什么是“碳足迹”产品标签？
What is a product 'carbon footprint' label?
它标出产品从原料、制造、运输到废弃全过程的温室气体排放量（常折算CO2当量）。帮助消费者比较选择，但方法学与边界需透明以防误导。
It states a product's lifecycle GHG emissions (often CO2-equivalent) from material, manufacturing, transport to disposal. It helps consumers compare, but methodology and boundaries must be transparent to avoid misleading claims.

企业做“碳核算”一般遵循什么标准、分几步？
What standard and steps do companies generally follow for carbon accounting?
常遵循GHG Protocol：先确定组织边界与核算范围（1/2/3），再收集活动数据、乘以排放因子计算，最后核查与披露。数据质量是难点。
Usually GHG Protocol: set organizational boundary and scopes (1/2/3), collect activity data, multiply by emission factors, then verify and disclose. Data quality is the hard part.

什么是“基于消耗的”与“基于生产的”碳排放核算区别？
What is the difference between consumption-based and production-based emission accounting?
生产核算只计境内排放（含出口制造）；消费核算把进口商品隐含排放算给消费国，更反映最终责任。两者差额即贸易隐含碳转移，常由发展中国家流向发达国家。
Production accounting counts only domestic emissions (including export manufacturing); consumption accounting assigns embodied emissions of imports to the consumer, better reflecting final responsibility. Their gap is traded embodied carbon, often from developing to developed nations.
