A new energy system is emerging. The Paris Agreement has sent a signal around the world: climate change is a serious issue that governments are determined to address. By 2070 there is the potential for a very different energy system to emerge. The Sky Scenario, developed by Shell, outlines what they believe to be a technologically, industrially, and economically possible route forward, consistent with limiting the global average temperature rise to well below 2°C from pre-industrial levels. It reveals the potential for an energy system to emerge that brings modern energy to all in the world, without delivering a climate legacy that society cannot readily adapt to. But while encouraging news, success towards the Paris Agreement aim is not guaranteed. The Sky Scenario relies on a complex combination of mutually reinforcing actions by society, markets and governments. It recognises that the necessary changes will unfold at different paces in different places, and must ultimately transform all sectors of economic activity. The changes are economy-wide, sector-specific, and amount to re-wiring the global economy in just 50 years.
