BOSTON, (Reuters) – One of Carl Icahn’s nominees for director at McDonald’s Corp. (NYSE:), said that she will push McDonald’s to address sustainability issues such as lowering its environmental footprint and decreasing antibiotic usage.

Icahn the activist investor is well-known has so far focused his challenge for 2 seats on McDonald’s board over how McDonald’s treat pigs.

Green Century Capital Management’s president, Leslie Samuelrich, stated that ending use of gestation containers, like Icahn urged, would also have benefits, such as reducing pollution-producing factory farms.

Samuelrich spoke out in an interview to Reuters Thursday, saying that although they think the company is strong, it has some shortcomings regarding reputational risks and governance.

She stated that she had discussed her concerns with three McDonald’s executives this week and that the company hopes to make her a candidate for its board of directors later in spring.

McDonald’s declined to comment.

Samuelrich, a prominent voice in corporate environment issues is well-known. She led a 2018 effort that saw McDonald’s agree to limit the use antibiotics in beef supplies. Samuelrich expressed concern that McDonald’s is not following through.

McDonald’s claims that it works with partners to ensure responsible antibiotic usage and is currently “evolving its plan” in the face of COVID delays. The company also has said https://corporate.mcdonalds.com/corpmcd/en-us/our-stories/article/press-releases.response-carl-icahn.html it would evaluate Icahn’s nominees, and defended its treatment of animals.

Samuelrich stated separately that she supports the steps McDonald’s took in Russia as a response to Moscow’s invasion in Ukraine. As it pays its staff, the company is losing about $50M a month due to temporary Russian store closings.

Samuelrich stated that McDonald’s should be considering pulling out completely of Russia if Vladimir Putin, the Russian President, changes his mind.

This would be a way to “send an message to Putin’s leadership” and the residents of Russia about how Putin’s invasion was viewed abroad, she stated.
