The nine planetary boundaries
1. Climate Change
1. Climate Change
The increase in greenhouse gas emissions from human activities is raising global temperatures, leading to extreme weather events, sea level rise, and disruption of ecosystems that support human life.
2. Biosphere Integrity
2. Biosphere Integrity
The loss of biodiversity and degradation of ecosystems are eroding the planet’s capacity to support life and maintain critical ecological functions, including pollination, water filtration, and carbon storage.
3. Stratospheric Ozone Depletion
3. Stratospheric Ozone Depletion
The release of substances such as chlorofluorocarbons (CFCs) has depleted the ozone layer, allowing harmful ultraviolet radiation to reach the Earth’s surface and damage living organisms.
4. Ocean Acidification
4. Ocean Acidification
As oceans absorb excess CO₂ from the atmosphere, their pH decreases. This acidification harms marine organisms — particularly those with calcium carbonate shells or skeletons — and disrupts marine food webs.
5. Biogeochemical Flows
5. Biogeochemical Flows
Excessive use of fertilisers and the release of industrial pollutants are disrupting the nitrogen and phosphorus cycles. These disruptions affect ecosystem health, biodiversity, and water quality at a global scale.
6. Land-System Change
6. Land-System Change
The conversion of natural habitats — forests, wetlands, grasslands — for agriculture, urbanisation, and resource extraction is a leading driver of biodiversity loss, soil degradation, and increased greenhouse gas emissions.
7. Freshwater Use
7. Freshwater Use
Unsustainable extraction and management of freshwater resources is causing water scarcity in many regions, as well as broader ecosystem degradation where river flows, lakes, and groundwater are depleted beyond natural replenishment rates.
8. Atmospheric Aerosol Loading
8. Atmospheric Aerosol Loading
The release of particulate matter and other aerosol pollutants into the atmosphere influences regional climate patterns, reduces air quality, and has well-documented negative effects on human health.
9. Novel Entities
9. Novel Entities
The introduction of synthetic chemicals, plastics, pharmaceutical residues, and other novel substances into the environment creates risks that are difficult to quantify because the long-term effects on ecosystems and human health remain poorly understood.
Current status
The six boundaries currently exceeded are: Climate Change, Biosphere Integrity, Biogeochemical Flows, Land-System Change, Freshwater Use, and Novel Entities.Why planetary boundaries matter for LCA
LCA, and PEF in particular, measures impact across 16 environmental impact categories — many of which map directly onto planetary boundaries. When you calculate a product footprint in Målbar, you are measuring contribution to several of these global limits, not just climate change.A PEF single score aggregates all 16 impact categories into one number. This provides a more complete view of a product’s environmental burden — including impacts on water, land, and ecosystems — alongside the climate impact measured in CO₂eq.
Målbar’s commitment to current data
Målbar monitors updates from the Stockholm Resilience Centre and the Potsdam Institute and updates the underlying data and context in this documentation as new assessments are published.Download the illustration
