Global project development and credit sourcing
Generating and purchasing high quality international carbon credits
GreenCollar’s global operation is headquartered out of Washington DC and Australia and supported by a team of recognised international experts that oversee a large and diverse network of projects and carbon credit suppliers across the globe.
Sigma Global merged with GreenCollar in 2021. This merger together with the addition of key new staff members expands GreenCollar’s capabilities. GreenCollar now offers a complete service for the design, preparation and registration of projects and ongoing support for registered projects, as well as the procurement of international carbon offsets.

Our Expertise
Long track record
Our team has decades of experience supporting projects, countries, NGOs, industry and commodity producers in climate law and policy, greenhouse gas accounting, emission reduction pledges and reporting. With an enviable track record in delivering high quality, high integrity environmental projects and credits, we are trusted by buyers, by standards and registries, as well as the organisations we work with.
Methodology development
GreenCollar is proud to have exceptional staff who have led forest and land use climate change mitigation work for almost two decades. Our staff authored many of the standards and methodologies upon which the market is based.
Local project development
With projects underway in Asia, the Pacific and Africa, GreenCollar is skilled in working in partnership with local populations, governments, civil society and other stakeholders to deliver high integrity projects. Our focus is is land use related projects and nature nature based solutions that deliver multiple environmental, social and economic benefits.
Depending on a projects’ needs we can provide upfront and ongoing finance until a project is self-sustaining. Once involved in a project we take full responsibility for ensuring success. We run all technical aspects of the project, including project design, preparing project documents and reporting and verification throughout the life of the project. We also take on the cost and risk of our early involvement, so our success is wholly tied to the project’s success.
