CO2utandning

CO2utandning, also known as carbon dioxide emissions, refers to the release of carbon dioxide (CO2) into the atmosphere, primarily as a result of human activities. This process is a significant contributor to the greenhouse effect and global warming. The primary sources of CO2 emissions include the burning of fossil fuels such as coal, oil, and natural gas for electricity generation, transportation, and industrial processes. Deforestation also contributes to CO2 emissions by reducing the number of trees that can absorb CO2 through photosynthesis. Other sources include agriculture, land use changes, and waste management. The measurement of CO2 emissions is crucial for understanding and mitigating climate change. It is typically expressed in units of carbon dioxide equivalent (CO2e), which accounts for the global warming potential of different greenhouse gases. Reducing CO2 emissions is essential for achieving the goals set by the Paris Agreement, which aims to limit global temperature rise to well below 2 degrees Celsius above pre-industrial levels. Strategies to reduce CO2 emissions include transitioning to renewable energy sources, improving energy efficiency, promoting sustainable land use practices, and enhancing carbon capture and storage technologies. International cooperation and policy interventions are also vital for effectively addressing CO2 emissions and combating climate change.
