Planetaarsete piiride kontseptsioon

The report examines the planetary boundaries concept, which identifies nine bio-physical systems essential to human stability. It notes that as of 2023, six of these nine boundaries have been exceeded globally. The document explores the difficulty of 'downscaling' these global limits to national levels, discussing various allocation principles such as equality, needs, and sovereignty. It specifically evaluates the potential for Estonia to calculate its 'own share' of these boundaries to inform national environmental policy, while highlighting significant data gaps and the lack of a harmonized EU-wide methodology.

• The planetary boundaries framework identifies nine critical bio-physical systems: biodiversity, climate change, stratospheric ozone depletion, chemical pollution, ocean acidification, freshwater consumption, land-use change, nitrogen and phosphorus cycles, and atmospheric aerosols.
• While only three boundaries (nitrogen cycle, climate change, and biodiversity) were exceeded when the concept was introduced in 2009, recent 2023 analysis indicates that six of the nine boundaries have now crossed their thresholds.
• Translating global boundaries to a national level requires choosing a 'fair share' allocation principle; common approaches include equality (based on population share), needs, the right to develop, sovereignty, and payment capacity.
• The 'Doughnut Economics' model expands the planetary boundaries framework by adding a social foundation, creating a 'safe and just operating space' between ecological ceilings and basic human needs.
• Calculating a country's impact requires a choice between production-based indicators (territorial) and consumption-based indicators (footprints), with the latter being essential for capturing impacts in global supply chains.
• Data availability is a primary obstacle to calculating national boundaries, often forcing researchers to choose indicators based on available data rather than ideal scientific metrics; many international MRIO databases require licenses or have outdated data.
• In Estonia, the planetary boundaries concept is currently used only as a general term in policy; there is no specific calculation of Estonia's 'own share' to provide a science-based foundation for decision-making.
• The report suggests that Estonia could start calculating its share by focusing on a few boundaries with better data, such as biodiversity, freshwater consumption, climate change, or land-use.
