Responding to Climate Change
At Global Eco Vision 2020, we have set a basic unit target for CO2 emissions and have been working to reduce energy consumption and the associatedCO2 emissions. In the newly formulated Eco Vision 2030, we will work to reduce the total amount on the premise of aiming for carbon neutrality in
2050.
