(2021)This article analyses ways to maintain reservoir sustainability in the area surrounding the Blue Lagoon in Iceland, near the urban settlement of Grindavík on the Reykjanes Peninsula in Iceland. The Svartsengi geothermal power plant operations have ... -
(MDPI AG, 2016-11-08)The greenhouse gas (GHG) emissions caused by tourism have been studied from several perspectives, but few studies exist that include all direct and indirect emissions, particularly those from aviation. In this study, an input/output-based hybrid ...
-
(Elsevier BV, 2020-12-01)This study presents a comparison of the life cycle carbon emission (LCCO2) and embodied energy calculation between two kinds of bricks, sun-dried and fired clay, as means of evaluating the energy and climate impact of each brick type and the economics ...
-
(Elsevier BV, 2020-12)Human economic activities and following carbon emissions have been recognized to be a real threat to the environment. The current levels of consumption-based carbon footprints in all developed economies grossly exceed the sustainable level. Scientists ...
-
(Taiwan Association for Aerosol Research, 2020-05)In order to decrease spreading of Coronavirus disease 2019 (COVID-19) over the world, the activity of many industries has declined, several flights were cancelled and so many people staying home that made drop in fuel consumption in road transport. ...
-
(Agricultural University of Iceland, 2018)Geothermal areas can be local sources of greenhouse gases, both directly from the geothermal system or because of soil warming effects on biological sources. In this study we repeated field measurements methane (CH4) and nitrous oxide (N2O) fluxes along ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2021-08-27)Buildings are the key components of urban areas and society as a complex system. Traditionally, the emissions embodied in construction materials have not been considered important, in comparison with impacts from the energy use when it comes to mitigating ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2021-08)The consumption activities of urbanites contribute to an ever-increasing share of greenhouse gas emissions and resource depletion. As urban form influences behaviours, the search for the most sustainable type of urban form is a research topic of interest. ...
-
(MDPI AG, 2019-11-12)Transport is a key sector in reducing greenhouse gas (GHG) emissions. A consensus prevails on a causal relationship between distance to the city center and emissions from private transport, which has led to an emphasis on density in urban planning. ...
-
(MDPI AG, 2019-04-24)A lot of emphasis has been put on the densification of urban form to reduce greenhouse gas emissions from transportation. However, many recent studies have found that central urban dwellers, even though their carbon footprints of daily transportation ...
-
(MDPI AG, 2020-06-19)The European Union (EU) has made climate change mitigation a high priority though a policy framework called "Clean Energy for all Europeans ". The concept of primary energy for energy resources plays a critical role in how different energy technologies ...
-
(MDPI AG, 2020-03-20)Some cities have set carbon neutrality targets prior to national or state-wide neutrality targets, which makes the shift to carbon neutrality more difficult, as the surrounding system does not support this. The purpose of this paper was to evaluate ...
-
(Unigrafia, Helsinki, 2016-11)Climate change mitigation in the built environment encompasses various mitigation measures, such as energy efficient buildings, spatial planning instruments and other policies targeting the emissions resulting from transport. However, studies on the ...
-
(2020-11-02)Electric vehicles (EVs) are often considered a potential solution to mitigate greenhouse gas (GHG) emissions originating from personal transport vehicles, but this has also been questioned due to their high production emissions. In this study, we ...
-
(Elsevier BV, 2019-10)Transition to electric vehicles (EVs) requires multidimensional policy measures incorporating vehicle fleets, energy systems, consumer behaviours, and socio-economic developments. The main objective of this paper is to evaluate the implications of a ...
-
(Springer Science and Business Media LLC, 2020-08-13)How mercury flows from geological sources to society and to the environment was modelled for this study. The industrial dynamics of mercury was modelled and included in the integrated assessment model WORLD7. The simulated mercury losses were used as ...
-
(Wiley, 2020-01-08)Since 2009, one out of five European airports participate in carbon dioxide (CO2) reduction programmes, although only 8% of them are certified as CO2 neutral. This study aims to examine empirically internal as well as external factors of importance for ...
-
(University of Iceland, 2021-11-05)Our world is struggling with the negative impacts of greenhouse gases, with CO2 constituting more than ¾ of them. The ammonia production through the Haber-Bosch process which is vital for the sustain of human beings by ensuring food security, accounts ...

Urban sustainability? The spatial disparities of greenhouse gas emissions and subjective wellbeing (University of Iceland, School of Engineering and Natural Sciences, Faculty of Civil and Environmental Engineering, 2017-05-05)Cities are engines of growth and productivity. In addition, great expectations are set upon these agglomerations to contribute to development that meets the needs of the present without compromising the ability of future generations to meet their own. ...
