This study examines the effects of income levels on household greenhouse gas (GHG) emissions. For this aim, the impact of income level on household carbon footprints was analysed. Based on a largescale household survey in Ankara, direct and some indirect GHG emissions at the household level were estimated. Furthermore, the results were examined with the Environmental Kuznets Curve (EKC) Hypothesis which was studied in Turkey. Results showed that there is a significant relationship between household GHG emissions and income level groups. Depending on the level of income, consumption growth, and per capita, energy usage results in an increase in greenhouse gas emissions. Household average emission is found as 6.934 tons of CO2e per capita. Household carbon footprint varied across Ankara’s district according to income level. Wealthy districts usually have a higher per capita carbon footprint than poor districts. Besides the wealthiest socio-economic level was found to emit 1.87 times as much CO2e as the lowest. It is identified that emissions from heat production take the larger share of household carbon footprints. It is also determined that the only emission that decreases with higher income levels is indirect emissions from water consumption.

Gelir Düzeyinin Hanehalkı Sera Gazı Emisyonlarına Etkisi: Türkiye için Bir Vaka Çalışması

Öz

Bu çalışma, gelir düzeylerinin hane halkı sera gazı emisyonları (SGE) üzerindeki etkilerini incelemektedir. Bu amaçla gelir düzeyinin hane halkı karbon ayak izleri üzerindeki etkisi analiz edilmiştir. Ankara'da gerçekleştirilen geniş ölçekli bir hane halkı araştırmasına dayalı olarak, hane düzeyinde doğrudan ve bazı dolaylı sera gazı emisyonları tahmin edilmiştir. Diğer taraftan sonuçlar Türkiye için çalışılan Çevresel Kuznets Eğrisi (EKC) Hipotezi ile incelenmiştir. Buna göre hane halkı sera gazı emisyonları ile gelir düzeyi arasında önemli bir ilişki olduğu tespit edilmiştir. Gelir düzeyine, tüketim artışına ve kişi başına düşen enerji kullanımına bağlı olarak, enerji kullanımı sera gazı emisyonlarında artışa neden olmaktadır. Hane halkı ortalama emisyonu 6.934 ton CO2e olarak tespit edilmiştir. Hane halkı karbon ayak izi, Ankara ili genelinde gelir düzeyine göre farklılık göstermiştir. Genellikle yüksek gelire sahip ilçeler, düşük gelire sahip ilçelere göre daha yüksek kişi başına karbon ayak izine sahiptir. Ayrıca en yüksek sosyo-ekonomik düzeyin, en düşük sosyo-ekonomik düzeye göre 1.87 kat daha fazla CO2e saldığı tespit edilmiştir. Isı üretiminden kaynaklanan emisyonların hane halkı karbon ayak izi içerisinde en büyük paya sahip olduğu belirlenmiştir. Diğer taraftan gelir düzeyi yükseldikçe azalan tek emisyonun su tüketiminden kaynaklanan dolaylı emisyonlar olduğu da tespit edilmiştir.
