Response to Climate Change

Greenhouse Gas Emissions Across the Value Chain

As climate change becomes an increasingly serious issue, companies must monitor and manage not only their own GHG emissions but also emissions generated across their entire value chain. Based on the GHG Protocol*¹, which provides international standards for calculating GHG emissions, and the Ministry of the Environment's Basic Guidelines for Calculating GHG Emissions throughout the Supply Chain, Toshiba Group monitors and calculates indirect GHG emissions generated outside the scope of its own business activities (Scope 3) in addition to its own emissions (Scope 1 and 2). Toshiba Group will continue working effectively throughout product lifecycles by quantitatively analyzing emissions accordingly.
Category 11 (GHG emissions through the use of sold products) accounts for a high percentage of emissions across the value chain. We will therefore continue to promote the development of energy technologies to realize decarbonization and to improve the energy efficiency of products. We are also cooperating with suppliers to reduce Category 1 (GHG emissions through the use of purchased products and services). Going forward, we will consider calculating GHG emissions using data obtained from our main suppliers.
GHG emissions through the use of sold products account for a high percentage of emissions across the value chain. We will therefore continue to promote the development of energy technologies to realize decarbonization and to improve the energy efficiency of products.

Methods of Calculation

CO₂ emissions caused by use of fuels: Calculated by the method set by Toshiba Group based on the Ministry of the Environment's Manual for Calculating and Reporting GHG Emissions (Version 4.9)
CO₂ emissions coefficient for electricity purchasing: Provided by each power company
Greenhouse gases other than CO₂: Calculated by the method set by Toshiba Group using the Global Warming Potential (GWP) in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC)
CO₂ emissions caused by use of products sold: Calculated by aggregating the emissions estimated to be generated during use of products in the future for the year the products were sold
