Sustainability has turned into a key focus within the construction industry as a result of governmental pressures.

In the last handful of years, the construction industry and concrete production in particular has seen significant change. Which has been especially the situation regarding sustainability. Governments across the world are enacting stringent legislation to apply sustainable methods in construction ventures. There is a more powerful focus on green building efforts like reaching net zero carbon concrete by 2050 and a greater interest in sustainable building materials. The interest in concrete is anticipated to increase due to population growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr may likely attest. Numerous countries now enforce building codes that need a certain portion of renewable materials to be used in construction such as for instance timber from sustainably manged woodlands. Additionally, building codes have included energy saving systems and technologies such as green roofs, solar power panels and LED lights. Also, the emergence of new construction technologies has enabled the industry to explore innovative solutions to enhance sustainability. As an example, to lessen energy consumption construction businesses are building building with large windows and using energy conserving heating, air flow, and air conditioning.

Old-fashioned energy intensive materials like concrete and steel are increasingly being gradually replaced by more environmentally friendly options such as bamboo, recycled materials, and manufactured wood. The primary sustainability enhancement into the construction sector though since the 1950s is the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a percentage of the concrete with SCMs can significantly reduce CO2 emissions and energy consumption during production. Also, the incorporation of other sustainable materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction into the past few years. The usage of such materials have not only lowered the interest in raw materials and resources but has recycled waste from landfill sites.

Conventional concrete manufacturing utilises large stocks of raw materials such as for instance limestone and cement, which are energy-intensive to draw out and produce. Nevertheless, industry experts and business leaders such as Naser Bustami would probably aim down that novel binders such as geopolymers and calcium sulfoaluminate cements are effective enviromentally friendly options to old-fashioned Portland cement. Geopolymers are manufactured by triggering industrial by products such as fly ash with alkalis resulting in concrete with comparable as well as superior performance to mainstream mixes. CSA cements, on the other hand, need reduced temperature processing and emit fewer greenhouse gases during manufacturing. Therefore, the use of those alternate binders holds great possibility cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are increasingly being built. These innovative techniques make an effort to catch carbon dioxide (CO2) emissions from concrete plants and use the captured CO2 in the manufacturing of synthetic limestone. This technologies may potentially turn cement as a carbon-neutral as well as carbon-negative material by sequestering CO2 into concrete.
