30 by 30

30 by 30 (or 30x30) is a worldwide initiative for governments to designate 30% of Earth's land and ocean area as protected areas by 2030. The target was proposed by a 2019 article in Science Advances, "A Global Deal for Nature: Guiding principles, milestones, and targets", highlighting the need for expanded nature conservation efforts to mitigate climate change. Launched by the High Ambition Coalition for Nature and People in 2020, more than 50 nations had agreed to the initiative by January 2021, which has increased to more than 100 countries by October 2022. US$5 billion in funding for a project called the "Protecting Our Planet Challenge" was announced for the initiative in September 2021. In December 2022, 30 by 30 was agreed at the COP15 meeting of the Convention on Biological Diversity, and became a target of the Kunming-Montreal Global Biodiversity Framework. This includes the G7 and European Union. The initiative has attracted controversy over indigenous rights issues. 30 by 30 is the third of 23 global biodiversity targets for 2030 in the Kunming-Montreal Global Biodiversity Framework, adopted in December 2022: Ensure and enable that by 2030 at least 30 per cent of terrestrial, inland water, and of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem functions and services, are effectively conserved and managed through ecologically representative, well-connected and equitably governed systems of protected areas and other effective area-based conservation measures, recognizing indigenous and traditional territories, where applicable, and integrated into wider landscapes, seascapes and the ocean, while ensuring that any sustainable use, where appropriate in such areas, is fully consistent with conservation outcomes, recognizing and respecting the rights of indigenous peoples and local communities, including over their traditional territories. The European Commission's Biodiversity strategy for 2030 was proposed on May 20, 2020, as the European Union's contribution to a post-2020 global biodiversity framework.
