Intro
This is the first in a series of seven posts we’re publishing over the coming weeks. Each one asks a simple question about how your ETRM handles emissions trading, and explores what good practice actually looks like. If you’re a trader, risk manager, or ops professional working in EU ETS, UK ETS, or voluntary carbon markets, these are the questions worth asking before your next system review.
Expiry is not the end of the story
Emissions allowances are operationally different from most other exchange-traded energy products, as they are physically settled instruments. When a futures contract expires, the trader doesn’t just cash-settle a difference, they end up owning certificates that land in a registry account. Those certificates then need to be tracked, valued, and managed until they are surrendered for compliance or sold onward.
In emissions, a futures position becomes a physical obligation
The problem is that many ETRM systems treat futures expiry as the end of the road. The position drops off the blotter and the P&L stops updating. From that point on, the operations team is left piecing together the picture in spreadsheets, manually booking the physical delivery, manually tracking what sits in the registry, and manually working out what the inventory is worth on any given day.
The trader then loses sight of their real exposure, the risk office can’t produce a complete P&L, and the back office is always playing catch-up.
You need one continuous view from futures to physical to inventory
What you want instead is a system that follows the position through all three stages of its lifecycle, futures, physical, and inventory, without the trail going cold at any transition point. That means an automated rollover process: when a futures contract hits its expiry date, the system identifies it, creates the corresponding physical trade automatically, and continues tracking the P&L. When that physical reaches its delivery date, a second automated process closes the physical leg and creates the inventory position.
The P&L thread should be continuous, in which the entry price from the original futures trade carries through into the physical valuation, and from there into the daily mark-to-market on the inventory holding. At any point, the trader can see what they paid, what the position is worth now, and how the market has moved since delivery.
If the system only shows one stage, you do not have the full picture
Why does this matter in practice? If we consider a straightforward scenario, in which you are short on a December futures contract, you need to know (now, not after a month-end reconciliation) how many allowances you hold in inventory, how many are due to arrive via physical delivery over the coming weeks, and whether the total is enough to cover your obligation. If it isn’t, you need to go into the OTC market and buy the shortfall. That decision depends entirely on having an accurate, unified view across futures, physicals, and inventory. If the system only shows you one of those three, you don’t have the information you need.
Next week, we’ll look at the second question: whether your system lets you see trading P&L and inventory P&L side-by-side, and why that distinction matters more than most people think.
