Sustainability Certification Software for Hotels
Hotel sustainability certification software is a platform that collects a property's evidence once, maps each document to the criteria and indicators of a chosen standard, and generates the audit-ready submission package. Alto Greenify does this across GSTC Hotel v4.0, GSTC MICE v1.0, Green Hotel Plus, Green Hotel and Travelife.

Everything a Certification Submission Needs, in One Workflow
Alto Greenify takes a hotel from a folder of scattered documents to a submission package a certification body can review.
Evidence is uploaded once, mapped by AI, approved by your team, and exported on demand.
Multi-Certification Workspace
One workspace, every standard — GSTC Hotel, GSTC MICE, Green Hotel Plus, Green Hotel, Travelife, and more.
Prove it once, reuse it everywhere. Evidence for one certification counts toward the next.
Every category, indicator, and requirement in a single view.
Bulk Evidence Upload
Drop in Excel, Word, PDF, images — all at once, or one at a time to close a specific gap.
Energy, water, emissions, procurement, waste, training, policy — it all fits.
One indexed library instead of scattered drives and email threads.
AI Evidence Analyzer
Every file gets automatically mapped to the right criteria and indicators.
Gaps surface before your auditor finds them.
Evidence arrives to the auditor organized by indicator, not just by criteria — where most manual mapping time gets lost.
AI Sustainability Coach
Explain what each indicator actually means, in plain language.
Specify exactly what evidence a criterion needs.
Flag gaps based on what's already uploaded.
Recommend the next document to close gaps.
Human-in-the-Loop Approval
AI proposes, your team approves. No mapping enters the evidence base without a person accepting it.
Approved evidence counts across every certification that needs it.
Every action is logged and export-ready, so the audit trail shows who approved what and when.
Audit-Ready Report
Self-check report: an internal readiness tracker before you commit to an audit.
Audit-ready report: your sustainability report, covering all certification criteria and an evidence index organized by criterion code.
Evidence package: a folder of your evidence files organized by criterion code or indicator, with corrective actions flagged.

Certification Evidence That Comes Straight from the Building
The hardest evidence to assemble is the operational kind — energy, water and emissions records covering a full reporting period. Alto CERO already collects it. Properties running Alto CERO feed monitored consumption data into the same evidence library the AI Analyzer maps, so the environmental section of a submission is built from live building data rather than reconstructed from bills.
Common questions about preparing GSTC, Green Hotel Plus and Travelife certification with Alto Greenify.
What is hotel sustainability certification software?
A platform that collects a hotel's evidence once, maps each document to the criteria and indicators of a chosen certification standard, flags what is missing, and generates the audit-ready submission package — replacing spreadsheets, shared drives and manual consultant mapping.
Which certifications does Alto Greenify support?
Five standards today: GSTC Hotel Standard v4.0, GSTC MICE 1.0, Green Hotel Plus, Green Hotel, and Travelife. Additional standards are added according to regulations and hotel needs.
Will auditors accept AI-mapped evidence?
The AI proposes a mapping; hotel staff approve it. Nothing enters the submission without human sign-off, and every action is logged and export-ready, so the audit trail shows exactly who accepted each mapping.
Can we reuse existing documents across more than one certification?
Yes. Greenify maps existing policies, utility bills, records and IoT data across the criteria of every standard you select, so the same evidence base serves multiple certifications instead of being re-collected for each.
What file types can we upload?
Excel, Word, PDF and image files, in bulk or one criterion at a time.
What is in the audit-ready package?
Two report types plus an evidence folder. The audit-ready package is a submission package that includes an organized evidence folder and a report per-criterion narrative with indicator and KPI tables, and an evidence index organized by criterion code. Exports as PDF or DOCX.
