Archival: Acid-free (alkaline pH) sheets are used for projects requiring longevity as they offer the best protection against discoloration or deterioration over time. Papers made from 100% cotton contain low acidity and are frequently used for archival purposes.

Carbon Footprint: This is the total amount of carbon dioxide (CO2) and other greenhouse gases emitted over the full life cycle of a product or service.

ECF (Elemental Chlorine-Free): Paper fiber that has been bleached with alternative chlorine compounds as a substitute for elemental chlorine, which is harmful to the environment.

FSC (Forest Stewardship Council): The FSC recognizes products that meet rigorous standards for responsible management of forest resources. It is the global benchmark for responsible forest management.

Green Sealâ„¢: A non-profit organization working to achieve a healthier, cleaner environment by promoting environmentally responsible products and services.

PCF (Processed Chlorine-Free): Paper that is made from fiber recycled from post-consumer waste (PCW) and unbleached or bleached without chlorine compounds. PCF paper is the most environmentally friendly type.

PCW (Post-Consumer Waste): Paper that has been put to its intended use and has been recovered from the waste stream and recycle to make new paper.

Pre-Consumer Waste: Recycled from waste at the paper mill or printer. It is content recovered from waste that has never reached the consumer.

Recycled paper: Made with a variety of different percentages of recycled paper fibers, ranging from 10% to 100%, with recycled content falling into two different categories: Pre-Consumer and Post-Consumer recycled fiber.

Sustainability: Meeting the needs of the present without compromising the ability of future generations to meet their own needs.

SFI (Sustainable Forestry Initiative): A forest management program that balances the demand for wood products with the need for forest sustainability.

TCF (Totally Chlorine Free): Designated for virgin fiber papers, the TCF label indicates that no chlorine or chlorine compounds were used in the pulping process.

Tree Free: Papers made from plant fibers such as kenaf, hemp, flax and cotton.

TRF (Totally Recycled Fiber): Paper made from 100% recycled material and may contain pre- and post-consumer content.

Virgin Fiber: Paper made without any recycled or alternative fibers. Virgin fibers generally come from trees, but they can also be made from alternative plant sources such as hemp or rice.
