Why We're Betting on Avoided Emissions — Not Just What We Produce

I walked past our zinc stacks last week and thought: we're counting the wrong emissions.

For years, the story was always Scopes 1, 2, 3. What we directly emit, what we buy in as energy, what happens downstream. Straightforward. Quantifiable. Boring, if I'm honest.

But waste experts and recyclers are moving the conversation sideways now.

They're looking at Scope 4 — what the industry calls "avoided emissions." The idea is simple enough: if your recycled zinc replaces virgin zinc from the earth, you're not just processing metal. You're preventing emissions that would have happened anyway. Mining, smelting, transport, all that energy and carbon that simply doesn't occur.

The numbers are not small. Recycled metals save enormous amounts of energy compared to primary production. We know this already, more or less. But the accounting frameworks are only now catching up. Companies are realising they can measure and claim credit for emissions that never entered the atmosphere because of decisions they made.

It's not magical accounting, actually, that's not quite right — it's an old environmental principle dressed in new language. The "avoided burden approach" in lifecycle assessment has existed for years. What's changed is that boardrooms suddenly care about it.

Why? Because ESG scores matter now. Investment decisions, insurance premiums, contract awards — they all hinge on whether you can prove environmental impact. And Scope 4 lets you tell a different story. Not "we polluted less than we could have," but "we actively prevented harm from happening elsewhere."

For a metals trader, this is significant. Zinc from scrap avoids the mining and smelting cycle. Every tonne diverted from landfill and returned to manufacturing represents energy not burned, ore not extracted, carbon not released.

The shift is real enough that major recyclers and waste companies are building their strategies around it.

But here's the thing — and this matters — Scope 4 is not a free pass. Waste experts are careful about this. Avoided emissions should not let you ignore actual emissions you produce. The two exist in tension. You still need to reduce your direct footprint. You can't just announce Scope 4 credits and call yourself clean.

The framework is emerging as a way to value what we do in the metals cycle, though. The positive externality becomes quantifiable. It enters the scorecard alongside everything else.

This means recyclers and scrap operators are no longer just disposal specialists or secondary suppliers. They're emissions reducers. It changes how business gets valued, how contracts get priced, who customers want to work with.

For Siam Sukkhee and companies like us, the message is straightforward: the metals we recover are not just products. They're carbon prevented.
