Our Project Certification & Accreditation

The American Carbon Registry (ACR) is a nonprofit enterprise of Winrock International and one of the world’s leading carbon offset registries. Established in 1996, ACR sets rigorous standards for carbon offset projects, focusing on transparency, scientific integrity, and innovation in carbon markets.

BioCarbon Standard is a platform dedicated to the certification of climate change mitigation projects in forestry and land use. It focuses on enhancing the transparency and environmental integrity of carbon sequestration projects, particularly in Latin America.

CERCARBONO is a Colombian-based registry that certifies projects aimed at reducing carbon emissions, enhancing carbon sinks, and promoting sustainable development. It offers a robust framework for certifying emission reduction efforts, particularly in the Latin American region.

The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is a global scheme developed by the International Civil Aviation Organization (ICAO) to address the increase in total CO2 emissions from international aviation. It provides a standardized approach for airlines to offset their emissions, supporting the industry's commitment to carbon-neutral growth.

CSA Group is a global organisation dedicated to developing standards and testing, inspection, and certification services to ensure the safety, sustainability, and performance of products, systems, and services. Founded in Canada, CSA Group is well-regarded for its comprehensive standards in a wide range of industries, including energy, health care, and sustainability. The organisation also offers robust environmental and climate-related standards, including those for greenhouse gas (GHG) emissions reductions, helping companies and projects meet high standards for environmental integrity and safety.

The Clean Development Mechanism (CDM) is a carbon offset scheme under the Kyoto Protocol, allowing industrialized countries to invest in emission reduction projects in developing countries as a way to meet their own emission reduction targets. Projects registered under CDM are rigorously evaluated to ensure they provide real, measurable, and long-term climate benefits.

The Climate, Community & Biodiversity (CCB) Standards managed by Verra focus on land management projects that reduce greenhouse gas emissions while delivering net-positive benefits to local communities and biodiversity. These standards are designed to foster integrated, sustainable development outcomes alongside verified carbon reductions.

The Core Carbon Principles (CCP) established by the ICVCM are a set of high-level guidelines designed to ensure the quality and integrity of carbon credits. These principles provide a benchmark for evaluating the environmental and social impact of carbon reduction projects, enhancing trust in the voluntary carbon market.

The GHG CleanProjects® Registry by CSA Group is a platform that provides validation and verification for greenhouse gas emission reduction projects. It ensures that projects meet rigorous Canadian and international standards, offering transparency and credibility to stakeholders.

Gold Standard is a globally recognised certification body for high-quality climate and sustainable development projects. Established in 2003 by WWF and other NGOs, it ensures that projects not only reduce carbon emissions but also contribute to the United Nations Sustainable Development Goals (SDGs). Projects certified by Gold Standard must demonstrate genuine and measurable impacts on both the environment and local communities.

The Integrity Council for the Voluntary Carbon Market (ICVCM) is an independent governance body that sets and enforces global standards for the voluntary carbon market. It aims to ensure that carbon credits are credible, have environmental integrity, and contribute to sustainable development goals.

Plan Vivo is a certification standard focused on sustainable land use and community-led natural resource management projects. It ensures that projects contribute to climate change mitigation, while also enhancing the livelihoods of rural communities and preserving ecosystems.

The Plastic Waste Reduction Standard by Verra provides a robust framework for projects that reduce plastic waste in the environment. It enables the issuance of plastic credits for verified plastic waste collection and recycling efforts, fostering accountability and transparency in addressing plastic pollution.

Puro.earth is a marketplace and standard for carbon removal, focusing on biochar, carbonated building elements, and geologically stored carbon. It provides a transparent and efficient platform for businesses to purchase verified carbon removal certificates, supporting long-term carbon sequestration solutions.

The Sustainable Development Verified Impact Standard (SD VISta) by Verra is a flexible framework that enables projects to measure and certify their contributions to the UN Sustainable Development Goals. This standard ensures that projects not only reduce emissions but also generate positive social and environmental impacts.

Verra is a leading global standards organisation that develops and manages frameworks to measure, track, and certify various environmental and social impacts. Their flagship program, the Verified Carbon Standard (VCS), is one of the world’s most widely used voluntary carbon market standards, ensuring that carbon credits represent real, additional, and permanent emission reductions.

The Woodland Carbon Code is the UK’s voluntary standard for woodland creation projects that aim to sequester carbon dioxide. Projects certified under this code must meet high standards for sustainable forest management and carbon sequestration, ensuring that they deliver lasting environmental benefits.
