What is Constuction and Carbon- Negative Concrete?
The construction industry plays a vital role in modern society by providing essential infrastructure for housing, transportation, and economic development. However, it is also a significant contributor to climate change, accounting for nearly 40% of global CO₂ emissions when both building operations and material production are considered (United Nations Environment Programme, 2020). A key source of these emissions is traditional concrete, particularly its main component—Portland cement—which alone contributes around 8% of global CO₂ emissions due to its energy-intensive manufacturing process. To address this issue, carbon-negative concrete has emerged as a sustainable alternative. It absorbs more CO₂ than it emits by using alternative binders, industrial byproducts, and enhancing carbonation processes. This innovation combines durability with carbon sequestration, making it crucial for sustainable construction
What problem will Carbon-Negative Concrete solve?
Carbon-negative concrete addresses several critical environmental problems. Traditional concrete production generates about 8% of global CO₂ emissions due to the high temperatures required to produce cement. Carbon-negative concrete, however, absorbs more CO₂ than it emits, helping to reduce atmospheric carbon levels. This innovation also mitigates climate change by slowing global warming trends linked to greenhouse gas emissions. Furthermore, it lowers resource depletion because some methods use industrial byproducts like fly ash or slag, reducing landfill waste. Additionally, carbon-negative concrete can improve urban air quality and enhance building resilience by incorporating carbon-sequestering minerals that often increase material strength and
