Kasvihuonepäästö, also known as greenhouse gas emissions, refers to the total amount of greenhouse gases, including carbon dioxide, methane, nitrous oxide, and fluorinated gases, that are released into the atmosphere as a result of human activities. These gases trap heat in the Earth's atmosphere, leading to the greenhouse effect and contributing to global warming and climate change. The primary sources of greenhouse gas emissions include the burning of fossil fuels for energy, deforestation, industrial processes, and agricultural activities. The most significant greenhouse gas is carbon dioxide (CO2), which is released primarily through the combustion of fossil fuels such as coal, oil, and natural gas. Methane (CH4) is another potent greenhouse gas, emitted from sources like livestock farming, rice cultivation, and the extraction and transport of fossil fuels. Nitrous oxide (N2O) is released from agricultural and industrial activities, as well as from the burning of fossil fuels and solid waste. Fluorinated gases, which include hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride, are synthetic gases used in various industrial applications and are highly potent greenhouse gases. The Intergovernmental Panel on Climate Change (IPCC) has established that reducing greenhouse gas emissions is crucial for mitigating the impacts of climate change. This can be achieved through a combination of strategies, including transitioning to renewable energy sources, improving energy efficiency, promoting sustainable agriculture, and protecting and restoring forests. International agreements, such as the Paris Agreement, aim to limit global warming to well below 2 degrees Celsius above pre-industrial levels and pursue efforts to limit the increase to 1.5 degrees Celsius. Monitoring and reporting greenhouse gas emissions are essential for tracking progress towards these goals and for informing policy decisions.
