Allegations

On 9 December 2025, Opportunity Green filed a complaint against Luxembourg-headquarted steel company ArcelorMittal S.A to the Luxembourg NCP. The complaint is supported by SteelWatch, BankTrack, and Ecologistas en Acción. The complaint highlights ArcelorMittal’s lack of a robust, science-based climate strategy and outlines how it is failing to take adequate action to reduce its emissions at the pace and scale required to adhere to the 1.5ºC global temperature limit in the Paris Agreement. Opportunity Green contends that the targets, strategies and actions undertaken by ArcelorMittal to address its adverse environmental and human rights impacts fall short of the expectations set out in the OECD Guidelines. Opportunity Green seeks to ensure that ArcelorMittal conforms to these responsible business expectations, including by publishing a revised climate action strategy within six months that will ensure its greenhouse gas (GHG) emissions are consistent with the internationally agreed global temperature goal, and within that strategy to adopt GHG reduction targets.

In a press release, Kirsty Mitchell, Legal Manager at Opportunity Green said:

“If ArcelorMittal is going to live up to its promise of achieving net zero emissions by 2050, it needs to take decisive, transformative action right now. Instead, the company is signalling a retreat from action and a lack of strategic clarity – with alarming knock-on effects for the climate and communities. By bringing this complaint, we hope to engage with ArcelorMittal on the actions it must take to address its climate impacts in line with the OECD Guidelines, and demonstrate that the company – and the wider industry – are accountable for climate action.”
