two parts: transportation and hotel. We calculate these items separately and then combine them to express your total footprint.
Part 1: Transportation footprint.
The formula for calculating your transportation footprint combines the effect of:
- Your mode of transportation.
- Are you flying, driving, taking the train or riding a bus? The fuel efficiency of these activities varies widely, especially once we factor in the distance you’ll travel and the number of travelers in your party.
- Your trip’s origin and destination.
- Where does your trip begin and end? This information enables us to calculate the total miles you’ll travel. It also enables us to take secondary factors into consideration. For example, if you’re flying we’re able to use airport information to factor in the carbon effect of delays.
- The number and type of passengers traveling.
- How many people in your party? Any children? As a general rule, more travelers mean more carbon footprint. However, there are some notable exceptions. For example, on flights, we assume that children under two don’t occupy their own seats or contribute to your carbon footprint in a meaningful way.
Part 2: Hotel footprint.
The formula for calculating your hotel footprint combines the effect of:
- Your hotel’s location.
- Our calculation incorporates the impact of the local climate and the energy required to heat or cool your hotel. We also use location to determine the fuel used to create and supply electricity to your hotel.
- Your rooms and length of stay.
- We multiply the footprint of a single room day by the number of rooms your party will occupy and then again by the number of days you’ll stay.
Want more? Some advanced details on flight calculations.
One can apply a remarkable number of variables in an effort to come up with a "perfect" carbon footprint calculation. For example, take flights. Here are just some of the variables deployed in the TripZero flight footprint calculation and a brief explanation of why they matter:
Trips. We assume round-trip travel for every trip. For some travelers, this means we’re calculating (and offsetting) more carbon footprint than necessary.
Distance. Our calculation uses the nautical miles between destinations and adds in an appropriate factor to account for route inefficiencies. We do this because planes don’t typically fly directly between point A and point B; they need to spread out to avoid other flights and avoid restricted airspace (like military installations).
Segments. Planes use a lot of fuel during taxi, takeoff, climbing and landing. Even one stopover dramatically increases your carbon footprint. For short and medium flights, we assume direct travel. For long and international flights our calculation adds an appropriate factor (based on industry averages) to account for connecting flights.
Radiative Forcing. With advance apology to our friends at MIT, we’ll oversimplify this important factor. Scientists agree that when you "deliver" pollution to higher altitudes (as airplanes do) you magnify its impact on climate change. Relying on a study from the Stockholm Institute of this topic, our calculation applies a factor of 2.0—effectively doubling the standard carbon footprint calculation for a flight.
Seating Density. Full flights, on the same plane and route, have a lower footprint per passenger than flights that are only half full. Our calculation uses industry averages to compute the effect of load factor on your flight. Relying on averages means that may understate the impact of one trip and and overstate the impact of another. However across all of our customers, we’re confident that TripZero offsets the right amount of carbon footprint.
These are just a few of the variables we use to compute the carbon footprint for flights. As you might expect, we uses similarly complex models to calculate the footprint for each form of transportation and hotels.
How does our calculation compare to others?
We’ve compared the results of TripZero’s travel footprint calculations to those produced by a variety of well-regarded carbon calculators or published methodologies including:
- The US Environmental Protection Agency’s guidelines
- The TerraPass travel carbon calculator
- The Carbon Neutral Company flight calculator
- The British Petroleum carbon neutral calculator
When we conduct comparisons across bundles of trips (short medium and long), our calculation methodology typically yields total results that are somewhat higher than these models. On average, this results in our offsetting slightly more carbon footprint than customers’ trips might require.
