Sustainability Assessment Forge

Use this skill when a project needs a credible sustainability assessment rather than a headline performance summary.

Core Principle

Sustainability claims only become comparable after the study defines a fair functional unit, clear system boundary, defensible inventory basis, transparent economic assumptions, explicit uncertainty treatment, and realistic scale-up path.

Intake

Identify:

technology or process type;
claimed product, service, or environmental function;
target question: LCA, TEA, or combined LCA plus TEA;
functional unit and reference flow;
comparator or baseline pathway;
system boundary;
scale and technology-readiness stage;
feedstock type, moisture basis, availability pattern, and logistics assumptions, if an agricultural or bioprocess system is in scope;
energy, electricity, heat, and feedstock assumptions;
coproduct handling rule;
target cost metric or environmental metric;
uncertainty target;
scenario target;
scale-up claim;
intended manuscript or decision claim.

Load:

references/lca-boundary-and-functional-unit.md for goal, scope, boundary, functional unit, allocation, and comparability checks.
references/tea-cost-driver-and-scale-up.md for CAPEX, OPEX, throughput, utilization, cost metrics, and scale-up realism.
references/uncertainty-scenario-and-scale-up.md for sensitivity, uncertainty, scenario framing, and interpretation limits.
references/agri-bio-process-audit.md for agricultural residues, biomass conversion, biofuels, bioproducts, waste-to-value, nutrient loops, logistics, seasonality, and coproduct-heavy systems.
references/spatial-manure-nutrient-optimization.md for manure management, nutrient recovery, spatial optimization, externality internalization, societal costs, GAMS models, and Zenodo-based reproducibility audits.
references/anaerobic-digestion-microbiome-metabolome.md for anaerobic digestion, full-scale digesters, microbiome-metabolome coupling, DOM molecular profiling, methane-performance linkage, and monitoring or optimization interpretation.
references/electrochemical-systems-audit.md for electrochemical systems and other energy-intensive process papers.
references/policy-portfolio-and-safe-boundary.md for safe-boundary framing, multi-sector reduction targets, policy portfolios, co-benefit translation, and cross-domain environmental burden planning.

Use:

templates/lca-tea-audit.md for a structured audit memo;
templates/lca-tea-extraction-schema.csv for study extraction;
templates/agri-bio-process-audit.md and templates/agri-bio-process-schema.csv for biomass, residue, biorefinery, manure, digestate, biochar, waste-stream, and agriculture-linked process systems;
templates/spatial-nutrient-optimization-reproducibility-audit.md for spatial manure/nutrient recovery papers with public figure data, model inputs, plotting code, and partial or full optimization reproducibility;
templates/anaerobic-digestion-systems-audit.md for microbiome-metabolome and performance-coupled anaerobic digestion studies;
templates/scenario-sensitivity-matrix.csv for baseline and alternative cases;
templates/policy-portfolio-scenario-schema.csv for policy-target, sector, technology, and structural-measure comparisons;
templates/scale-up-readiness-checklist.md for lab-to-pilot-to-commercial translation.

Workflow

Define the claimed function of the system.
Freeze the functional unit and reference flow.
Draw the system boundary and note exclusions.
Check whether the comparator is fair.
Record material, energy, electricity, and transport assumptions.
Check coproduct treatment and allocation or substitution logic.
Build the TEA basis: capacity, utilization, CAPEX, OPEX, lifetime, financing assumptions, and cost metric.
Separate measured values from assumed values.
For agricultural or bioprocess systems, make feedstock moisture, transport radius, seasonality, coproduct use, and nutrient-return logic explicit.
Identify the dominant environmental and economic drivers.
Build scenario and sensitivity cases.
Review scale-up realism and deployment bottlenecks.
If the paper makes policy-facing claims, separate single measures from portfolio logic and safe-boundary logic.
Write an interpretation that matches what the model can actually support.

Guardrails

Do not compare systems on different functional units without saying so explicitly.
Do not treat a narrow boundary as a full sustainability verdict.
Do not repeat TEA outputs without the cost basis and utilization assumptions.
Do not let a best-case electricity mix masquerade as a default case.
Do not treat a single sensitivity tornado as full uncertainty analysis.
Do not infer commercial viability from high selectivity or current density alone.
Do not let policy-portfolio language hide the underlying sector and assumption structure.
Do not treat residue feedstocks as free, uniform, and always available without discussing collection, moisture, contamination, and competing uses.
Do not treat coproduct credits or fertilizer substitution as automatic without a transparent counterfactual.
Do not convert lab performance into industrial conclusions without discussing separations, durability, uptime, and balance-of-plant requirements.
Do not call a spatial optimization paper fully reproducible when only figure data, model inputs, or plotting code are public and the executable optimization model is missing.
