321ZERO keeps your electricity, fuel, waste and travel figures in one place all year — so the annual return is a preparation task, not a scramble. Figures go in once and come out wherever they're needed: your annual return, a board update, a customer's questionnaire.
Use Jersey electricity, waste and water factors alongside recognised UK sources. Every result keeps its source visible.
Try a calculationTrack by scope and month so your team can focus on the changes with the greatest impact.
Turn the same underlying data into Eco-Active returns, Carbon Neutral Roadmap alignment, and clear figures for stakeholder updates.
Plain-English carbon reporting. No consultant vocabulary needed.
Enter monthly figures or import a spreadsheet. Start with electricity and fuel; add more when you’re ready.
The platform applies the relevant factor, shows its source, and organises each entry by emissions scope.
Follow your trend, brief decision-makers and export the records needed for annual reporting.
Choose an activity and enter the figure from a recent bill. This preview uses factors already present in the 321ZERO platform.
Different organisations have different hotspots. Start with the activities that matter to yours.
Bring electricity, heating fuel, laundry, food waste and guest travel into one view—then show visitors the progress you’re making.

Ask about Business AssistedPlan upgrades are arranged through a short conversation. Team access and public sharing require an active plan. Business Assisted support is scoped within the quarterly allowance described above. Features listed as planned are clearly marked and not included today. 321ZERO provides carbon data capture and reporting — it does not provide independent verification, assurance or government approval of your figures.
When you want us to run an agreed reporting process end to end. We scope the engagement around your organisation and you approve what is and isn’t included.
Request a scoped proposalConstruction example: relevant evidence — deliveries, plant fuel, waste transfers — is captured as the project runs, reported at agreed milestones, and exported at handover. Measured results are always shown separately from any early-stage forecast.
Up to two delivery hours against an agreed scope to set up your reporting. Never charged automatically; additional historical cleanup is quoted separately.
Up to three delivery hours, based on one clean dataset supplied by the customer, including one draft review and one revision. Required software access is additional. Data cleaning, reconstruction and additional complexity are quoted separately.

31 March each year, covering the calendar year before it. Eco-Active returns can include environmental actions completed, achievements in the previous year, priority actions for the year ahead, current organisation and contact details and — for Leaders — audit evidence. 321ZERO supports the carbon and closely related environmental evidence for your return; it does not complete every part automatically or guarantee acceptance. Because your figures stay organised all year, the return is a preparation task rather than a last-minute scramble.
Scope 1 is fuel you burn yourself (heating oil, company vehicles). Scope 2 is electricity you buy — in Jersey that uses the local grid factor of 0.0589 kgCO₂e/kWh. Scope 3 is everything else in your value chain: travel, commuting, waste, water and procurement. You enter bills; we put each line into the right scope.
Eco-Active Member is free: complete the gov.je form and set environmental actions. Eco-Active Leader needs a third-party standard such as ISO 14001, B-Corp, 5* environmental audit, or equivalent, plus audit certificates. Both levels submit an annual return by 31 March. We produce the emissions data for that return — we do not issue the accreditation itself.
Yes. With active Insights or Business access, the company owner can review and publish an annual carbon snapshot and embed it on a website. Private record changes are included only when the owner publishes an update.
Your electricity bill and any fuel receipts are enough for a useful first picture. Waste, water, travel and purchasing data can be added later.
No. Free lets one person start recording a business’s Scope 1, 2 and 3 emissions, view its history and download its records. Insights adds the tools to prepare your own reporting. Business Assisted adds a larger team and a quarterly support allowance to prepare reporting with our help. White Glove manages an agreed reporting process for you.
Yes. Downloading your own records as CSV is included in Free. The formatted Eco-Active return is an Insights reporting tool, currently available on Free at no charge. We will give reasonable notice before that changes.
After a scoping conversation, we prepare a custom proposal based on organisations, sites and projects, data volume, complexity, reporting frequency and the human effort involved — not employee count alone. Every inclusion is listed in the proposal before you commit.
Each Business Assisted support period is each successive three-month period beginning on the service activation date. Each period includes one 45-minute scheduled session and up to 45 minutes of asynchronous reporting assistance — checking data completeness and preparing your reporting. It is time to prepare your reporting with our help, not a managed service. Unused allowance does not roll over. Normal support for software faults is not deducted from this allowance. Additional work is agreed before it begins, so there are no surprise charges. You stay responsible for supplying information, approving figures and submitting returns.
Insights and Business Assisted do not include routine data entry, repairing your spreadsheets, bespoke calculations, consultancy, custom reporting or integrations, site visits, or routine O&M evidence extraction. 321ZERO does not provide independent verification, assurance or government approval of your figures — and White Glove does not automatically include those either. Independent assurance or specialist advice may require a separately appointed qualified professional. What we can do is organise your carbon and environmental evidence and prepare reporting material for your approval. Anything beyond the plans is scoped and priced before it starts. Product defects are always handled as normal support.
321ZERO is a calculation and reporting tool, not an audit or verification service. Engage a qualified environmental professional when independent assurance is required. Eco-Active Leader status still needs your own ISO/audit certification from an approved body.
