Porsche’s new factory building the upcoming Taycan electric vehicle will not only produce a green car, but it’ll also clean the atmosphere around it while they’re at it.

Ever since Dieselgate, Volkswagen has been fighting an uphill battle to be seen as a “green” car company. Something about cheating on emissions testing just makes it hard to seem like you’re really doing all that you can do to help the planet.

That might be why Porsche, one of the many luxury brands under Volkswagen Automotive Group, is so concerned with ensuring that the Taycan EV be as neon green as possible.

To that end, Porsche is not only making a car with zero emissions, they’re also making it so the factory where the Taycan is built actively sucks pollutants out of the air, making the production of the Taycan completely carbon-neutral.

At the new factory built to produce the Taycan at Porsche headquarters in Stuttgart-Zuffenhausen, the exterior of the factory will be coated in an advanced nitrogen dioxide-absorbing surface technology. Made out of aluminum coated with titanium dioxide, the factory facade breaks down nitrogen dioxide into harmless water and nitrates when exposed to sunlight and in low humidity conditions.

Nitrogen dioxide, or NO2, is a major chemical component of urban smog. It’s also something that comes spewing out the back of all those diesel-engined cars that cheated on their emissions tests a few years back.

Shortcomings of the technology are that it requires sunlight and low humidity, so it doesn’t work if it’s raining. But the benefits are that it’s completely passive technology that requires no energy or moving parts.

Porsche’s pilot project coats 1,356 square feet in the NO2-absorbing material, which performs the work of 10 trees on the area the size of 10 parking spaces.

“Sustainability is a big picture that is made up of many individual elements,” explains Albrecht Reimold, member of the Executive Board responsible for Production and Logistics at Porsche. “We are therefore continuously thinking about the measures that we can implement to ensure greater sustainability in our actions – throughout the entire value chain.”

So, now when someone comes up to you and says that your $90,000 Porsche isn’t really zero-emissions because that fails to consider the emissions made at the factory, you can both tell them they’re wrong and still feel smugly superior while you do it.
