Environmental Initiatives

[Environmental policy] (established in July 2007)

NEXCO EAST positions environmental efforts as an important management issue, and contributes to the preservation of the global environment and the formation of a recycling-oriented society as a responsible member of society, as well as efforts to preserve the living environment and natural environment along the road. By advancing, we aim to be a company trusted by society.

[Environmental Action Guidelines] (Revised in January 2021)

NEXCO EAST will take the following actions based on its environmental policy.

I. Environmental conservation efforts

1. Contribution to the prevention of global warming
   • Expressway will contribute to the reduction of carbon dioxide by improving and strengthening the network of expressways, facilitating traffic by taking measures against traffic congestion, and improving the soundness of forests on slopes.
   • We aim for zero carbon dioxide emissions in 2050.
2. Contribution to the formation of a recycling-based society
   • By promoting 3R (Reduce, Reuse, Recycle) and green procurement, we will contribute to the formation of a recycling-based society.
3. Reduction of environmental load
   • We will comply with laws and regulations at all stages of our business activities and strive to reduce the environmental burden.
   • We will strive to build green infrastructure for the realization of a sustainable society.
   • We will endeavor to reduce the impact on the natural environment in order to contribute to the conservation of the biodiversity environment.
   • We will endeavor to reduce the impact on the roadside living environment.

Ⅱ. Technology development

• In order to contribute to the sustainable and effective prevention of global warming, the formation of a recycling-based society, and the reduction of environmental impact, we will work to utilize existing technologies and develop new technologies.

III. Environmental management initiatives

1. Environmental management
   • By analyzing and assessing the status of environmental conservation every year, we will carry out our efforts sustainably and effectively.
   • We carry out environmental management management according to ISO14001.
2. Communication
   • We will publish the results of environmental management in the "NEXCO EAST Report" to communicate with society.
   • We will engage in social and environmental activities in collaboration with local people, local governments, and countries.
3. Employee training
   • Through employee education, we will further raise employee awareness of the environment and foster a corporate culture.

【NEXCO東日本グループ　カーボンニュートラル推進戦略】

　NEXCO東日本グループでは、サステナビリティ経営を推進し、高速道路を通じて社会を支える使命を持続的に果たすため、サプライチェーンを対象に温室効果ガスの実質排出量の削減を推進する「NEXCO東日本グループ　カーボンニュートラル推進戦略」（以下、「本戦略」）を策定しました。
　NEXCO東日本グループは一丸となって、高速道路事業を通じた道路交通の円滑化などによる温室効果ガス排出量の削減に取り組むとともに、エネルギー消費の最小化や再生可能エネルギーの創造・活用を推進し、さらには産業界等とも連携した新たな技術の開発にも挑戦して、2050年カーボンニュートラルの実現に貢献してまいります。

　本戦略では、NEXCO東日本グループ（自社）の事業活動による排出（Scope1・Scope2）に加え、自社の事業活動に伴う間接的な排出（Scope3）を含む「サプライチェーン排出量」を対象とし、Scope1・Scope2のCO2排出量について削減策を計画・推進し、2050年度のCO2実質排出量ゼロの達成を目指します。また、中間的目標として2030年度におけるCO2排出量について2013年度比50％以上の削減を目指します。

　さらに、Scope3について政府が掲げる2050年カーボンニュートラルの実現と2030年度における目標の達成を目指し、CO2排出量削減に寄与する施策を推進します。

[ISO14001]

NEXCO EAST has acquired ISO14001 to implement sound and effective environmental management management. By running the PDCA cycle related to environmental activities, we manage environmental activities company-wide.

• ISO14001
  ISO14001 (Environment) is an international Standard for the environment issued by ISO (International Organization for Standardization) in 1996, and provides guidelines for introducing an environmental management system. This standard requires the construction and operation of an environmental response framework (management system) based on PDCA for the purpose of continuously improving the environmental response process in order to improve the environmental impact.

[Examples of environmental initiatives]

Use of energy-saving and highly visible lighting

By changing the lighting inside the tunnel from the conventional "high pressure sodium lamp" to "LED lamp", we are improving visibility and contributing to energy saving. So far, it has been installed in 301 tunnels, and in fiscal 2019, LED lamps will be installed in 28 new tunnels. It is estimated that the reduction in power consumption due to the change to LED lamps implemented so far is about 37 million kwh per year (about 20,000 tons per year for CO2 reduction).
We are also working to further reduce power consumption, such as by introducing LEDs not only for tunnel lighting but also for road lighting.

Reduction of impact on roadside living environment

In order to reduce the impact on the roadside environment, we are taking measures such as noise countermeasures by installing sound insulation walls and maintenance of environmental facility zones.In fiscal 2019, we installed sound insulation walls of about 3 km, and the total length of installation is about 1,080. It is km.

Forest formation that contributes to the prevention of global warming

Expressway fiscal 2019, we had planted trees on the expressway site in an area of approximately 3,700 ha. The CO2 absorption and fixation effect of these forests is estimated to be approximately 39,000 tons per year.
NEXCO EAST properly manages green infrastructure including these forests.

Reducing the impact on the natural environment

We carry out eco-road maintenance activities and eco-experiential learning, and work on greening activities and biotope conservation work in cooperation with local people.

Promotion of environment-friendly "eco Inter ^®" and "eco Area ^®"

At IC and SA / PA, based on the active introduction of energy-saving electrical equipment, measures to improve the efficiency of heating and cooling in buildings and the development of "environmentally friendly" facilities that utilize renewable energy such as solar power generation. Is proceeding.
