Environmental burden of cars is far from being given only to their operation, but especially also the production. "Production of a Toyota Prius causes much greater damage to the environment than the Hummer, which last operated three times more than Prius," wrote the article "The hybrid organic?" magazine Donkey. And, for example, according to reports on Sustainable Development 2007/2008 (PDF) of Skoda Auto, the total emissions per car produced 5.57 kg.

"These are all emissions from the operation of the factory. It is therefore only CO2. It is the emissions from heating, svaroven, SkoEnergo and the like. More precisely, for all emissions reported in accordance with the obligations of the law on air protection, "says David Sikula of Skoda Auto in the article on the web EnwiWeb. In doing so, moreover, consumes about 1.81 MWh of energy to the production of one car. This gives automobile reason to modernize their operations. Some of the factory installed on your solar panels, such as Ferrari or General Motors. Toyota to respect the domestic Japan from the forest, the factory in Tsutsumi is one of five factories known as "Eco-Factories", which are to minimize the impact on the environment and napomoct develop the best practices of organic production, which could then be applied further.

The factory produced models of the Toyota Prius the third generation. Roof of the factory covers 50 000 m2 of solar panels, Solar power plant can produce 2000 kW of energy per hour. The rest of the energy efficient supply cogeneration system, throughout the service is installed efficient lighting, energy saving at the time the plant out of service, using the natural lighting and sunlight. Total 22 000 m2 factory is covered fotokatalytickym coating, which reacts with sunlight and air to release active oxygen depriving surrounding hazardous pollutants. In order to match the production of carbon dioxide, factory workers, together with the local people planted a total of 50 000 trees around the whole factory - only in 2008. According to press reports car with CO2 emissions from factories declined during the years 2003 to 2007 by 36%. Organic plant life to be 100 years old!
