Concrete

I prefer building skyscrapers out of wood to use less concrete. Now that CLT and other wood techniques let us build skyscrapers that are lighter, cheaper, safer, faster, MORE fire safe and ultimately store carbon for centuries – why not use sustainably sourced wood? See Tall Timbers for details and inspiring videos.

Clean energy will also clean up the majority of emissions from concrete. But there are other sources of emissions that even clean energy will not solve – but there are other tricks to reduce the impact. Australia’s “Engineering with Rosie” investigates.
