Recycling Is Climate Infrastructure: Why Metals Recycling Avoids More Carbon Than Most Forest Offsets

This article argues that industrial recycling, especially metals, should be treated as core climate infrastructure. It notes that steel recycling avoids roughly 950 million tonnes of CO2 annually, and metals recycling avoids 0.6 to 1.0 gigatonnes of CO2-equivalent per year. That is far more than the 68 million tonnes of forestry and land-use credits retired in the voluntary carbon market in 2024, and it is based on weighed material flows rather than modeled baselines. The author proposes circularity credits that track recovered material quantity, grade, chain of custody, and avoided emissions against a virgin-material baseline. This would let buyers of recycled steel, aluminum, and copper demonstrate displacement of primary production. The article also criticizes carbon offset additionality rules for rewarding hypothetical projects over operational ones. A useful read for anyone tracking carbon markets, CBAM, or low-carbon materials.

The comparison to forest credits is the useful part. Metals recycling avoids a measured tonnage of emissions through material substitution, while many offset projects lean on modeled baselines. That is a real difference in verifiability. The article would be stronger if it showed how circularity credits avoid double counting with existing scrap market incentives.

Steel recycling avoiding around 950 million tonnes a year is a big number. Worth noting that scrap supply is limited by how much steel exists in use, so recycling complements primary production rather than replacing all of it. Still, the argument that we undercount this in climate finance holds.

Aluminum is the case to watch. Smelting is electricity-heavy, so recycled aluminum displaces a lot of power demand. But the avoided emissions depend on the grid mix at the smelter. A circularity credit needs a clear baseline or it becomes another accounting debate.

The piece is right about additionality being backwards. A company with mature collection infrastructure is penalized because it already works. But circularity credits need standardized methodologies or they will repeat the same credibility problems as offsets. CBAM linkage is promising but not simple.

From a materials perspective, the point about chain of custody is underrated. Weighbridges, grades, yields, those are already audited in scrap markets. That data can feed carbon accounting without inventing new systems. The gap is getting buyers to pay for the avoided emissions.
