Computers since six. Oil fields, then wind and carbon.

Jason Faeq · Hamburg, Germany

I trained as a petroleum engineer and now work in sustainable design and procurement at Vattenfall while studying for an MSc in Environmental Engineering at TUHH. Hardware, software and maths have hooked me since childhood; now I use them for carbon accounting and LCA, data models and reporting, and automating the manual steps in between.

Sustainability

Emissions baselines and abatement-cost cases for onshore wind, embodied-carbon screening, and LCA models in Python.

Data

SharePoint data models, Power BI reports and SQL and Python analysis, from supplier commitments to SAP master data.

Automation

Power Automate, AI Builder and Azure runbooks turn supplier contracts into sustainability records for human review.

Tools for energy, procurement and climate data.

Carbon Takeoff

When lower-carbon steel costs more, spend-based accounting can report higher emissions.

Low-emission steel was one of the levers I led at Vattenfall. Here Claude extracts quantities with page citations, and a reviewer accepts each line before it counts.

LiveGitHub
More detail

AI-assisted embodied-carbon screening for procurement. Import a bill of materials, or let Claude read a specification and extract quantities with page-level evidence; a reviewer accepts each line, and accepted lines are matched to sourced emission factors. Out come the total, the hotspots, lower-carbon alternatives and a spend- vs activity-based comparison.

Highlights
  • Quantities traced back to the page and quoted text
  • Human review before anything is counted
  • Every emission factor carries its source
  • Spend vs activity: switch steel to the EAF route and watch the two methods disagree
Built with
  • Next.js
  • TypeScript
  • Claude API
  • Tailwind CSS
  • Vitest

Screening-level cradle-to-gate estimate (A1–A3), not an EN 15978 or ISO 14040/44 LCA. All demo data is synthetic.

Vattenflow

Structured requests for SAP master data changes, turned into the Service Desk's Excel templates.

Requesters submit one record or many through validated forms; an admin reviews each request, and its status history stays with it.

LiveGitHub
More detail

A workflow app for WBS and cost centre change requests in SAP master data. Requesters fill in structured, validated forms for one record or many; admins review them, and every request keeps its status and history.

Highlights
  • Role-based requester and admin portals
  • Multi-record forms with field validation
  • Request history and analytics
Built with
  • React
  • Next.js
  • Firebase Auth
  • Firestore
  • FastAPI

Dynamic resource scarcity in LCA

Scarcity factors for LCA that follow extraction, ore grades and recycling over time.

So far I've reproduced ReCiPe's published copper and lithium factors in Python/SciPy; the time-dependent model is in progress.

Illustrative curve shapes, not results

In progress · 12 ECTS · delivery Feb 2027

More detail

Extending the ReCiPe 2016 mineral and fossil scarcity midpoints into time-dependent characterisation factors, driven by cumulative extraction, ore-grade decline and primary demand net of recycling. Reproduced ReCiPe's published copper and lithium factors in a Python/SciPy model; now designing the integration with time-explicit LCA in bw_timex.
