How did we assess the outcomes of tradable green certificates? A review

When policy support schemes are in reevaluation process, academic literature play pivotal role. This paper presents a literature review of studies that have assessed the performance of Tradable green certificates (TGC) schemes in stimulating investments in Electricity from Renewable Energy Sources (RES-E). To do so, we conduct an extensive and systemic literature review on the Web of Science database. This paper?s outcomes in addition to the descriptive statistics that provide an overview of the publications, intend to gain insights in two important aspects. First, we categorize the typical research approaches (i.e. analysis criteria) to the assessment of TGC systems performance in different, mainly European countries and summarize their outcomes. Second, we illustrate which of research approaches have had the highest impact on the literature of its nature, based on the average number of citations. This paper provides several intriguing direction for future studies
