Q. Which sector is responsible for the largest greenhouse gas emissions contributing to a 1.5 degrees Celsius temperature rise?
Answer: Energy production
Notes: Energy production, including the burning of fossil fuels for electricity and heat generation, is the sector responsible for the largest greenhouse gas emissions. These emissions primarily consist of carbon dioxide (CO2), which is a significant contributor to global warming. Other sectors like transportation, industrial processes, and agriculture also contribute to greenhouse gas emissions, but their contributions are comparatively smaller. Option A, transportation, includes emissions from vehicles such as cars, trucks, ships, and airplanes. While transportation is a significant source of emissions, it is not the largest contributor to global greenhouse gas emissions. Option B, industrial processes, refers to emissions from manufacturing and production activities. These emissions include gases like methane (CH4) and nitrous oxide (N2O) released during various industrial processes. Although significant, they are not the primary cause of a 1.5 degrees Celsius temperature rise. Option C, agriculture, is responsible for emissions such as methane from livestock and rice production and nitrous oxide from fertilizers. While agriculture is a notable source of greenhouse gas emissions, it is not the sector with the largest contribution to a 1.5 degrees Celsius temperature rise.
