The ocean – our biggest ally against climate change – is in serious trouble. To jumpstart solutions to protect the planet and open a new chapter of global ocean action, world leaders and ocean advocates will gather in Lisbon, Portugal, from 27 June to 1 July, for the second UN Ocean Conference.

Our world’s greatest ally against climate change

… and did you also know that our ocean generates 50 percent of the oxygen we need, absorbs 25 percent of all carbon dioxide emissions and captures 90 percent of the excess heat generated by these emissions? It is not just ‘the lungs of the planet’ but also its largest ‘carbon sink’ – a vital buffer against the impacts of climate change.

UN Ocean Conference

The Ocean Conference, co-hosted by the Governments of Kenya and Portugal, comes at a critical time as the world is seeking to address many of the deep-rooted problems of our societies laid bare by the COVID-19 pandemic and which will require major structural transformations and common shared solutions that are anchored in the SDGs. To mobilize action, the Conference will seek to propel much needed science-based innovative solutions aimed at starting a new chapter of global ocean action.

Plastic pollution in the world's oceans is threatening marine life

Life below water

The oceans are the most prominent feature on the planet, covering nearly three quarters of the Earth, and are essential for planetary survival. Just as a person cannot live without a healthy heart and lungs, the Earth cannot survive without healthy oceans and seas. They serve as the Earth’s respiratory system, producing oxygen for life and absorbing carbon dioxide and waste. The oceans provide storage and absorb the world’s carbon dioxide, while marine phytoplankton generates the oxygen needed for survival.
