1. Introduction Carbon reduction is a critical solution to climate change, and reducing greenhouse gas (GHG) emissions is key to mitigating global warming and ensuring a sustainable future. According to the “Special Report on Global Warming of 1.5 °C”, released by the Intergovernmental Panel on Climate Change (IPCC) in 2018 to support the goals of the Paris Agreement [1], carbon emissions (CEs) must reach zero by 2050 to maintain the global average temperature rise below 1.5 °C.
