    Enhancing the Understanding of climate dynamics: analysis of global warming’s influence on Climatic changes across continents
    (Springer Science and Business Media, 2025-07-14) Dharmapriya, N; Edirisinghe, S; Gunawardena, V; Methmini, D; Rathnayake, N; Jayathilaka, R
    Global warming, primarily due to increased atmospheric carbon dioxide, poses a significant threat to climate stability, yet research on its combined effects across different geographical areas is limited. In order to fill that gap, this study examines how carbon emissions (CE) are impacted by greenhouse gas emissions (GHG), agricultural nitrogen oxide (ANO), urban population (UP), and fossil fuel consumption (FFC) in 185 different nations between 2000 and 2019. With the exception of urban population, which was expressed as a percentage, all variables were standardised to metric tonnes per capita using panel regression analysis. The results draw attention to geographic disparities. Africa has the lowest carbon and greenhouse gas emissions due to its extensive forest cover and minimal industrial production. Although Oceania’s greenhouse gas emissions have decreased, the region continues to emit high amounts of agricultural nitrous oxide. Rapid industrialisation is the primary cause of Asia’s growing consumption of fossil fuels. Agricultural nitrous oxide and carbon emissions have a negative correlation in Asia, Oceania, and the globe, but a positive correlation in Africa, America, and Europe. Carbon emissions and the use of fossil fuels are strongly positively correlated in every region but Asia. These results highlight the complex, location-specific factors affecting carbon emissions. For policymakers to effectively cut emissions, they must develop customised, geographically specific initiatives. In order to accomplish Sustainable Development Goal 13: Climate Action by 2030, emission controls should be strengthened, and sustainable practices should be encouraged, particularly in the use of fossil fuels and farming.

    Regional emissions and climate impact: analysing carbon dioxide and methane effects on temperature and sea levels in Asia
    (Springer, 2025-10-26) Punchihewa, C; Liyanage, S; Badurdeen, S; Gunaratne, T; Jayathilaka, R
    Climate change and its impacts are felt worldwide, and with increasing anthropogenic emissions, many international efforts are centred around mitigating emissions and meeting climate targets. The Asian continent has made the most significant contributions to global emissions, with China, India, and Russia generating the largest share of emissions. Given Asia’s vulnerability to climate change, the study addresses the literature gap by examining the regional impact of anthropogenic carbon dioxide (CO2) emissions and methane (CH4) emissions on mean surface temperature (MST) and the effects of MST on mean sea levels (MSL) through panel regressions focusing on the period from 1993 to 2020, considering 45 countries. The study found that regional CO2 and CH4 emissions had a significant positive impact on MST at a 1% significance level, and MST had a positive impact on MSL at a 5% level of significance. The study has focused on continental sources of anthropogenic emissions and applied econometrics over traditional climate models to enable a more nuanced, granular, region-specific understanding of emission impacts for targeted policy development. It has proposed targeted policy measures to mitigate emissions, highlighting the importance of regional collaboration among Asian countries in achieving emission reduction goals.

    Global warming potential of English brick manufacturing in Sri Lanka: A cradle to gate analysis
    (IEEE, 2021-07-27) Herath, I; Karunaratne, S; Dharmarathna, D
    Clay bricks are one of the most commonly used walling materials in Sri Lanka. The brick manufacturing process poses a notable impact on the environment. Clay excavation leads to resource depletion while diesel fuel utilized for excavation and clay transportation pollutes the air. Additionally, tree cutting for wood fuel contributes to deforestation whilst wood burning promotes air pollution. Thus, this research aimed to quantify the global warming potential due to English brick manufacturing using cradle to gate Life Cycle Assessment (LCA) approach. The functional unit used was one-meter square of the brick wall area. Data collection, analysis and interpretation of results were done by the ISO 14044/14040 standards. Primary life cycle inventory data was gathered via brick kiln owners and workers. The LCA assembly was modelled using the ‘OpenLCA’ software. Three product systems were defined according to the brick bond types and wall thicknesses. The global warming potential related to brick production was assessed using the ‘GWP 100a’ method. Clay excavation, clay transportation and wood chamber firing emerged as emission hotspots. The study revealed that the global warming potential of 225mm brick wall and 115mm brick wall as 11.9 and 5.9 kg CO2-eq/m 2 , respectively. Through this study, local clay brick industry can be driven to improve the overall sustainability of the brick manufacturing sector.
