Energy and carbon emission issues from urban metabolism could be undermined towards the urban environmental quality which causes an incremental impact on society. Predicting the slow-onset impacts of environmental degradation requires several urban datasets which has been challenging in the practical analytical process due to data availability and analysis methodology. However, the emergence of open data in the current situation can leverage data users to access, explore the urban situation and apply for multi-scenario analyses. Therefore, this study aims to estimate carbon emissions in suburban areas (Pathumthani province, Thailand) based on open-source-spatial-related data. There are three objectives of this study which include: (1) to collect and construct a spatial database that is necessitate in calculating carbon emission per capita, (2) to quantify spatial carbon emission based on spatial population database by using trend analysis, and (3) to state future challenges of carbon emission in suburban area. Pathum Thani was selected as an extension area of the Bangkok Metropolitan Area with diverse types of land use planning (e.g., residential, industrial, and educational areas). Toward the data gathering process, this study applies secondary data and satellite data incorporated with a parameter of carbon emission for the determination procedure. Spatial trend analysis based on Geographic Information System (GIS) was applied in this study. After the spatial calculation step, the validation process was performed by checking satellite land-use changes based on the analytical time frame. The crucial result showed that the quantity of carbon emission in Pathum Thani province is gradually increasing due to demography changes and the varying land classification. The contribution of this study can be represented as an effort to construct an urban database based on the open-data source, which can draw attention among all stakeholders of urban development to propose the proper urban planning to reach the successfulness of sustainable urban development.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123931514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pakistan also joined the initiative of the World Economic Forum to combat plastic pollution and is on the way to developing its first National Plastic Action Plan (NPAP). One of the easiest ways to fight against the plastic waste issue is recycling already existing plastics. Japan is also working to fight against plastic waste issues. This paper evaluates various aspects of plastic generation and its recycling in Pakistan and compares the results with Japan. The data for this research was collected through various sources such as plastic recyclers, solid waste management experts, existing online databases, consultants, engineers, academic experts, etc., through interviews, questionnaires, and field visits. Through this assessment, the paper identifies the potential challenges and drivers in both countries as some of the drivers in one country may help other countries overcome their challenges, improve plastic waste management/recycling situation, and support a circular economy.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121286290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These disasters lead to substantial loss of life and property and render the affected population homeless many times with little or no resources for survival. The short-term effects of the disasters can last for 1–2 weeks, but the long-term effects can last for months. Water is one of the most important requirements for survival in case of a disaster. For the people to survive, they urgently need food and water. Drinking water and water for general use like washing, cooking and maintaining hygiene are essential for the survival. Under normal circumstances water requirement may be more, but in case of emergency, certain minimum amount of water is required for every individual. Availability of adequate quantity of water is crucial for survival, to maintain adequate hygiene and to avoid ill health. Coagulation is one of the most widely used treatment process for removal of suspended solids. Batch coagulation-based water treatment system like the Oxfam up-flow clarifier has been used by relief organizations on various occasions for emergency treatment. In this study the performance of commercially available chemical coagulants, poly-aluminium chloride (PAC), alum (Aluminum Potassium Sulfate) and natural coagulant, Strychmos Potatorum was studied. These coagulants were studied for their effectiveness in treatment of highly turbid water. The effective optimum dosage of PAC was 10–20 mg/L, alum was 70–80 mg/L and Strychnos Potatorum was 30 mg/Lfor treatment of water under different turbidity ranges under laboratory conditions. PAC was found to be the best coagulant among the three studied. PAC effectively reduced the turbidity of raw water by 99% and was found to be best suited for use for emergency water treatment.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127395354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

De los Reyes","doi":"10.1109/ICUE55325.2022.10113538","DOIUrl":"https://doi.org/10.1109/ICUE55325.2022.10113538","url":null,"abstract":"Over the past few decades, there has been a continuous increase in the public interest for solar energy as an alternative and cleaner source of energy. Therefore, it is not surprising that there is a similar interest in developing accurate models to forecast solar photovoltaic (PV) power production. Such models vary depending on the geographical location of PV sites and the seasons considered. The Philippines has yet to have a solar PV output forecasting model adapted to the country's local conditions. This study aims to evaluate the Seasonal Autoregressive Integrated Moving Average with Exogenous Variables (SARIMAX) forecasting model as a tool for forecasting solar PV generation based on the seasonal characteristics of the country and identify which input parameters are significant for each season. This work used solar PV production data as an endogenous variable. Meanwhile, exogenous variables include in-situ solar irradiance data from solar power plants; and cloud cover, wind speed and direction, ambient temperature, precipitation, and relative humidity, which we extracted from ERA5 Reanalysis data. Datasets were divided based on the seasons as defined by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA), namely, hot dry (HD), rainy (R), and cold dry (CD) seasons. Then, we performed a forecast on each season and one full year to assess the performance of the SARIMAX model. The best model per season was done based on the forecasting accuracy measured using Mean Absolute Error (MAE) and Root Mean Square Error (RMSE). This work analyzed seasonal and year-round SARIMAX models for Baguio City, Philippines. Results show that the cold dry season got the highest accuracy value in terms of 2.26 MAE and 4.06 RMSE. Meanwhile, the rainy season had the lowest accuracy of 12.91 MAE and 16.16 RMSE. We can infer from our findings that seasonal forecasting is better during hot dry and cold dry seasons. We also found that the year-round forecasting model performs better than the rainy season model. From the significant parameters identified in our best models, our analysis showed that wind direction can be removed from all models; irradiation and relative humidity were significant for all seasons.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133407065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the high adoption of solar PV systems can cause negative impacts on distribution networks. The network operators should realize the capacity of distributed energy resources in their systems to maintain power supply and perform active local energy management. This study aims to fill the gap in the detection of invisible solar PV installations. In this paper, proposed PV identification and PV capacity estimation techniques are investigated.

No law enforcement about waste sorting from waste generators affects the contamination of contrary objects in the waste stream. Due to a high proportion of organic waste, mixed waste has high moisture and chloride content, considerable obstacles in the recycling and waste-to-energy businesses. Although refuse-derived fuel (RDF) production to use as a source of fuel for heat and electricity generations is one of the best-available solutions to handle this waste crisis, many factors still disrupt the operation. That is why landfilling is ordinarily used as a waste disposal method. The total RDF usage volume in the cement industry in Thailand is approximately 0.4 million tons per year. The substitution rate is less than 20%. It is quite a few compared with MSW volume and the substitution rate in other cement plants in foreign countries. This study compiled documents and focus group interviews on reviewing the current situation in the MSW supply chain. The results illustrate the problems which need to be solved through the chain. People, as the waste generator, have to sort the waste. The government should impel a policy about waste-to-energy, primarily supporting the private sector to play a more significant role. Moreover, with cost-effectiveness, RDF production and quality improvement technology must be developed to meet cement plants' RDF quality standards. The new RDF products with higher quality, such as low chloride and small size RDF, should be developed to consume RDF in larger quantities. Finally, cement plants as the user need to invest in supporting technology to increase usage volumes, such as chloride by-pass and mechanical feeding systems. In addition, using RDF at other burning points in cement kilns is one of the most exciting issues that cement plants should not be overlooked.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"465 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123377189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using and a narrative literature review and interview of key informants, the case of Catbalogan Sky City Mega Project (CSCMP) was presented. It identifies several issues that must be considered in the designing of the project. At least six operational concerns were identified as well as the environmental issues that it carries. The CSCMP will definitely avoid sea level rise and storm surge but is expected to face water supply production challenges, stronger typhoon winds due to its location, slope instability, and mobility issues and will produce more carbon footprint. On the other hand, the old city is expected to receive more runoff water and excessive soil erosion specifically during development phase increasing flood risk in the old city.

Under rain-fed and irrigated conditions, the CROPWAT8.0 program was used to calculate the WF and CWU values under the SSP245 and SSP585 scenarios based on the CMIP6 model at three time periods: near (2015–2039), mid (2040–2069), and far (2070–2100). The results showed that the total WF values under rain-fed and irrigated conditions in the baseline scenario were 4140.87 m3ton−1 and 3707.10 m3ha−1, respectively. While in the SSP245 and SSP585 scenarios, total CWU values will rise by 1.20 to 6.63% in the near, mid, and far future due to higher temperatures resulting in increased evapotranspiration. Meanwhile, 96.97% of farmers perceived that climate change has been changing, and 81.82% believed climate change had an impact on their farms. The most popular and effective climate change adaptation strategies were increasing irrigation, changing fertilizer application rates, and planting drought-tolerant rice varieties.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132411842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Discount rate is used to determine the present value of future cash flows of the projects. For climate change projects, the lower discount rates are recommended since benefits will be obtained in the long term. In general, private and external costs are used to evaluate the project investment. Combination of both costs is called “social cost”. In this study, only the “social cost of carbon (SCC)”, referring to an estimate of the economic costs of one additional ton of carbon dioxide emitting into the atmosphere, is considered. The objective of this paper is to estimate the SCC in term of carbon tax on the subject of three discount rates with the objective of renewable electricity to achieve carbon neutrality by 2050. Firstly, a 6 percent discount is applied from the base year to 2037. Then, a discount of 3 percent is applied until 2050. The results show that renewable electricity can achieve the carbon neutrality target at SCC of higher than 2.0 USD/t-CO2 and 132.7 USD/t-CO2 for the periods 2020-2037and 2038–2050, respectively.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129471967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
