Günlük Ulaşımda Bireysel Davranış Değişiminin Karbon Ayak İzi Üzerindeki Etkisi: Iğdır Örneğinde Bisiklet Kullanımına İlişkin Uygulamalı Bir Çalışma

Öz

Bu çalışma, bireysel ulaşım tercihlerindeki davranışsal değişimlerin karbon ayak izi üzerindeki etkisini öz-gözlemsel bir vaka analizi aracılığıyla sunmaktadır. Teorik olarak, Planlı Davranış Teorisi ve Değer–İnanç–Norm Kuramı çerçevesinde bireysel eylemin motivasyonel temelleri açıklanmaktadır. Araştırma, Türkiye’nin Iğdır ilinde yaşayan bir kamu çalışanının yaklaşık iki ay boyunca özel araç kullanımını bırakarak bisiklete geçişini ele almakta ve bu geçişi nicel verilerle destekleyerek çevresel, ekonomik, hava kirliliği ve sağlık açısından analiz etmektedir. Katılımcının haftalık 145,52 km’lik bisiklet kullanımı sonucunda yaklaşık 21,43 kg CO₂e salımı engellenmiş ve 7,999 litre yakıt tasarrufu sağlanmıştır. Ayrıca fiziksel aktivite düzeyi Dünya Sağlık Örgütü standartlarına uygun hâle gelmiştir. Bu bağlamda çalışma, bireysel düzeydeki düşük karbonlu ulaşım uygulamalarının kolektif iklim hedeflerine katkı potansiyelini vurgularken, yerel yönetimlerin eksikliklerine dikkat çekmekte ve politika önerileri sunmaktadır.

The Impact of Individual Behavioural Change in Daily Transportation on Carbon Footprint: An Applied Study on Bicycle Use in the Case of Iğdır

Öz

This study presents the impact of behavioural changes in individual transportation preferences on the carbon footprint through a self-observational case study. From a theoretical perspective, the motivational underpinnings of individual action are explained within the framework of the Theory of Planned Behaviour and the Value–Belief–Norm Theory. The study focuses on a public employee living in Iğdır Province, Türkiye, who, over a period of approximately two months, switched from private cars to bicycles. This transition is analysed using quantitative data regarding environmental, economic, air pollution, and health aspects. As a result, the participant's weekly cycling distance of 145.52 km led to the prevention of approximately 21.43 kg of CO₂e emissions and the saving of 7,999 litres of fuel. Moreover, their physical activity level met World Health Organization standards. Overall, the study highlights the potential for low-carbon transportation practices at the individual level to contribute to collective climate goals, while also emphasizing the shortcomings of local governments and providing policy recommendations.
