The assessment focuses on electrical power and transportation usage. Questionnaires were distributed to the staffs and students to survey their transportation usage in the year 2014 while for electrical consumption, the study used total energy consumed in the year 2014.Item Open Access The impact of Malaysian economic development on CO2 emission(UiTM Press, 2021) Shaliza Azreen Mohd Zulkifli; Noorfarah Dyana Noorazlan Ong; Rozihanim Sheikh ZainThe manufacturing industry plays an important role as one of the main contributors to Malaysian economic growth. According to the Department of Statistics Malaysia (DOSM), the value of gross output rose 5.7 per cent per annum to RM1,275.8 billion in 2017 as compared to 2015 (RM1,142.0 billion). Even though a greater economic activities leads to greater economic production, unfortunately most forms of economic production generate pollution. Therefore,This study attempts to examine the relationship between economic development and CO2 emission in the context of Malaysia from year 1986 until 2016. The dependent variable used in this study is CO2 emission, while the independent variables are economic growth, population, urbanization and industrialization.Item Open Access The use of constructed wetlands in sequestrating carbon: An overview(Technoscience Publications, 2017) Farah Afiqah Rosli; Khai Ern Lee; Choo Ta Goh; Mazlin Mokhtar; Mohd Talib Latif; Thian Lai Goh; Norbert SimonConstructed wetlands have been proposed to emulate the functions of natural wetlands. However, the use of constructed wetlands in sequestrating carbon is yet to be explored. Therefore, the purpose of this paper is to provide an overview and compare the carbon sequestration potential between natural and constructed wetlands.Item Restricted Vertical variation in mass and CO2 efflux of litter from the ground to the 40m high canopy in a Bornean tropical rainforest(Elsevier, 2021) Ayumi Katayama; Izuki Endo; Naoki Makita; Kazuho Matsumoto; Tomonori Kume; Mizue OhashiLitter usually drops to the ground, but some is retained within the canopy. Mass and CO2 efflux from retained litter may play a significant role in carbon cycling in tropical rainforests where emergent trees with complicated canopy structures are observed. This study aimed to show vertical variation in the mass and CO2 efflux (Rlitter) of the retained litter and examined its contribution to carbon cycling in a Bornean tropical rainforest.Item Restricted Carbon monoxide 'hot-spots' in urban area of Kota Kinabalu City, Sabah(UMS, 2015) Justin Sentian; Ong Pei TzeAir dispersion models have been widely used to address air quality problems at microscale in urban environments, as they are capable of providing valuable information for better and more efficient urban air quality planning. The aim of this paper was to measure the CO concentration near roadways and intersections at three major roads in Kota Kinabalu city centre during morning, afternoon and evening peak hours using CAL3QHC dispersion model and also to identify CO concentration;hot-spots'.Item Restricted Baseline study of methane emission from open digesting tanks of palm oil mill effluent treatment(Elsevier, 2005) Shahrakbah Yacob; Mohd Ali Hassan; Yoshihito Shirai; Minato Wakisaka; Sunderaj SubashAnthropogenic release of greenhouse gases, especially CO2 and CH4 has been recognized as one of the main causes of global warming. Several measures under the Kyoto Protocol 1997 have been drawn up to reduce the greenhouse gases emission. One of the measures is Clean Development Mechanisms (CDM) that was created to enable developed countries to cooperate with developing countries in emission reduction activities. In Malaysia, palm oil industry particularly from palm oil mill effluent (POME) anaerobic treatment has been identified as an important source of CH4. However, there is no study to quantify the actual CH4 emission from the commercial scale wastewater treatment facility. Hence, this paper shall address the CH4 emission from the open digesting tanks in Felda Serting Hilir Palm Oil Mill. CH4 emission pattern was recorded for 52 weeks from 3600 m3 open digesting tanks.Item Restricted The trends and projections of greenhouse gas emission by the livestock sector in Malaysia(Springer, 2022) Muhammad Afq Zubir; Cassendra P. C. Bong; Siti Aktar Ishak; Wai Shin Ho; Haslenda HashimThe greenhouse gas (GHG) emission from the livestock sector is a major concern as GHG can contribute to climate change event such as global warming. The country demand for livestock is rapidly increasing, due to population and economic growth. However, in Malaysia, there is still limited studies on GHG assessment from the livestock sector and its projection based on the self-sufficient level under population growth. In this study, the GHG emissions of different livestock were estimated using the livestock population data published in the year 2010–2019, based on Intergovernmental Panel on Climate Change.Item Restricted The impact of economic growth, energy consumption, trade openness, and financial development on carbon emissions: empirical evidence from Malaysia(Springer, 2021) Zhanar Nurgazina; Arif Ullah; Uzair Ali; Mansoor Ahmed Koondhar; Qian LuGlobally, the rising concentration of anthropogenic greenhouse gases emission in the atmosphere is extremely detrimental to the environment. The high concentration among all greenhouse gases is carbon dioxide emission. Therefore, this study explores the linkages between energy consumption, trade openness, globalization, urbanization, and carbon dioxide emission for Malaysia over the spans from 1978 to 2018.Item Restricted Implementation of the energy efficiency existing ship index and carbon intensity indicator on domestic ship for marine environmental protection(Elsevier, 2023) Lai Fatt Chuah; Kasypi Mokhtar; Siti Marsila Mhd Ruslan; Anuar Abu Bakar; Mohd Azhafiz Abdullah; Nor Hasni Osman; Awais Bokhari; Muhammad Mubashir; Pau Loke ShowThe International Maritime Organization has set a goal to achieve a 50% reduction of total annual greenhouse gas emission related to the international shipping by 2050 compared to the 2008 baseline emissions. Malaysia government has taken an initiative to investigate the assessment (cost-effectiveness) of this International Maritime Organization's short-term measure on Malaysian-registered domestic ships although this measure is only for international merchant ship. To achieve this, this paper collected the ship's data from the shipowners from 25 sample ships.Item Restricted Malaysia's economic growth, consumption of oil, industry and CO2 emissions: evidence from the ARDL model(Springer, 2022) B. Aslam; J. Hu; S. Ali; T. S. AlGarni; M. A. AbdullahThe leading cause of global climate change and warming is greenhouse gas emissions. In developing economic activities, energy plays an important role, and human activities are responsible for climate change, carbon dioxide (CO2) emissions adverse impacts on the environment. This study investigates carbon dioxide emissions from liquid fuel consumption on CO2 emissions rather than total energy consumption.Item Restricted Modeling CO2 emissions in Malaysia: an application of Maki cointegration and wavelet coherence tests(Springer, 2021) Lingyun Zhang; Zecheng Li; Dervis Kirikkaleli; Tomiwa Sunday Adebayo; Ibrahim Adeshola; Gbenga Daniel AkinsolaOne of humanity’s most significant problems in the twenty-first century revolves around how to balance the mitigation of environmental pollution while achieving sustainable economic development. Despite increased awareness and dedication to climate change, the planet is still seeing a drastic decrease in the volume of pollutant emissions. This study explores the long-run and causal impact of economic growth, financial development, urbanization, and gross capital formation on Malaysia’s CO2 emissions based on the STIRPAT framework.Item Restricted How do land use practices affect methane emissions from tropical peat ecosystems?(Elsevier, 2020) Guan Xhuan Wong; Ryuichi Hirata; Takashi Hirano; Frankie Kiew; Edward Baran Aeries; Kevin Kemudang Musin; Joseph Wenceslaus Waili; Kim San Lo; Lulie MellingWetlands in Southeast Asia are thought to be one of the greatest sources of methane (CH4) to the atmosphere. Tropical peatlands are typical in Southeast Asia, and store an enormous amount of soil organic carbon. However, chamber studies of soil CH4 flux have reported that CH4 emissions from tropical peatlands in Southeast Asia are almost negligible. Recently, it was reported that some tree species growing in peat swamp forests emit considerable CH4 from their stems. Thus, ecosystem-scale flux measurement is essential to quantify the CH4 balance of tropical peat ecosystems. In this 3-year study (February 2014 to January 2017), using the eddy covariance technique, we measured the net ecosystem exchange of CH4 (FCH4) above three different tropical peat ecosystems in Sarawak, Malaysia.Item Restricted Carbon dioxide balance of an oil palm plantation established on tropical peat(Elsevier, 2020) Frankie Kiew; Ryuichi Hirata; Takashi Hirano; Wong Guan Xhuan; Edward Baran Aries; Kevin Kemudang; Joseph Wenceslaus; Lo Kim San; Lulie MellingCarbon dioxide (CO2) emission through accelerated peat decomposition is one of the main environmental concerns in the conversion of peatlands into plantations, which undergo drainage to increase palm growth rates and production. Changes in aboveground biomass might also significantly alter the CO2 exchange dynamics of the ecosystem. Despite the potential changes in CO2 balance due to land conversion, so far no study has been conducted using the eddy covariance technique about the CO2 balance of oil palm plantations established on peat. We have monitored the eddy CO2 flux above an oil palm plantation on peat in Sarawak, Malaysia since 2011.Item Restricted Interfuel substitution, hydroelectricity consumption and CO2 emissions mitigation in Malaysia: evidence from a transcendental logarithm (trans-log) cost function framework(Springer, 2020) Mufutau Opeyemi Bello; Sakiru Adebola Solarin; Yuen Yee YenThe main objective of this paper is to estimate the interfuel substitution elasticities between hydropower and the fossil fuels of coal and natural gas used in the generation of electricity for Malaysia.Item Restricted The effects of total factor of productivity, natural resources and green taxation on CO2 emissions in Malaysia(Springer, 2020) Nanthakumar Loganathan; Tirta Nugraha Mursitama; Lekha Laxman Kunju Pillai; Alam Khan; Roshaiza TahaThis study attempts to investigate the environment cleanness between the total factor productivity, natural resources and green taxation on Malaysia’s clean environment. Using the environmental Kuznets curve (EKC) hypothesis, this study employs the bootstrap quantile estimates based on the annual data series covering the period of 1970–2018 to analyse the quantile effect factors affecting environment cleanness in Malaysia.Item Restricted Revisiting the social cost of carbon after INDC implementation in Malaysia: 2050(Springer, 2019) Md. Sujahangir Kabir Sarkar; Abul Quasem Al-Amin; Walter Leal FilhoThis article projects the social cost of carbon (SCC) and other related consequences of climate change by using Malaysia’s intended nationally determined contribution (INDC) and climate vision 2040 (CV2040) by 2050. It compares the projections derived from the Dynamic Integrated Model of the Climate and Economy (DICME) based on the respective INDC and CV2040 scenario.Item Open Access Time-series maps of aboveground biomass in dipterocarps forests of Malaysia from PALSAR and PALSAR-2 polarimetric data(BioMed Central Ltd, 2018) Hamdan Omar; Muhamad Afzzul MismanMalaysia typically suffers from frequent cloud cover, hindering spatially consistent reporting of deforestation and forest degradation, which limits the accurate reporting of carbon loss and CO2 emissions for reducing emission from deforestation and forest degradation (REDD+) intervention. This study proposed an approach for accurate and consistent measurements of biomass carbon and CO2 emissions using a single L-band synthetic aperture radar (SAR) sensor system.Item Restricted Micrometeorological measurement of methane flux above a tropical peat swamp forest(Elsevier, 2018) Guan Xhuan Wong; Ryuichi Hirata; Takashi Hirano; Frankie Kiewa; Edward Baran Aeries; Kevin Kemudang Musin; Joseph Wenceslaus Waili; Kim San Lo; Lulie MellingOwing to the huge soil carbon stock and high groundwater level (GWL), tropical peatlands potentially represent a significant source of methane (CH4) to the atmosphere. However, a few studies of CH4 flux by the soil chamber technique have reported that annual CH4 emissions from tropical peat swamp forest were very low as compared to mid- and high-latitude peatlands. Recently, it has been reported that some tree species growing in peat swamp forest emit CH4 from their stems. It is impossible to continuously measure ecosystem-scale CH4 flux including both soil and plant-mediated CH4 emissions by the chamber technique. Thus, we have measured net ecosystem CH4 exchange (FCH4) above a tropical peat swamp forest in Sarawak, Malaysia using the eddy covariance technique from February 2014 to July 2015 (18 months).Item Restricted Carbon Emission Pinch Analysis: an application to the transportation sector in Iskandar Malaysia for 2025(Springer, 2018) Ahmad Fakrul Ramli; Zarina Ab Muis; Wai Shin Ho; Ahmad Muzammil Idris; Aminullah MohtarThe energy sector has grown significantly over the years, causing an increase in carbon emission that has led to serious global warming problems. Consequently, electric vehicles (EVs) have become a favourable solution in the transportation sector due to their green technology attributes. This paper aims to apply the Carbon Emission Pinch Analysis (CEPA) method to the transportation sector in Iskandar Malaysia.
