ISO 14064 Training: Greenhouse Gas Accounting, Reporting and Verification

Opens with a customer asking for your company's emissions, and a self-rating on greenhouse gas accounting. Covers three developments: the UAE's Federal Decree-Law No. 11 of 2024, in force from 30 May 2025, with records kept at least five years; the EU Carbon Border Adjustment Mechanism moving into its definitive regime on 1 January 2026, covering cement; and the 29 July 2026 plan by the GHG Protocol and ISO to combine their corporate standards, while ISO 14064-1:2018 remains current. Turns them into four questions on users, boundary, method and checking. Introduces XYZ Cement, a Dubai cement maker with a quarry, coal-fired kiln and a 40% joint venture, clears four myths, and outlines the thirteen modules and exam. It ends with a recap and three practice questions.

What you will be able to do

• Explain why authorities, buyers and lenders ask for checkable emissions data
• Apply four questions to your organisation's emissions figures
• Describe how the course, worked calculations and final exam work

Why it matters

Knowing who will ask for your numbers, and why, shows what your inventory must be able to stand up to.

Starts with a chiller at XYZ Cement topped up with 120 kilograms of HFC-134a, just 0.12 tonnes by weight but far larger once converted. Covers converting every gas to CO2e by multiplying its mass by its GWP, using the latest IPCC values over 100 years, stated in the report. Explains the ISO 14064 series within the ISO 14060 family: Part 1 for organisations, Part 2 for projects, and Part 3 for verification and validation. Covers the five principles that guide every requirement, and how ISO 14064-1 and the GHG Protocol are aligned, with the four other indirect categories falling within Scope 3 but not one for one, so each source is mapped explicitly. Ends with a test of whether all sites and the base year use the same GWPs. It ends with a recap and three practice questions.

What you will be able to do

• Convert a greenhouse gas to CO2e using its GWP
• Describe the three parts of the ISO 14064 series
• Map ISO 14064-1 categories to GHG Protocol scopes

Why it matters

Stating GWPs and mapping categories clearly lets your totals be compared across sites, years and frameworks.

Opens with XYZ Cement's ready-mix joint venture, 40% owned and run by its partner, left out one year and added the next, so the total jumps for no real reason. Covers defining organisational boundaries: every facility, with who owns it and who runs it. Explains consolidating by one approach, financial control, operational control or equity share, consistent with the intended use, and following substance over form as the annex asks. Shows the GHG Protocol Corporate Standard's table based on financial accounting categories, and XYZ's boundary record, a map of the group's entities and copies of agreements. Ends with checking your latest financial statements against your boundary record so every entity is in or out with a written reason. It ends with a recap and three practice questions.

What you will be able to do

• Choose a consolidation approach for organisational boundaries
• Apply control or equity share to a joint venture
• Keep a boundary record for every facility in or out

Why it matters

Deciding and recording the boundary first stops totals moving because of what was counted rather than what changed.

Practice: Practice: Organisational boundaries · 3 questions

Starts with XYZ Cement's first draft inventory of three lines, the kiln, the quarry fleet and the electricity bill, until a European buyer asks about imported coal shipping, paper bags and delivery trucks. Covers the reporting boundary: emissions from within the organisational boundary, plus the significant indirect emissions, documented. Explains aggregation into six categories, with direct emissions reported gas by gas, and places each of XYZ's sources in one category and subcategory. Shows a source register with one line per source, showing facility, category, subcategory and gases. Ends with checking fleet and lease agreements and freight invoices so overlaps are written down and nothing is counted twice. It ends with a recap and three practice questions.

What you will be able to do

• Define a reporting boundary that includes significant indirect emissions
• Place each source in the right ISO 14064-1 category
• Keep a source register that prevents double counting

Why it matters

A clear category for every source means a buyer's questions about your value chain already have an answer.

Practice: Practice: Reporting boundaries and emission categories · 3 questions

Opens with XYZ Cement's team dropping coal mining and preparation emissions because the data were hard to get, without recording why, and a verifier who cannot tell if the source was small or inconvenient. Covers identifying and documenting all relevant sources, sinks and gases by category. Explains the logic of clause 5.2.3: setting your own significance criteria in advance for the intended use, approved and dated before the screening results, and never using them to exclude substantial quantities. Shows screening the value chain by mapping every category and subcategory, quantifying and reporting significant indirect emissions, justifying every exclusion, and running the screening again when the business changes. It ends with a recap and three practice questions.

What you will be able to do

• Identify and document all relevant sources, sinks and gases
• Set significance criteria in advance and apply them to indirect emissions
• Justify every exclusion in writing

Why it matters

Criteria set before the results let you show a verifier that nothing large was left out for convenience.

Practice: Practice: Sources, sinks and significant emissions · 3 questions

Starts with the coal that fires XYZ Cement's kiln, where adding up coal ordered and using a website factor gives a figure nobody can repeat, against measuring coal actually burnt. Covers choosing methods that minimise uncertainty and give reproducible results, and documenting the approach, data and model. Explains the one-line calculation: activity data times emission factor times GWP gives tonnes of CO2e. Works through XYZ Cement's direct emissions on screen, showing that the rock, the chemistry of making clinker, is a larger source than the fuel, for a total of 998,949 tonnes of CO2e. Shows a calculation file per source, one register of factors, and raw data kept: weigher logs, invoices, lab results and calibration records. It ends with a recap and three practice questions.

What you will be able to do

• Calculate emissions from activity data, emission factors and GWP
• Explain why clinker process emissions exceed fuel emissions at a cement plant
• Keep calculation files and a factor register that make results reproducible

Why it matters

A method a colleague can repeat to the tonne is what makes your emissions figure defensible.

Opens with XYZ Cement buying renewable energy certificates for 30,000 megawatt hours in 2025, and marketing wanting to subtract them from Category 2. Covers Annex E: imported electricity quantified on the location basis with the factor that most closely fits the grid, giving the Category 2 figure. Explains how contractual instruments that meet the quality criteria give a market-based result, reported separately and never subtracted, and what a unique claim means. Works through XYZ's transport and purchased products in the value chain with the strongest data available, recording each factor's source and checking that supplier factors stop at the supplier's gate. Ends with XYZ's total of 1,094,349 tonnes of CO2e. It ends with a recap and three practice questions.

What you will be able to do

• Quantify purchased electricity on the location basis
• Report certificates as a separate market-based result
• Calculate value-chain emissions with named factor sources

Why it matters

Keeping grid emissions and contracts on separate lines avoids a claim that buyers and verifiers will reject.

Practice: Practice: Purchased electricity and the value chain · 3 questions

Starts with a verifier asking XYZ Cement how accurate its total is, and a team that has a figure to the tonne but no idea how reliable each input is, which is false precision. Covers GHG information management procedures: owners for each data stream, such as the maintenance manager for diesel and refrigerant, checks, internal audits and archives, including the GWPs used. Shows an internal check that traced a figure from the draft report to the workbook and back to the weigher log, finding a March coal double entry that was corrected. Explains retaining records to enable verification, assessing uncertainty for data and models by category, and how XYZ's analysis showed which input to improve, with an improvement plan checked year on year. It ends with a recap and three practice questions.

What you will be able to do

• Set up GHG information management with owners, checks and audits
• Retain records that let a verifier follow every figure
• Assess uncertainty by category and use it to choose improvements

Why it matters

Knowing where your uncertainty lies tells you which data to improve first, instead of polishing the wrong number.

Opens with XYZ Cement buying a cement grinding plant in Mumbai in 2026 that emitted about 40,000 tonnes of CO2e in 2025, making emissions appear to rise by about 3.7% against the base year. Covers choosing a base year with verifiable data for the current boundary, here calendar year 2025, explaining it and building a full inventory for it. Explains recalculating for structural changes, new methods or factors and substantial errors, never for changes in production, with XYZ's recalculation log and a cumulative 3% threshold. Covers reporting reduction initiatives separately, with about 49,600 tonnes of CO2e tracked per tonne of cement at the Dubai plant, listing offsets apart without netting them off, and keeping biogenic carbon dioxide in its own line. It ends with a recap and three practice questions.

What you will be able to do

• Choose and explain a base year with verifiable data
• Recalculate the base year for structural changes and errors
• Report reductions, offsets and biogenic CO2 separately

Why it matters

Comparing like with like means your reported trend reflects real performance, not acquisitions or method changes.

Starts with a company that publishes a smart emissions summary claiming to follow ISO 14064-1, with no base year, uncertainty, GWPs or verification status, so the claim does not hold under clause 9.1. Covers when a report shall be prepared: if the inventory is verified or conformity is claimed in public, and that it must be complete, consistent, accurate, relevant and transparent. Explains planning the report: purpose, users, responsibilities, frequency, format, content and dissemination. Walks through XYZ Cement's report chapter by chapter, for calendar year 2025, covering all twenty required items from the description of the organisation to the GWPs and their source. Ends with a reader test by someone from finance or procurement. It ends with a recap and three practice questions.

What you will be able to do

• Decide when ISO 14064-1 requires a GHG report
• Plan a report's purpose, users, format and content
• Check that a report contains all twenty required items

Why it matters

A report that contains every required item is the only basis for claiming conformity in public.

Practice: Practice: The GHG report · 3 questions

Opens with XYZ Cement's plan for a waste heat recovery unit that a supplier's brochure says saves 30,000 tonnes of CO2e a year, and the question: saves compared with what? Covers how Part 2 shares the five principles of Part 1, and defining the baseline scenario as the most likely case without the project, quantified conservatively with functional equivalence. Explains the reduction as the baseline minus the project for each gas and source, and why it must be additional. Covers the monitoring plan, data quality procedures, and the GHG report made available to intended users under clause 6.13, verified under ISO 14064-3 if requested. Ends with three checks a validator would make. It ends with a recap and three practice questions.

What you will be able to do

• Define a conservative baseline scenario for a GHG project
• Calculate a project's emission reduction for each gas and source
• Set up a monitoring plan that supports a credible claim

Why it matters

A reduction measured against a defined baseline is one others can rely on, and perhaps buy as a credit.

Practice: Practice: GHG projects under ISO 14064-2 · 3 questions

Starts with a European buyer asking for XYZ Cement's 2025 inventory to be verified, with files on three laptops and unnamed factors in one version, and an organised evidence pack in the other. Covers the difference between verification of historical statements and validation of assumptions about the future. Explains agreeing the type, objectives, criteria, here ISO 14064-1:2018 for calendar year 2025, scope, level of assurance and materiality before the work starts, and a limited assurance conclusion in negative form. Covers planning, evidence gathering, data trails, the independent review, and opinions that are unmodified, modified, adverse or disclaimed. Shows the verifier finding the March coal double entry already corrected and logged. It ends with a recap and three practice questions.

What you will be able to do

• Tell verification from validation
• Agree criteria, assurance level and materiality with a verifier
• Prepare evidence trails that a verifier can follow without help

Why it matters

Building the evidence trail before the verifier arrives saves weeks of questions and a weaker opinion.

Practice: Practice: Verification under ISO 14064-3 · 3 questions

Opens with the question of whether the work is done once an inventory is verified. Runs XYZ Cement's whole case step by step: the purpose, set by the UAE authority and European buyers; operational control, with the ready-mix venture out and its reason recorded; the source register and significance criteria; quantification with a factor register naming the IPCC equation; electricity and the value chain; the data trail from weigher log to report with the corrected double entry; the base year, the report and an unmodified opinion. Then covers using a verified inventory for targets specified as clause 7.3 asks, for reduction plans and answering requests from one data set, the revision under way, a road map, and the final exam.

What you will be able to do

• Follow an inventory from first request to verified opinion
• Use a verified inventory to set targets as clause 7.3 asks
• Keep data by source, gas and facility ready for future rules

Why it matters

Seeing every decision in one case helps you build an inventory that is used, not just verified.
