Define Sustainability Scope and Select Assessment Framework
1–2 weeks (2–3 hrs/week)
Select a real or realistic engineering design subject: a building, product, infrastructure element, or manufacturing process. Define the sustainability assessment scope: what system boundary will be assessed (cradle-to-gate, cradle-to-grave, or gate-to-gate), which sustainability dimensions will be covered (environmental, social, economic — triple bottom line), and which assessment framework will be used (Life Cycle Assessment per ISO 14040/44, BREEAM, LEED, GRI, or equivalent). Document the rationale for the scope and framework choice, including what is excluded from scope and why. Sustainability assessments without clear scope boundaries produce results that cannot be interpreted or compared.
Proof required
Submit your scope definition document (≥500 words): the design subject described, the system boundary defined (what's in scope and what's excluded and why), the assessment framework selected with justification, and the sustainability dimensions to be evaluated.
What gets checked
- System boundary is explicit — what is included and excluded in the assessment scope
- Assessment framework is named specifically (ISO 14040, BREEAM, LEED, GRI, or equivalent) — not 'a sustainability framework'
- Exclusions from scope are justified — not just stated
Common mistakes
- Scope defined as 'assess the sustainability of X' without specifying the system boundary — where does the system start and end? Material extraction? End of life? The answer changes the results significantly
- Framework selection without justification — ISO LCA is very different from BREEAM; the choice must be argued from the design subject and assessment purpose

What a verifier looks for
- Confirm system boundary is explicit — what is included and excluded, with justification for exclusions.
- Confirm assessment framework is named specifically — flag vague framework descriptions.
- Confirm sustainability dimensions are stated — at least environmental dimension is required.
Collect Data and Calculate Sustainability Indicators
3–4 weeks (4–5 hrs/week)
Collect quantitative data for the sustainability assessment within the defined scope. For an LCA: collect material quantities, process energy inputs, and transport distances; use an environmental database (ecoinvent free datasets, EPA LCA Commons, or OpenLCA) to estimate greenhouse gas emissions, energy use, and key impact categories. For a BREEAM or LEED assessment: calculate the achieved credits against the relevant categories (energy, materials, transport, waste, ecology). Produce a summary table of sustainability indicators with values, units, and data sources cited for each indicator.
Proof required
Submit your sustainability data table (≥6 indicators with values, units, and data source cited for each) and the calculation method used for each indicator (or credit achievement rationale for BREEAM/LEED).
What gets checked
- ≥6 sustainability indicators are quantified with values and units — not stated as 'assessed qualitatively'
- Each indicator cites its data source — ecoinvent, EPA LCA Commons, manufacturer EPD, or equivalent
- Data is collected within the defined scope from M1 — not expanded to cover a different boundary
Common mistakes
- Qualitative sustainability assessment without quantification — 'the design uses sustainable materials' is not a sustainability indicator; '12.4 kgCO2e per m² of concrete from ecoinvent 3.8 at supplier gate' is
- Data collected outside the defined scope boundary from M1 — if M1 defined cradle-to-gate scope, end-of-life data must not be included; consistency with scope is a quality criterion

What a verifier looks for
- Confirm ≥6 sustainability indicators are quantified with values and units — flag qualitative-only assessments.
- Confirm each indicator cites its data source by name.
- Confirm data is collected within the M1 scope boundary — flag indicators that breach the defined boundary.
Write the Sustainability Assessment Report and Propose Improvements
2–3 weeks (2–3 hrs/week)
Write a complete sustainability assessment report (2,000–3,000 words plus data tables) covering: assessment scope and framework, data and methodology, sustainability indicator results, comparison against a baseline or benchmark (similar design, industry average, or code minimum), identification of the highest-impact hotspots, and ≥3 specific design improvement recommendations with estimated impact reduction. Have the report reviewed by an engineer with sustainability experience and respond to Q&A on the methodology and recommendations.
Proof required
Submit your sustainability assessment report (2,000–3,000 words plus data tables) and review record: reviewer name, role, ≥3 challenge questions about methodology or recommendations, and your responses.
What gets checked
- Results are compared against a baseline or benchmark — not reported as absolute values without context
- ≥3 improvement recommendations are specific and quantified — 'switch to recycled steel' is not specific enough; 'switching from virgin steel to recycled content steel reduces embodied carbon by approximately 40% based on EPD data for this material' is
- Reviewer has sustainability, LCA, or environmental engineering experience
Common mistakes
- Recommendations without quantified impact — 'use more sustainable materials' is not an engineering recommendation; the improvement must be quantifiable against the indicators already calculated
- No baseline or benchmark comparison — sustainability assessment results are meaningless without context; compare against the previous design version, a code minimum, an industry average, or a certified benchmark

What a verifier looks for
- Engineering Design Triad check: M1–M3 together produce a design artifact (assessment scope + improvement recommendations), an analysis artifact (sustainability indicator calculations + hotspot identification), and a documentation artifact (sustainability assessment report + review record) — confirm all three types are present.
- Confirm results are compared against a named baseline or benchmark.
- Confirm ≥3 improvement recommendations are quantified — flag unquantified suggestions.
- Confirm reviewer has sustainability, LCA, or environmental engineering experience.
- The Proof Accessibility Rule applies — openLCA (free), EPA LCA Commons (free), ecoinvent free starter data, EU JRC free resources, BREEAM free standard download, and Circular Ecology free data are all accessible without commercial licence.
