This study focuses on PFAS-pollution, specifically the pollution situation for four objects in Svedala municipality. Per- and Polyfluorinated Chemicals (PFAS) has been used widely since the 1950s and spread because of anthropogenic activities, due to their characteristics, such as dirt-, grease, and water repellent properties in cosmetics, textiles and fire extinguishers. PFAS has shown to be pers
The start-up company LEVTEK is launching a new ultralight electric utility vehicle called the LEVKART. The Levkart uses a combination of robotics and AI-technology to offer semi-autonomous or autonomous riding and usage. The purpose of the vehicle is to serve as an alternative to cargo bikes and electric scooters designed for easy usage and as a more sustainable option to fossil-based transport. T
Society's increased demand for wood has led to amplified extraction of forests, which has negatively affected the preservation of biological diversity. In Sweden, the world's fourth largest wood exporter, forest conservation legislation is based on freedom with responsibility, which means that forest owners are expected to take personal responsibility for the consideration of the forest
Drained peatlands in Sweden emit approximately 11 tons of carbon dioxide equivalents annually. Attempts to rewet to eliminate emissions have shown that the irreversible processes of peat oxidation in the form of peatland deposition makes it hard, since it instead greatly increases methane gas emissions. This study presents a literature review of the environmental consequences of peat and peatland
Carbon emissions from the transport sector are one of the main drivers of climate change, and electrified transportation is one attempt to reduce the sector’s climate impact. Levtek Sweden AB is a start-up company developing the Levkart, a lightweight and autonomous four wheeled vehicle. To aid Levtek in developing a sustainable vehicle, this thesis aims to investigate the environmental impact of
Mitigation of climate change as the main goal of the Paris Agreement aims to keep the global mean temperature at 1.5 Celsius. As of now daily global temperature are surpassing this threshold which indicates the urgency to reenact more work in limiting green house gas emissions and at the same time optimize sequestration of carbon dioxide already in the atmosphere. One key instrument to sequester c
In May 2023, the EU adopted a crucial part of their updated climate policy, the Carbon Border Adjustment Mechanism (CBAM). This thesis poses questions about how this novel legislation affects the EUs South-Eastern neighbours, the Western Balkans (WB). The relevance for applied climate change strategies lies in the policy-oriented approach to a new type of international climate policy. Previous res
Wildfires causes natural disturbances to ecosystems which can have potentially damaging results for ecosystem services and economic income from timber production. The post-fire management approach can be essential for the environmental work regarding the recovery of ecosystems and maintaining ecosystem services. The aim of this study was therefore to evaluate different post-fire management approac
Achieving a transport emission reduction in line with global reduction targets is considered as one of the greatest environmental challenges societies are facing today. As car use continues to increase, there is a need to better understand what influences individuals' choice of transportation and how to bring about behavioural change where fewer choose to travel by car. This study addresses th
Linear transportation infrastructure such as powerlines generate documented adverse effects on biodiversity. However, the potential of powerline corridors to constitute habitats, a dispersal corridor, or as potential to create value for biodiversity remains somewhat controversial. This case study investigates what the drivers and challenges are to create value for biodiversity combined with the p
Browning of water has increased over the last couple of decades on the northern hemisphere. Research show that possible drivers for this change are land use change, climate change, increased precipitation and increased temperatures. Browning of water can affect important interactions in the aquatic ecosystem which in turn can affect the whole structure of the ecosystem. Furthermore the loss of a t
Biofuels are seen as a key substitute for fossil fuels and an essential tool for mitigating climate change. A sensitivity analysis was conducted on the AB-LCA (agent-based life cycle assessment) made by Raül López i Losada and his research team. Their AB-LCA assesses the environmental performance of a subsidy that generates an allocation of the arable land in Götalands Södra Slättbygder (GSS) that
The pulp industry is important for creating sustainable paper products and for the Swedish economy. However, the industry has historically polluted marine environments through its emissions. This study aims to analyse the effects of the pulp mill Södra Cell Mörrum on the marine recipient Hanö Bay in the southern Baltic Sea. The study focuses on effects of nutrients and metals on sediments and blue
Large amounts of plastic in the oceans originate from mismanaged plastic waste, and microplastics (MPs) are the most common type of waste. They can be found in household products, such as sea salts. Therefore, monitoring pollution levels is essential to improve marine health and food safety. This study examined the MP levels in salts produced from the North Atlantic and North Seas and analyzed the
The consequences of climate change and increasing disasters jeopardise the livelihoods and resilience of some of the world’s most vulnerable countries. Strengthened international efforts to mobilise and allocate additional climate and disaster resilience financing are required to address the needs of the countries that have least contributed to climate change and who currently are at the forefront
Today, 86% of children between the age of 1 and 5 are enrolled in preschools in Sweden. The outdoor environment is important to support children’s development, health, and wellbeing. Children’s perception of what an appropriate outdoor environment is often differs from what adults consider to be a god and healthy outdoor environment. The aim of this study is to confirm the gap in supervision
The demand for biofuels is increasing as a result of increased climate mitigation ambitions aiming to replace the use of fossil fuels. To meet the increasing demand, energy crops grown on agricultural land used to produce biofuels is getting more and more attention. Since agricultural land is a scarce resource, conflicts can arise between food production and biomass for biofuels, making it essenti
The spread of artificial light on Earth increases annually. One of many causes of this spread is due to increased street lighting and artificial light at night (ALAN). Lighting is one of the many necessities for people to feel safe. On the other hand, ALAN, which contributes to light pollution, negatively affects biological functions and thus biodiversity. The purpose of this study was to investig
Recycling has become increasingly relevant to solve environmental problems related to the enormous amount of plastic waste. Recycling plastic has many environmental benefits, but it is challenging to find applications where recycled plastic can provide the same functionality as virgin plastic. This thesis highlights the challenges of using recycled High-density polyethylene (HDPE) in pipe applicat
This study was done to get an understanding of how tillage effects biodiversity in agriculture soil. Therefore, this study focused on the soil organisms and various physical and chemical processes that can affect them. Soil organisms are crucial to agricultural landscapes as they perform biological processes that improve soil structure, nutrient cycling and decomposition. To ensure food produc
