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.

[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.

Implementation plan for reducing greenhouse gas emissions, etc.

In March 2023, we formulated the Greenhouse Gas Emissions Reduction Plan (hereinafter referred to as the ``Plan''), which aims to reduce greenhouse gas emissions by 50% or more by 2030.

Plan overview

This plan covers the office work (hereinafter referred to as "office activities") and business conducted by our company.
In addition, among our business activities, we are promoting initiatives to reduce greenhouse gas emissions in office activities in advance, and in future projects such as Expressway construction and management, we are implementing a carbon neutral plan by fiscal 2050. We will formulate the following and promote initiatives from 2024 onward.

Goals for reducing greenhouse gas emissions

Our goal is to reduce greenhouse gas emissions by more than 50% by fiscal 2030, based on fiscal 2013.
This target will be appropriately reviewed if further reduction is possible, taking into consideration the progress of our efforts and the status of greenhouse gas emissions.

Main goals of the initiative

1. Introduction of solar power generation
   We install solar power generation when constructing or renovating buildings used for office activities.
2. Introduction of buildings with ZEB (Net Zero Energy Building) specifications
   Regarding buildings used for office activities, we aim to introduce specifications equivalent to ZEB Ready for newly constructed or renovated buildings by 2030.
3. Introduction of electric vehicles
   Vehicles used for office activities ^* We will introduce all electric vehicles (hybrid vehicles, electric vehicles, fuel cell vehicles, plug-in hybrid vehicles) by 2030.
   • Excludes vehicles used in times of disaster, etc.
4. Introduction of LED lighting
   We aim to have 100% indoor lighting installed in buildings used for office activities by fiscal 2030.
5. Procurement of renewable energy electricity
   We aim to procure at least 60% of the electricity used for office activities from renewable energy sources.

In order to achieve the goals of the above initiatives, we have formulated "Rules of Conduct for Reducing Greenhouse Gas Emissions [PDF: 290KB]" for each employee to work towards.

[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.
