SEGES (Social and Environmental Green Evaluation System)

Assessing and clearly communicating the social and environmental values of corporate green spaces to create appealing spaces for stakeholders.

 The effects produced by greenery, even when they are individually small, provide a variety of functions to the environment, society and the economy.
 SEGES (Social and Environmental Green Evaluation System) evaluates and certifies the outstanding effects of these green spaces and green initiatives in order to help "assess and communicate the value" of corporate green spaces.

 Companies practicing green space conservation and environmental communication can get comprehensive and objective evaluation from a third-party organization of the social and environmental contributions as well as values. This third-party accreditation serves as a means of increasing stakeholder trust, sympathy and expectations.

    Adopting SEGES
  • (1) Enables the features and effects of green spaces to be visible and communicable

  • (2) Enables the relative evaluation of positive attributes and areas for improvement of green spaces and initiatives

  • (3) Enables effective investment in green spaces that leads to its sustainable management

  • (4) Makes it possible to assess and describe the progress of initiatives toward achieving the SDGs

 SEGES evaluates the above initiatives and makes their values more visible and communicable.

3 categories of SEGES sites

 SEGES has been in operation since 2005, evaluating and certifying good conservation and construction practices through SEGES OMA (OMAb and OMAf); evaluating excellent plans to conserve or create greenery during urban development since 2008 through SEGES PDC and certifying green spaces that have become valuable places for people to rest and relax in the urban environment, with the aim of raising awareness of the importance of green spaces, since 2013 through SEGES ESW. We have been able to achieve synergy by expanding our green collaborative network of participating companies.

 Certified sites fall under five stages of certification, depending on their current condition. For two years after a new certification, SEGES will conduct maintenance audits, document review, to check the maintenance stage of green spaces. On the third year, a renewal audit with onsite inspection in carried out, similar to a new certification. The renewal auditing period is an opportunity to be promoted to a higher stage of certification.

 Furthermore, several companies have been able to sustain, develop and expand their “Superlative Stage” certification over many years. To endorse such efforts, which immensely contribute to increasing the value of green spaces, and to widely communicate their outstanding social and environmental contributions through greenery to the public, we launched a new “Green Legacy” category within the “Operation, Maintenance and Active use”.

SEGES ESW (Environmental friendliness, Safety and Well-being)

fig_3 types of SEGES sites  Urban Oasis certification started in 2013 and is now on its eighth year. Green spaces that have been installed or managed by private businesses and contribute to society and the environment are evaluated based on three certification criteria: (1) openness to the public, (2) safety and (3) environmental friendliness, and are certified by the SEGES Evaluation and Certification Committee.
 Greenery that provides an oasis to people and serves as a habitat for small creatures are natural spaces that are a vital part of our lives. Now that we are being forced to reconsider our current lifestyles, we are realizing how such green spaces have long provided social and environmental benefits, and have become a "third place," a haven of rest that fits our new normal.

SEGES PDC (Planning, Designing and Construction)

fig_3 types of SEGES sites  For businesses with urban development or building construction plans, we evaluate and certify their greening plans or projects that create excellent green spaces for society and the environment.
 As an objective assessment, this certification allows businesses to clearly present their commitment and efforts toward the development of community with lush greenery to customers and local people.
    Content of evaluation:
  •  How does it conserve nature, the environment and culture of the area?

  •  Is the plan based on a unique concept?

  •  Is it an environmental greening plan that will lead to increasing the value of properties?
