As high frequency induction heating is powered completely by electricity, there are zero C2 emissions during use.
With the Japanese government’s October 2010 declaration of climate neutrality by 2050, businesses are beginning to set annual CO2 reduction goals.
Accordingly, many businesses are considering switching from gas furnaces and burners to high frequency induction heating.
Even within high frequency induction heating, many customers are considering switching from vacuum tube and thyristor converters to transistorized converters, which use less electricity and further contribute to reduced emissions.
Please see the following article for more details about CO2 reduction.

As high frequency induction heating only heats workpiece in the necessary area over a short time, it is highly energy efficient compared to furnaces that heat the air.
The efficiency is even greater with partial hardening of workpieces and hardening of large products.
Using a highly efficient transistor converter mitigates heat generation in the power supply due to energy loss, allowing for conservation of energy and cooling water required for machine cooling.
