In the future, whenever consumers buy high-tech gear, home appliances, or even soft drinks, they will find a "carbon footprint label" on the package, which will indicate how many grams or kilograms of CO2 (or its equivalent) the product will produce over its complete life cycle.
未來，消費者無論購買 3C、家電、甚至飲料時，都可能看到一張畫著腳丫子等圖形的「碳足跡標籤」，上面標示著這個產品整個生命週期將耗用幾公克或幾公斤的二氧化碳（CO2）。
