For Nissan, the reduction of CO2 from vehicles in use is a serious issue. We are actively involved in the development of new technology to enhance fuel economy, and technical innovations such as the development of fuel cell vehicles.

Nissan pursues technology development, mindful of the potential effects emissions can have on society. In addition to official test modes in Japan such as the 10-15 mode, Nissan established its own in-house standard for a benchmark to measure what we call "real world fuel economy," which is based on evaluations of a broad range of 'real world' driving situations and which is used to develop effective technologies for improved fuel economy.

Nissan has taken a comprehensive approach to CO2 reduction, developing fuel-efficient engines, highly efficient transmission systems, lightweight vehicle bodies as well as more aerodynamic vehicles with low air resistance.

At Nissan, we assess the fuel economy of all vehicles sold and their impact on the environment by monitoring the average corporate fuel economy trends.
In Japan and the US, the figure used is fuel economy, whereas in Europe the figure used as the most relevant measure is that of CO2 emissions. These figures are reflected by fuel economy and annual unit sales. Nissan promotes the reduction of CO2 emissions by setting mid to long term targets to achieve the regulation standards in a given region.
