Limitations and Challenges of LCA

📋 Limitations and Challenges of LCA

Incomplete or Poor Quality Data

Many stages lack accurate data, requiring estimates and assumptions. For example, supply chain impacts in developing countries are often poorly documented.

Subjective Value Judgments

It's difficult to compare different types of environmental impact. How do you compare CO₂ emissions vs biodiversity loss vs water pollution?

Boundary Definition Problems

It's unclear what to include or exclude from the assessment. Should worker commuting be included? Factory construction? Indirect land use?

Commercial Bias and Greenwashing

Companies may manipulate results to favor their products by cherry-picking data, excluding unfavorable stages, or using favorable assumptions.

Temporal and Geographical Variations

Impacts vary by location and time. For example, electricity grid emissions vary by country and are changing as renewable energy increases.
