CO2 Emissions from New Vehicles (Global)*

In fiscal 2018, CO2 emissions in Nissan’s main markets of Japan, the U.S., Europe and China were 33.0% lower than fiscal 2000 levels, as measured by Corporate Average Fuel Economy (CAFE). This was a slight regression from fiscal 2017 due to changes in the powertrain sales mix in the EU.

  • Reduction in CO2 emissions calculated by Nissan.

Corporate Average Fuel Economy (CAFE, JC08 Mode) in Japan

In fiscal 2018, mainly due to strong sales of the Serena e-POWER, average fuel economy improved to 21.2 km/L in JC08 mode. This represents an improvement of 3% compared to fiscal 2017. Provisional values determined by Nissan are used.

Corporate Average Fuel Economy (CAFE) in the United States

In fiscal 2018, sales resulted in a CAFE of 39.8 mpg for passenger cars, the same performance observed for fiscal 2017. In the light-duty truck segment, comparatively heavier models sold well, worsening the CAFE from 29.1 mpg to 28.5 mpg.

CO2 Emission Index from Nissan Vehicles in Europe

In 2018, there has been a substantial decrease in sales of diesel fuel vehicles, which resulted in average CO2 emissions at the same level as 2017.

Corporate Average Fuel Economy in China

In 2018, fuel economy for domestically produced and imported vehicles improved approximately 5% and 2%, respectively. The incremental introduction of EVs is the main factor for domestic production improvements, whereas a profile of lighter models contributed to the imported vehicles results.

Global Energy Consumption

The total energy consumption of our global corporate activities during fiscal 2018 was about 9.253 million MWh, a 3% decrease from fiscal 2017. This reduction was primarily due to the promotion of energy-saving activities at facilities and a decline in total production volume. Production sites globally accounted for 8.161 million MWh* of total energy consumption.

Resource Dependency: Achievements in Reuse

Proper Use of Regulated Chemical Substances

Nissan revised its standard for the assessment of hazards and risks in the Renault-Nissan Alliance, actively applying restrictions to substances not yet covered by regulations but increasingly subject to consideration around the world. As a result, the number of substances covered by the Nissan Engineering Standard in fiscal 2018 rose to 4,043. These steps are thought to be necessary for future efforts in the repair, reuse, remanufacture and recycle loop for resources.

Recycled Plastic Usage in Vehicle

We are making efforts to expand the use of recycled plastic in our vehicles, as well as developing technologies for this. Recycled plastic use in fiscal 2018 was 11%, based on the rate achieved by our best-selling model in Europe.

Automotive Shredder Residue to Landfill Ratio

After removing ferrous and nonferrous metals from ELVs, in accordance with the End-of-Life Vehicle Recycling Law in Japan, the ratio of ASR taken to landfills for final disposal was zero in fiscal 2018. This was achieved by enhancing recycling capability through the acquisition of additional facilities that comply with the law.

Material Ratio

In 2018, ferrous metals accounted for 61% of the materials used in our automobiles by weight. Nonferrous metals made up another 15% and resins 14%, with miscellaneous materials making up the final 10%. To further reduce our use of natural resources, we are advancing initiatives to expand the use of recycled materials in each of these categories.

Strengthening Our Business Foundations to Address Environmental Issues

Global Top Selling Model’s Lifecycle Improvements

We have been expanding the application of the LCA method and enhancing the understanding of the environmental impact of our products in quantitative terms, especially our best-selling models worldwide. LCAs have been conducted for over 90% of these models.

LCA Conducted Product Ratio in Sales Volume (EU Market)

With the Altima and Rogue, for example, improvements in internal combustion engine efficiency and vehicle weight reduction have led to both enhanced safety features and lower CO2 emissions.

LCA Comparison for e-POWER Models

Nissan introduced its new e-POWER powertrain in 2016, marking another significant milestone in the electrification strategy with lifecycle emission improvements.
Compared to their gasoline-powered counterpart models, the Note e-POWER and Serena e-POWER have achieved 18%—27% reductions in CO2 emissions.

LCA Comparison for the New Nissan LEAF

Compared to conventional vehicles of the same class in Japan, the Nissan LEAF results in approximately 32% lower CO2 emissions during its lifecycle. We are making efforts to reduce CO2 emissions during EV production by improving the yield ratio of materials, using more efficient manufacturing processes and increasing the use of recycled materials.

Lifecycle CO2 Equivalent Emissions (CO2, CH4, N20, etc.)

Lifecycle Improvements Beyond Climate Change

Nissan is expanding the scope of LCAs to include not just greenhouse gases but also a variety of chemicals amid growing societal concerns over air quality and ocean acidification and eutrophication. Our calculations show that, compared to conventional gasoline engines, the Serena e-POWER is significantly more environmentally friendly, achieving 11%—27% emission reductions for all targeted chemical substances and achieving environmental benefits throughout its lifecycle.
