GHG Accounting Course: What a Good One Teaches, Week by Week
What a good GHG accounting course teaches: Scope 1, 2 and 3 to the GHG Protocol, a four-week syllabus, free resources, and a checklist before you enrol.
In brief
- A good GHG accounting course teaches you to build a full Scope 1, 2 and 3 inventory to the GHG Protocol, on real data, not just to define the three scopes.
- The core skills fit in about four weeks part-time: boundaries, Scope 1 and 2 (location- and market-based), a Scope 3 screening, then a base year and target.
- The standards and the emission factors are free. What you pay for is practice on a messy dataset and feedback on your numbers.
- Before you enrol anywhere, check that the course uses a spreadsheet you keep, covers market-based Scope 2, and has you calculate Scope 3, not just read about it.
Search for a GHG accounting course and you will find two kinds: long certificate programmes with a lot of theory, and short videos that explain the three scopes and stop. Neither leaves most people able to do what employers and clients actually ask for, which is to take a year of bills, fuel records and purchase ledgers and turn them into an inventory that someone else can check. This article sets out what a course should teach, week by week, so you can judge any course, including ours.
The skills an employer or client expects
| Skill | What it looks like in practice |
|---|---|
| Set the boundary | Decide which sites, vehicles and subsidiaries are in, using operational or financial control, and write it down |
| Scope 1 | Convert gas, fuel and refrigerant top-ups into tonnes CO₂e with the right factor year |
| Scope 2, both ways | Report location-based and market-based electricity, and know when a renewable tariff counts |
| Scope 3 screening | Estimate all 15 categories from spend data, then improve the two or three that matter most |
| Base year and target | Choose a base year, set a recalculation policy and a reduction target |
| Explain the result | Write a one-page method note that a customer, auditor or tender panel can follow |
If a course syllabus does not mention market-based Scope 2 or a recalculation policy, it is probably an introduction rather than training you can use at work. Our explainers on the GHG Protocol and location-based vs market-based Scope 2 cover the background.
A four-week syllabus
| Week | Topic | Output |
|---|---|---|
| 1 | Boundaries, scopes and the GHG Protocol Corporate Standard | A boundary note for your practice organisation |
| 2 | Scope 1 and 2: fuels, refrigerants, location- and market-based electricity | Scope 1 and 2 totals with the factor sources listed |
| 3 | Scope 3: spend-based screening, then activity data where it matters | A 15-category screening and two detailed categories |
| 4 | Base year, targets and reporting | A finished inventory and a one-page method note |
At four to five hours a week, that is a realistic pace for someone working full-time. Faster courses usually skip the Scope 3 practice, which is where most of the work, and most of the mistakes, are.
What you can learn for free
You do not need to pay for the rules. The GHG Protocol standards are free to download, the UK Government publishes its conversion factors every June, and the US EPA publishes spend-based factors for Scope 3 screening. Our step-by-step footprint guide works through a full Scope 1 and 2 example with real factors, and the free GHG inventory template gives you the spreadsheet structure.
The GHG Protocol also runs its own paid e-learning on the Corporate and Scope 3 Standards, with a certificate. It is the authoritative source on the standards themselves; check its current price and format on the GHG Protocol website.
What is worth paying for
| Question to ask | Why it matters |
|---|---|
| Do I work on a real, messy dataset? | Clean textbook numbers teach the formula, not the judgement |
| Does someone check my numbers? | Feedback is the difference between a course and a video |
| Do I keep the workbook? | You will reuse it for your first real inventory |
| Is market-based Scope 2 covered? | Customers and SBTi targets ask for it |
| Do I calculate Scope 3, or just read about it? | Scope 3 is usually the largest part and the hardest |
| Which factor sets are used? | You should learn to choose a factor year, not just copy one |
A certificate on its own carries little weight with most small and medium employers. A finished inventory you can show, with a clear method note, carries a lot.
Frequently asked questions
How long does it take to learn GHG accounting?
The core of Scope 1, 2 and 3 inventories fits into about four weeks at four to five hours a week. Becoming confident on complex Scope 3 categories takes several real projects.
Do I need a certificate to work in carbon accounting?
Not usually. Employers and clients look for evidence you can build an inventory: a worked example, a method note, and knowledge of the GHG Protocol and the factor sets.
Can I learn GHG accounting in Excel?
Yes. Most small and medium inventories are built in a spreadsheet. Software helps at scale, but you should understand the calculations first.
What is the difference between carbon accounting and GHG accounting?
In practice they mean the same thing: measuring an organisation’s greenhouse gas emissions, usually to the GHG Protocol, in tonnes of CO₂ equivalent.
Is the GHG Protocol free?
Yes. The standards and guidance are free to download from the GHG Protocol website. Its training courses are paid.
