7see is a methodology for modelling how an economy will evolve over the next 20 years that serves as a test bed to evaluate policy ideas. The methodology is based on using 20 years of historical data. It allows the creation of evidenced-based scenarios that enable a deeper understanding of how the economy works by considering resources, the built environment, goods, services, international money transactions and people. By combining socio-economic-energy aspects of a country, it is possible to formulate physically consistent scenarios 20 years or more into the future. These scenarios can be visualised using Sankey diagrams, in which line widths are proportional to the volume of flows, a snapshot illustration of the economy in one year. These diagrams capture the breadth of systemic interactions and highlight those of most significance.
 

Schematic of how the built environment for each industry is regarded as using a range inputs in order to produce its own output, services in this case. The capital input needed to maintain and grow the built environment is represented by “FCF”. Dashed lines represent how the 7see model determines the rates of flows.

Many governments around the world are setting out low carbon transition policies and plans with different departments working on their own measures to meet the targets. However, the consequences of one policy may ripple through to others and affect the whole economy. Sometimes the policies overlap or even contradict with each other, resulting in little effect. 7see is a unique, innovative model that brings all the components of an entire economy together to provide evidence-based projection and point out the way forward.

The 7see model has been applied to the economies of the UK, Taiwan and Australia. 7see models are also partially developed for Colombia, Bangladesh, China, and India. The methodology is of benefit to anyone with an interest at an economy-wide macro-level, such as governments, NGOs and major corporations.
