Carbon Footprint Management: A Pathway Toward Smart Emission Abatement

Abstract

There is an increasing concern about controlling and reducing carbon emissions in power systems. In this regard, researchers have focused on managing emissions on the generation side, which is the main source of emissions. Considering emission limits on the generation side results in an increase in locational marginal prices that negatively affects social welfare. However, carbon emissions are a by-product of electricity generation that is used to satisfy the demands on the consumer side. Consequently, demand side emission control may not be achieved if only generation is taken into account. In order to fill this existing gap, in this paper, a demand-side management approach aiming at carbon footprint control is proposed. First, the carbon footprint is allocated among the consumers using an improved proportional sharing theorem method. Each consumer learns about their real-time carbon footprint, excess carbon footprint, and the incurred surcharge tax. Then, demands are adjusted via a proper adjustment procedure. This provides enough information for consumers where demand management may result in carbon footprint and demand reductions as well as the exemption of incurred taxes. Profit analysis for both generation and demand sides is carried out to show the effectiveness of the proposed framework using two illustrative case studies. The results obtained, compared with existing policies such as carbon cap, cap-and-trade, and carbon tax, prove the fairness and the advantages of the proposed model for both the demand and the generation sides.Index Terms-Carbon footprint allocation, carbon abatement, demand side management, power tracing, tax exemption.

Modeling the Supply of Renewable Electricity to Metropolitan Regions in China

“…On the other hand, our scenario analyses result in a large optimization plateau that presents many technologies as valid solutions, thus limiting the risk of costly wrong decisions at the political level. Last but not least, apart from the generation side, exploring carbon reduction potentials from the demand side with options such as carbon cap, cap-and-trade, and carbon tax also play a vital role in achieving a low carbon energy system (see e.g., [47][48][49][50][51]).…”

Efficient Methods of Market Pricing in Power Industry within the Context of System Integration of Renewable Energy Sources

“…Government programs to support renewable energy sources are usually aimed at solving several problems at once [38][39][40][41][42] Many countries use several RES support tools at once. At the same time, it is possible to trace the relationship between the number of tools used to support renewable energy sources and the country's income.…”

Analysis of Carbon Dioxide Emissions From Road Transport Using Taxi Trips

“…Many studies have focused on the mitigation potential of CO2 emissions from transport sector [18,19,20,21,22]. Most of these studies are concerned with traditional decoupling analysis of CO2 emissions from the transport sector.…”
