Ripepi, D. (author)In the last century, the indiscriminate use of fossil energy to power the industrial revolution and technological progress of humankind, has led to the depletion of limited natural resources and, most importantly, the emission and accumulation of alarming levels of pollutants and greenhouse gases (GHG) in the atmosphere. One of the major...doctoral thesis 2023

Orobio de Castro, Samuel (author)In 2022, the Netherlands are confronted by two major problems: a housing shortage and an excess of nitrogen emissions. This excess of nitrogen emissions is primarily the result of livestock farms, which cause problems in close proximity to Natura 2000 areas. The housing- and nitrogen crises are intertwined because certain housing developments...master thesis 2023

Johne, C. (author), Schröder, E. (author), Ward, H. (author)The high level of nitrogen emissions over the last decades and their adverse impact on the natural environment and human health are a pressing environmental issue. A nitrogen tax can be a cost-efficient and effective policy instrument to reduce nitrogen emissions. However, adverse effects on low- and middle-income households might lead to...journal article 2023
