carbon pawprint

(名詞/可數) 碳爪跡 - 養寵物相關活動對大氣所排放的二氧化碳數量的測量。Cf. carbon footprint (碳足跡 - 人類活動對大氣所排放的二氧化碳數量的測量)。

引句:
Our dogs' carbon pawprints are largely related to their diets, with carbon-intensive ingredients such as meat being the main contributing factor … It has been estimated that the carbon pawprint associated with owning a medium sized dog is roughly twice that of running a typical SUV car, and the dogs in the USA are responsible for emissions equivalent to 13 million cars, or 64 million tonnes of CO2 per year.
