CASBEE® (Comprehensive Assessment System for Built Environment Efficiency) is an evaluation system that ranks buildings and structures in terms of their environmental performance. In addition to each building's ability to reduce its environmental impact across a variety of areas including energy and resource conservation as well as recycling, this system comprehensively evaluates the environmental performance of each building and structure including its aesthetic appeal.

Under the DBJ Green Building system, the Development Bank of Japan (DBJ) certifies real estate properties with high environmental and social awareness, based on five evaluation ranks (one star "★" to five stars "★★★★★"), using a comprehensive scoring model developed independently by DBJ.

BREEAM is a holistic framework for assessing sustainability within the global built environment developed by the Building Research Establishment. BREEAM certification is available internationally for asset owners and developers engaged in any phase of the built environment, from infrastructure to new builds, refurbishments, fit outs, and existing buildings. Data is collected across nine categories, with an emphasis on whole-life carbon, biodiversity, resilience, and material selection. Successfully certified projects achieve a rating of either Pass, Good, Very Good, Excellent or Outstanding.

BELS certification is provided under a public evaluation system, which evaluates the energy conservation performance of non-residential buildings. In the BELS system, five levels of energy conservation performance are evaluated by a third party based on various criteria, irrespective of whether they are new buildings or existing buildings. BELS certification, which is the first public evaluation system specific to energy conservation performance in Japan, is expected to promote further improvements by providing appropriate information and promoting the energy conservation performance of buildings.

ABINC is a certification system to evaluate and certify biodiversity-friendly initiatives based on the “Promotion Guidelines for ABINC” developed by General Incorporated Association Japan Business Initiative for Biodiversity (JBIB), and no certification rating is assigned.
