LCA Introduction/LCA Guideline

LCA vs CO₂e Explained

Most impact discussions focus on CO₂e, but quick carbon estimates often rely on weak data and risk 'carbon tunnel vision.' Learn why looking beyond CO₂e gives a clearer sustainability picture.

CO2e assessment

Common starting point to size impact. Frequently relies on suboptimal data, such as spend data and carries a risk of carbon tunnel vision.

LCA assessment

Provides a more holistic view by analyzing impacts across multiple indicators, including effects on human health, the natural environment, and climate.

Carbon tunnel vision in life cycle assessment, showing how focusing only on carbon emissions overlooks sustainability impacts such as biodiversity loss, water crisis, health, and inequality.

👉 Carbon tunnel vision: focusing only on CO2e can miss other material impacts, such as biodiversity, water, health, and social inequality.

Benefits of Full LCA Over CO₂e

  • Multi‑indicator view across human health, nature, and resource availability (not just climate)
  • Higher data quality, combining primary data with reputable LCA databases
  • Fair comparisons using a functional unit (impact per use, not per item)
  • Operational insight: clear hotspots in materials, processes, logistics, energy, and end‑of‑life
  • Credibility for declarations and public claims aligned with standards

Practical insight

Reducing material waste by even a few percentage points in manufacturing can lead to significant gains in:

  • Operational efficiency – less scrap, smoother workflows
  • Cost savings – lower input costs and waste management expenses
  • Environmental impact – reduced resource depletion and emissions

Small design or process changes—guided by LCA—can unlock measurable improvements across sustainability and profitability.
