The Lab

The method in plain sight. No fluff, just data.

Environmental consulting hides its work behind reports nobody reads and "confidential clients". Here we do the opposite: our own projects, published, so you can see how a real analysis is done before you commission one.

Season 1 · Six cases

One case per sector. One question per case.

Six cases spanning different sectors and methods (LCA, water footprint, EPD and Digital Product Passport, social analysis), each with a real question and a decision backed by a number, not an "it depends".

PET, glass and aluminium drink bottles on a light background 01 · Container · Packaging Published

Glass sounds eco. Making it emits almost three times as much as plastic.

A comparative LCA of the same soft drink in a PET bottle, a glass bottle and an aluminium can. And the twist: the very same glass, reused, goes from worst to best of all.

Pine wood table, furniture detail 02 · Furniture · Wood Published

Renewable is not the same as low-carbon.

Cradle-to-grave LCA of a pine table, solid wood versus board (particleboard and MDF). Wood has its small print too: processing, toxics and durability.

Folded cotton T-shirt, textile product 03 · Textiles · EPD + DPP Published

Your recycled T-shirt doesn't cut carbon. It cuts something else.

Field-to-incinerator LCA of a T-shirt (virgin cotton, recycled cotton and recycled polyester), geared towards an EPD and the Digital Product Passport. Recycling barely touches the climate, but cuts land use by up to 79%. And rPET wins on footprint… which is exactly where the catch lies.

Almonds held in a hand, almond cultivation 04 · Food · Water Published

Same almond, different thirst. With water, the metric is the message.

Water footprint (litres) versus scarcity-weighted water footprint (AWARE) for the same almond from three origins. Changing the method changes the winner: local irrigated crops can weigh more than imported ones.

Product from the value chain analysed 05 · Value chain · Social Published

The social analysis hardly anyone does (because the tool is paid).

A dataset of social indicators built by hand from public standards and data to carry out S-LCA without paid databases, tested on a coffee from four origins. It completes the triad: environmental, economic and social.

Car on a road, battery and break-even analysis 06 · Mobility · Batteries Coming soon

An electric car pollutes more… up to how many kilometres?

LCA of a battery and its break-even point against a combustion car, with an eye on the Battery Passport the EU requires from 2027.

In preparation
Professional experience

A simulator that cut scenario calculation time by 87%

Packaging · Role: Sustainability analyst

Deliberately kept apart from the demonstration cases: this work came from a real assignment, anonymised for confidentiality. For a multinational packaging company, a decarbonisation pathway simulator that brought per-scenario analysis down from 4 h to 0.5 h, across 10 SKUs, under the GHG Protocol and ISO 14064.

The next step

What if these were the real data for your product?

The Lab cases use public data. Your product deserves its own: primary, verifiable, ready for your major customer or your tender. That's where the real work begins.
