Choosing well
Start with access and pricing
Decide whether web access is enough or whether your team needs an API, iOS, Android or Windows option. Check the product details for a supported app before relying on phone or tablet work.
Some listed services provide a free plan, while certain paid products offer trials. Several paid products quote prices on request; Microsoft Sustainability Manager lists a price from $4,000 per month.
Check emissions coverage
Compare the emissions scopes a product handles and whether its accounting includes Scope 3. Scope 3 data can require information from suppliers and other parts of a value chain.
Look for reporting standards that match your organisation's obligations and the reports you need to produce.
Review data workflows
Data integrations can reduce manual collection from business systems. Supplier data collection features help bring external activity data into the same process.
Ask how the service accepts, checks and updates source data before selecting it for a larger reporting workflow.
Plan for assurance
For figures subject to external review, examine each product's stated assurance support. Check whether the workflow can retain the records and evidence your reviewers require.
