Reduction of Greenhouse Gas Emissions

In accordance with “the Act on Promotion of Global Warming Countermeasures”, we collect data on the emissions of carbon dioxide (CO2) and other greenhouse gases from all of our business establishments, including our plants, laboratories, and head office and report this data to the national government. In FY2016, we were able to reduce GHG emissions from energy use and non-energy use because we changed fuel and feedstock for manufacturing ammonia from naphtha to natural gas with fewer GHG emissions. The GHG emission rate, which is calculated as the ratio between emissions and sales (emission / sales), fell steadily over the course of six years from FY2011 to FY2016. In FY2016, the GHG emission rate was reduced to 78% compared to the FY2011 level.

Calculation of Scope 3 Emissions: Indirect Emissions of Greenhouse Gas (GHG) via the Supply Chain

To discover our GHG emissions throughout the supply chain, from the purchase of raw materials to use and disposal by customers, we calculated our indirect GHG emissions via the supply chain (Scope 3 emissions) in addition to our direct GHG emissions (Scope 1) and indirect emissions derived from energy (Scope 2). As a result of the calculations of our Scope 3 emissions based on the Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain (Ver. 2.2) and Database of Emissions Unit Values for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain (Ver. 2.4) provided by the Ministry of Economy, Trade and Industry and the Ministry of the Environment of Japan, we found that emissions from purchased goods and services accounted for 90% of all the items that were included in the calculation.
