Also addition of zeolite to the concrete improves the mechanical strength of the concrete. 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. Concrete is used for wide range of applications like construct buildings, bridges, roads, runways, sidewalks, and dams. Concrete is the second most widely used material on earth after the water. A single cement industry accounts for around 5 percent of global carbon dioxide emissions. One such industry which emits carbon dioxide is cement industry. There are many industries emitting the flue gases which include steam, sulphur dioxide, nitrogen dioxide, carbon dioxide. “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. 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. We also compare the approximate present value of benefits estimated using the SCC to the exact value of compensating variation in the initial period for a wide range of hypothetical emission reduction policies. In our Monte Carlo simulation, the certainty-equivalent SCC is more than four times larger than the expected value of the SCC, and we show that this result depends crucially on how the uncertain preference parameters are handled. We find that, due to the combined effects of uncertainty and risk aversion, the certainty-equivalent SCC can be substantially larger than the expected value of the SCC. We use the model to conduct sensitivity analyses over some of the key input parameters, and we compare estimates of the SCC under certainty and uncertainty in a Monte Carlo analysis. Our goal is to provide a tool to help analysts and decision-makers quickly explore the implications of various modeling assumptions for the SCC. The model includes the essential ingredients for calculating the SCC at the global scale and is designed to be transparent and easy to use and modify. This paper develops a rapid assessment model for the SCC. The "social cost of carbon" (SCC) is the present value of the stream of future damages from one additional unit of carbon emissions in a particular year. Recognition of the full SCM, which has typically been undervalued, may help catalyze actions to reduce emissions and thereby provide a broad set of societal benefits. The results indicate that efforts to reduce methane emissions via policies spanning a wide range of technical, regulatory and behavioural options provide benefits at little or negative net cost. ![]() Examining recent trends in methane and carbon dioxide, we find that increases in methane emissions may have offset much of the societal benefits from a slowdown in the growth rate of carbon dioxide emissions. ![]() In the agricultural sector, changes in livestock management practices, promoting healthy diets including reduced beef and dairy consumption, and reductions in food waste have been promoted as ways to mitigate emissions, and these are shown here to indeed have the potential to provide large societal benefits (∼$50–150 billion per year). Within the energy sector, renewables compare far better against use of natural gas in electricity generation when incorporating these social costs for methane. Our results suggest that ∼110 of 140 Mt of identified methane abatement via scaling up existing technology and policy options provide societal benefits that outweigh implementation costs. These values are ∼100 and 50 times greater than corresponding social costs for carbon dioxide. ∼$2400 per ton and ∼$3600 per ton with 5% and 3% discount rates respectively. Calculating the SCM using consistent temporal treatment of physical and economic processes and incorporating climate- and air quality-related impacts, we find large SCM values, e.g. Use of a broad measure of social welfare is also an attractive alternative or supplement to emission metrics focused on a temperature target in a given year as it incentivizes action to provide benefits over a broader range of impacts and timescales. Quantifying these damages to the planetary commons by calculating the social cost of methane (SCM) facilitates more comprehensive cost-benefit analyses of methane emissions control measures and is the first step to potentially incorporating them into the marketplace. Methane emissions contribute to global warming, damage public health and reduce the yield of agricultural and forest ecosystems.
