LY/T 3197-2020Technical regulations for carbon accounting of bamboo products (English PDF)

Foreword

This standard is compiled in accordance with the provisions of GB/T 1.1-2009.

This standard was proposed and managed by the National Bamboo and Rattan Standardization Technical Committee (SAC/TC263).

Drafting organizations of this standard. International Center for Bamboo and Rattan, Department of Ecological Protection and Restoration, National Forestry and Grassland Administration, Forest Health Research Institute of Ecological Environment and Protection, Chinese Academy of Forestry Research Institute of Forestry, Hebei Agricultural University.

Introduction

Assuming that the carbon emission of bamboo products is a first-order decay function (that is, the constant ratio of the annual loss of bamboo products to its carbon storage) Carbon reserves left in "bamboo products in use". When compiling the bamboo national greenhouse gas inventory, the production method is used to calculate the carbon change of bamboo products, the export of bamboo products is regarded as carbon emission, and the import of bamboo products is regarded as carbon absorption. When the bamboo products are finally consumed in the importing country to waste decomposition, their carbon Emissions are included in the country where the product is consumed. Assuming that the bamboo products produced in the current year will begin to attenuate and release from the next year, the annual attenuation ratio is fixed, and the decomposition the rate is equal to the reciprocal of the service life, and the service life of various bamboo products depends on the specific product use.

Carbon metering regulations for bamboo products

1 Scope

3 Terms and definitions

The following terms and definitions apply to this document.

Bamboo products

Products made with bamboo as the main raw material.

Lifespan

Refers to the period from the production of the final product to the normal use or usable state before being recycled or processed. It is the use time or average of the product.

Both use time.

Carbon stock

The amount of carbon storage of a certain bamboo product in the product library.

Carbon stock-change

The amount of change in the carbon storage of bamboo products during use or storage for a period of time.

Decay rate

The ratio of the annual loss of bamboo products due to wear or natural decomposition during use or storage to its carbon storage, its value, etc.

It is the reciprocal of service life.

4 Classification of bamboo products

Refer to LY/T 2608-2016, and select the main categories that have a substantial contribution to carbon storage based on the difference in service life.

It is raw bamboo, board, bamboo charcoal for adsorption, bamboo paper or cardboard, and bamboo daily necessities.
