In a study published in the Journal of Cleaner Production, the authors created a model showing that sequestered CO 2 improved the compressive strength of concrete while reducing CO 2 emissions, thus allowing for a cement loading reduction while also having a "4.6% reduction in the carbon footprint".

According to United Nations Environment Programme (UNEP), "the increased construction activities and urbanization will increase waste which will eventually destroy natural resources and wild life habitats over 70% of land surface from now up to 2032." [14] Moreover, construction uses around half of natural resources that humans consume.
Green building (also known as green construction, sustainable building, or eco-friendly building) refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. [1]
Now, the sector is off track to decarbonize by 2050.
WASHINGTON (Reuters) -The Biden administration on Monday said it will invest $2 billion in 150 federal building projects across 39 states that use materials that minimize carbon emissions, its ...
Carbon negative buildings try to produce their own renewable energy while avoiding the use of fossil fuels during construction and in the materials used. Oftentimes, these materials can sequester carbon within themselves such as with novel building materials such as hempcrete and other bio-based construction materials, which store carbon within plants and turn said plant matter into building ...
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO 2-equivalent) per unit of comparison.
A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...
