Supporting the UK’s net-zero objectives. An independent initiative; no government endorsement is claimed.
Start with understanding
Your footprint, made clearer.
Enter annual activity data from bills and travel records. This first version estimates selected energy and travel emissions; it is not a complete personal footprint or business inventory.
Enter your annual household energy use and personal travel.
Factors & calculation boundaries
Activity × factor ÷ 1,000 = tonnes CO₂e. UK Government 2026 revised flat file: electricity generated 0.13096 kg/kWh; natural gas (gross calorific value) 0.18231 kg/kWh; average car, unknown fuel 0.16591 kg/km; UK national rail 0.03092 kg/passenger km; short-haul flights to/from the UK, economy, including radiative forcing 0.12576 kg/passenger km. Flight selections use economy factors including radiative forcing: short-haul UK 0.12576; long-haul UK 0.11704; international non-UK 0.10916 kg/passenger km. Car selections: unknown 0.16591; petrol 0.16152; diesel 0.17265; non-plug-in hybrid 0.12961 kg/km. Include return flight distance. These are selected operational factors, not lifecycle totals.
Uses 2026 factors for UK activity. Choose the appropriate reporting year and activity categories for formal reporting. Construction, food, purchases, waste, water, refrigerants and upstream fuel emissions are excluded. Business results group gas and company-car travel in Scope 1, electricity in Scope 2, and selected travel in Scope 3; vehicle ownership and actual fuels must be confirmed for formal reporting.
Compare your entered footprint with a simple reduction scenario. These sliders reduce activity quantities; they do not predict equipment savings or claim avoided emissions from a project.
Rail remains unchanged. Replacement journeys and rebound effects are excluded. Compare like-for-like annual activity.

Turn understanding into action
Help build something that lasts.
Iam Zero Carbon Ltd intends to identify land and develop projects that reduce emissions, including homes designed for zero operational emissions. Our platform will offer a choice between supporting this development work and purchasing verified offsets.
Development concept
Homes for a lower-carbon future
Explore efficient buildings, clean energy and thoughtful materials. Funding could support land evaluation, feasibility, design and delivery.
No site, planning consent, budget or carbon-credit eligibility is confirmed in this prototype.Transparency first
See where support goes
Each future project page should show milestones, funding targets, expenditure, carbon measurement and progress reports.
Contributions would support development. They would not automatically buy verified credits or shares.Supplier to be selected
Choose verified offsets
A separate route for credits from eligible external projects—or our own projects if they qualify and issue credits.
Project identity, certification, vintage, price and retirement evidence must be available before purchase.
Our ambition is to create a defined route for qualifying supporters to become shareholders in Iam Zero Carbon Ltd.
This is a concept under development. Any future conversion right would be separate from a carbon credit and set out in formal terms, including eligibility, valuation, timing and what happens if a project does not proceed.
Shares could carry dividend rights, but dividends depend on profits and a company decision. Returns and share value are not guaranteed; investment capital would be at risk.
No shares, conversion rights or investment subscriptions are offered through this prototype. Project payments would not grant ownership unless expressly covered by an approved agreement.
Clear answers
Know what your contribution means.
Does supporting a project offset my footprint?
No. A contribution funds development. An offset requires qualifying credits and their retirement; we will show these as different choices.
What does retiring a carbon credit mean?
A credit is permanently marked as used in its registry, preventing it from being resold or claimed again. Your actual emissions remain part of your footprint.
Will low-carbon homes automatically generate credits?
No. Eligibility depends on an accepted methodology, additionality, measurement and independent verification. Operational emissions and construction emissions must be considered separately.
