The Federal Trade Commission will hold a workshop to discuss green packaging terms as part of its review of environmental marketing claims.

The workshop will focus on packaging terms like recyclable, recycled content, biodegradable, compostable and refillable, along with terms not covered in the FTC's environmental marketing guides, such as sustainable and renewable.

The guides, called the Green Guides, were last updated in 1998.

Discussions will focus on terms covered by and not included in the Green Guides, what those terms mean to consumers, perception of environmental seals and third-party certification, trends in packaging that have led to green packaging claims, the impact of packaging on the environment and what guidance on green terms the FTC should provide.

This is the FTC's second Green Guides workshop. The previous one in January focused on marketing of carbon offset and renewable energy credits. The workshop will run from 9 a.m.-5 p.m. Wednesday, April 30, at the FTC satellite building conference center, 601 New Jersey Ave., N.W., Washington, DC. Comments can also be made online or by mail.
