Just like Fairtrade coffee and chocolate, the certification by the Aluminium Stewardship Initiative (ASI) gives the metal an ethical stamp of approval. It's assessed against strict, independently audited criteria including production, emissions, waste, biodiversity and human rights.
"Our promise to our consumers is that they’re going to have a sustainably produced, high-quality product," says Daniel Weston, general counsel and global head of Nespresso's Creating Shared Value group.
"You cannot have a sustainable proposition to your consumers if you are not implementing sustainability practices in your business.
"For us, this means everything from supporting our coffee farming communities to promoting the sustainable production and circular use of our aluminium packaging."
Aluminium ticks a lot of boxes. It's lightweight, strong, and importantly for Nespresso – infinitely recyclable.
"Aluminium plays a critical role for us – it helps us preserve the freshness and aromas of the coffees, and it also helps us meet our sustainability goals too.
"It can be taken back and recycled and put back into the upstream supply chain," Daniel says.
