• Climate change
Impact caused by greenhouse gas emissions (such as CO₂, CH₄, or N₂O) that contribute to global warming and alterations in global climate patterns.
• Ozone depletion
Effect of emissions of substances (e.g., CFCs or halons) that destroy the stratospheric ozone layer, increasing ultraviolet radiation reaching the Earth’s surface.
• Photochemical ozone formation
Formation of tropospheric ozone (“smog”) due to reactions between volatile organic compounds and nitrogen oxides under sunlight, affecting air quality and human health.
• Acidification
Emission of gases like SO₂, NOₓ, or NH₃ that transform into acids in the atmosphere, leading to acid rain and degradation of soils, forests, and aquatic ecosystems.
• Particulate matter formation
Release of fine particles (PM₂.₅ and PM₁₀) that remain suspended in the air, deteriorating air quality and contributing to respiratory and cardiovascular diseases.
• Eutrophication: freshwater
Excess input of nutrients, mainly phosphorus, into rivers and lakes, causing algal blooms, oxygen depletion, and ecosystem imbalance.
• Eutrophication: marine
Excess nitrogen in marine or coastal environments, leading to uncontrolled algal growth and loss of marine biodiversity.
• Eutrophication: terrestrial
Excess nitrogen deposition in terrestrial ecosystems, altering plant composition and reducing biodiversity.
• Ecotoxicity: freshwater
Toxic effects of chemical substances on aquatic organisms, impairing their survival, growth, or reproduction.
• Human toxicity: carcinogenic
Potential of certain chemicals or emissions to cause cancer in humans throughout the product life cycle.
• Human toxicity: non-carcinogenic
Adverse effects on human health (neurological, respiratory, endocrine, etc.) caused by exposure to non-carcinogenic substances.
• Ionising radiation: human health
Impact on human health due to exposure to ionising radiation from nuclear processes or electricity generation.
• Land use
Occupation, transformation, or degradation of land by human activities (agriculture, livestock, urbanization), affecting soil fertility and biodiversity.
• Water use
Consumption of water resources considering regional scarcity, competition among users, and ecological impacts.
• Energy resources: non-renewable, fossil
Consumption of fossil fuels such as oil, gas, or coal, leading to depletion of finite resources and emissions from their extraction and use.
• Material resources: metals/minerals
Extraction of metals and minerals from the Earth’s crust, considering limited availability and environmental impacts of mining activities.
