Environmental Accounting

Lintec uses environmental accounting to ascertain the costs and benefits of environmental protection, and continues to carry out environmental protection activities as effectively as possible. Environmental investments*1 made in fiscal 2018 totaled 350 million yen, while environmental costs*2 incurred for the same year totaled 2,648 million yen. The total environmental investments, used to introduce new gas cogeneration systems, among others, decreased by 285 million yen from the previous year. The total environmental costs increased by 17 million yen year on year.

  • *1 Environmental investments: The amount of investments made during a year for the purpose of environmental conservation. Since the effect of the investments lasts for several years or longer, the invested amounts are recognized as costs over those years.
  • *2 Environmental costs: Costs or losses arising from consuming goods and services for the purpose of environmental conservation
