Marlot Kiveron
Marlot Kiveron is a sustainability expert and author of De Impactmissie. She was a pioneer in the role of sustainability manager at Ace & Tate, where she developed a strategy focusing on circular business models and industry collaboration. She then spent four years at Otrium, establishing the sustainability strategy with a focus on extending the lifecycle of fashion items and B-Corp certification. Marlot is co-founder of the AMS Sustainability Network and recently started as Sustainability Director at Karl Lagerfeld.
Based on her experience, she published her book De Impactmissie in 2025. A practical guide to creating meaningful change within organizations. What started as a personal mission to make the business world more sustainable has grown into a powerful model for bridging the gap between commerce and sustainability. With concrete steps and strategic insights, she shows how to integrate impact into business models.
Marlot is nuanced, well-read, and authentic in her approach. She does not believe in one-size-fits-all solutions or bold statements. “In the end, we all wear different hats—as consumers, professionals, and voters. By applying our personal values in all these roles, we can transition to a new economy. An equitable economy in harmony with the rights of humans, animals, and nature.”
In 2017, Marlot became the first Sustainability Manager at Ace & Tate, the Dutch direct-to-consumer eyewear brand. She initiated the topic of sustainability from her role in the company’s supply chain team. She realized that she could make the most impact by dedicating herself to making the company more sustainable, so she changed course and retrained herself in her free time. As a Sustainability Manager at the eyewear brand, she combined creating a positive impact with cost savings and new revenue streams. The business model was expanded with various circular models such as reuse, repair, and recycling. She also led the journey to becoming a certified B Corp.
At Otrium, a platform that connects fashion brands and consumers to give new, unsold fashion items a second chance, Marlot was also the first sustainability professional and ultimately responsible for Sustainability and ESG. Her focus was on the impact of the business model, operations, and the structural integration of positive impact and ESG within and around the organization. In this role, she engaged consumers, fashion brands, and the value chain that Otrium works with in new initiatives.
Marlot combines her background in economics with her mission to create structural positive impact within commercial organizations. Her approach is known for fostering internal and external collaboration, thereby raising awareness and demand for sustainable solutions. In addition to her own role as a sustainability professional, she analyzes the challenges of the field. “The topic of sustainability is extensive, holistic, and constantly evolving. This makes it, in every aspect, an outlier within the corporate world.”
Together with Amber Westerborg, Marlot founded the AMS Sustainability Network—a peer-to-peer network for sustainability professionals within commercial organizations. The goal is to strengthen each other with knowledge and personal support. Working as a sustainability professional in a commercial organization can be challenging. You are often the only one with this expertise, have a deep emotional connection to the topic, and it can feel like you are always swimming upstream.
In 2019, her work was recognized with her selection for the Sustainable Young Top 100 Netherlands. During Circular Economy Week, she was named Circular Action Hero by CIRCL and ABN AMRO. She has spoken at organizations such as ABN AMRO, Bloomon, and Netflix. She has also been a panelist at events such as Amsterdam Fashion Week and Dutch Design Week. Marlot gives guest lectures at Cambridge, Nyenrode, and AMFI. Twice, she served as a jury member for the Sustainable Retail Award in 2019 and 2021. She has also been featured in podcasts by Edie and ERM/Sustainalize.
