Table 1.

Best and worse case scenarios for 2030

Is this the worst case?	Is this the best case?
UK dependent on fossil fuel from unstable sources. Unreliable supply means electricity rationing has reduced productivity by a third.	Renewable energies provide 40% of UK heat and power. Many domestic customers are now net suppliers to the grid through wind and solar schemes.
National average SAP remains below 60. Tenant and owner relationships break down due to energy costs.	Fuel poverty eliminated in 2013. Homes refurbished to meet national average SAP of 100 by 2015
Water rationing throughout the UK and water piped from north to south.	Reduction in water use. Increase in recycling and biological sewage treatment helps maintain supplies and keep costs low.
Road and runway building still underway as gridlock increases. Air pollution contributing to one million premature deaths per year.	Walking, cycling and public transport now the most popular choice for journeys under 10 km. Air traffic taxed in line with other modes of transport.
Record numbers of directors in prison for corporate manslaughter. UK construction industry shrunk to half of 1990 levels due to overseas competition offering more predictable services.	Modern methods of construction have eradicated accidents and maximised UK construction productivity, predictability, profitability and energy efficiency.
Adversarial contracts lead to sub-optimal design to the detriment of clients, users, and communities.	Integrated teams on non-value-linked fees work with clients, users and communities to create best value products and services.
Landfill capacity reached in 2017. Waste disposal is single biggest construction cost.	Construction became a zero waste industry in 2023
