Sustridge Information

Sustridge is a corporate sustainability and carbon advisory firm specializing in audit-ready greenhouse gas inventories and defensible ESG systems. As climate disclosure requirements expand and assurance expectations increase, companies need more than emissions calculations. They need structured governance, documented methodology, and reporting systems that withstand regulatory and investor scrutiny. We help organizations build: • Audit-ready Scope 1, 2, and 3 GHG inventories • Carbon assurance preparation and documentation systems • Double materiality assessments aligned with CSRD and ESRS • Science-based target development and SBTi alignment • Decarbonization strategy and emissions reduction roadmaps • Sustainability governance and ESG reporting programs Our work is aligned with recognized standards including GHG Protocol, ISO 14064, CSRD, ESRS, ISSB, and leading investor frameworks. We partner with mid-market companies, private equity portfolio companies, and organizations transitioning from voluntary sustainability reporting to regulated, investor-grade disclosure. Sustridge was founded by Josh Prigge, a sustainability and ESG advisor with more than 15 years of experience across energy, manufacturing, food and beverage, logistics, dairy, and technology sectors. His work integrates technical carbon accounting expertise with practical business execution. If your organization is preparing for carbon assurance, regulatory disclosure, or structured ESG governance, Sustridge can help you build systems that are accurate, defensible, and aligned with long-term business performance.
