Actions to Tackle Climate Change

Idemitsu Group GHG Reduction Target

The Paris Agreement sets a goal of "keeping global average temperature rise well below 2°C compared to before the Industrial Revolution." To achieve this goal, GHG emissions made by human has to be “Net zero” in the second half of this century. People around the globe are required to work toward achieving this goal from the standpoint of society. Since oil companies mainly supply fossil fuels; source of GHG emissions, our efforts to reduce the emissions have drawn public attention.

Idemitsu Group GHG Emissions

Since CO2 accounts for over 90% of Japan’s GHG emissions, CO2 becomes our main concern. As shown in Fig. 2, the amount of Scope 3 is much larger than Scope 1 and Scope 2. For this reason, we believe it is important to reduce GHG emissions throughout the value chain, including Scope 3 as well as reducing Scope 1 and 2 emissions from the use of energy required for in-house production activities.

  • Unit:million ton
Description Emission 
Scope1 Direct emissions from our business sites (mining sites,refineries, and plants) 13
Scope2 Indirect emissions from purchased electricity and other sources of energy 1
Scope3 Others (emissions from fuel oil products used by the society and services provided by other companies) 142
  • *”World” and “Japan” emissions are calculated based on Scope1 and 2

Idemitsu Group’s Efforts in Reducing GHG Emissions

As our basic concept of GHG reduction is to promote simultaneous contribution to each field; environment, society, and economy, we set the three indicators below and work to reduce the emissions.

Target Value
  • (Compared to 2017)
  Description Target Value Target Year
① Scope 1 & 2 Reduction Reducing emissions through promotion of  energy conservation activities at our refineries and plants ▲2 mill tons of CO2 (▲15%) 2030
Monitoring Indicator:Monitoring the transition of low carbonization
  • (Compared to 2017)
  Description Indicator Level Target Year
② Low Carbon Level of Supplied Energy Reduction of the “CO2 emissions per unit of energy” supplied to society ▲30% 2050
③ Degree of carbon exit from corporate earnings Raising the “Revenue level per unit of CO2    
  • Idemitsu Group’s GHG reduction target focuses on CO2.
  • Monitoring indicator ② & ③ includes Scope 1, 2, & 3.
  • We will revise the indicator level as needed while monitoring trends in low carbon energy demand by society.

[Initiatives to Reduce GHG Emissions]

We will promote contribution to the reduction of CO2 emissions through our business activities in the following five areas.


Presenting Idemitsu Kosan’s Biomass Business at the ASEAN Bioenergy and Bioeconomy Conference

On June 6, the “ASEAN Bioenergy and Bioeconomy Conference 2019” hosted by Kasetsart University was held in Bangkok. Invited by the university, our engineer from Coal Coal Business Department gave a lecture on the technology of semi-carbonizing wood pellets (black pellet). Currently, Idemitsu Kosan is working on black pellets production in Thailand.

During the event, we had an active opinions exchange with local biomass-related companies, and many participants expressed their expectations to Idemitsu as we presented our plan regarding biomass commercialization.
