Without reducing the greenhouse gases through drastic action today, adapting to these untoward effects of it will be challenging and costly. Therefore, estimation of the green-house gases is a prime importance. However, there are no studies conducted in South Asian households and individuals partly due to the non-availability of a validated tool.  Therefore, this study aims to validate a screening tool to assess the carbon footprint (CFP) of residents in a Sri Lankan household (HH). The 28-item Resources and Energy Analysis Program (REAP) Calculator which was originally developed in United Kingdom was initially translated, population specific adapted using modified Delphi process with a panel of 10 experts and assessed for judgmental validity. Construct validity was assessed among 210 HHs by performing exploratory factor analysis and confirmatory factor analysis. Reliability was assessed using the test-retest method and internal consistency. After four rounds of Delphi techniques and validation, 20-item CFP-SL tool was found to be valid and reliable for assessing the CFP both urban and rural HHs. Five-factor model of 20 items was identified as explaining 64.3% of the total observed variance. It showed a stable factor structure (RMSEA=0.181, CFI=0.850, NNFI=0.813, SRMR =0.085, GFI=0.643) and reliability (internal consistency of 0.87). Therefore, Sinhala version of the CFP-SL tool is a valid and reliable tool to assess the CFP in urban and rural Sri Lankan HHs.</p> <p> </p>}, number={1}, journal={American Scientific Research Journal for Engineering, Technology, and Sciences}, author={Kalubowila, Kasuni and Karunaratne, Parakrama and Yapa, Buddhika and Arambepola, Carukshi}, year={2022}, month={Apr.}, pages={45–57} }
