Environmental Data

Material Balance

In FY2003, Iwatani began surveying the environmental impact of Iwatani and consolidated Iwatani Group companies in Japan. Based on the results of this survey, we summarize and publish data concerning our use of resources and waste discharge in our activities as the material balance. We will use these data to assess our environmental impact and advance efforts to create a sustainable society.
We will continue to make efforts to minimize our environmental impact and engage in highly transparent information disclosure.

*Total figures on this page are rounded down and may not match the sums of individual figures.

*The items of data on material balance were changed in FY2023 in accordance with Environmental Reporting Guidelines 2018.

GHG Reduction Target

The Iwatani Group has announced its goal of achieving carbon neutrality by FY2050, targeting as a milestone to be reached by FY2030 reductions of 50% in CO2 emissions compared to FY2019 levels by the Iwatani Group in Japan.*1

FY2023 GHG emissions (Scopes 1-3)

  • *1 Materials balance and domestic Scope 1 and 2 figures are totaled for Iwatani’s domestic business sites, domestic consolidated subsidiaries, and two equity method affiliates that consume large volumes of energy.
  • *2 In some cases, estimates of water intake and wastewater are based on employee numbers or floor area weighted by rate of use.
  • *3 Overseas Scope 1 and 2 figures are totaled for Iwatani’s overseas business sites and overseas consolidated subsidiaries.
  • *4 Overseas CO2 emissions for FY2021 are indicated “-” under total because they were not published.
  • *5 Solar power includes PPAs.
  • Note : Underscored figures have been independently verified by SOCOTEC Certification Japan.

Contributions to CO2 reductions

In FY2023, we helped achieve reductions of approximately 750,000 t in CO2 emissions through LPG and LNG fuel conversion efforts, by supplying hydrogen for use in FCVs and FC buses, and by boosting sales of biomass fuel (PKS), biomass PET resins, Hydrocut®, premixed hydrogen-cutting gas and Bio-PP resin. We are committed to fighting global warming through proactive sales expansion efforts and the development of clean energy and other Solutions.

Biomass fuel (PKS) Contributing to CO2 emissions reductions (at the stage of use) by supplying PKS for power generation use
Biomass PET resins Contributing to CO2 emissions reductions through replacing traditional PET resins with resins made from plant-derived raw materials (at the stages of raw-material production and waste disposal)
