As that may take time, appropriate investment over the next decade will be critical to getting cement emissions on track with the Net Zero Scenario. "However, carrying it out on a technical scale would take many years and thus would not provide a short- or medium-term remedy for CO2 emissions.". Conversely, the clinker-to-cement ratio falls 1.0% per year to a global average of 0.65 by 2030 in the Net Zero Scenario, owing to greater use of blended cements and clinker substitutes. The cement industry is the third-biggest producer of carbon dioxide emissions globally, with the estimated 3.5bn tonnes of cement made annually accounting for 8 per . The latter is made by the calcination of lime, clay, and some other components, and forms stable calcium silicate hydrates during hardening, which are responsible for the properties of concrete. In 2021, U.S. energy-related carbon dioxide (CO 2) emissions increased by 296 million metric tons (MMmt), or 6%, compared with 2020 levels.This increase followed a rise in economic activity and energy consumption once the initial economic impacts of the COVID-19 pandemic began to subside. However, changes in land use can be important: estimates indicate that net global greenhouse gas emissions from agriculture, forestry, and other land use were over 8 billion metric tons of CO 2 equivalent, [2] or about 24% of total global greenhouse gas emissions. That's because the concrete industry is responsible for about 8% of carbon dioxide emissions worldwide. ; CO2 emissions per capita in India are equivalent to 1.91 tons per person (based on a population of 1,324,517,249 in 2016), an increase by 0.07 over the figure of 1.85 CO2 . However, cement production is a significant source of greenhouse gas (GHG) emissions - with up to 622 kg of CO2 emitted for each ton of cement produced and the average cement plant producing approximately 3.5 billion tons of cement annually. Substituting high-carbon clinker, which is the main ingredient in Portland cement, with lower-carbon materials will contribute to lowering the CO2 footprint of both cement and concrete, according to the roadmap. As fossil fuel use is projected to decline in the Net Zero Scenario, governments with significant oil and gas infrastructure may also want to study the feasibility of repurposing pipelines for the transport of CO2. The industry has committed to building 10 industrial-scale carbon capture plants by 2030, building on current pilots in North America, India, China and Europe. (2021, November 9).
