Emission graph

How every emission gets its number

Every activity in your inventory links to the most specific LCA available: supplier, product, or process. When no factor exists, Bardo builds one, documented and ready for audit. Your footprint becomes evidence, not assumption.

What it does

Bardo’s Emission Graph continuously sources, verifies, and improves the emission factors that determine your footprint. It connects every activity in the Carbon Footprint Inventory to a traceable, ranked emission factor, giving you numbers you can trust, and defend

Our point of view

Sources and ranking, explained simply

We rank candidates by how closely they match the actual activity, then by quality and recency.

Rank	Factor type	Typical source	Why it matters
1	Supplier or product specific (verified or primary)	Supplier LCAs, verified product disclosures, or CDP/PEF data	Reflects what your company actually buys and from whom. These factors provide the strongest link between procurement and emissions, but only when the supplier data meets verification and transparency thresholds. Bardo evaluates every supplier LCA for methodological rigor, boundary coverage, and documentation quality. Verified or well-documented supplier LCAs form the gold standard; unverified or incomplete ones are downgraded.
2	Constructed or generated LCA (evidence-based)	Built by Bardo from public bills of materials, academic LCAs, or comparable process datasets	When supplier data is missing or unreliable, Bardo constructs an evidence-based LCA from verifiable sources. Each step, boundary, and assumption is documented and reviewed, providing transparency that often surpasses unverified supplier LCAs. Generated LCAs are ranked dynamically and upgraded when supplier data improves, ensuring completeness without compromising accuracy.
3	Product or process level	Public LCAs, Environmental Product Declarations (EPDs), process LCIs	Representative for similar products or services and useful when specific supplier or product data is unavailable. These sources give reasonable accuracy but miss technology and energy mix variations between suppliers. Bardo tracks their representativeness and prioritizes upgrades when more specific data emerges.
4	Regional or sector average	Databases such as Ecoinvent, DEFRA, Exiobase, or ADEME	Ensures coverage when higher-quality data isn't available. These averages smooth over critical differences in technology, region, and supply chain, leading to inflated or misleading results. Bardo uses them only temporarily and marks them for replacement, maintaining completeness while signaling improvement opportunities.
5	Placeholder (temporary)	Spend-based or global estimate	Used strictly to avoid data gaps. These placeholders maintain structural integrity in reporting but carry low confidence and are clearly labeled as temporary. Each placeholder is tracked through the system, ensuring it's replaced once better evidence becomes available.

When a factor is missing

We generate a documented LCA that is good enough to file and easy to replace.

Define scope and boundaries

Build the process from closest high quality inputs

Add energy mix, transport, and bill of materials where relevant

Record sources, assumptions, and reviewer notes

Assign uncertainty and an upgrade path to a target supplier or product LCA
