I'm looking for studies comparing the environmental impact of solar direct drive ice-lined refrigerators versus vaccine refrigerators using grid-electricity, kerosene and gas. Or cradle-to-grave, Life cycle analysis of SDD ILR's versus these other types of refrigerators.
Basically to answer the questions:
1) What are average CO2 emissions (savings) over a 10-year lifespan during the use-phase of these refrigerators?
2) Is there any CO2 emission saving or improvement in Greenhouse warming potential, over the total life span of these refrigerators (including the emissions produced during production of the refrigerators and photovoltaic cells, and end-of-life disposal).
This is in support of research I'm conducting into sustainable procurement of cold chain equipment.
