Continuous carbon dioxide emissions have resulted in a slew of environmental issues in recent years, including global warming and regular bouts of exceptionally severe weather. As a result, carbon emission reduction has become a major issue for all countries throughout the world, and green development has become an important factor in driving global economic change.
Green technology, also known as sustainable technology, considers both the long- and short-term environmental effects of a product. By definition, green products are environmentally friendly. A green product or technology incorporates energy efficiency, recycling, health and safety issues, renewable resources, and other factors. On carbon dioxide emissions, green technological innovation has a direct and scale effect. One is that green technological innovation can successfully reduce carbon emissions through enhancing energy consumption efficiency, i.e., green technological innovation's direct effect on carbon emissions. The other is that green technology innovation encourages the expansion of economic scale and output, which necessitates increased energy consumption and, as a result, indirectly raises carbon emissions, a phenomenon known as the scale effect of green technology innovation on carbon emissions.
