A new life-cycle assessment has revealed environmental improvements in barista oat milk that even took Oatly by surprise, with exciting progress in land use and water efficiency, too
Oatly’s ambient barista oat drink now boasts a 67 per cent lower climate impact than chilled British cow’s milk, widening the footprint gap from 58 per cent recorded in 2021.
The increase was confirmed by an independent life-cycle analysis (LCA) conducted by Mérieux NutriSciences | Blonk. Compared with its first review, published in 2022, its 2026 analysis showed that operational adjustments have yielded substantial environmental gains for Oatly.
In a statement shared on LinkedIn, Caroline Reid, Senior Sustainability Director at Oatly, called the increase “quite a jump,” emphasising that the numbers achieved were unexpected, even knowing the decisive actions the brand had taken.
“I was surprised,” she said, before explaining more of the story behind the figures.
How Oatly slashed oat milk emissions
The Swedish plant milk pioneer achieved its significant emissions improvements through its use of oats.
In late 2025, Oatly transitioned eight of its top-selling UK barista products to 100 per cent British oats. This supply chain switch was intended to reduce raw material distribution distances and cut the product’s footprint by between 7 and 13 per cent across key markets including the UK, Germany, and the Netherlands.
But the environmental advantages of Oatly’s strategy extend beyond greenhouse gases, also seeing reduced energy and water consumption across its production facilities.
Figures published in the LCA showed that in the UK, Oatly’s ambient barista drink widened the gap in land use from 19 per cent to 48 per cent compared to dairy. Meanwhile, the same product’s water use soared from a 16 per cent gap to being a massive 65 per cent more efficient than cow’s milk.
Oatly’s chilled oat milk products saw similar success, with comparable leaps in figures in the UK, Germany, and the Netherlands.

Why the dairy emissions gap continues to grow
Oatly can’t necessarily take full credit for the widening emissions gap, though its increased efficiency is a major factor. Updates to agricultural modelling standards (specifically the International Dairy Federation’s biophysical allocation framework) now attribute a larger share of environmental impact directly to milk production over meat.
Additionally, modern greenhouse gas calculations place greater weight on methane, a short-lived gas with high warming potential.
However, Oatly’s continued efforts to pioneer planet-friendly products can’t be denied. Continuing her LinkedIn post, Reid highlighted the importance of plant-based products to make environmental improvements for both consumers and organisations.
For consumers, she stated that it’s as simple as “swapping cow’s milk to Oatly in your morning latte,” while for the food industry, she expressed hope that businesses would increasingly “raise their voices asking for policies and food environments that support planetary health diets.”
She signed off with a final plea: “Can we please see more delicious plant-rich foods drop the ‘alternative’ cape to become the new norms and heroes of everyday eating?”
