One of the requirements, says ESG Today, means that suppliers will have to set emission reduction strategies, as well as to report on the progress they make towards more sustainable models. Last year, the LEGO Group set a goal for carbon neutrality for 2050, while aiming to reduce its emissions by 37% before the end of 2032.

As it is the case for many companies that rely heavily on suppliers, most of LEGO's carbon footprint comes from Scope 3 emissions, which the company has no direct control of. In fact, over 99% of the footprint associated with the Danish company originates from outside its own operations, so from raw materials suppliers, as well as services, machines and products.

Value chain emissions are some of the most difficult to address, and LEGO announced last year that it dropped plans to create construction bricks from rPET plastics made from recycled bottles.

The company has invested "more than €1.13 billion in sustainability initiatives as part of efforts to transition to more sustainable materials and reduce our carbon emissions by 37 per cent by 2032". Lego officials said at the time that researchers are looking at other ways to sustainably manufacture some of the world's most iconic toys, by using plastics made from e-methanol.

Annette Stube, Chief Sustainability Officer at the LEGO Group, said that "to put it simply, a net-zero world is simply not possible unless we find solutions that are greater than our own operations. We will not be able to meet our sustainability targets alone – we have to work in partnership with our suppliers."

LEGO experts will collaborate with the company's suppliers in order to help those achieve sustainability-related goals, carbon accounting being the initial priority.
