The circular economy is an economic model that aims to avoid waste and to preserve the value of resources (raw materials, energy and water) and keep them in a ‘closed loop’ for as long as possible. Products and materials are continuously (re)circulated - as opposed to a linear model in which they are discarded as waste after use.
CO2 (Carbon Dioxide)
A naturally-occurring chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure; it exists in Earth’s atmosphere in this state, as a trace gas at a concentration of 0.39 percent by volume.
Cold ironing is the process of providing shoreside electrical power to a ship at berth while its main and auxiliary engines are turned off. The term came into existence during the time when ships were coal fired. Once the coal fired ship was in port and attached to a shore-based power source the engines no longer needed to be stoked by coal and the fires would die down until the large iron engines grew cold. Hence, cold iron became cold ironing.

Global Warming Potential (GWP)
A relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide. A GWP is calculated over a specific time interval, commonly 20, 100 or 500 years.
The set of rules (laws and corporate regulations), organizational structures, processes and relationships that affect the way a company is directed and administered. The concept of governance also embraces the structure used to decide corporate objectives and the means to achieve and measure results.
Wastewater that is generated from activities such as laundry, bathing, cooking and dish washing.
Greenhouse Gas (GHG)
A gas in the atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect, which many believe is the cause of global warming. The primary greenhouse gases in the Earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth’s surface would be on average about 33 degrees C (59 degrees F) colder than at present. The greenhouse gases thought to be major contributors to global warming are carbon dioxide (CO2); methane and biomethane emissions (CH4); nitrogen oxide (N2O) and chlorofluorocarbons (CFC).

The Greenhouse Gas Protocol Initiative’s vision is to harmonize greenhouse gas emission accounting and reporting standards internationally. It aims to provide a multi-stakeholder framework ensuring that different trading schemes and other climate-related initiatives adopt consistent approaches to GHG accounting.

Energy produced outside the reporting organization’s boundary that is consumed to supply energy for the organization’s energy needs (e.g., electricity, or for heating and cooling). The most common example is fuel consumed outside the reporting organization’s boundary in order to generate electricity to be used inside the organization’s boundary.
