The Intergovernmental Panel on climate changes have concluded that- Most paths to halting global temperature increases at 2 degrees and every way to decrease it to 1.5 degrees depend on adopting methods of sucking CO2 from the sky. “CO2 removal has gone from a moral hazard to a moral imperative," says Julio Fried Mann senior research scholar at the Center for Global Energy Policy at Columbia University. There are many industries emitting the flue gases which include steam, sulphur dioxide, nitrogen dioxide, carbon dioxide. One such industry which emits carbon dioxide is cement industry. A single cement industry accounts for around 5 percent of global carbon dioxide emissions. Concrete is the second most widely used material on earth after the water. Concrete is used for wide range of applications like construct buildings, bridges, roads, runways, sidewalks, and dams. So, here’s the concrete with zeolite powder and zeolite sand that captures the carbon dioxide from the ambient air and reduces the atmospheric carbon dioxide making it eco-friendly. Also addition of zeolite to the concrete improves the mechanical strength of the concrete. It is more durable than the ordinary Portland cement. In this review paper, we will discuss the performance and properties of concrete incorporated with zeolite.

Abstract. Permafrost, soil that remains below 0 °C for two or more years, currently stores more than a fourth of global soil carbon. A warming climate makes this carbon increasingly vulnerable to decomposition and release into the atmosphere in the form of greenhouse gases. The resulting climate feedback can be estimated using Earth system models (ESMs), but the high complexity and computational cost of these models make it challenging to use them for estimating uncertainty, exploring novel scenarios, and coupling with other models. We have added a representation of permafrost to the simple, open-source global carbon-climate model Hector, calibrated to be consistent with both historical data and twenty-first century ESM projections of permafrost thaw. We include permafrost as a separate land carbon pool that becomes available for decomposition into both methane and carbon dioxide once thawed; the thaw rate is controlled by region-specific air temperature increases from a pre-industrial baseline. We found that by 2100 thawed permafrost carbon emissions increased Hector's atmospheric carbon dioxide concentration by 10–15 % and the atmospheric methane concentration by 10–20 %, depending on the future scenario. This resulted in around 0.5 °C of additional warming over the next century. The fraction of thawed permafrost carbon available for decomposition was the most significant parameter controlling the end-of-century temperature change and atmospheric carbon dioxide concentration in the model and became increasingly significant over even longer timescales. The addition of permafrost in Hector provides a basis for the exploration of a suite of science questions, as Hector can be cheaply run over a wide range of parameter values to explore uncertainty and easily coupled with integrated assessment models to explore the economic consequences of warming from this feedback.

The European Green Deal and its endeavors will make rapid and far-reaching decisions with major implications for the European cement industry in the short- and longer-term. Accordingly, new measures should be dealt with quickly and effectively to minimize the adverse impact on global warming and global climate change by this sector. The aim of this study is to show and assess the measures to be undertaken to reach carbon neutrality by the Spanish cement industry by 2050. They may be categorized into three broad types based on the main materials: clinker, cement, and concrete. The cement sector must implement breakthrough initiatives, inventions, and technologies regarding the clinker and cement production processes. Furthermore, carbon dioxide uptake by cement-based materials must be considered to achieve the carbon neutrality objective. Accordingly, two methodologies named simplified and advanced, consistent with Guidelines for National Greenhouse Gas Inventories elaborated by the Intergovernmental Panel on Climate Change (IPCC), were selected to model the carbon offsetting by mortars and concretes. Finally, the existing climate change mitigation technologies available in Spain are insufficient to reach the net zero carbon footprint. Therefore, breakthrough technologies such as novel and efficient carbon dioxide capture, utilization, and storage (CCUS) technologies should be implemented by the Spanish cement industry to achieve zero carbon dioxide emissions in 2050.

The circular carbon economy (CCE) is a new concept, developed in detail by Saudi scholars and stakeholders since 2019 and promoted via Saudi Arabia’s Group of Twenty (G20) presidency in 2020. The CCE is conceptualized as an economy in which atmospheric carbon dioxide emissions are minimized and offset by reducing, recycling, reusing, and removing carbon. The concept emphasizes the need to address emissions holistically using all available mitigation options. It also recognizes the economic value of carbon and each country’s specific circumstances.

Reduce Carbon Dioxide

Atmospheric carbon dioxide levels increasing, the climate change has drawn increasing attention. But so far there is no good solution to this problem. This paper presents a simple and feasible way to achieve carbon dioxide liquefaction facility, to reduce carbon dioxide emissions, thereby to improve the climate of the new method. This method is not only technically simple and feasible but also quite inexpensive.
