Activity data
Entities, sites, sources and monthly usage in one table. Scope 1 and 2 emissions come straight from what you enter.
Same as a spreadsheet: Name box and formula bar, drag to select a range, copy and paste across cells, Ctrl+Z to undo and Ctrl+Y to redo, F2 to edit, arrow keys, Tab and Enter to move, Delete to clear, count, sum and average of the selection, drag column widths and row heights, reorder columns, freeze panes. Column order, width and freeze are saved per person.
Year is a row, not a column. Several years sit in one table so last year and this year read side by side, and you filter the year column when that is too much.
Only the factor edition is recorded. With the same GWP, heating-value revision and grid vintage, recalculating years later gives the same number.
If the fuel is unset or no factor applies, we write the reason. Filling in zero makes the total quietly smaller.
Screenshots of the product as it runs. Not mockups.
Entity, site and source stay pinned on the left while usage runs January to December on the right. The emissions cell opens the twelve months behind it.
Pick values in the column header to see only the sites or sources you want. The filter lives in the URL, so the view is shareable.
Select and paste like a spreadsheet. Count, sum and average of the selection appear below.
Open one cell to see which file and which cell the value came from, and who changed it from what to what, and when.
Activity data, member changes and operator actions in time order. Usage is overwritten, so without this the previous value is gone.

Keep only the factors this calculation needs
Keep the factors you picked in your workspace. We do not copy the value, so when the source is revised your list follows.
My factorsFind factors
Public-source emission factors, values included
Factors from sources that allow redistribution, EPD Korea, US EPA, the Korean Ministry of Environment and others, with their values. Editions of the same product sit side by side.

Ask, and the evidence comes with the answer
Type a material name or a usage figure and we find candidates in public sources. Attach a spreadsheet, PDF or image and we build the import draft.

One spreadsheet creates the sources too
We read the entity, site and energy source written in the file and propose them row by row. Sources that do not exist yet are created when you commit.

Everything below behaves exactly as it does in the app. Click around.
The twelve months open. Months with no reading and months that have not happened yet are shown differently. Click a month and its calculation appears on the right.

Only where the name alone is not enough. Try it — nothing opens on its own.
The usage figures and the factor they are multiplied by are examples. The folding and the drawing are the product's own code — choosing which factor to use happens in the app.
