CO2päästöä
CO2päästöä, or carbon dioxide emissions, refer to the release of CO₂ into the atmosphere from various human activities. The primary sources include combustion of fossil fuels for electricity generation, heating, and transportation, industrial processes such as cement and steel production, and certain agricultural practices. The concentration of CO₂ in the atmosphere has risen from about 280 parts per million before the Industrial Revolution to over 420 parts per million today, contributing to global warming and climate change. Measurements of CO₂ emissions are typically reported in metric tons per year and are used by governments and international organizations to track progress toward emission reduction targets. Many countries now track emissions through national inventories that follow the Intergovernmental Panel on Climate Change (IPCC) guidelines, ensuring consistency and comparability. Mitigation strategies involve shifting to renewable energy sources like wind, solar, and hydroelectric power, improving energy efficiency in buildings and industry, adopting electric vehicles, and implementing carbon capture and storage technologies where feasible. Global agreements such as the Paris Agreement aim to limit temperature rise by reducing CO₂ emissions, with countries submitting nationally determined contributions that outline specific emission trajectories. Continued monitoring and policy changes are essential to achieving a balance between economic development and environmental sustainability.
