carbon intensity

Carbon intensity refers to the amount of carbon dioxide (CO₂) emissions produced per unit of energy or economic activity. It measures how "carbon-efficient" an energy source or process is. For example, electricity generated from coal typically has high carbon intensity because it releases a lot of CO₂, while renewable sources like wind or solar have very low or zero carbon intensity since they don’t emit CO₂ during operation. Reducing carbon intensity helps lower overall greenhouse gas emissions, which is important for combating climate change. It’s a useful way to compare the environmental impact of different energy sources and activities.
