The big news also is that they are making sure it is the right 30%. The IUCN wrote about that here:

TITLE: We need to protect and conserve 30% of the planet: but it has to be the right 30% https://www.iucn.org/crossroads-blog/202108/we-need-protect-and-conserve-30-planet-it-has-be-right-30

QUOTE STARTS

Between 2010 and 2020, the expansion of protected areas was biased toward locations that were remote and less suitable for agriculture, rather than areas of importance for species and ecosystems. As momentum to protect 30% of the planet’s surface by 2030 builds, Key Biodiversity Areas (KBAs) are our best tool when deciding which places to protect, write representatives of institutions in the KBA partnership.

• G7 leaders endorse protecting and conserving 30% of the planet.
• President of the United States Joe Biden pursues a target of 30% protection by 2030.
• EU commits to protecting 30% of land and sea under new Biodiversity Action Plan.

These and similar headlines have been appearing in the press in recent months. There is growing support for conserving at least 30% of our planet by the year 2030 to halt biodiversity loss and the degradation of important ecosystem services, and move towards a nature positive future; whilst recognising and safeguarding the rights of indigenous peoples and local communities, and their rights to land and resources.

The effectiveness of such a target depends on whether we are conserving the “right” places, but determining the right places has historically been challenging for national governments without standardised guidance from scientists and other conservation experts.

Areas are often designated as protected where it is convenient rather than because they are important for conserving biodiversity.

While a percentage target for protected and conserved areas is simple, measurable, and can help gain political and public traction; areas are often designated as protected or conserved where it is convenient rather than because they are important for conserving biodiversity. Protected areas tend to be created in remote places, at high elevations, and in locations that are less likely to be developed for agriculture.

Since 2010, protected areas have increasingly been created in places that are not sites of global biodiversity importance. If this trend continues, we will undoubtedly keep losing biodiversity even while achieving area-based targets. The solution is to ensure that plans to meet these targets comprehensively incorporate areas of importance to the persistence of biodiversity. Key Biodiversity Areas (KBAs) are recognised as sites of global importance for biodiversity, and should be used to guide where protected and other conserved areas are established.

That's been turned around with this new agreement.

The key points were:

• Effective conservation and management of at least 30% of the world’s lands, inland waters, coastal areas and oceans, with emphasis on areas of particular importance for biodiversity and ecosystem functioning and services. The GBF prioritizes ecologically-representative, well-connected and equitably-governed systems of protected areas and other effective area- based conservation, recognizing indigenous and traditional territories and practices. Currently 17% and 10% of the world’s terrestrial and marine areas respectively are under protection.
• Have restoration completed or underway on at least 30% of degraded terrestrial, inland waters, and coastal and marine ecosystems
• Reduce to near zero the loss of areas of high biodiversity importance, including ecosystems of high ecological integrity
• Cut global food waste in half and significantly reduce overconsumption and waste generation
• Reduce by half both excess nutrients and the overall risk posed by pesticides and highly hazardous chemicals
• Progressively phase out or reform by 2030 subsidies that harm biodiversity by at least $500 billion per year, while scaling up positive incentives for biodiversity’s conservation and sustainable use
• Mobilize by 2030 at least $200 billion per year in domestic and international biodiversity-related funding from all sources – public and private
• Raise international financial flows from developed to developing countries, in particular least developed countries, small island developing States, and countries with economies in transition, to at least US$ 20 billion per year by 2025, and to at least US$ 30 billion per year by 2030
• Prevent the introduction of priority invasive alien species, and reduce by at least half the introduction and establishment of other known or potential invasive alien species, and eradicate or control invasive alien species on islands and other priority sites
• Require large and transnational companies and financial institutions to monitor, assess, and transparently disclose their risks, dependencies and impacts on biodiversity through their operations, supply and value chains and portfolios…

Emphasized throughout the approved documents are the needs to foster the full and effective contributions of women, persons of diverse gender identities, youth, indigenous peoples and local communities, civil society organizations, the private and financial sectors, and stakeholders from all other sectors.

Also emphasized: the need for a “whole-of-government and whole-of-society approach” to implementing the GBF.
