Promoting Environmentally Friendly Road Development
Contributing to Preventing Global Warming
In addition to improving the flow of traffic by advancing the expressway network and taking measures to ease traffic congestion, we are planting greenery on roadside slopes and introducing energy-saving technology to reduce carbon dioxide emissions, which contribute to the prevention of global warming.

Contributing to a Recycling-oriented Society
We contribute to the formation of a recycling-oriented society, through the recycling of construction byproducts produced from the business activities of the operation & management and construction of expressways, the recycling of trash and plant-derived materials collected at expressways and rest areas, and the promotion of green procurement.

Example of reusing plant-derived materials after composting
Reducing the Burden on the Environment
We are striving to reduce the adverse effects of expressways on the environment in every step of business activity by setting up environmentally friendly roads (eco-roads) and noise barriers, planting trees, and taking other measures to preserve the environment for those living along the routes of expressways.

Developing Technologies for Preserving the Environment
In order to use plant-derived materials produced from the mowing of grass, pruning of trees, etc., we have been working on practical applications for electric power generation from biomass gas at Nasukogen rest area on Tohoku Expressway (inbound).NEWS RELEASE(August 4, 2016)【PDF：1.4MB】
Electric power generation from biomass gas using plant waste
Taking New Steps for the Future of the Environment
We installed quick charging stations for electric cars at rest areas where NEXCO East Group provides services, so that our customers who use electric cars can feel at ease when using the expressways. We are continuing to develop the stations.
