Choosing well
Check Android and web access
If you need to review ESG data from a Xiaomi, Redmi or POCO phone, confirm that the service offers an Android app. EcoOnline lists Android and iOS; other services list web or API access instead.
Check browser requirements and whether staff need Windows, iPhone or iPad support. Platform listings can differ between products.
Match emissions tracking needs
Compare whether the service provides GHG accounting and Scope 3 tracking. Arbor describes company and product emissions measurement, while the category comparison includes both GHG accounting and Scope 3 as separate checks.
Choose a service whose emissions workflow matches the boundaries and data sources you need to manage.
Review reporting and assurance features
Framework coverage, materiality assessment, assurance workflows and reporting exports indicate how a service handles preparation and review. Check the frameworks and export formats offered before signing up.
Supplier data portals can matter when sustainability information comes from vendors or supply-chain partners.
Compare free plans and pricing
A free plan is available from items in this category, while paid pricing ranges from published starting prices to quotes on request. Brightest lists a free plan and paid pricing from $5,900 per year; ESG:ONE lists pricing from £3,000 per year.
Check whether a free plan covers the reporting work you need, then compare paid-from prices, user terms and quote-based costs.
Check licences and data handling
If you need to read or change code, check the tool's licence.
