A patchwork of solutions
Shell continues to develop its scenarios work to better understand the practical challenges ahead.
"We find the goal of a better life with a healthy planet to be an inspiring ambition," Ben van Beurden, CEO of Royal Dutch Shell, says in the report's preface. "Navigating the necessary transitions will require extraordinary and unprecedented co-ordination, collaboration and leadership across all sectors of society."
As the world's energy system responds to a growing population expecting better living standards, it is likely to double its size this century. Such enlargement brings with it the potential growth of atmospheric CO2 and other greenhouse gases, unless a collective effort is made to reduce global emissions so that there are no net additions.
The supplement presents a range of approaches to decarbonise the global economy in a way that might address both the challenge of climate change and the need for broader economic growth. It finds that no single solution will catapult the world into a net-zero economy.
Instead it is likely to come from a patchwork of approaches. Different degrees of decarbonisation and energy efficiency will be achieved at different paces, in different regions, and in different sectors of the economy.
