Learn why looking beyond CO₂e gives a clearer sustainability picture. Common starting point to size impact. Frequently relies on suboptimal data, such as spend data and carries a risk of carbon tunnel vision. 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 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. | **Feature** | **CO₂e Assessment** | **Life Cycle Assessment (LCA)** | | :----------: | :-----------------: | :------------------------------------------: | | Scope | GHG emissions only | Multi-indicator (health, biodiversity, etc.) | | Data quality | Often spend-based | Combines primary + database | | Use case | Quick footprint | Detailed product analysis | ## 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. 👉 [Explore how Sustainly helps teams model material efficiency.](https://learn.sustainly.ai/4.Tutorials/3.simple-example) ## Where LCA drives decisions * Procurement * R\&D * Marketing * Sales Plan your full LCA through **Sustainly** and get results you can stand behind.🌱 [See how Sustainly works →](/https://sustainly.ai)
