KURUMSAL YÖNETİM GÖSTERGELERİNİN SERA GAZI EMİSYONLARINA ETKİSİ: BORSA İSTANBUL’DA BİR ARAŞTIRMA

Öz

Çalışmanın amacı, kurumsal yönetimin sera gazı emisyonlarına etkisini araştırmaktır. Bu amaçla BIST Sürdürülebilirlik Endeksi’nde yer alan 84 şirketin 2015-2023 dönemi verileri kullanılarak panel veri analizi ve logit analizi gerçekleştirilmiştir. Bu çalışmada kurumsal yönetim göstergeleri kapsamında yönetim kurulu büyüklüğü, yönetim kurulu bağımsızlığı, yönetim kurulu kadın üye oranı, yönetim kurulu toplantı sayısı, CEO ikiliği ve çevre / sürdürülebilirlik komitesi varlığı değişkenleri ele alınmıştır. Çalışma bulgularına göre çevre veya sürdürülebilirlik komitesine sahip işletmelerde toplam emisyonların azaldığı ve Karbon Saydamlık Projesi (CDP) anketine yanıt verme olasılığının arttığı gözlenmiştir. Bununla birlikte yönetim kurulu büyüklüğünün toplam emisyonlar üzerinde pozitif, kapsam 2 emisyonları üzerinde ise negatif yönde etkili olduğu belirlenmiştir. Buna karşın yönetim kurulu bağımsızlığı, kadın üye oranı ve toplantı sayısının sera gazı emisyonları ile CDP anketine yanıt verme davranışı üzerinde anlamlı bir etkisi bulunmamıştır.

THE IMPACT OF CORPORATE GOVERNANCE INDICATORS ON GREENHOUSE GAS EMISSIONS: EVIDENCE FROM BORSA ISTANBUL

Öz

The aim of this study is to examine the effect of corporate governance on greenhouse gas emissions. For this purpose, panel data analysis and logit analysis were performed using data from 84 companies listed in BIST Sustainability Index for the period 2015-2023. In this study board size, board independence, the percentage of female board members, the number of board meetings, CEO duality, and presence of an environment/sustainability committee were examined as corporate indicators. According to the findings of the study, it was observed that total emissions decrease and the likelihood of responding to the Carbon Disclosure Project (CDP) questionnaire increases in firms that have an environmental or sustainability committee. However, it was determined that board size had a positive effect on total emissions and a negative effect on Scope 2 emissions. In contrast, board independence, the proportion of female board members, and number of board meetings were not significantly associated with greenhouse gas emissions or the likelihood of responding to the CDP questionnaire.
