Reducing Greenhouse Gases Emitted in the Value Chain

Measures to Comply with GHG Protocol Scope 3

The Mitsubishi Electric Group refers to regulations such as the Greenhouse Gas (GHG) Protocol – an international standard for the calculation of greenhouse gas emissions – and the Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain, published by Japan's Ministry of the Environment, to determine how to assess and calculate emissions from business activities (Scope 1 and 2) and indirect emissions from outside the range of its business activities (Scope 3).

Owing to the fact that around 80% of emissions in the value chain are greenhouse gas emissions associated with the use of sold products (Scope 3, Category 11), the Mitsubishi Electric Group focuses on developing highly energy-efficient products that are linked to reducing greenhouse gas emissions during product usage. At the same time, we strive to continuously reduce CO2 emissions during production, as well as emissions of other greenhouse gases with greater global warming potential than CO2.
