Energy Transition

The G20 accounts for 82% of global energy-related CO2 emissions – which constitutes the highest share of GHG emissions globally. Energy-related emissions primarily arise from fossil fuel combustion in electricity, heating, industry and transport sub-sectors. In 2018, total energy-related CO2 emissions grew by +1.8% in the G20, in line with a 2% annual growth rate in the total primary energy supply from fossil fuels.

Limiting global warming in line with the Paris Agreement goals will require a radical reduction in energy-related emissions. This calls for what is know as a global energy transition. Such a transition would involve a shift away from fossil fuels and the associated technologies, toward renewable and low carbon energy sources, across the economy.

The power sector accounts for 38% of energy-related emissions in the G20, followed by Industry 24%, Transport 20%, and the Building sector 9%. Due to the relative contribution of the power sector – as well as the interlinkages between the power system and other sectors – decarbonization in this sector is critical to the success of the energy transition.

Key interventions for the energy transition include:
– increasing energy efficiency;
– increasing the share of low-carbon and clean fuels;
– increasing low carbon and renewable power generation.

To arrest global warming at 1.5°, energy-related emissions must be cut by 40% by 2030 and reach net zero by 2060.

Climate Transparency partners are working in G20 countries towards this goal by:
– Providing analysis and recommendations on the energy transition and decarbonization across sectors;
– Involving decision makers and change agents to share learnings, discuss challenges and opportunities;
– Engage in cross-country learnings to increase awareness, knowledge and also capacity.
