Factors Considered in LCA
Energy Consumption
Total energy required across all stages, including renewable and non-renewable sources. Higher energy use typically means more greenhouse gas emissions.
Carbon Footprint
Total greenhouse gas emissions (CO₂, methane, nitrous oxide) expressed as CO₂ equivalent. This has a direct link to climate change impact.
Water Use and Pollution
Water consumption and contamination at each stage. Critical for water-scarce regions and aquatic ecosystems.
Toxicity and Chemical Impact
Release of harmful chemicals to air, water, and soil. This affects human health and ecosystem safety.
Land Use and Biodiversity
Land area required and impact on natural habitats. Habitat loss is a major driver of biodiversity decline.
Waste Generation
Total waste produced including hazardous and non-hazardous materials. This links to resource depletion and pollution.
