Environmental initiatives
NEXCO CENTRAL Has established an environmental policy, and through its business activities, has been working on the prevention of global warming, the promotion of 3R resources (reduction (reduction), reuse (reuse), recycle)), and consideration for the local environment is.
Suppressing global warming
Reduction of CO2 emissions related to business
高速道路に関連して排出されるCO2は、自動車交通によるものが大きな割合を占めています。一般道路より安定した速度で走行できる高速道路の整備が進むことで、自動車交通からのCO2排出が抑制されます。
Energy conservation initiatives
We are proceeding with the development of EV quick chargers, which are indispensable for promoting the spread of electric vehicles (EVs).
Expressway Improvement of forest on the slope
By planting trees on the slopes of Expressway, we are striving to restore the natural environment and improve the living environment, as well as curbing global warming. It is estimated that the approximately 1,730ha of forest area (equivalent to 360 Nagoya Domes) that has been maintained so far has absorbed and fixed CO 2 at approximately 18,300 tons per year.
Utilization of renewable energy
Renewable energy such as solar, wind, hydropower, geothermal, etc. is utilized for rest facilities and road facilities, and CO 2 We are working to reduce emissions.
Promotion of 3Rs for resources
Extending the life of tunnel lighting
When the old lighting equipment (sodium lamp) in the tunnel is renewed, it is replaced with a power-saving and long-life lighting fixture such as LED lighting.
Green recycling
We recycle plant-generated materials generated by pruning trees and cutting weeds on Expressway into compost and mulching materials. Compost is used as a soil conditioner for planting, and mulching material is effectively used to prevent weeds on slopes. The recycling rate in fiscal 2018 was 79%.
Recycling materials generated during cleaning
We separate garbage, earth and sand, and other waste generated by Expressway cleaning, and recycle items that can be recycled, such as glass bottles and PET bottles. Items that cannot be recycled are properly disposed of in accordance with the Waste Management and Public Cleansing Law.
Effective use of grown trees
The zelkova on the Tomei Expwy, which needs to be thinned 50 years after planting, has been transplanted between the newly constructed Shin-Tomei Expwy HamamatsuInasa JCT and Toyota-higashi JCT. We use trees that need to be cut down as valuable resources, and reduce planting costs for construction work.
Consideration for the global environment
Tree planting by local seedlings
In the section of the road that passes through an area rich in natural environment, the seeds of trees that grow naturally at construction sites, etc. are collected in advance and grown as local seedlings, Expressway We are developing greening methods to plant on the slope. To date, a total of approximately 840,000 local seedlings have been planted.
Creating eco-roads (roads that consider the natural environment)
The construction of Expressway may lead to the loss of habitats and growth bases for animals and plants in the surrounding area and the division of animal migration routes. At our company, we have created a biotope that artificially restores the habitat base of animals and plants, install a passageway that will be used as a path for animals, and adopt a waterway structure that allows small animals to crawl out even if they fall into the waterway. We are working to conserve biodiversity by building roads.
Explanation
A biotope is a habitat created or restored so that animals and plants can live forever.
