Marginal abatement cost curve review
Ibrahim and Kennedy (2016) cite that the MACC was originally applied in specific sectors for several uses that are not restricted to greenhouse gas emissions. It was later that the MACC curves were largely adopted for GHGs emissions in many cities. The concept of MACC was first adopted in the 1970s, to save on the consumption of crude oil, and the 1980s, to save on the consumption of electricity, to adjust with the oil price that shot up in the 1970s. This led to the adoption of the MACCs which were applied to pollutants of air and their effects, as a part of adjusting the systems of the national energy systems and measures of energy conservation, waste management strategies, and others (Ibrahim and Kennedy, 2016).
2.3.4.2 MACC for GHG emissions
Kaiser et al (2009) cite that the MACC, as applied in the domain of climate policy, are designed with a top-down design that create a line which shows the cost-effective pattern line relative to the potential abatement; and bottom-up designs which are created using mitigation measures that are arranged to form steps. Global MACCs are scarce, but they all show that there is an urgent need for mitigation of GHGs, even at a high cost. This is also supported by Faber et al. (2011), where they cite that the natures of the curves suggest a dire need to execute mitigation measures on the GHG emission. MACCs have been important in the climate policy, while dealing in GHGs mitigation in sectors, since they show cost-effectiveness within and without the sectors
