Syria: A report into the alleged activities of Lafarge Syria, now part of LafargeHolcim, claims that the company paid a total of US$5.6m to a number of local factions in Syria, including to the Islamic State group, between July 2012 and September 2014. The report by the US consultant Baker McKenzie in collaboration with PricewaterhouseCoopers was first reported upon by the French satirical weekly Le Canard enchaîne (The Chained Duck).

According to Le Canard enchaîne, a large portion of the payments were paid to ensure the safety of local staff and the free movement of Lafarge trucks, often blocked by fighters at checkpoints. Groups were also reportedly paid as suppliers, as they controlled access to heavy fuel oil or certain raw materials in part of the region. The document prepared by Baker McKenzie states that the Islamic State group could have collected at least US$500,000. The French Ministry of the Economy took legal action in 2016 on possible offenses committed by the cement group Lafarge by operating a plant in Syria, despite EU bans.

LafargeHolcim has maintained its stance that it ‘deeply regrets and condemns the unacceptable mistakes made in Syria’ and states that it called a central investigation as soon as it became aware of the irregularities. On 14 November 2017, police raided LafargeHolcim's offices in Paris and those of its 9.4% shareholder Groupe Bruxelles Lambert (GBL) in Brussels, Belgium. An investigation into the activities continues.
