  2. Environmental impact of concrete - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    The environmental impact of concrete, its manufacture, and its applications, are complex, driven in part by direct impacts of construction and infrastructure, as well as by CO 2 emissions; between 4-8% of total global CO 2 emissions come from concrete. [1] Many depend on circumstances.

    Some companies are creating carbon-negative building materials by storing excess carbon dioxide in concrete.

  4. GREET Model - Wikipedia

    en.wikipedia.org/wiki/GREET_Model

    The GREET model is specified in the Inflation Reduction Act of 2022 §45V [2] as the methodology to calculate the life cycle greenhouse gas emissions "through the point of production (well-to-gate)" when determining the level of tax credit for clean Hydrogen production until a successor is approved by the Secretary of the Treasury. The final ...

  5. Health and environmental impact of transport - Wikipedia

    en.wikipedia.org/wiki/Health_and_environmental...

    Environmental regulations in developed countries have reduced the individual vehicle's emission. However, this has been offset by an increase in the number of vehicles, and increased use of each vehicle (an effect known as the Jevons paradox). [3] Some pathways to reduce the carbon emissions of road vehicles have been considerably studied. [5]

    Cemex, North America’s biggest concrete producer, has vowed to slash carbon dioxide emissions by 40% before 2030 and to eliminate them by 2050, ambitious goals reflecting growing pressure on the ...

  7. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Deforestation is a major source of greenhouse gas emissions. A study shows annual carbon emissions (or carbon loss) from tropical deforestation have doubled during the last two decades and continue to increase. (0.97 ±0.16 PgC per year in 2001–2005 to 1.99 ±0.13 PgC per year in 2015–2019) [137] [136]

  8. Carbon negative architecture - Wikipedia

    en.wikipedia.org/wiki/Carbon_negative_architecture

    Concrete, the most used building material globally, accounts for 5% of global annual CO2 emissions due its carbon-extensive production process. [4] In 2023, global carbon emissions were 36.8 billion tons [ 5 ] meaning the concrete construction industry alone emitted 1.84 billion tons of CO2 in 2023, more than most countries besides China, the ...

  9. Embodied energy - Wikipedia

    en.wikipedia.org/wiki/Embodied_energy

    Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy were incorporated or 'embodied' in the product itself. . The concept can be useful in determining the effectiveness of energy-producing or energy saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in ...
