Environmental Data
Material Balance
The material balance provides an overview of our environmental impact. In FY2003, Iwatani began surveying consolidated Group companies in Japan for their environmental impact and publishing the results. Our goal is to improve environmental efficiency in our business activities by reducing resource inputs, energy consumption, waste outputs, energy-derived CO2 emissions, and other environmental impact factors.

Contributions to CO2 reductions
In FY2022, we helped achieve reductions of approximately 560,000 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, and Hydrocut® premixed hydrogen-cutting gas. We are committed to fighting global warming through proactive sales expansion efforts and the development 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 |
