The total amount of greenhouse gases, especially carbon dioxide, released into the atmosphere by human activities (like driving, manufacturing, or using electricity).
Carbon footprint – 碳足迹
The release of gases (like CO₂ or methane) into the air, often from cars, factories, or power plants.
Emissions – 排放
Energy that comes from sources that do not run out and do not harm the environment, such as solar, wind, hydro, or geothermal power.
Sustainable energy – 可持续能源
The layer of gases surrounding Earth, which includes the air we breathe and plays a key role in regulating climate and temperature.
Atmosphere – 大气层
A unit of measurement (1 ton = 1,000 kilograms) used to describe the amount of carbon dioxide or other emissions.
Ton – 吨
Materials used in buildings to keep heat in during the winter and out during the summer, reducing the need for energy and cutting emissions.
Insulation – 保温
A powerful greenhouse gas that is produced by natural sources (like wetlands) and human activities (like livestock farming and fossil fuel use).
Methane – 甲烷
Gases like carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) that trap heat in the Earth’s atmosphere, causing the planet to warm up.
Greenhouse gases – 温室气体
