What EmitLedger does
EmitLedger calculates, checks and reports the direct (Scope 1) and purchased-energy (Scope 2) greenhouse gas emissions of oil and gas assets: turbines, engines, heaters and diesel, flaring, venting, fugitive leaks, and purchased electricity or heat. Every number stays traceable from the meter reading to the report.
The work follows four steps:
- Set up your organisation and its assets from engineering templates: systems, emission sources and their data streams (meters). See Setting up assets.
- Get data in with generated Excel templates, your own spreadsheets (mapping wizard) or forms. Everything is validated before it is saved. See Excel import.
- Calculate: each source is calculated gas by gas with a versioned method and factors from a pinned library release. See How calculations work.
- Govern and report: each asset and month is submitted, reviewed, approved and locked; dashboards, compliance checks and reports all use the same numbers. See Reporting periods.
Three words appear everywhere:
- Organisation: your company’s own space. Its data is isolated from every other client in the database itself.
- Asset: a facility such as an FPSO, a platform or a gas plant. It contains systems (for example Power generation), each with emission sources (for example a gas turbine generator) and their data streams (for example fuel gas consumption in Sm³).
- Reporting period: one asset and one calendar month. Periods are what get submitted, approved and locked.
EmitLedger covers Scope 1 and Scope 2 only. Regulatory packs give indicative checks, not a regulatory opinion.
The screen
Every page has the same frame: a header with the Organisation selector, the search box, your name and Sign out; the sidebar on the left; and the page itself. Below a tablet width the sidebar becomes a slide-out menu: use Open menu at the top left. On a large screen the sidebar scrolls on its own, so Settings and Help stay within reach on long pages.
Overview and Explore sit at the top of the sidebar. The other pages are in groups. Click a group heading (or press Enter or Space on it) to open or close it; the number next to the heading is how many pages it holds. The group of the page you are on opens by itself, and the browser remembers which groups you left open.
| Sidebar entry | Pages | Use it to |
|---|---|---|
| (top) | Overview, Explore | See the headline results, then drill down from a month to a category, an asset, a source and its results |
| Dashboards | By country, Assets, Source categories, Flaring & venting, Methane, Energy, Data quality | Read results by country, asset and category, and check completeness and anomalies |
| Planning | Targets, Decarbonisation | Track reduction targets; plan budgets, carbon prices, abatement projects and forecasts |
| Data input | Excel import, Activity entry, Mapping wizard, Imports | Get data in from templates, forms or your own spreadsheets, and follow each import |
| Operational records | Events, Production, Compositions, Instruments, Inventories & LDAR, LDAR programme | Keep the operational records calculations use, and run the leak detection and repair programme |
| Governance | Periods, Restatements, Audit log | Approve and lock months, correct locked months, trace changes |
| Reporting & assurance | Reports, Compliance, Measurement reconciliation, Verification | Request reports, run pack checks, reconcile measured and calculated methane, work with verifiers |
| Setup | Hierarchy, Library, Onboarding wizard | Countries, assets, systems, sources, data streams and packs; the emission factor library; the guided first set-up |
| Settings | General, Members, API keys, Webhooks, Plan & usage, Support access | Organisation defaults, people, partner API keys and webhooks, plan and support access. One sidebar entry; the sections are tabs at the top of the settings pages |
| Help | Help centre, System status, Theme | These help pages, the public service status page, and light or dark colours |
Members, API keys and Webhooks are shown to client admins only, and Verification to the people taking part in a verification. Platform administrators also see Platform console.
Finding your way
- Every main screen has a Help link next to its title. It opens the part of these help pages that explains that screen.
- Menu items your role cannot use still open, but show a message such as “Your role cannot view the audit log.” instead of data. See Roles.
- Dashboard filters are kept in the page address, so a link you copy opens the same view for a colleague with access.
- Charts have a Show data table button with the same numbers as a table.
- Search at the top (or Ctrl+K, Cmd+K on a Mac) finds assets, sources, meters, imports, factors, periods, pages and help articles. See Search and the command palette.
- The application follows your computer’s light or dark setting; choose Light or Dark with Theme at the foot of the sidebar to override it.
- If you belong to several organisations, switch with the Organisation selector in the header.
