Environmental, Social and Corporate Governance
Our commitment to wellness applies not only to the patients who rely on our products but also to our employees and our business practices. Environmental, Social and Corporate Governance (ESG) is so much more than a strategy at Lantheus. It’s a way of life. One that ensures our employees, partners and shareholders can feel good about the work we do. Every day. In every environment.
This commitment stems from our purpose to always make a positive impact, and it’s reflected in our values to help and respect one another while driving solutions as one to benefit all.
Environmental
Our industry functions within a global ecosystem and we know that our actions must preserve and protect the environment. Sustainability is at the forefront of everything we do.
In 2024, we strengthened our focus on regulatory compliance and data collection by implementing third-party environmental software. This investment improved controls over our data gathering, enhanced visibility into our greenhouse gas emissions and is helping us build the capabilities needed to ensure our reporting of them is comprehensive and aligned with emerging regulatory requirements.
Annual greenhouse gas emissions
- 2024 changes included re-baselining to include all Lantheus locations, and reporting in Scope 1 and Scope 2 emissions as opposed to emission source, with perfluoropropane used in DEFINITY® (“PFP”) and fugitive emissions from refrigeration included in Scope 1 emissions.
- 2023 increase in PFP use correlated to increased volume of DEFINITY® manufacturing.
- Scope 1, Direct Emissions: Natural gas combustion, diesel combustion, PFP, fugitive emissions from refrigeration.
- Scope 2, Indirect Emissions: Electricity use, significant decrease starting in 2022 due to the purchase of renewable wind energy at our North Billerica location.

Recycling initiatives
Lantheus also continued to demonstrate recycling best practices with participation in the RightCycle Program, a large-scale industrial recycling initiative in the scientific and industrial products industries for nonhazardous laboratory gloves, single-use apparel, face masks and safety eyewear. We also co-hosted several electronic recycling events.

Social
We value a culture where different perspectives are respected and collaboration thrives. We support initiatives that foster connection, accelerate growth across our organization and let people be their best.
Guided by this value, we empower our employees to take action in the communities we serve by investing in charitable partnerships that turn shared ideas into action. Together with mission‑driven organizations, we support programs that strengthen communities, expand opportunity and help people thrive.
Governance
Our corporate culture is rooted in ethical conduct, integrity and transparency. From mandatory training on business practices to accuracy in financial reporting, we remain committed to principles of behavior that meet the highest standards—and those of our formal Ethics and Compliance Committee. We also maintain codes of conduct with our suppliers to ensure they’re operating in a legal, ethical and socially responsible manner.
