Greenstone is one of the leading companies working in partnership with public sector and commercial organisations to enable them to measure, manage and report their carbon emissions and other responsible sourcing data.Greenstone offers two innovative systems for tracking carbon emissions – the enterprise-level carbon management software Acco2unt and a responsible sourcing portal, SupplierPortal.

Acco2unt is a global carbon accounting software enabling organisations to measure, manage, plan, and report carbon emission data, track performance at multiple organisational levels and model the impact of carbon reduction strategies. Acco2unt can significantly reduce the burden of calculating carbon emissions across multiple sites and sources, enabling clients to focus on analysing the results and developing targetedcarbon reduction projects.An extensive range of emission sources is included in the calculation methodologies covering energy, refrigerants, travel, freight, waste, water and ICT.  All carbon emission calculations are processed automatically according to recognised international and national methodologies, including Defra (UK) and the GHG Protocol.  Acco2unt is currently deployed in over 100 organisations in 95 global locations.

SupplierPortal is a user-friendly online responsible sourcing solution for suppliers and their buyers to track and monitor environmental, labour, health and safety and anti-bribery and corruption information. Facilitating efficient communication between buyers and suppliers, SupplierPortal enables suppliers to report key responsible sourcing data and calculate their carbon, waste and water footprints, whilst buyers can view and compare their suppliers’ performance across key responsible sourcing metrics.

Greenstone’s central proposition is to enable its clients with the necessary tools, skills and knowledge to measure and manage their data on an ongoing basis, allowing them to report against regulatory and voluntary schemes, meet stakeholder requirements and report internally and externally.

Greenstone has been awarded a place on the G-Cloudiii framework for the supply of Software as a Service (SaaS) solutions.
