GB/T 24045-2024Environmental management - Eco-efficiency assessment of product systems - Principles, requirements and guidelines (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is equivalent to ISO 14045:2012 "Principles, requirements and guidelines for eco-efficiency assessment of environmental management product systems".

Introduction

Eco-efficiency assessment is a quantitative management tool that can be used to study the environmental impact of a product system during its life cycle and the Value to stakeholders.

In the eco-efficiency assessment, this document uses the life cycle assessment (LCA) method specified in ISO 14040 and ISO 14044 to evaluate the environmental Therefore, eco-efficiency assessment is consistent with the important principles of life cycle assessment, such as life cycle perspective, comprehensiveness, functional Units, iteration, transparency, and the priority of the scientific method.

The selection of product system value can be used to comprehensively reflect its resource, production, delivery or use efficiency. The value can be expressed in terms of currency or other value aspects.

To express.

The main purposes of this document are to.

--- Establish clear terminology and a common methodological framework for eco-efficiency assessment;

--- Realize the practical application of eco-efficiency assessment of various product (including service) systems;

--- Provide clear guidance for the interpretation of eco-efficiency assessment results;

--- Encourage transparent, accurate and informative reporting of eco-efficiency assessment results.

Eco-efficiency assessment of environmental management product systems Principles, requirements and guidelines
