Planning → Decarbonisation helps you plan reductions with your inventory. It has four tabs: Budgets, Carbon price, Projects & MACC and Forecast. Client admins and methodology owners can change the plan; everyone else can read it.
Every price, cost, rate and budget on this page is entered by your organisation. EmitLedger ships no carbon prices, no cost data and no default discount rate, and never fills one in for you.
Budgets
A budget is an annual emissions allowance in t CO₂e for the whole organisation, one asset, or one country or region.
- Choose the Reporting year and click New budget.
- Enter the Name, the Budget (t CO₂e), what it Applies to and the Scopes.
- Save. Each budget card shows the Actual against the Budget, the Variance, Within budget or Over budget, and a cumulative chart of actual against budget.
Actuals use your organisation’s default GWP set and consolidation, like the dashboards. For the year in progress, Year to date compares the months that have ended with the same share of the annual budget (the budget spread evenly over twelve months). This even spread is a display convention, not a seasonal budget.
Carbon price exposure
A scheme is your own label for a carbon price that applies to some of your emissions, for example a national levy or an emissions trading scheme. EmitLedger does not decide which assets or scopes a regulation covers: you choose them.
- On Carbon price, click New scheme.
- Enter the Scheme name and Currency (a three-letter code; amounts are never converted), the Covered scopes and the Covered assets (or All assets).
- Under Prices, add one row per year with the Price per t CO₂e, any Free allocation (t) and where the price comes from (Source).
For each year the table shows the Covered (t CO₂e) emissions, the price, the free allocation and the Exposure = (covered emissions − free allocation) × price. Past years use actual emissions; future years use the projection (see Forecast) and are marked Projection. A year without a price shows no exposure: earlier prices are never carried forward.
Projects and the MACC
An abatement project is a planned reduction with its cost.
- On Projects & MACC, click New project.
- Enter the Name, optionally the asset, the Status (Idea, Planned, Approved, In progress or Done), the Start year, Lifetime (years), Annual abatement (t CO₂e), Capex, Opex per year (negative for a net saving), the Currency and, if the project needs its own, a Discount rate (%).
The Cost per t CO₂e is (capex × capital recovery factor + opex per year) ÷ annual abatement. A project without its own discount rate uses the Default discount rate (%) you set on this tab; when neither is set it has no cost per tonne.
The Marginal abatement cost curve sorts projects from cheapest to most expensive per tonne: each bar’s width is the annual abatement and its height the cost per tonne. Projects in another currency, or without a discount rate, are listed under Not on the curve.
CO2 capture and transfer (CCUS) projects. Tick CO2 capture and transfer (CCUS) on a project with an asset, then use Actuals in its row: each reporting year from the start year shows the planned annual abatement next to the CO2 the asset actually transferred, as recorded in CO2 transfers. The current year is the year to date.
Forecast
The forecast is a projection, not a measured or calculated inventory value. It extends your past actuals with a simple statistical method and your own planning inputs; it is not a prediction and it is not reported as emissions.
- Method: Linear trend (a straight line through the history years) or Flat baseline (the average of the history years). Projected values never go below zero.
- History: how many complete past reporting years the method uses. Years that are not complete are shown as actuals but not used for the trend.
- Horizon: the last year projected. Automatic uses your latest target year, or a few years ahead when there is no target.
- With projects subtracts the annual abatement of projects that are Planned, Approved or In progress, from their start year for their lifetime. Done projects are already in your actuals and Ideas are not committed, so both are left out.
The chart also shows your targets as pathways and your budgets, so you can see whether planned projects close the gap. Every projected value on the page, including future exposure on Carbon price, is labelled as a projection.
Good to know
- Planning never changes inventory results, reports or targets.
- A scoped member sees actuals for the assets they can access only.
- Changes to budgets, schemes and projects are recorded in the audit log.
