Sustainability Score
65%
Second Nature shows moderate commitment to sustainability with recyclable packaging and USA-based manufacturing reducing transport emissions. However, they lack transparency regarding their complete supply chain and detailed environmental impact reports. While they use some eco-friendly materials, there's room for improvement in their overall environmental initiatives and public disclosure of sustainability metrics. Their labor practices appear fair but could benefit from more detailed reporting.
