Sustainability and waste management on board are key issues that need to be addressed by the maritime sector also in terms of greenhouse gas emissions (GHG). With the aim of evaluating waste management alternatives in a circular economy perspective, the study examines a combined system for the optimisation of ship waste management and assesses its possible use for energy purposes. Different systems are analysed in relation to their GHG emission reduction potential regardless of routes and ports of destination. A SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis was carried out on waste management alternatives in order to preliminary identify their potential in terms of GHG emissions reduction, cost, environmental sustainability, methodological coherence, feasibility and replicability. Following this analysis, two case studies of particular interest were identified: (1) the thermo-chemical treatment of waste oils and sludge to obtain fuel oils; (2) the installation of a waste-to-energy plant and subsequent energy recovery on board. UNFCCC (United Nations Framework Convention on Climate Change) methodologies were applied to these two case studies to calculate GHG emission reduction resulting from their implementation. The obtained results are presented with the aim of supporting sustainable waste management strategies on board in a circular carbon economy perspective.

This paper investigates costs and benefits associated with low-carbon economic development pathways realization to the mid XXI century. 30 scenarios covering practically all “visions of the future” were developed by several research groups based on scenario assumptions agreed upon in advance. It is shown that with a very high probability Russian energy-related GHG emissions will reach the peak before 2050, which will be at least 11% below the 1990 emission level. The height of the peak depends on portfolio of GHG emissions mitigation measures. Efforts to keep 2050 GHG emissions 25-30% below the 1990 level bring no GDP losses. GDP impact of deep GHG emission reduction - by 50% of the 1990 level - varies from plus 4% to minus 9%. Finally, very deep GHG emission reduction - by 80% - may bring GDP losses of over 10%.

Potential Threat

As awareness regarding the potential threat of climate change has grown in the US, many local governments and businesses are being asked to consider the climate implications of their actions. In addition, many leaders, including solid waste managers, who are not yet pressured from the outside, consider it prudent to account for their greenhouse gas (GHG) emissions and consider it a proactive measure to assess climate risks and opportunities and to show commitment to progress. Sources of GHG emissions in the solid waste management process include: waste transport vehicles, composting facilities, processing equipment, landfills, and waste-to-energy facilities. Over the past 25 years, the levels of GHG emissions have been reduced through technological advancements in waste-to-energy, environmental regulations such as the Clean Air Act, landfill gas capture and control, and the promotion of recycling and reuse. There are many opportunities for solid waste managers to further reduce their GHG emissions levels, including promotion of waste-to-energy facilities as part of a low-carbon solid waste management plan. Waste-to-energy may also, in the future, offer potential revenue from the sale of renewable energy credits and carbon credits in emerging emissions trading programs.

GHG reductions are a major focus of the EU policy. Several regulations have been set in order to meet the EU commitments under the Paris Agreement with an overall reduction of 40% from 1990 level. For the transport sector which is responsible for around 20% of the total GHG emissions, the GHG reductions obligations have been translated by i) reinforced GHG reduction thresholds for biofuels into the recast Renewable Energy Directive RED II; ii) an ambitious target of 30% GHG emission reduction target from 2005 level in the Effort Sharing Regulation (ESR) common to “non-ETS sector” (not covered by the Emission Trading System – ETS) as agriculture, building, waste… and transport. Furthermore, other EU regulations directed to Cars, Vans as well as Heavy Duty Vehicles set GHG emission reduction targets for new vehicle up to 2030. Finally, in its communication “A Clean Planet for All” the EU Commission describes A Strategy for 2050 to achieve a carbon neutral economy. This article addresses also the case of the German “GHG quota” which is a national support system for biofuels and as such is parallel to the European obligations stemming from the RED II renewable energy mandates that are to be met by Germany.

Avoided Emissions

More light is being shed continually on the environmental impacts of municipal solid waste due to the increasing amounts of waste generated and the related greenhouse gas emissions. Emissions from MSW account for 20% of Canadian greenhouse gas (GHG) emissions and accordingly, waste legislation in Ontario demands high waste recovery and a moving towards a circular economy. This study evaluates the current municipal solid waste management in the City of Guelph and assesses possible alternative scenarios based on the associated GHG emissions. Waste Reduction Model (WARM) that was developed by the US-EPA has been used to quantify the GHG emissions produced over the entire life cycle of the MSW management scenario. Sensitivity analysis was also conducted to investigate the influence of some scenarios on the overall GHG emissions. It has been found that one ton of landfilled waste generates approximately 0.39 ton of carbon dioxide equivalent (CO2Eq). It was also found that the current solid waste scenario has a saving of 36086 million ton of CO2Eq (MCO2Eq). However, the results showed that the scenario with enhanced waste-to-energy, reduction at source and recycling has resulted in a high avoided emissions (0.74 kg CO2Eq/kg MSW). The anaerobic Digestion scenario caused the lowest avoided emissions of 0.39 kg CO2Eq/kg MSW. The net avoided emissions for reduction at source scenario were found to be the same as that found by the current scenario (0.4 kg CO2Eq/kg MSW). The sensitivity analysis of both reduction at source and recycling rates show a linear inverse proportional relationship with total GHG emissions reduction.

AbstractMany information and communications technology (ICT) services have become commonplace worldwide and are certain to continue to spread faster than before, particularly along with the commercialization of 5G and movement restrictions in response to the COVID-19 Pandemic. Although there is a concern that ICT equipment usage may increase power consumption and emit greenhouse gas (GHG) emissions, ICT has also been contributing to reducing GHG emissions through improved productivity and reduced mobility. This research targeted the main ICT services used in Japan and adopted a dynamic national computable general equilibrium model to quantitatively analyze future impacts on economic growth and GHG emission reduction until 2030 by using these ICTs, while considering both the increase in power consumption of ICT itself and the reduction in environmental load in other sectors. The results showed that the spread of ICT services, especially some artificial intelligence-based services, can improve productivity in most sectors through labor-saving and contribute to improving overall gross domestic product (GDP). Additionally, increased efficiency of logistics and manufacturing can greatly reduce the input of oil and coal products and so greatly contribute to GHG emission reduction. In 2030, compared with the baseline scenario in which all technology levels are fixed at current levels, at least 1% additional GDP growth and 4% GHG emission reduction can be expected by the targeted introduction of ICT in the ICT accelerated scenario in which the technology level of ICT accelerates. This also means ICT can potentially decouple the economy from the environment.

The International Maritime Organization adopted a strategy to reduce the total annual GHG emissions from international shipping by at least 50% by 2050, compared to 2008 levels. The European Union proposed an even farther reaching transformation: the European Commission adopted a set of proposals to make the EU’s transport policies fit for reducing net greenhouse gas emissions by at least 55% by 2030, compared to 1990 levels. Therefore, all industrial actions in line and consistent with these strategies are essential. One of such activities may be a gradual transition from the most common independent controls of transport ships’ thrusters, propellers, and rudders to an integrated, power optimized, 3 degrees of freedom joystick control. In this paper, the full mission bridge simulator (FMBS) research on potential energy savings and, consequently, a GHG emission reduction, while steering a RoPax twin-screw ferry equipped with bow thrusters by a joystick control, is presented. The task of navigators engaged in the research was to steer the vessel either via classic engine, rudder, and thruster levers or via a joystick while (1) following the predefined straight track, (2) rotating at the turning area, and (3), finally, crabbing (moving sideways) until stopping at the quay fenders. The conclusions are that energy savings of approximately 10% can be expected for berthing manoeuvres controlled by a joystick, compared to independent actuators’ controls. These conclusions have been drawn from a statistical analysis of the ship’s energy consumption during typical manoeuvring phases of 18 berthing operations performed in FMBS.

It has been agreed that forestry is a key sector in the effort to tackle global warming. The government has demonstrated actual commitment to reduce GHG emissions by 26% with their own budget and by 41% with international financing. This commitment is set forth in Presidential Decree No. 61 Year 2011. This regulation indicates that one of the largest emitters is the forestry sector. The government has already allocated Specific Allocation Fund (DAK) Forestry in the State Budget annually to support forest rehabilitation. Despite the relatively small amount, the fund allocation is increasing significantly each year. The question is how the allocation for DAK Forestry can be synchronized with the GHG emission reduction target set forth in Presidential Decree No. 61 of 2011. For that reason, this study has been conducted in order to analyze the conformity of DAK Forestry funding with the emission reduction targets set forth in Presidential Decree No. 61 of 2011. By using qualitative descriptive statistical approach, it is known that the use of DAK Forestry fund as from 2010 to 2014 has had a significant alignment in support of GHG emission reduction target set forth in Presidential Decree No. 61 of 2011.

Purpose This paper aims to investigate potential impact of internal carbon pricing in emission reduction in Higher education institutions (HEIs). Over the past century, human activities have increased greenhouse gas (GHG) emissions in the atmosphere. If GHG emissions continue their upward trend, this will disturb the natural balance and trigger abrupt changes in all components of the climate system. Limiting climate change would require a substantial and sustained reduction in GHG emissions from all sectors. HEIs, as major emitters, indeed need to respond to the demand to become more sustainable by making practical changes to the way their institution is run. Design/methodology/approach Using emission data associated with campus waste, this study describes how HEIs can take the lead on emission reduction through the implementation of carbon pricing. Findings Specifically, this study estimates the cost of emissions from campus waste to illustrate the primary benefits of internal carbon pricing for scaling up campus carbon neutrality initiatives and describes practical implications for enhancing sustainable waste management in a university setting. This study will contribute to identifying the potential for emissions reduction through waste management using a carbon pricing mechanism in university settings. Originality/value While carbon pricing has long been regarded as an alternative approach to tackling carbon pollution, it has not been thoroughly explored with regard to waste management.

Calcination Process

Sheet Glass Industry is one industry that uses 75 % natural gas energy and 25 % electricity. Using the Intergovernmental Panel on Climate Change, IPCC-2006 emission calculation method, the average greenhouses gas (GHG) emissions obtained from the calcination process obtained 112 211 t CO2 yr–1 per plant and an average emission factor (EFkl) of 0.18 CO2 t–1 yr–1 of pull. With the technology of converting heat into electrical energy, residual combustion as flue gases has the potential to be used to produce electrical energy. Referring to the analysis and calculation; one of factories has potential to generate 0.8 MW to 3 MW electric energy. It’s efficiency of 10 % to 40 % so that it can be calculated as a component of GHG emission reductions whose value is 4.6 t CO2 yr–1 to 18.7 t CO2 yr–1 per plant. With this reduction, each of the GHG emission and emission factors per plant dropped to 93 442 t CO2 yr–1 and 0.16 CO2 t-pull–1.
