The Cost

In many industries, multifacility service providers can save time and money and reduce carbon dioxide (CO2) emissions by more efficiently allocating customers to their facilities. However, firms incur a reallocation cost when reassigning a customer to a different facility, something that has not received much attention in the literature. Software packages such as CPLEX can find the optimal solution for this type of problem, but managers rarely use them because they lack the specific knowledge, overestimate the cost, and/or underestimate the benefits. Including the reallocation costs, we modeled several common heuristics in Excel’s Visual Basic and compared the results with the optimal solution found by CPLEX. We collaborated with Van Dorp, a large service provider in the Netherlands, and found that (1) substantial savings can be achieved, (2) reallocation costs play a major role, and (3) the best heuristic achieves near-optimal results. Specifically, reallocating Van Dorp’s 20 “worst allocated” customers realizes a savings of more than 4,000 driving hours and €360,000 in cost and a reduction of 41 tons of CO2 emissions.

Based on the increase of the global interest in climate change, various political and technological efforts are being made in Korea in order to reduce carbon dioxide emissions, considered to be one of the main causes of greenhouse gas effects. Low energy and low carbon technologies with high reusability that enhance the performance of architectural materials have been developed in the architectural construction field [1]. This study has developed an FS insulation panel using recycled resources, and has verified the enhancement of economic efficiency, reduction of carbon dioxide emissions, and enhanced energy performance of the developed insulating panel. The results of the analysis have confirmed a 1.2t reduction of carbon dioxide emissions and a 7.3% increase in energy performance in comparison to standard insulators based on the existing legislative standards. Furthermore, cost effectiveness was also seen as the cost increased by 72% with a 10 year return period.

The Cost

The strategy of low-carbon development of the economy and energy of Russia provides for the introduction of a fee (tax) for carbon dioxide emissions by power plants. This will seriously affect their prospective structure and lead to an increase in electricity prices. The expected neg-ative consequences for national and energy security are great. But serious and multilateral research is needed to properly assess these strategic threats

Reduce Carbon Dioxide

The Paris Agreement, adopted in December of 2015 at the 21st session of the UNFCCC Conference of the Parties and effected from November of 2016, coordinates the efforts of states to reduce greenhouse gas (GHG) emissions, including carbon dioxide. One of its largest emitters to the atmosphere is the metallurgical industry. Among the proposed ways to reduce carbon dioxide emissions is the widespread use of hydrogen in the ferrous metallurgy. An overview of the problems that the ferrous metallurgy will face when replacing carbon-containing fuels with hydrogen is presented. It was noted that the use of hydrogen in the ferrous metallurgy contains such technological risks as high cost in comparison with currently used fuels and reducing agents; explosion hazard and corrosion activity, the need for a radical reconstruction of thermal units when using hydrogen instead of traditional for the ferrous metallurgy natural, coke and blast furnace gases, as well as solid fuels. It is shown that minimizing these risks is not always possible or economically feasible, and the result of using hydrogen in the ferrous metallurgy instead of carbon-containing fuel from the point of view of reducing greenhouse gas emissions may be low with a significant increase of economic and social risks.

Ocean acidification (OA) is caused by increasing atmospheric concentrations of carbon dioxide, which dissolves in seawater to produce carbonic acid. This carbonic acid reduces the availability of dissolved aragonite needed for production of some invertebrate exoskeletons with potentially severe consequences for marine calcifier populations. There is a lack of public information on OA with less than 1% of press coverage on OA compared with climate change; OA is not included in UK GCSE and A Level specifications and textbooks; environmental campaigners are much less active in campaigning about OA compared with climate change. As a result of the lack of public awareness OA is rarely discussed in the UK Parliament. Much more public education about OA is needed so that people can respond to the urgent need for technological and lifestyle changes needed to massively reduce carbon dioxide emissions.
