Warmer water holds less dissolved oxygen, and nutrient pollution from land leads to algal blooms that consume oxygen when they decompose, both contributing significantly to deoxygenation.

Ocean deoxygenation refers to the alarming decline in the amount of dissolved oxygen in the world's oceans.

The consequences of not meeting the GBF targets include the permanent extinction of species and the degradation of ecosystems, which undermines ecological stability and human well-being.

The framework recognizes the crucial role of indigenous peoples and local communities in biodiversity conservation and stresses the need to uphold their rights and ensure equitable benefit-sharing.

Mobilizing sufficient financial resources, especially for developing countries, is a significant obstacle to effectively implementing the ambitious targets set by the GBF.

The '30x30' target is a cornerstone of the GBF, aiming to conserve and protect at least 30% of the planet's terrestrial, inland water, coastal, and ocean areas by the year 2030.

The GBF is a global agreement aimed at significantly reducing and ultimately reversing the decline of biodiversity by the end of the current decade.

By transforming captured CO2 into valuable products, utilization can foster new economic activities, create employment opportunities, and contribute to a more circular carbon economy.

Industries like cement, steel, and chemicals have process emissions that are difficult to eliminate through electrification alone, making CCUS a critical technology for their decarbonization.

The 'Storage' component of CCUS involves injecting captured CO2 into deep underground geological formations, such as depleted oil and gas reservoirs or saline aquifers, for long-term sequestration.
