As we head to UNFCCC COP31 climate negotiations, read our briefing on marine geoengineering.

Marine geoengineering carries significant risks for ocean ecosystems, and livelihoods. Large-scale interventions can lead to unintended and irreversible consequences in geoengineering carries significant risks for ocean natural ocean processes. The extensive deployment of these technologies raises serious concerns about long-term environmental sustainability and global equity.

We, as representatives from civil society, Indigenous Peoples, and grassroots organizations from around the world therefore call on governments and COP31 Presidencies to:

  • Uphold the long-standing and repeatedly reaffirmed de facto moratorium on all climate geoengineering approaches, including marine carbon dioxide removals, under the Convention on Biological Diversity, noting the Rio Synergies agenda, and the ICJ Climate Change Advisory Opinion affirming that States must consider their obligations under other international environmental treaties when taking climate action and interpret their obligations under international law harmoniously.
  • Avoid vague terminology such as Ocean Climate Solutions and Ocean Climate Technologies in COP31 decisions to shut down any loopholes for marine carbon dioxide removals/geoengineering proponents to exploit
  • Exclude marine carbon dioxide removal credits and all CDR credits from Article 6 mechanisms and Nationally Determined Contributions accounting
  • Urgently prioritize real solutions to the climate crisis, including a just and equitable phase-out of fossil fuels, a halt to offshore oil and gas activities, and grant- based ocean climate finance aligned with fair shares, rather than offsets.
