The carbon footprint of a knowledge organization and emission scenarios for a post-COVID-19 world
2021
Publisher Copyright: © 2021 The looming climate crisis requires an immediate response, in which organizations, as major contributors, should play a central role. However, these organizations need appropriate tools to measure and mitigate their climate impacts. One commonly applied method is carbon footprint analysis. Carbon footprint analyses have been conducted for various types of organizations, but knowledge organizations, such as universities and research institutes, have received far less attention, because their carbon footprint is often less visible and can be easily underestimated. This study is based on the carbon footprint analysis of one multinational knowledge organization. This…

Hiukkasmaisten hiilipäästöjen vaikutus ilmastoon
2016
Ilmakehän hiukkasmainen hiili on aerosolimuodossa esiintyvää hiiltä, joka on vapautunut ilmaan epätäydellisistä palamisprosesseista. Hiukkasmaisia hiiliyhdisteitä emittoituu erilaisista päästölähteistä, joista globaalisti tarkasteltuna suurin osa on ihmisperäisiä. Tarkastelemme miten alkuainemuotoisen mustan hiilen hiukkasemissiot absorboivat lämpösäteilyä maapallolla ja millainen vaikutus niillä on ilmastoon ja säteilytasapainoon. Suoran lämpöabsorption lisäksi mustan hiilen laskeuma tummentaa lumi- ja jääpeitteitä, mikä vähentää epäsuorasti albedon muutoksen kautta takaisin avaruuteen heijastuvan säteilyn määrää. Hiukkasen absorption ja sironnan voimakkuudet vaihtelevat partikkelin muodos…
Climate Change Mitigation Potentials of Carbon Labels in the Aviation Industry
2018
This chapter discusses the climate change mitigation potentials of carbon labels in the aviation industry. As this study shows, there are significant differences in the environmental performance of individual flights, even when operated on the same route or by the same airline. Selecting one flight over another can significantly reduce the carbon dioxide emissions of a single air passenger. Nevertheless, the currently available measures, such as carbon calculators, are not capable of presenting these differences, leaving air passengers with no means of comparing individual flights. Therefore, the use of carbon labels could be highly beneficial because it would give air passengers the opport…

Is there a convincing case for climate veganism?
2020
AbstractClimate change compels us to rethink the ethics of our dietary choices and has become an interesting issue for ethicists concerned about diets, including animal ethicists. The defenders of veganism have found that climate change provides a new reason to support their cause because many animal-based foods have high greenhouse gas emissions. The new style of argumentation, the ‘climatic argument(s) for veganism’, may benefit animals by persuading even those who are not concerned about animals themselves but worry about climate change. The arguments about the high emissions of animal-based food, and a resulting moral obligation to abstain from eating such products, are an addition to t…

Mismatch, Empowerment, Fatigue or Balance? Four scenarios of physical activity up to 2030 in Finland
2022
Sedentary lifestyles and the lack of physical activity (PA) are a major concern among all age groups, and current generations tend to be less fit than the previous ones in the Western World. At the same time, there is an urgent need to cut transport-related carbon dioxide (CO2) emissions. Major gains can be foreseen if current car-centred lifestyles and sedentary behaviour are addressed from an integrated perspective. In this study, we explore future scenarios in the intersections of PA and active lifestyles as well as related environmental and health benefits in Finland. We used a disaggregative Delphi approach to examine the topic. Although frequently used in health-related research, Delp…
