Despite high estimated economic gains the implementation of a circular economy (CE) in most areas is generally slow. The purpose of this paper is therefore to examine the potential causes to this sluggish implementation and to discuss and illustrate how different types of barriers (technological, market, institutional and cultural) can prevent the further implementation of a CE. We conduct a systematic literature review where academic articles and "grey literature" on the barriers to a CE transition are analysed and classified into technological, market/economic, institutional/regulatory, and cultural/social barriers. We approach the research problem in a twofold way. Firstly, we recognize the barriers that currently seem to hinder a CE from developing. Secondly, we map these barriers to better understand how they are interdependent and entangled. Our main conclusion is that even small barriers can stop the emergence of a CE.

The purpose of this paper is to provide a global overview of job effects per MW of wind power installations, which will enable improved decision-making and modeling of future wind-power projects. We found indications that job creation connected to wind-power installations is rather limited. In total, 17 peer-reviewed articles and 10 reports/non-peer-reviewed papers between 2001 and 2019 were assessed. Our three major policy conclusions are as follows: (a) job creation seems to be limited; (b) each new project should consider a unique assessment, since all projects have been undertaken within different institutional frameworks, labor markets, and during separate years, meaning that the technology is not comparable; and (c) the number of jobs depends on the labor intensity of the country.Employment opportunities are a key consideration in planning for low-carbon economic growth. Many governments have prioritised renewable energy development, firstly to reduce emissions and meet international climate goals, but also in pursuit of broader socio-economic benefits.
