The costly decisions nobody revisited.

I’m Jessica Moon. I help organizations create and protect value in waste, energy, and materials, by finding the hidden costs in everyday operations and redesigning how the work gets done.

Sustainable Journey Labs is my independent advisory practice. You work with me directly.

Hidden costs come from old decisions no one has reviewed.

I call that build-up Governance Debt. It shows up as thinner margins, regulatory risk, and worn-out assets. So I start with one question: what can we stop doing?

I focus on three areas where this debt hides most: waste, energy, and materials.

01

Rules that changed.

New regulations make old processes costly.

EPR and packaging rules Idling rules Emissions reporting
02

Decisions nobody revisited.

Specs, policies, and contracts set once and never reviewed.

Product specs Overrun policies Fleet practices Vendor contracts
03

Transitions in motion.

Changes already underway, where getting the sequence right protects the investment.

Acquisitions and integration Fleet electrification Energy upgrades AI adoption

A solo practice, by design.

When you hire Sustainable Journey Labs, you get me, from the first call through implementation.

I spent 20+ years at Scholastic, most recently as Senior Director of ESG & Sustainability. There I built the company’s first ESG function and consolidated a global compliance function, which cut its overhead by 85%. I use the same method now: discover, design, build, enable.

I’ve been the person inside the company who had to make the change work, not just the advisor recommending it.

If a project needs deep technical specialty, I bring in trusted specialists, and I stay accountable for the work.

How I work

Every engagement is built to create and protect value, with operational excellence and sustainability in mind from the start. Most clients start with step one.

01

Discover

I find the gaps between your commitments and your operations, and I put a dollar figure on each. I use AI to move faster through contracts, specs, and data. Available as a deal screen, a post-acquisition integration review, or an exit-readiness check.

02

Design

We decide what to stop, what to fix, and in what order.

03

Build

I put new processes, tools, and monitoring in place, with automation where it actually saves time.

04

Enable

I work with your operations, finance, and legal teams until the change holds.

What I find

Two examples of hidden costs, measured.

Case Study 01

Car-free streets, idling trucks.

DSNY trucks idled continuously during Car-Free Earth Day and the Five Boro Bike Tour, with operators citing “Clean Idle” certification as permission to idle. It isn’t permission.

~800 gal diesel
~$4,750 avoidable fuel cost
~9 tons CO₂
~24,000 engine-wear miles

Where it shows up: fuel and maintenance costs on the P&L; shorter engine life on the balance sheet.

The Fix

Close the compliance gap, add oversight, and use APUs or battery-electric support.

Case Study 02

The spec nobody reviewed.

A quarter-inch design choice can add tons of waste and thousands in cost. In publishing, waste builds up at three points: the spec, the press run, and end-of-life handling.

12–18% of paper never reaches a reader
$0.08–$0.14 per unit avoidable cost
15–25% lower paper emissions with no product redesign

Where it shows up: paper and printing costs on the P&L; excess inventory on the balance sheet.

The Fix

A production spec audit, basis-weight optimization, and demand-signal integration.

Curious what I’d find?

The best next step is a 30-minute call.
