ENVIRONMENTAL IMPACT
Your forecast error has a carbon cost
Why demand planning is the most overlooked lever in consumer goods ESG ratings
20-40%
Typical forecast error in
consumer goods
That's the share of production volume that was potentially unnecessary, along with all the energy, transport and materials it consumed.
Most ESG programmes
miss this entirely
Forecasting precision and the environmental case for better demand planning.
When a consumer goods business misses its demand forecast by 25%, production runs overshoot, inventory builds, stock gets transported, stored, offered on a discount and eventually destroyed when it can't be sold.
Every step in that sequence burns carbon.
Raw materials extracted.
Energy consumed in manufacturing.
Diesel burned in transit.
Electricity used in storage.
At the end, disposal or incineration.
All of it avoidable.
Most ESG programmes miss this entirely
Consumer goods businesses have invested heavily in the visible end of sustainability. Packaging redesign. Renewable energy commitments. Transport network reviews. Fleet upgrades.
These are real improvements. But they focus on the delivery of product, not the decision to make it.
Demand planning sits upstream of every manufacturing decision.
It rarely appears in an ESG report, a sustainability framework or a carbon reduction target.
The plan sets the volume.
The volume sets the emissions.
A forecast error of 20% means roughly 20% of production volume was potentially unnecessary.
That's 20% of manufacturing energy, 20% of raw material use, 20% of primary transport.
When that surplus stock can't be sold at full price, you add markdown logistics, secondary distribution and eventual write-off to the equation.
The carbon embedded in unsold stock doesn't appear on an energy bill. It's invisible in most ESG frameworks.
But it's real, and it adds up.

The commercial and environmental case are the
same
Less
stock
carried
Carry what you'll actually sell. Less holding means less embedded carbon.
Fewer emergency shipments
Reactive transport is expensive and carbon-heavy. Better plans mean fewer scrambles.
Less
written
off
Disposed inventory is wasted carbon. Reduce write-offs and the emissions that caused them.
Where most businesses carry the hidden waste
The waste doesn't show up in one place.
It accumulates across the supply chain, quietly.
By the time inventory reaches markdown, disposal or write-off, the carbon has already been spent.
You're looking at the commercial consequence of a decision made months earlier, in the demand plan.
Overproduction
Energy, water, materials consumed for units that won't sell.
Reactive transfers
Urgent depot-to-depot moves to correct imbalances caused by bad planning.
Third-party storage
Energy to run overflow storage hired to hold stock that shouldn't exist.
Disposal and write-off
Incineration, landfill or destruction.
The carbon has already been spent.
What MET does about it
MET works with consumer goods suppliers to reduce forecast error.
We look at demand signals, customer data, planning processes and the gap between what businesses plan and what actually sells.
Most clients start with a commercial problem: too much stock, working capital tied up, service failures.
The environmental outcome is part of the same work.
The improvement usually comes from clearer thinking about demand and honest measurement of what the current plan is actually getting right and wrong.
