OES-Environmental (formerly known as Annex IV) was established by the International Energy Agency (IEA) Ocean Energy Systems (OES) in January 2010 to examine environmental effects of marine renewable energy (MRE) development. The U.S. Department of Energy (DOE) leads the tasks for the United States, partnered with the U.S. Bureau of Ocean Energy Management (BOEM) and the U.S. National Oceanic and Atmospheric Administration (NOAA). OES-Environmental is implemented by Pacific Northwest National Laboratory (PNNL) and acts as the Operating Agent. Tethys acts as the platform on which OES-Environmental activities are coordinated and recorded.
MRE is an emerging industry that faces regulatory challenges associated with potential environmental impacts, around which there is a high degree of uncertainty. OES-Environmental mobilizes information and practitioners from OES nations to coordinate research that can progress the industry in an environmentally responsible manner. A key component of this effort involves making existing information available and accessible.

OES-Environmental Webinars and Workshops
OES-Environmental hosts webinars featuring international experts on environmental effects of importance to the MRE industry as a means to effectively disseminate new information and research efforts across a large international stakeholder audience. You can sign up to receive invitations to live webinars here. Past webinars are archived on Tethys, along with the associated video and presentations as available, and can be found here.
OES-Environmental organizes workshops, often in conjunction with conferences, focused on specific aspects of environmental effects of MRE. Recordings, presentations, reports, and descriptions from these workshops can be found here.
OES-Environmental hosts metadata forms (questionnaires) that solicit information from project developers and researchers involved in deploying and monitoring MRE devices and/or carrying out pertinent research. These forms capture activities that explore the potential environmental impacts of MRE devices around the world, and often provide links to associated reports and papers. This information on project sites and research studies is made publicly available on the OES-Environmental Metadata page.
OES-Environmental requests updates to these forms on an annual basis to ensure that the information is reliable and accurate. If you are interested in submitting a metadata form, please fill out one of the following forms and send it to email@example.com.
Tools and Resources
OES-Environmental has developed the following tools to provide information that may be useful for addressing many activities around environmental consenting/permitting. All are hosted on Tethys:
- Regulatory Frameworks: A high-level summary of country-specific requirements for environmental consenting/permitting of MRE devices (specifically wave and tidal) was collected for member countries of OES. This information is intended for general informative purposes only.
- Data Portal: This list includes references to environmental post-installation monitoring datasets conducted around marine renewable energy device deployments. The data may be accessible at an external website or from a listed point of contact.
- Management Measures Tool: This tool was designed based on input from researchers, regulators, and developers at a workshop organized by OES-Environmental held May 9th 2017 in Glasgow UK. The tool provides recommendations for a set of robust management measures might act as safeguards for marine animals and habitats until such time as definitive monitoring data become available to determine the level of risk from turbines and WECs.
- Monitoring Datasets Discoverability Matrix: This tool, the matrix, classifies monitoring datasets from already consented projects for six stressors (collision, underwater noise, electromagnetic fields, habitat change, displacement/barrier effects, changes to physical systems). The matrix will allow regulators and/or developers to discover datasets and evaluate the consistency of information from an already consented project that will allow for the transfer of data to future projects.
Tethys supports collaborative interactions among researchers, developers, regulators, and stakeholders for responsible development of marine energy. Notably, the Ocean Energy System's OES-Environmental initiative is supported by Tethys.

History of OES-Environmental
OES-Environmental began in 2010 and has progressed through three phases, as summarized below. A more detailed layout of the phases and timeline is available here.
Phase 1: 2010-2013
OES-Environmental (the task formerly known as Annex IV) member countries collaborated to create a searchable, publicly available database of research and monitoring information to evaluate environmental effects. The database, housed in the Tethys Knowledge Base, includes data from MRE projects, research studies and case study reports. Two international scientific workshops were held to provide input for the database and to inform the 2013 Final Annex IV Report.
Partner Nations (6):
Phase 2: 2013-2016
OES-Environmental (the task formerly known as Annex IV) was continued for a second phase, continuing the collection, analysis, and dissemination of information on environmental effects of MRE development. During Phase 2, additional emphasis was placed on creating a collaborative space or commons for interaction among researchers, developers, regulators, and stakeholders. Phase 2 culminated with the preparation of the 2016 State of the Science Report, and partnership with the EWTEC 2015 international conference.
Partner Nations (13):
Phase 3: 2016-2020
OES-Environmental was approved for a 4-year extension consisting of three interrelated tracks: (1) information gathering and analysis, (2) information dissemination, and (3) engaging the community to support research and monitoring needs. Phase 3 culminated with the completion of the 2020 State of the Science Report.
Partner Nations (15):
Phase 4: 2020-2024
Approval for Phase 4 is pending.
