CO2 production refers to the process of emitting carbon dioxide, a greenhouse gas, into the atmosphere through various human activities such as burning fossil fuels, deforestation, and industrial processes. This research area focuses on understanding the sources and levels of CO2 emissions, as well as their impacts on climate change, air quality, and ecosystems. Researchers study ways to reduce CO2 emissions through renewable energy sources, carbon capture and storage technologies, and policy interventions to mitigate the effects of climate change and global warming.
