Ramboll’s Post

Did you know that each year, concrete emits 2.3 billion tonnes of CO2   and iron and steel contribute an additional 2.6 billion tonnes? Together, they’re responsible for 15% of global emissions. Ramboll and the Climate Group have created a survey to investigate the market interest in lower emission alternatives. They are seeking to pinpoint challenges and solutions for increasing the availability and adoption of lower emission concrete and steel within key industries, such as energy, infrastructure, construction, and manufacturing. Follow this link to take part in the survey: https://lnkd.in/d9jDJ_Db The deadline for the survey is 26 July 2024. #BuildingTheTransition

I remember 10+ years ago, Adam R. Christensen, P.E. and I had a coffee chat about “what more can structural engineers do to support sustainability projects” - and while I know neither of us saw this future, here we are as an industry. Some facts about #concrete and it’s associated #embodiedcarbon to start your morning… + concrete is comprised of primary ingredients: sand, gravel, limestone, and water. + concrete is the second-highest consumed product on earth, after water. + in the United States, annual concrete production is roughly equivalent to 2 tons for every American. + every pound of concrete production results in nearly an equivalent amount of carbon dioxide emissions 1 lb concrete = 0.93 lbs CO2. + the global concrete industry accounts for roughly 8% of the worlds’ TOTAL carbon emissions. + The carbon intensity of concrete is the result of two processes in its manufacture: 1. Making cement requires heating limestone to temperatures around 2550°F (1400°C), and while there are electric kilns that could run on renewable energy, this is only 40% of the greenhouse, gas emissions from the production process… 2. the other 60% is literally the carbon dioxide that is cooked out of the limestone as it is heated. So the majority of concrete massive carbon footprint is inherent to the chemistry of the manufacturing process.

Structural engineers "own" a lot of concrete. Listed below are some key facts we need consider when making that slab just a little thicker, or demoing and replacing concrete just to make it pretty. As the primary specifiers, we should think twice about how we can reduce quantity and improve quality of our concrete designs.

The production of both concrete and steel is responsible for around 4.9 billion tonnes of CO2 – that’s 15% of total global emissions 📈🌍 Despite these figures, progress for lower emission alternatives has been slow. But market momentum is building, and a strong demand signal from users could be the catalyst needed to drive a revolution in sustainable construction materials. That’s why we’ve teamed up with Climate Group to create this survey so we can hear from heavy consumers of steel and concrete such as the real estate, infrastructure, and energy sectors. Through the survey, we will discover market interest in lower-emission alternatives, and pinpoint challenges and solutions for increasing the availability and adoption of lower-emission concrete and steel.

Today #ConcreteZero launched a brand new report at #ClimateWeekNYC which shows how the global use of a specific cement alternative will not cut global carbon emissions from concrete. Together with the Institute of Structural Engineers, the Concrete Centre and the 13 experts who authored the report, we're clear that a more innovative approach must be taken.
