也許大大可以在以上網站發表些論述,改變一下他們的想法,給予我們正確的知識.
生產每公斤咖啡產生的co2平均為1.52公斤,相當於一輛汽普通汽車行駛5.8公里
減少生產咖啡碳足跡排放是現在正在研討的議題,或許未來會有科技咖啡名詞的出現.

To calculate Santropol Coffee Roasters' footprint, Taking Root measured the following business activities:
•The transportation of coffee beans by land and sea from the coffee
plantations to the roaster in Montreal;
•The natural gas used during the daily operations of the roaster;
•The gas used by the roasters' vehicles; and
•The distribution of roasted coffee to retailers in Quebec.
Overall, importing, roasting and distributing one kilogram of coffee generates an average of 1.52 kg of CO2. This is like driving a standard-sized car for 5.8 km.
With this carbon footprint analysis, Santropol Coffee can identify ways to further reduce its footprint before offsetting its unavoidable emissions.
