Carbon Neutrality

ISO14068（Carbon Neutrality)● Carbon Neutrality
Residual Emissions＝ Removal enhancement＋Offset
・DAC, DAC-U, CCS, CCSU, BECSS● Transitional state: Hierarchy Approach

・NETs：Negative Emission technologies

・Avoidance： Change portfolio
・Reduction： Energy saving, Renewable, Purchase low carbon products
・Offset (purchase carbon credit)● NO Avoided emissions

Our DAC-U projects and LCA

We would calculate•How much we can reduce CO2 by our DAC-U.

At the start point of the projects,
We would establish the methodology to calculate
CO2 emissions.
