Carbon cycle. The term used to describe the exchange of carbon (in various forms, e.g., as carbon dioxide) through the atmosphere, ocean, terrestrial biosphere and lithosphere. (Source: IPCC, 4th Assessment)

Carbon Dioxide Emissions from Fossil Fuels (CO2). Emissions from fossil fuels is the amount of CO2 that is released when fossil fuels are burned for generation of heat and power. Fossil fuels are normally burned in power boilers, but can also be fired directly in the process e.g. for paper drying or space heating. (Lime re-burning is also done with fossil fuels in lime kilns, and its contribution to CO2 is accounted for).

Carbon Dioxide-equivalent Emissions (CO2-e). The amount of greenhouse gases emitted as a result of the production and distribution of the product and expressed in CO2 as a common unit of measure. It determines the impact of a manufacturing operation on climate change.

Carbon Sequestration. The various processes through which carbon is removed from the atmosphere and stored in soil, biomass, geological formations and oceans. (Source: IPCC)

Certification. A process whereby an independent auditing body (third party) conducts an inspection and awards a certificate using independently developed standards and objectives. (Source: Metafore)

Certified Forest Management. A measure of whether the raw materials came from a forest that was determined to meet an independent sustainable management standard. A number of different certification programs are in use in the world at this time.

Chain of Custody (CoC). The systematic tracking of wood-based products from their origin in the forest to their end use demonstrated through chronological documentation or paper trail.

Climate change. A change in the state of the climate that can be identified by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer. Climate change may be due to natural internal processes or external forces, or to persistent anthropogenic changes in the composition of the atmosphere or in land use. (Source: IPCC)

Climate change. Change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods. (Source: UNFCCC)

Deforestation. The permanent clearing of forest for other uses such as agriculture and urban development.

Deinking. A process which removes most of the ink, filler and other extraneous material from printed and/or unprinted recovered paper. The result is a pulp which can be used, along with varying percentages of wood pulp, in the manufacture of new paper, including printing, writing and office papers as well as tissue.

Greenhouse effect. Greenhouse gases effectively absorb thermal infrared radiation, emitted by the Earth’s surface, by the atmosphere itself due to the same gases, and by clouds. Atmospheric radiation is emitted to all sides, including downward to the Earth’s surface. Thus greenhouse gases trap heat within the surface-troposphere system. (Source: IPCC)

Greenhouse gas (GHG). Those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of thermal infrared radiation emitted by the Earth’s surface, the atmosphere itself, and by clouds. Water vapor (H20), carbon dioxide (CO2), nitrous oxide (N20), methane (CH4) and ozone (O3) are the primary greenhouse gases in the Earth’s atmosphere. (Source: IPCC)

Groundwood. Paper made from pulp created in one of several processes that use virtually the whole tree. In the early days of papermaking, the tree was simply ground up. Now chemical and heating processes are also used in pulping. Groundwood paper retains the lignin from the original trees, which causes the paper to yellow and deteriorate relatively rapidly, faster than freesheet grades.

It contains legally binding commitments, in addition to those included in the UNFCCC. Countries included in Annex B of the Protocol (most Organization for Economic Cooperation and Development countries and countries with economies in transition) agreed to reduce their anthropogenic greenhouse gas emissions (carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride) by at least 5% below 1990 levels in the commitment period 2008 to 2012. The Kyoto Protocol entered into force on February 16th 2005.

The Act combats trafficking in “illegal” wildlife, fish or plant. The Food, Conservation, and Energy Act of 2008, effective May 22, 2008, amended the Lacy Act by expanding its protection to a broader range of plants and plant products (Section 8204, Prevention of Illegal Logging Practices). As amended, the Lacy Act now makes it unlawful to import, export, transport, sell, receive, acquire, or purchase in interstate or foreign commerce any plant, with some limited exceptions, taken in violation of the laws of a U.S. State or any foreign law that protects plants. (USDA 2009)

Nitrous oxide (N2O)– one of the six types of greenhouse gases to be curbed under the Kyoto Protocol. The main anthropogenic source of nitrous oxide is agriculture (soil and animal manure management), but important contributions also come from sewage treatment, combustion of fossil fuel, and chemical industrial process. Nitrous oxide is also produced naturally from a wide variety of biological sources in soil and water, particularly microbial action in wet tropical forests. (IPCC 2007)

Sheets 12 points (0.012 inch) or more in thickness are classified as paperboard. There are exceptions. For example, blotting papers, felts, and drawing paper in excess of 12 points are classified as paper, while corrugating medium, chipboard, and linerboard less than 12 points are classified as paperboard.

Its ultimate objective is the “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system”. (IPCC 2007)

Waste energy– is derived from the following sources; mass burning of garbage; conversion of garbage to refuse-derived fuel pellets for eventual burning; collection of methane gas from landfills; and burning or anaerobic digestion of wastes. (Energy Information Administration: Renewable and Alternative Fuels)

Wood energy– is derived from the following sources: roundwood, used primarily in the industrial and electric sectors; woodfuel, used predominantly in the residential and commercial sectors; and wood byproducts and wood waste, which are usually used in the industrial sector.
