Water efficiency vs climate change: an estimation of carbon generation in 2100 from showers for bathing in Hong Kong

Brief:

This study reports the estimates of CO2 emissions for projected warming by 2100 attributed to hot showers by Hong Kong residents. The results show that for an ambient temperature increment of up to 5°C in the base case, CO2 emissions from showers for bathing today and in 2100 are compatible (i.e. -3% to 5%). However, the use of low flow showerheads can reduce CO2 emissions by around 25%.
