Sourcing Risks
Identifying and scoring nature-related supply-chain risks: HICL and EUDR flags, and the commodity-country sourcing risk score.
Sourcing risks
Purpose
Starting from the commodity inventory, this module identifies nature-related risks embedded in a company's supply chain by flagging commodities with known high biodiversity impact potential.
Flagging approach
Two flags are applied to each commodity in the inventory:
HICL flag — SBTN High Impact Commodity List
Based on the SBTN HICL v1, a science-based reference list of 47 commodities identified as material drivers of nature loss across three socioeconomic systems:
- Food system: e.g. cattle, cocoa, soybean, oil palm, timber, sugarcane, aquaculture
- Energy and extractives: e.g. crude oil, coal, copper, gold, lithium, nickel
- Built environment: e.g. cement, sand
For each commodity, material pressures are documented across 9 pressure categories (from the SBTN literature review and ENCORE). The number displayed on the HICL flag indicates how many of these 9 categories are material for that commodity. The 9 categories are:
- Land use (terrestrial ecosystem use & use change)
- Freshwater ecosystem use & use change
- Marine ecosystem use & use change
- Water use
- Climate change
- Air pollution (non-GHG)
- Soil / terrestrial pollution
- Freshwater pollution
- Marine pollution
- Invasive alien species (one of the five IPBES pressures) is not covered by the HICL framework.
- The official SBTN HICL v1 lists Freshwater pollution as the only formal pollution sub-category; Darwin formalises Marine pollution as a distinct flag based on individual HICL commodity entries.
EUDR flag — EU Deforestation Regulation
Flags commodities subject to the EU Deforestation Regulation, which applies to cattle, cocoa, coffee, palm oil, soya, wood, rubber and their derived products. Companies placing these commodities on the EU market must demonstrate they are not linked to recent deforestation.
Examples
| Commodity | Type | HICL | EUDR | Material pressures |
|---|---|---|---|---|
| Dairy (from cattle) | Food system | Y (4) | Y | Water use, climate change, soil pollution, water pollution |
| Sugarcane | Food system | Y (5) | — | Land use change, water use, climate change, soil pollution, freshwater pollution |
| Copper | Energy & extractives | Y (6) | — | Land use change, resource overexploitation, water use, climate change, soil pollution, water pollution |
Sourcing Risk score
Beyond the flags, the module scores where a company's supply-chain nature risk concentrates. The unit of analysis is a commodity × sourcing-country pair (e.g. cocoa from Côte d'Ivoire).
The score is built in two distinct stages — selection (which drivers count) and scoring (how the selected drivers form the number). Keeping them apart matters: materiality only selects a driver, it does not weight the score.
Stage 1 — Selection: which drivers count
A risk driver (indicator) enters a pair only when it passes both gates:
-
Materiality gate — the driver is material for the commodity. This is a presence test (yes / no), satisfied by either source:
- flagged by ENCORE materiality — each commodity is mapped to an ENCORE economic activity, i.e. its sector (e.g. sawlog and veneer log → forestry), and inherits that activity's materiality ratings; the driver counts when the activity is scored ≥ 4 (High / Very High) for that indicator at Scope 1; or
- flagged by an SBTN HICL flag that maps to a scorable risk driver — 6 of the 9 HICL categories (land use, water use, air pollution, freshwater pollution, soil pollution, freshwater ecosystem use). Three categories are not mapped: climate/GHG and marine ecosystem use have no matching risk indicator at all, and marine pollution is deliberately left unmapped because the available pollution layers are terrestrial (air, pesticides, soil & water) and scoring marine pollution against them would be wrong. A commodity flagged only on those three gains no driver here.
The ENCORE materiality level beyond the ≥ 4 threshold is not carried forward — selection is pass/fail, not graded. Two cultural ecosystem services (spiritual & artistic, educational & scientific) never enter: they are off the ratified risk-driver list and have no wired layer. Recreation is a wired driver and is selected like any other.
-
Geography gate — the driver's own wired layer(s) are aggregated over the sourcing country (for a raster layer, an area-weighted mean of its values) and bucketed into a risk level — the worst level across a driver's layers when it has more than one; the driver is selected when that country-level risk is High or Very High. Each driver reads its own layer(s), not the worst level of its whole risk dimension — a dimension carries many drivers, so a per-dimension level would let one severe driver make the others read as severe too.
Both gates apply identically, whichever materiality source admitted the driver.
Stage 2 — Scoring: how the selected drivers form the number
Only drivers that passed both gates contribute, and an EUDR-regulated pair adds one fixed regulatory term:
score(pair) = Σ ( severity + HICL bonus ) over the selected drivers
+ EUDR term
severity from the GEOGRAPHY level: Very High = 2 · High = 1
HICL bonus +1 when the driver was admitted by BOTH ENCORE and HICL
(an agreement of two independent sources), else 0
EUDR term +3, once, when the pair's commodity falls under the EUDR, else 0
Two things follow from this:
- The severity weight comes from the geography level, not from the ENCORE materiality rating. Materiality selected the driver; the sourcing country's risk weights it. A driver barely material (ENCORE = 4) and one strongly material (ENCORE = 5) score the same if their country level is the same.
- The only materiality-derived term in the number is the HICL confirmation bonus. It rewards agreement between two independent sources — so it does not saturate the way a standalone HICL term would. The weights (Very High 2 / High 1 / HICL bonus 1 / EUDR 3) are a methodology-owned calibration.
EUDR is a score term, weighted as one driver at its worst
EUDR exposure is regulatory, not an environmental severity. It still sits in the numeric score, so the ranking reads on a single scale. It weighs 3 points, added once per regulated pair. That is the most a single driver can contribute (Very High, confirmed by HICL): a legal obligation to prove a deforestation-free supply chain gets as much attention as one driver at the top of its severity, and no more. Two Very High drivers still outrank a regulated pair from a risk-free country. The EUDR term never creates a score for an origin that cannot be scored (e.g. RoW, GLO). Among those unscored pairs, regulated ones are listed first.
Displayed risk level
A pair's displayed level is its worst country driver — Very High, else High, else no material risk. EUDR does not raise this level: regulatory exposure is surfaced as a separate ⚖ compliance chip, so an EUDR-only pair shows an empty risk badge while still ranking on the 3 points of its EUDR term.
From pairs to a commodity
A commodity's level and score are those of its worst pair (the maximum), so ranking commodities by risk reflects their most-exposed sourcing origin.
Risk family filter
Each country driver carries a risk family: Climate (a hazard whose loss the climate engine prices, e.g. water stress) or Nature (every other driver, whether a pressure on nature or a dependency no climate engine prices), read from the same driver catalogue as Sites & territories; see Risk family. Filtering on a family restricts the drivers before scoring, so a pair's score and displayed level are recomputed on that family alone. The EUDR term stays, since a pair is regulated whichever family is read. A pair with no driver in the selected family still counts as scored — assessed, with nothing in that family — which is not the same as unscorable. Grouping by risk family is an exposure view: a pair with drivers in both families counts under each, so the groups do not add up to the total.
Sorting
The rollup can be ordered by:
- Risk — the score, EUDR term included. Pairs that cannot be scored come last, with regulated ones first among them.
- Impact — the assessed environmental impact.
- Unit impact — impact ÷ quantity.
Unit impact is strictly comparable only within a single commodity: units differ across commodities (kg vs litres vs items), so a cross-commodity "Unit impact" ranking is indicative, not an exact comparison.
