The sector that accounts for a significant portion of greenhouse gas emissions globally is the Electric Power sector. This sector is primarily responsible for emissions due to the combustion of fossil fuels for electricity generation, which contributes heavily to carbon dioxide (CO₂) and other greenhouse gases in the atmosphere.

While other sectors such as transportation, industry, and buildings also contribute to emissions, the electric power sector’s reliance on coal, natural gas, and oil makes it one of the largest contributors globally. Efforts to transition to renewable energy sources, such as wind, solar, and hydropower, aim to reduce the carbon footprint of this sector significantly.

Overall, it's essential to focus on improving energy efficiency and increasing the share of renewables in the energy mix to mitigate climate change effectively.
