HCM Group Participating in the Light-down Campaign


Nine sites of five Hitachi Construction Machinery Group companies participated in the light-down campaign implemented by the Ministry of the Environment.

The campaign slogan is “expressing gratitude to the earth on the night of the light-down campaign.” The event was held on June 22 (summer solstice) and July 7 (Cool Earth Day). The lights were turned off from 20:00 to 22:00 on these days to fight climate change.

The HCM sites that participated in the campaign turned off their lights, including billboard lights. In addition, we established an expanded implementation period. From May to October we aim to curb our electrical used by a total 32,375kWh or about 18 tons of CO2 emissions*1 (this is equivalent to the amount of CO2 absorbed by roughly 1,274 cedar trees*2).

The HCM Group is contributing to the prevention of climate change by promoting energy conservation measures, including the light-down campaign, and reducing CO2 emissions throughout the entire lifecycle of our products. Going forward, we aim to conduct business activities that aim to achieve a sustainable society.
