In February 2021, following Kajima's nomination on the CDP "A List" for climate change in December 2020, we have been selected for the Leaderboard, the top-rank designation in the CDP Supplier Engagement Evaluation (SER) by CDP (headquartered in London, UK), a nonprofit organization committed to environmental investigations and information disclosure.

We actively promote the reduction of CO₂ emissions during construction, and pursue the spread and expansion of energy-saving designs and zero energy buildings (ZEB) under the Kajima Environmental Vision: Triple Zero 2050. We have also been developing and introducing low-carbon construction materials in collaboration with construction material manufacturers.
