Preservation Technology Investment

The increase in carbon emissions is considered one of the major causes of global warming and climate change. To reduce the potential environmental and economic threat from such greenhouse gas emissions, governments must formulate policies related to carbon emissions. Most economists favor the carbon tax as an approach to reduce greenhouse gas emissions. This market-based approach is expected to inevitably affect enterprises’ operating activities such as production, inventory, and equipment investment. Therefore, in this study, we investigate a production inventory model for deteriorating items under a carbon tax policy and collaborative preservation technology investment from the perspective of supply chain integration. Our main purpose is to determine the optimal production, delivery, ordering, and investment policies for the buyer and vendor that maximize the joint total profit per unit time in consideration of the carbon tax policy. We present several numerical examples to demonstrate the solution procedures, and we conduct sensitivity analyses of the optimal solutions with respect to major parameters for identifying several managerial implications that provide a useful decision tool for the relevant managers. We hope that the study results assist government organizations in selecting a more appropriate carbon emissions policy for the carbon reduction trend.

Rising greenhouse gas emissions is an important issue of the current time. India’s massive greenhouse gas emissions is ranked third globally. The escalating energy demand in the country has opened the gateway for further increase in emissions. Recent studies suggest strong nexus between energy consumption, economic growth, and carbon emissions. This study has the objective to empirically test the aforementioned interdependencies. The co-integration test and multivariate vector error correction model (VECM) are used for the analysis and the Granger Causality test is used to establish the direction of causality. The time-series data for the period of 1971–2011 is used for the analysis. The results of the study confirm strong co-integration between variables. The causality results show that economic growth exerts a causal influence on carbon emissions, energy consumption exerts a causal influence on economic growth, and carbon emissions exert a causal influence on economic growth. Based on the results, the study suggests a policy that focuses on energy conservation and gradual replacement of fossil fuels with renewable energy sources, which would be beneficial for the environment and the society.

Reductions in greenhouse gas emissions are essential to reducing the rate and scale of anthropogenic climate change to levels that can sustain the planet’s biosphere. A carbon tax is a policy measure that is designed to reduce greenhouse gas emissions by increasing the prices of the highest carbon-polluting goods and services in an economy, thus encouraging substitution towards resultant relatively cheaper and less-polluting goods where possible. When Australia introduced such a tax in 2012, there was a fear that it could threaten the resources boom, considered the engine of Australian economic growth in recent years. By employing a computable general equilibrium model and an environmentally-extended Social Accounting Matrix, this paper demonstrates the effects of a carbon tax on the resources sector. The modelled results show that, in a flexible exchange rate regime, all resources within the sector will be affected negatively but to different degrees. The brown coal sector will be the hardest hit, with a 25.74 per cent decrease in output, 52.94 per cent decrease in employment and 89.37 per cent decrease in profitability. However, other resources in the sector would be only mildly affected. From the point of view of sustainability, the most significant results are that, under the carbon tax, the resources sector contributes considerably to the carbon emission reduction target of Australia. Given that brown coal accounts for only a small portion of the resources sector, it is reasonable to suggest that a carbon tax would not significantly affect the overall performance of the sector.

This study uses a Computable General Equilibrium model to analyze policy scenarios for a carbon tax on greenhouse gas emissions from petroleum fuels and kerosene in Ethiopia. The carbon tax starts at $5 per ton of carbon dioxide in 2018 and rises to $30 per ton in 2030; these rates are translated into taxes on the different energy types covered, depending on their carbon contents. Different scenarios examine the impacts with revenue recycling through a uniform sales tax reduction, reduction of labor income tax, reduction of business income tax, direct transfer back to households, and use by the government to reduce debt. Because petroleum fuels and kerosene are a relatively small part of the Ethiopian economy, the carbon tax has small impacts on overall economic activity and greenhouse gas emissions. In proportional terms, however, the impact on greenhouse gas emissions from these energy sources is notable, depending on the recycling scenario. The assumed carbon tax trajectory also can raise significant revenue—up to $800 million per year by 2030. The impacts on the poor through increased cost of living are not that large, since the share of the poor in total use of the taxed energy types is small. In terms of induced income effects through employment changes, urban households tend to experience more impacts than rural households, but the results also depend on the household skill level and the revenue recycling scenario.

The production of primary aluminum is an energy-intensive industry which produces large amounts of direct and indirect greenhouse gas emissions, especially from electricity consumption. Carbon Emissions Constrained Energy Planning proved to be an efficient tool for reducing energy-related greenhouse gas emissions. This study focuses on energy planning constrained by CO2 emissions and determines the required amount of CO2 emissions from electricity sources in order to meet specified CO2 emission benchmark. The study is demonstrated on and applied to specific aluminum products, aluminum slugs and aluminum evaporator panels. Three different approaches of energy planning are considered: (i) an insight-based, graphical targeting approach, (ii) an algebraic targeting approach of cascade analysis, and (iii) an optimization-based approach, using a transportation model. The results of the three approaches show that approximately 2.15 MWh of fossil energy source should be replaced with a zero-carbon or 2.22 MWh with a low-carbon energy source to satisfy the benchmark of CO2 emissions to produce 1 t of aluminum slug; however, this substitution results in higher costs. This study is the first of its kind demonstrated on and applied to specific aluminum products, and represents a step forward in the development of more sustainable practices in this field.
