Neste's self-service station chain in Poland was sold to Royal Dutch Shell in April 2013. In the same month, Neste announced that it had started cooperation with The Forest Trust (TFT), an organization that focuses on combating deforestation. During 2013, Neste abandoned its shipping operations; it sold eight vessels (five tankers and three tugboats) owned by Neste Shipping to a shipping company owned by the National Emergency Supply Agency and Ilmarinen Mutual Pension Insurance Company, which began to lease the vessels to Neste. The holding company owns the vessels, which are operated by a separate ship management company. Ensuring supply security was one of Neste's responsibilities. However, this was at odds with the company's operations in the international market. After the change of ownership, the vessels continued to employ a Finnish crew and sail under the Finnish flag. Neste Oil kept three tankers as well as ships owned on a fifty-fifty basis with Swedish company Stena, which it intends to sell later. These ships were not needed to ensure supply security.
