CTX (Carbon Trade Exchange)
Carbon Trade Exchange (CTX) operates spot exchanges in multiple global environmental commodity markets, including carbon, Renewable Energy Certificates (RECs) and water. Carbon Trade Exchange allows buyers and sellers to trade voluntary credits, as well as those issued by a United Nations program established under the 1997 Kyoto Protocol.
Background
CTX was founded in London in 2009, after two years of research and development.
CTX uses technical IT infrastructure to support and operate its exchanges. CTX is currently operating in Australia, the EU and the US, and has the ability to expand into other jurisdictions and markets.
The CTX Exchange Platform interfaces with multiple environmental commodity registries, including APX, Climate Action Reserve, American Carbon Registry, VCS, Gold Standard and the Australian REC Registry. It also electronically links to financial intermediaries, such as Westpac in Australia, to provide efficient trading and create liquid and transparent markets.
CTX (explosive-detection device)
The CTX (Computer Tomography X-ray) is an explosive detection device, a family of x-ray devices developed by InVision Technologies in 1990 that uses CAT scans and sophisticated image processing software to automatically screen checked baggage for explosives. CTX scanners are by far the market leader in explosive detection systems (EDSs), accounting for approximately 150 out of 161 FAA-certified bomb scanners installed in US airports as of 2002.
CTX-5000
In 1994, the CTX-5000 became the first computed tomography explosive detection system certified by the US Federal Aviation Administration (FAA). The certification of the CTX-5000 followed nine years of development. During that time the FAA invested $90 million in explosives detection and nearly $8.6 million in the specific technology. From 1995 to 1997, the CTX-5000 was tested to solve the challenges involved in integrating an explosives detection system into a baggage system and to validate the estimated costs of wide-scale deployment of the systems.
