GaC

GAC is an acronym that can refer to several different organizations and concepts depending on context. The most common uses are Global Affairs Canada, the Gulf Agency Company Group, and granular activated carbon.

Global Affairs Canada (GAC) is a department of the Government of Canada responsible for diplomacy, international development, and international trade. It operates Canada’s diplomatic missions abroad, coordinates policy with international partners, and administers development assistance. The department also engages with multilateral organizations and negotiates trade agreements on behalf of the country. In communications and official documents, the acronym GAC is often used to denote the department.

GAC Group, short for Gulf Agency Company, is a multinational provider of shipping, logistics, and marine services. Founded in 1956 in Dubai, it operates through offices worldwide and offers freight forwarding, warehousing, supply chain management, and ship agency services for commercial, offshore, and government clients.

Granular Activated Carbon (GAC) refers to a form of activated carbon with small, discrete granules. It is produced from carbon-rich materials such as coal, coconut shells, or wood and is valued for its porous structure. GAC adsorbs a range of contaminants from liquids and gases, making it widely used in drinking-water and wastewater treatment, air purification, and industrial processes. Regeneration or replacement restores its adsorptive capacity.

The acronym GAC is also used by other organizations and in various technical fields. Context usually clarifies which meaning is intended.
