Greenhouse gas emissions

Definition

Greenhouse gas emissions refer to the release of gases into the Earth's atmosphere that trap heat, contributing to the greenhouse effect and global warming. These emissions primarily come from human activities such as burning fossil fuels, deforestation, and industrial processes, leading to increased concentrations of gases like carbon dioxide, methane, and nitrous oxide. Reducing these emissions is critical for mitigating climate change and optimizing energy systems.
