The correct answer is Energy.

Key Points

The energy sector is the largest contributor of greenhouse gases, accounting for two-thirds of the total emissions.
It is followed by the Agriculture sector which accounts for around 20% of the greenhouse gases emission.
Greenhouse gases absorb infrared energy (heat energy) emitted from the earth’s surface and reradiate it back to the earth’s surface.
The greenhouse gases trap heat in the earth’s atmosphere and warm the planet.
The Primary GHGs are:
- Water Vapour.
- Carbon dioxide.
- Methane.
- Nitrous oxide.
