GRESB Leadership
Abisko simplifies GRESB reporting via workflows that validate data, track submission readiness, maximize scores, and enable stress-free submissions. We worked directly with GRESB technical teams to:
Review all methodologies and assumptions
Validate energy, water, waste, and emissions calculations
Approve REC allocations, gap-filling methods, and data availability algorithms
This rigorous review and validation process distinguishes Abisko from legacy solutions and ensures accurate submissions that align with GRESB reporting guidelines.
