Porsche Cars North America has announced that its fleet vehicles will be carbon neutral thanks to its new carbon-offset program.

The automaker’s North American fleet, which consists of 425 vehicles including the cars at the Porsche Experience Centers in Atlanta and Los Angeles, will be enrolled in Porsche Impact, a program that allows Porsche owners to offset their carbon emissions. Porsches also used in the Porsche Passport subscription service and Porsche Drive short-term rental programs will also be included.

Individual owners of Porsche models will be able to use the Porsche Impact tool to estimate how much carbon dioxide their vehicles have produced. The application takes into account the mileage driven, the average miles per gallon, and the type of fuel used. Owners can then select between various projects that offset these emissions. For example, contributions can be made to biodiversity projects helping forests in the United States, hydropower in Vietnam, solar energy in Mexico, and species diversity in Zimbabwe.

Porsche says that driving a 2019 Cayenne S for 10,000 miles (16,000 km) a year would generate an offsetting contribution between $67 and $152 annually, depending on what program the owner decides to support.

While the Porsche Impact program is only currently available to vehicles in Porsche’s North American fleet, it will soon be rolled out to all of its U.S. customers.

“At Porsche, we are continually focused on innovative and sustainable business practices,” president and chief executive of Porsche Cars North America Klaus Zellmer said. “Porsche Impact is another way for us and our customers to help offset carbon emissions as part of our goal to become the most sustainable premium sports car manufacturer in the world.”
