It's a story of triumph over adversity – or at very least decidedly unpromising beginnings. Setting itself a 10 per cent target three years ago, it only managed 0.4 per cent in 2014, but managed to turn things around. It is now focusing on increasing the amount of renewables in its energy mix.
We're talking some serious investment here, with the company putting money into the expansion of the Burbo Bank wind farm off the Merseyside coast, to increase generating capacity by 250MW. It also owns a significant share of the Borkum Riffgrund 1 in the waters of the Netherlands.
Energy use is far from being the only part of the toy manufacturing industry where some long-term sustainable thinking needs to be applied. The toy industry is one of the most intensive of all when it comes to its use of plastic.
But there is some progress being made. Finding non petroleum-based alternatives is the aim, and there are a number of possible options currently available, including bio-polymers, natural fibres mixed with recycled plastic, and entirely biodegradable plastics.
Some early-adopting toy companies are already finding these materials work for them, but for those with huge global profiles, the task can be trickier.
Such alternatives are under continuous development, and to that end, LEGO is pumping millions into finding sustainable materials that work well for its products by 2030. Crucially, it is looking for its product to look and feel no different, which is why it's dug deep into research and development funds and employed 100 staff to get the search under way in earnest.
But while the biggest firms like LEGO tend to hog the headlines, others are making big strides towards sustainability without making too much noise about it. PlanToys in Thailand have built a toy business out of plant products – quite literally.
Sustainably-sourcing wood from rubber trees after they're done producing latex products, the wood is dried without chemicals, dyed with water-based colours, and used to create a range of durable toys such as its best-selling dancing alligator. Even the packaging is made from recyclable cardboard, and printing done using soy.
That's not all. The factory is powered entirely by solar PV, there's a biomass power plant for waste products, it's reforesting degraded land, and commissioned a Life Cycle Assessment (LCA) on all its product range. The aforementioned alligator, as it happens, turned out to be carbon negative.
While it might be easier to quickly effect such direct sustainable approaches in smaller firms with more modest distribution networks, it's also arguable that the bigger budgets of multinationals could be channeled in a greener direction to huge effect.
There's certainly much food for thought, as those that bring joy to children aim to do a lot more for the wider world.
