Deep-sea mining (DSM) may become a significant stressor on the marine environment. The DSM industry should demonstrate transparently its commitment to preventing serious harm to the environment by complying with legal requirements, using environmental good practice, and minimizing environmental impacts. Here existing environmental management approaches relevant to DSM that can be used to improve performance are identified and detailed.

Coral reefs are one of the world’s most biologically diverse and productive ecosystems. However, these valuable resources are highly threatened by human activities. Satellite remotely sensed observations enhance our understanding of coral reefs and some of the threats facing them by providing global spatial and time-series data on reef habitats and the environmental conditions influencing them in near-real time.

The present study, commissioned by the French Agency for Biodiversity (Agence française pour la biodiversité, AFB), is part of the "Pacific Biodiversity Blue Belt" project. It covers four Pacific island Overseas Countries and Territories (OCTs): French Polynesia (PF), New Caledonia (NC), Wallis & Futuna (WF) and Pitcairn (Pi). These French (PF, NC and WF) and British (Pi) territories are characterised by vast maritime areas and geographical isolation from their home States.

For tropical forest carbon to be commoditized, a consistent, globally verifiable system for reporting and monitoring carbon stocks and emissions must be achieved. We call for a global airborne LiDAR campaign that will measure the 3-D structure of each hectare of forested (and formerly forested) land in the tropics. We believe such a database could be assembled for only 5% of funding already pledged to offset tropical forest carbon emissions.
