Climate Emergency Declaration: Obtained SBT Net-Zero Target Certification to Achieve “Net-Zero by 2050”
Certified by a third party as being consistent with the Paris Agreement and based on scientific evidence

Nikken Sekkei Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Atsushi Omatsu; President and CEO; hereinafter “Nikken Sekkei”) has been certified by the “Science Based Targets Initiative” (hereinafter “SBTi”), an organization that certifies greenhouse gas emission reduction targets—“Science Based Targets” (hereinafter “SBT”)—that are scientifically aligned with the goals set forth in the Paris Agreement.※1We are pleased to announce that we have been certified to meet the corporate net-zero target.

Certified Emissions Reduction Targets (Nikken Sekkei Group)

This marks the first time a comprehensive domestic design firm has been certified for a corporate net-zero target. (Certification date: November 2025)

SBT is a greenhouse gas emissions reduction target aligned with the Paris Agreement, which aims to limit global temperature rise to well below 2°C above pre-industrial levels and to pursue efforts to limit the increase to 1.5°C.
In 2021, Nikken Sekkei issued a “Climate Emergency Declaration,” through which the company, as a private-sector entity, seeks to balance economic activity with the realization of a decarbonized society and to engage with society on this issue.※2The company announced its goal of achieving net-zero by 2050. This means that the GHG (greenhouse gas) emission reduction targets set to achieve this goal have been certified by a third party as being based on scientific evidence.

Recently, “reduction contribution” has been gaining attention as a metric for evaluating companies’ ability to address the challenge of reducing GHG emissions.According to guidance from the WBCSD (World Business Council for Sustainable Development), obtaining Science-Based Targets (SBT) is cited as a criterion for a company’s “eligibility” to claim emission reduction contributions, and achieving SBT status is regarded as the basis for a company to publicly declare its environmental contributions. For more information on emission reduction contributions, please refer to our press release.

Nikken Sekkei will continue to publish its sustainability report※3We will disclose our greenhouse gas emissions and strive to ensure that reductions are steadily implemented in accordance with our established targets.
