October/November 2022

July/August 2022


  • Stated that they are not supporting Belgium’s proposal but do see merit in the proposals and would be interested in the proposals from Australia and the Netherlands.


  • Tonga stated that they “had not had ample time to coordinate this request with capital, so there is a sense of uneasiness, without receiving proper direction, however, I recognize the intent of the proposal is to open discussion but we recognize that we are still in the middle of two-year rule so there is still time to take action. I feel that in due course we will have to come to that in terms of trying to force the way forward after the two-year period.”
  • They also stated that sea levels will continue to rise and that SIDS are more vulnerable with current baselines threatened.


  • Stated that they were not in favor of including the word “relevant” or “adjacent” commenting It is not clear how these would be determined stating that “Article 142 of UNCLOS provides rights for coastal states across whose jurisdiction resource deposits lie. Tonga does not consider that the Authority is required to consult prior to developing measures to implement the regulations. The powers of the ISA to create and adopt rules, regulations, and procedures are outlined in the convention. It would be inappropriate to restrict powers by way of regulations.”
  • The DSCC commented that scientific research has shown that sediment from the discharge plume can travel over 1,400 km, so using the word adjacent may not cover all affected States, and therefore potentially affected states may therefore not be adjacent.
  • Earthworks stated that they did not know why the regulations would not include relevant coastal states broadly due to impacts on the wider pacific, impacts on migratory populations of tunas and turtles could be affected by mining activities in the CCZ.


  • Tonga stated that they were “concerned by the apparent lack of progress with respect to the identification and preparation by the Commission of the phase two standards and guidelines.”
