#9 A Closer Look Under the Hood of Our Energy Sectors
The energy sectors of the world make our everyday lives possible. They are the main contributors to global CO₂ emissions, and as such they hold the key to our salvation.
Energy Sector
Industry
Almost a quarter of global greenhouse gas emissions come from the industrial sector. Steel and cement are the two highest-emitting industry subsectors, followed by the chemical subsector.
Transport is the largest oil-consuming sector today, it accounts for a fifth of global energy demand and the sector is responsible for a quarter of energy-related CO₂ emissions.
Heat is the largest energy end-use sector, accounting for around half of global energy consumption. Heat production is heavily based on fossil fuels, with only 10 per cent produced from renewable sources.
