Last week, I attended the [opening of European Energy’s new e-methanol factory in Kassø][1], Denmark – the world’s first large-scale commercial facility. This event was an important milestone, both for Denmark’s renewable energy ambitions and for the LEGO Group’s commitment to using more sustainable materials by 2032. 

Standing alongside like-minded companies, I was truly inspired by the shared drive to take action and create lasting change. European Energy’s groundbreaking work with e-methanol is a critical step forward, and we’re proud to support this initiative alongside Novo Nordisk and Maersk.   

Later this year, we’ll start using e-methanol from the factory to make ePOM – a more sustainable material that helps us create hard, durable LEGO® elements such as wheel axels, connectors and even our minifigure hands. Importantly, the innovative manufacturing approach allows us to maintain the same high standards of quality and safety. In fact, you won’t be able to tell the difference – and that’s the point. The LEGO play experience remains the same, while reducing our environmental impact. 

E-methanol is just one part of our broader portfolio of sustainable materials. There’s no single solution to tackling climate change. It requires many solutions moving in parallel and evolving as technology advances. So far, we’ve tested more than 600 different materials. 

Some of our products already use these sustainable alternatives, like Brazilian sugarcane for 200 of our flexible elements, recycled fishing nets and recycled engine oil to make some of our tyres, and artificial marble – commonly used in kitchens – for our transparent pieces. We’re pleased with our progress – nearly half of the materials purchased in 2024 were produced with sustainable sources. E-methanol will help us go even further in reducing our use of virgin fossil materials.  

But we can’t solve these problems in isolation. Collaboration and partnerships like this are essential. By working across industries, we can accelerate innovation, scale meaningful solutions and set new industry standards that no company could achieve independently.  

Children are our role models, and we’re committed to helping them inherit a healthy planet. That means embedding sustainability into everything we do — from the materials we source and how we operate our factories, to how we collaborate across industries to tackle climate change. 

The Kassø factory is a powerful symbol of what’s possible when ambition meets action. And like any great LEGO creation, sustainable solutions like this are bigger and bolder when built together.

What do wheel axles, connectors and minifigure hands have to do with the opening of a new e-methanol factory in Kassø?
Quite a lot, actually.

***The first International Day of Play is celebrated on June 11, 2024. On this day every year hereafter, the world will celebrate the power of play.***

Play is never just play. Play is universal and taps into children’s natural enthusiasm and curiosity to learn. Play teaches children to explore, to wonder, to connect ideas and experiences and help them gain a deeper understanding of the world that surrounds them. When children play, they develop essential life skills such as creativity, confidence and resilience that help them thrive as they grow up.

Playing takes little more than picking up a stone or a stick. The only real investment is time. Yet, both parents and children indicate that the demand for children’s time away from play is increasing – with play time often being deprioritized. 

In a recent survey of 25,500 children and 36,000 parents in 36 countries commissioned by the LEGO Group, 59% of parents indicated they worry that their children do not have enough playtime, do not have enough access to fun activities and worry that their child does not have enough playtime as a family.

Almost all children said play is important for their well-being. 91% of parents said that play improves their family’s overall wellbeing, and families who play rated their own happiness higher than those who don’t. 

Yet, the average parent reported spending twice the amount of time by themselves on their electronic devices than they do playing with their family. 20% of parents surveyed said they never spend time playing as a family, mirroring 73% of children who think parents do not take play seriously. 
These figures are worrisome because play is important for both the development and the well-being of children.

According to Centre on the Developing Child at Harvard University, the first five years in a child’s life are extremely important. Much of the learning that goes on comes from play. And throughout childhood, play is a way for children to develop key life skills like creativity, confidence, and resilience that help them thrive. 

We also know that play improves well-being. Both in moments of happiness and when facing challenges, children can find their way back to health and happiness, through play. Because of our jobs, we both frequently interact with children and parents when they play. The focus, joy and creativity unleashed never cease to amaze.

On a societal scale, economies are set to lose out on big social and economic benefits if early childhood development and play is not prioritised. A recent report by The Royal Foundation Business Taskforce for Early Childhood estimated that investing in early childhood in the UK could add up to £45.5 billion to the national economy each year. 

Simply put, playing is natural, healthy and part of being human - but it is also fundamental to personal and societal progress.  

This has long been recognised by the international community. Indeed, the UN Convention of the Rights of the Child, which almost all countries in the world have signed, recognises the right to play. And earlier this year, in a nod to the importance of this universally human activity, the UN General Assembly adopted an International Day of Play. 

On 11 June this year, and every year hereafter, we will celebrate the power of play.  

It’s a day to take stock, reflect and act. That is why today, we ask governments, organisations, schools and parents to:
 - Prioritise the space and time children need to play.
 - Improve resources and policies for educators, parents and caregivers to facilitate quality play.
 - Increase access to quality play for children facing additional barriers such as special educational need and disabilities, poverty or conflict. 

We ask you to join us in championing the cultural change needed and put play back on the agenda for kids everywhere. Our future depends on it.
