"Baseline scenarios without any new climate policies, and without the implementation of current pledges, lead to a median global warming of 3.3C-5.5C by 2100" says leaked draft of @IPCC_CH WG3 report summary out on Monday.
And, the longer we wait the harder it gets. UpSum - we need to go further, faster, NOW. And that's just looking at the 1.5C-2C range. No more than 1.5 is harder still.
Interesting focus on UpFront Carbon, natural materials and urban design, presumably to temper the business as usual climate destructive building scenario. Looking forward to seeing the detail....And possibly UK specific pathways.? @ArchitectsCAN
And, financial flows are not getting the job done and bigger public finance investment is required. Mismatch between capital, and investment needs is highlighted. This is for the world but it sounds a lot like UK. @GFI_green

The @IPCC_CH#WG3 report buildings chapter is punchy. Calls for downsizing taxes because growth in residential floorspace per head is the biggest driver of CO2 in buildings 1990-2019 (56%). @UKGBC@ArchitectsCAN
Report rubbishes the idea that hydrogen will heat buildings - cost 'much higher' than cost of heat from heat pumps.
And focuses on reducing #UpFrontCarbon by building less floorspace, more efficiently, and replacing steel, brick and concrete with timber (and using less fossil fuel to make materials). And concludes there are sufficient forests and fields in Europe to provide timber & insulation
