Studying the product carbon footprint can help enterprises to formulate effective carbon emission reduction plans，contributing to the achievement of green transformation. In terms of evaluation standards，there are already mature and applied product carbon footprint evaluation standards in foreign countries with an early start，while China has released industry standards，local standards and group standards related to product carbon footprint with limited types of products. In terms of evaluation process，the product carbon footprint evaluation process at home and abroad is basically the same，mainly including three steps：determination of evaluation goals，carbon footprint accounting，analysis and improvement. In terms of application，the development of product carbon footprint abroad is relatively mature，while domestic product carbon footprint is still in the pilot stage with overall low popularity and accounting rules and supervision to be further improved. In order to promote the development and application of product carbon footprint in Fujian Province，it is recommended to establish and improve the product carbon footprint standard system，consolidate and improve the evaluation and supervision system for product carbon footprint，and pilot to promote the application of product carbon label.
