The full Carlson product line is 100% plastic neutral. Carlson offsets the plastic in our products through investments in certified plastic removal projects taking place in our global waterways. To date, we’ve helped remove more than 1/4 million pounds of plastic, which is then recycled or upcycled. Look for the Reduced Plastic seal on Carlson products, and please recycle your bottle.
