What country is carbon-free?
Could you please clarify for me which country you are referring to as "carbon-free"? There are several countries that have made significant strides towards reducing their carbon footprint and adopting renewable energy sources, but I'm not aware of any country that has achieved a completely carbon-free status. Some countries, such as Norway, Iceland, and Costa Rica, have high percentages of renewable energy in their energy mix and have ambitious goals for reducing greenhouse gas emissions. However, achieving a truly carbon-free society is a complex and challenging goal that requires significant investments, technological advancements, and changes in consumer behavior.
