Formulation of Guideline for Quantifying GHG Emission Reduction Contribution

In December 2017, The Ministry of Economy, Trade and Industry (METI) established the Study Group for Greenhouse Gas Emission Reduction Contribution through Global Value Chain, and the study group discussed points of views for quantifying and clarifying GHG emission reduction contribution by the industry through the dissemination of environmentally-friendly products and services.

Based on the results of the discussions by the study group, METI formulated the Guideline for Quantifying GHG Emission Reduction Contribution.

1. Background

Making efforts to disseminate environmentally-friendly products and services and thereby contribute to GHG emission reduction through the global value chain is an important approach for industry to deal with climate change. In order for industry to be aware of its own potential in reducing GHG emissions, and to promote further efforts to that end, it is important for industries to quantitatively evaluate their initiatives and contributions, and to make these evaluations public.

The study group, which was established in December 2017, discussed this issue and formulated a general guideline to conduce industries to quantify their GHG emission reduction contributions and to explain them to the public in a convincing way.

2. Outline of the Guideline

(1) Purpose

The guideline shows the basic idea for quantifying and clarifying each business's GHG emission reduction contribution through the dissemination of products and services via the global value chain. It is expected to be referred to when businesses quantify contributions of their products and services and explain their contributions and efforts to stakeholders.

(2) Key points of the Guideline

  • The basic idea has been compiled by reference to quantification methods already adopted by businesses and the industry.
  • An approach to evaluate GHG emission reduction contribution of respective products and services is presented, covering the entirety of their life cycles from material procurement to disposal or recycling.
  • The difference in GHG emissions between the case of supplying the relevant products and services and the case of supplying other products and services is to be quantified as emission reduction contribution.
  • The Guideline presents points to note for referring to data of emission reduction contribution thus quantified in explanation to the stakeholders.
