“…The LEAP model can be used as a tool to analyze various scenarios for energy policy and GHG mitigation assessments. For example, Nojedehi, Heidari [ 27 ] employed LEAP to analyze power production from landfill gas and its environmental impacts in Tehran in 2035. Uhorakeye and Möller [ 28 ] assessed electricity demand towards 2050 in Rwanda using LEAP where power generation was deficient.…”

The sources of greenhouse gas (GHG) emissions in Thailand come from the energy sector, including power generation, transport, industries, buildings, and households. In 2016, the energy sector contributed 77 percent of total GHG emissions. Thailand's energy policies are the essential instrument to deal with GHG emission reduction under the United Nations Framework Convention on Climate Change (UNFCCC). The renewable energy (RE) plans aim at increasing the share of RE in final energy consumption while the energy efficiency (EE) plans aim at improving energy efficiency as well as reducing fossil-fuel consumption. GHG emission mitigation will result in several co-benefits such as increasing energy security and decreasing local air pollutants. Therefore, this study analyzes potentials of GHG emission reduction during 2015–2050 from utilization of renewable energy and increasing energy efficiency using the Long-range Energy Alternative Planning system (LEAP) model. Results include potentials of domestic RE and EE measures to achieve Thailand's nationally determined contribution (NDC). Moreover, it was found that to meet Thailand's first NDC of 20 percent GHG emission reduction target in 2030, targets in the RE plan and the EE plan must be achieved by at least 50 percent and 75 percent, respectively, or targets in the RE plan and the EE plan must be achieved by at least 75 percent and 50 percent. In addition, the extended NDC scenario in 2050 is analyzed in the long-term perspective of Thailand showing 30.4 percent reduction when compared to the BAU. The policy implication includes promotion of energy efficiency, acceleration of the deployment of renewable energy and advanced technologies such as CCS, completion of transmission network for renewable electricity, zoning of biomass sources, and public awareness in climate changes.

“…Park et al [36] used LEAP to simulate the annual electricity demand and supply system of Japan from 2011 to 2030 as an alternative electricity scenario to meet the goals of nuclear phase-out and greenhouse gas emission reduction. Different authors have used LEAP as a long-term scenario analysis and management tool-although their scope, context, duration, sector and methodology differ-for different countries (e.g., for Taiwan [37], Korea [38], Pakistan [39], Iran [40], Ghana [41] and Lebanon [42]). A schematic representation of the LEAP model framework implemented in this work is shown in Figure 2.…”

Cooking energy has an important role in energy demand of Nepal. Over the last decade, import of Liquefied Petroleum Gas (LPG) has increased by 3.3 times as an alternate cooking fuel to kerosene and firewood. The growing subsidy burden to endorse modern fuel switching from traditional energy sources and high import of LPG are challenges for sustainability and energy security. This paper analyzes the future residential cooking energy demand and its environmental and economic impacts from 2015 to 2035 using a Long-range Energy Alternative Planning System (LEAP) tool. In 2035, the LPG demand for cooking is projected to be 26.5 million GJ, 16.3 million GJ, 45.2 million GJ and 58.2 million GJ for business as usual (BAU), low growth rate (LGR), medium growth rate (MGR) and high growth rate (HGR) scenarios, respectively. To substitute LPG with electricity in the cooking sector by 2035, an additional 1207 MW, 734 MW, 2055 MW and 2626 MW hydropower installation is required for BAU, LGR, MGR and HGR scenarios, respectively. In the MGR scenario, substituting LPG with electricity could save from $21.8 million (2016) to $70.8 million (2035) each year, which could be used to develop large-scale hydropower projects in the long term.

“…Palestinian waste was also reported to have a DOC content of 0.25 g C/g MSW (Abualqumboz et al, 2016). More recent articles from Iran (south-central Asia) (Asadi et al, 2014; Nojedehi et al, 2016) and Egypt (Northern Africa) (Abdelmonem et al, 2014) reported more typical DOC values of 0.151, 0.141, and 0.12 C/g MSW, respectively. Thus, the range for Western Asia and the Middle East is skewed high, perhaps unrealistically.…”

“…Importantly, too, a managed SWDS scenario (i.e., MCF = 1.0) has been applied at least once in every World-Bank-defined region. Five of the reported values were a weighted average of several sites (Abushammala et al, 2011; Cabrera, 2013; Nojedehi et al, 2016; Pipatti and Wihersaari, 1998; Weitz et al, 2008).…”

The Intergovernmental Panel on Climate Change (IPCC) protocol for predicting national methane emission inventories from landfills was published 22 years ago in the 1996 Revised Guidelines. There currently exists a broad dataset to review landfill parameters and reported values and their appropriateness in use and application in a range of site-specific, regional, and national estimates. Degradable organic carbon (DOC) content was found to range from 0.0105 to 0.65 g C/g waste, with an average of 0.166 g C/g waste. The fraction of DOC that would anaerobically degrade (DOC ) was reported to range from 50-83%, whereas higher and lower values have been experimentally determined for a variety of waste components, such as wood (0-50%) and food waste (50-75%). Where field validation occurred for the methane correction factor, values were substantially lower than defaults. The fraction of methane in anaerobic landfill gas ( F) default of 50% is almost universally applied and is appropriate for cellulosic wastes. The methane generation rate constant ( k) varied widely from 0.01 to 0.51 y, representing half-lives from 1 to 69 years. Methane oxidation (OX) default values of 0 and 10% may be valid, but values greater than 30% have been reported for porous covers at managed sites. The IPCC protocol is a practical tool with uncertainties and limitations that must be addressed when used for purposes other than developing inventories.
