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.

Contributions to CO₂ reductions

Through fuel conversion to LPG and LNG, supplying hydrogen for fuel cell vehicles and fuel cell buses, and expanding sales of biomass fuel (PKS), biomass PET resin, Hydrogen-based premixed cutting gas (Hydrocut®), and biomass PP resin, we contributed to a CO₂ emissions reduction of approximately 780,000 tons in FY2024. We will continue contributing to global warming prevention through proactive efforts to develop and expand sales of clean energy and other solutions

Product, service	Reduction concept
LPG and LNG fuel conversion	Contributing to CO₂ emissions reductions (at the stage of use) through conversion from heavy oil and other fuels to LPG and LNG
Supplying hydrogen for FCVs and FC buses	Contributing to CO₂ emissions reductions (at the stage of use) by supplying hydrogen as fuel for FCVs and FC buses
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)
Hydrocut® premixed hydrogen-cutting gas	Contributing to CO₂ emissions reductions (LCA) via the replacement of acetylene and other cutting gases with hydrogen-mixed Hydrocut® gas
Bio-PP resins	Contributing to CO₂ emissions reductions during production, disposal, and incineration (at the stages of raw material production and waste disposal) by replacing traditional PP resins with resins made from plant-derived raw materials
