CTX has electronically interfaced with carbon registries to ensure transaction transparency and efficiency

Registries are essential for issuing, holding, and transferring carbon credits. Once a carbon project is issued with credits, the registry gives each one a unique serial number so that they can be tracked through their entire life-cycle. Registries also facilitate the retirement (surrendering) of credits for carbon neutrality purposes, ensuring credits are not resold at a later date.



APX has grown into a leadership role over the last two decades through strong client support, proven infrastructure and reliable, cost-effective, 24/7 operations in there APX Environmental Markets and APX Power Markets businesses.

APX is a leading infrastructure provider for environmental markets in greenhouse gases including carbon commodities. These commodities include emissions allowances and carbon offsets, sometimes called Verified Emission Reductions (VERs), Emission Reduction Units (ERUs), Certified Emission Reductions (CERs), Verified Carbon Units (VCUs), or Carbon Reduction Tons (CRTs). Users of these systems include all key market participants such as project developers, brokers, corporations, NGOs and government organizations.
APX greenhouse gas and carbon market infrastructure systems include:

The Gold Standard

The Gold Standard is an award winning certification standard for carbon mitigation projects and is recognised internationally as the benchmark for quality and rigour in both the compliance and voluntary carbon markets. We certify renewable energy, energy efficiency, waste management and land use & forest carbon offset projects to ensure that they all demonstrate real and permanent greenhouse gas (GHG) reductions and sustainable development benefits in local communities that are measured, reported and verified.
Established in 2003 by WWF, The Gold Standard is the only certification standard trusted and endorsed by more than 80 NGOs worldwide, including Care International, World Vision Australia, Forum for the Future and Mercy Corps. It is also the standard of choice for multiple governments and multinationals such as H&M, DHL, Swiss Post, Nokia, Virgin Atlantic, Panasonic, TUI Travel and FIFA. United Nations agencies use the Gold Standard for the development of their own carbon mitigation and sustainable development projects.
Gold Standard projects must adhere to a stringent and transparent set of criteria developed by the Secretariat, overseen by an independent Technical Advisory Committee and verified by UN accredited independent auditors. The certification process uniquely requires the involvement of local stakeholders and NGOs.

To be eligible for Gold Standard certification, projects must:

  •  Employ renewable energy and/or energy efficiency technologies
  •  Adhere to the strictest standards on additionality
  •  Positively impact the economy, health, welfare and environment of the local community hosting the project

Climate Action Reserve (CAR)

As the premier carbon offset registry for the North American carbon market, the Climate Action Reserve encourages action to reduce greenhouse gas (GHG) emissions by ensuring the environmental integrity and financial benefit of emissions reduction projects.

The Reserve establishes high quality standards for carbon offset projects, oversees independent third-party verification bodies, issues carbon credits generated from such projects and tracks the transaction of credits over time in a transparent, publicly-accessible system.

The Reserve offsets program demonstrates that high-quality carbon offsets foster real reductions in GHG pollution, support activities that reduce local air pollution, spur growth in new green technologies and allow emission reduction goals to be met at lower cost.

The transparent processes, multi-stakeholder participation and rigorous standards of the Reserve help earn confidence that registered emissions reductions are real, additional, verifiable, enforceable and permanent. The Reserve’s expertise and insight helped inform the development of the State of California’s cap-and-trade program, which adopted four of the Reserve’s protocols for use in its regulation.

The Reserve began as the California Climate Action Registry, which was created by the State of California in 2001 to address climate change through voluntary calculation and public reporting of emissions. The California Registry helped over 415 leading California-based corporations, organizations, government agencies and municipalities to voluntarily calculate and publicly report their GHG emissions. Its established expertise in emissions accounting translated into expertise in emissions reductions accounting for the North American carbon market.

The American Carbon Registry (ACR) is a leading non-profit U.S. carbon market standard and registry. As the first private voluntary greenhouse gas (GHG) registry in the U.S., ACR boasts over 15 years of operational experience in development of high quality carbon offset standards and protocols, carbon offset issuance and serialization and transparent on-line transaction reporting. ACR has issued over 30 million carbon offsets and continues to lead voluntary carbon market innovation.
Founded in 1996 as the GHG Registry by Environmental Defense Fund and Environmental Resources Trust, American Carbon Registry, ACR has 15 years of experience in the development of rigorous, science-based carbon offset standards and methodologies, as well as in carbon offset issuance, serialization and transparent online transaction and retirement reporting.
As the first private voluntary GHG registry in the world, ACR has set the bar in the global voluntary carbon market for offset quality and operational transparency. The American Carbon Registry and Environmental Resources Trust joined Winrock International in 2007, expanding the Winrock team of climate change, forestry, clean energy, agriculture, biofuels and carbon market experts.
