Emissions

Emissions refer to the release of substances into the environment.

Emissions refer to the release of substances, energy, or radiation from a source into the environment, especially into the atmosphere. This term encompasses solid, liquid, and gaseous substances, as well as sound, vibrations, light, heat, and radiation. Emissions can be of natural origin, such as from volcanic activities, wildfires, or biological processes, but they can also be anthropogenic, meaning they are caused by human activities such as industry, transportation, and agriculture.

The most significant types of emissions include air pollutants and greenhouse gases. Air pollutants such as fine dust and nitrogen oxides mainly arise from the combustion of fossil fuels. Greenhouse gases, including carbon dioxide (CO_) and methane (CH_), play a critical role in climate change, as they enhance the natural greenhouse effect. The sources of these emissions vary and include both natural processes and human activities in areas such as energy production and agriculture.

The impacts of emissions are far-reaching and include climate change, health issues from air pollutants, and damage to ecosystems. In Germany and the EU, emissions are regulated by various legal regulations as well as measures for emission reduction such as the expansion of renewable energy. Recent developments show that the reduction of greenhouse gas emissions is a central concern of European climate policy to achieve the goals of international agreements and minimize future environmental burdens.
