Environmental Accounting
The Hitachi Construction Machinery Group conducts environmental accounting for major domestic and overseas production bases subject to consolidation aiming to continuously improve environmental activities by accurately ascertaining environmental conservation cost and environmental investment.
Our group performs environmental accounting in accordance with the Ministry of the Environment’s Environmental Accounting Guidelines 2005 edition.
Environmental conservation cost is calculated by totaling the cost of managing environmental facilities, research and development costs, and investment for environmental activities. Environmental conservation effect is comprised of economic outcomes evaluated in terms of both monetary value and quantitative outcomes evaluated based on the amount of reduction in environmental impact. The latter is divided into two stages for calculation: manufacture of the product and use of the product.
Regarding quantitative outcomes in the product usage stage, the quantity of environmentally sound products which will be recycled on site is estimated as an indicator of the contribution towards the materialization of a sustainable society.
