Regulators and advisors involved in consenting/permitting marine renewable energy (MRE) have faced multiple challenges due to the unfamiliarity with relatively new technology and uncertainty surrounding potential environmental impacts. This has resulted in slow progress for the MRE industry, including long consenting timeframes and extensive and expensive consenting/permitting requirements, which increase financial risk for investors. OES-Environmental has surveyed regulators internationally to understand environmental concerns and key knowledge and outreach gaps to better engage with regulators and advisors to support the development of the MRE industry worldwide.

OES-Environmental has adapted its survey questions from those used in its first survey, which was deployed in the United States in 2017. The survey results have been analyzed and described in a report for each country and additional reports will be published as the survey is completed for other OES-Environmental countries.

- United States (2017)
- United Kingdom (2018)
- Sweden (2018)
- Spain (2018)
- France (2019)

The results from these surveys have been used to inform the development of the data transferability and risk retirement concepts in addition to the outreach strategy of OES-Environmental, and have been published in a conference paper (Freeman et al. 2020) and a journal article (Rose et al. 2023).
