What Is
Carbon Accounting, Really?
A guide for SME owners hearing about carbon emissions reporting obligations for the first time. The short answer: it depends what you're trying to do — but for most companies in Romania, the first step is far simpler than it sounds.
What is a carbon footprint and how does it relate to carbon accounting
The two terms are often confused, so let's clarify them from the first sentence.
Carbon footprint is the total quantity of greenhouse gases — expressed in tonnes of CO₂ equivalent (tCO₂e) — generated directly or indirectly by an activity: a person's, a product's, or a company's.
Carbon accounting is the process by which you measure, calculate and document that footprint, in a structured and repeatable way — just as a financial accountant tracks a company's expenses.
In other words: the carbon footprint is the result (the final number, in tonnes of CO₂e). Carbon accounting is the method that gets you there. When a client or a bank asks you for "emissions data" or your "company's carbon footprint," what they're really asking for is the output of a carbon accounting process — Scope 1, Scope 2, possibly Scope 3.
The rest of this guide explains exactly what that process looks like, step by step, for a small or medium company in Romania.
Why this question matters now, in 2026
Until a few years ago, carbon accounting was a topic for large corporations, multinational sustainability departments and voluntary reports. In 2026, that has changed fundamentally.
The CSRD Directive extended the reporting obligation to companies with more than 50 employees or turnover above RON 50 million. The CBAM mechanism introduced an obligation to declare embedded emissions in products imported from non-EU countries. Large customers — Kaufland, Lidl, IKEA, Bosch — are already requesting emissions data from their small suppliers.
The result: hundreds of thousands of SMEs across Europe suddenly find themselves facing a requirement they've never encountered before. The first reaction is usually panic — but it isn't warranted.
Carbon footprint legislation in Romania: CSRD, CBAM and the reporting obligation
Concretely, in Romania, two European mechanisms generate carbon footprint obligations:
CSRD/ESRS — an estimated 5,300 companies in Romania will fall, directly or indirectly (through pressure from large reporting clients), under CSRD obligations. The specific standard for carbon emissions is ESRS E1. Companies that don't fall directly under CSRD but supply companies that do are increasingly receiving data requests under the simplified VSME standard — essentially a lighter reporting format designed specifically for SMEs.
CBAM — applies to importers of cement, steel, aluminium, fertilisers, hydrogen and electricity from outside the EU. The cost of CBAM certificates rises progressively: 2.5% of the total obligation value in 2026, climbing gradually to 100% by 2034. The first CBAM certificates must be purchased starting February 2027, and the deadline for the first annual declaration is 30 September 2027 — but emissions data must be collected from suppliers starting in 2026; it can't be reconstructed overnight later.
In practice, if you're an SME in Romania in 2026, you exist somewhere on this spectrum: either you report directly, or you're under commercial pressure to report by a client or a bank. Very few companies remain entirely outside this conversation.
What carbon accounting actually is — no jargon
Carbon accounting is, at its core, the answer to a single question: how much CO₂ (and other greenhouse gases) does your company's activity produce in a year?
That's it. Everything else — Scope 1, Scope 2, Scope 3, GHG Protocol, emission factors — are technical tools to answer that question more precisely. But the question itself is simple.
Think of it this way: a financial accountant needs to know how much your company spent, and on what. A carbon accountant needs to know how much your company polluted, and where that pollution came from. Just as expenses are split into categories (salaries, rent, raw materials), emissions are split into categories — called Scopes.
The three Scopes explained simply
Scope 1 — What you produce directly
Fuel combustion in your own machinery, trucks or boilers, plus chemical process emissions. If you have a company vehicle fleet or your own heating plant — that's Scope 1.
Scope 2 — The electricity you buy
Electricity consumed at your factory, warehouse or offices. You don't produce it, but by consuming it you carry indirect responsibility. Simple to calculate: consumption (kWh) × the national grid emission factor — for Romania, approximately 0.265 kg CO₂/kWh.
Scope 3 — Everything moving around you
Raw material transport, employee travel, packaging, waste, supplier emissions. The most complex and often the largest — sometimes over 90% of total footprint. But for initial reporting, you don't need to calculate all of it at once.
How hard is it really — what the data says
Here are two real studies that contradict common intuition:
OECD study (2025): a UK survey found that 8 out of 12 SMEs managed to collect the necessary data and complete a carbon report in a maximum of 8 hours, covering 2-3 emission categories. Eight hours. One working day.
World Economic Forum study (2026): 50% of European SMEs already communicate carbon footprint data to customers — even without a legal obligation to do so.
What this means in practice: you probably already have most of the data you need. Electricity bills, fuel receipts, your fleet's mileage, invoices from key suppliers. Carbon accounting doesn't invent new data — it organises existing data into a standard format.
How to calculate your carbon footprint — the formula, step by step
The basic formula, for Scope 1 and Scope 2, is always the same:
Here's what it looks like concretely for a distribution company with 30 employees, a 1,000 m² warehouse and a fleet of 5 vehicles.
- Step 1 — Collect the data (2-3 hours) — Pull electricity invoices for the last 12 months, fuel receipts for the fleet, and natural gas or pellet invoices for heating. With these three categories, you've solved 80% of Scope 1 and Scope 2.
- Step 2 — Apply the emission factors (30 minutes) — 2026 examples: Romania's national grid electricity ~0.265 kg CO₂/kWh, diesel ~2.68 kg CO₂/litre, natural gas ~2.04 kg CO₂/m³ (DEFRA 2024).
- Step 3 — Calculate and document (1-2 hours) — Multiply consumption by the emission factor, get emissions in tonnes of CO₂ equivalent, document your data sources and generate the report.
Total effort for a straightforward company: 4-6 hours for the first report. Half a working day, with the help of a digital tool. If you're an importer with dozens of suppliers across Asia and products across 50 different customs codes, complexity increases significantly — but the average Romanian distribution or manufacturing company isn't in that situation.

Where it genuinely gets complicated — let's be honest
I don't want to downplay this. There are situations where carbon accounting really is difficult:
Full Scope 3
If you need to report emissions across your supply chain — how much CO₂ your supplier produced to make what they sell you — you enter a different complexity category. Small suppliers often don't have this data; sometimes you must use estimates or industry averages.
Products with a complex life cycle (LCA)
If you want to know exactly how much CO₂ a product contains — from raw material to end of life — you need a full LCA study (ISO 14040/14044). Genuinely technical, requires specialised software, typically 4-6 weeks of work.
Third-party verification
If your report must be audited by an accredited body — required for EPDs (EN 15804+A2) or some CSRD requirements — the process adds a level of rigour and documentation that takes more effort.
Lack of historical data
If your company hasn't tracked energy and fuel consumption over past years, the first reporting year will require more reconstruction effort.
The mistake most SMEs make
Most often, the entrepreneurs I meet make one of these two mistakes:
Mistake 1 — Waiting until they "have to." The first reporting year is the hardest — not because the process is complicated, but because you lack experience and your data isn't organised. The second year is twice as fast. The third is nearly automatic. Companies starting now have a huge advantage over those forced to start in 2027.
Mistake 2 — Believing they need an expensive consultant. Basic carbon accounting — Scope 1 and Scope 2 — doesn't require a specialised consultant. It requires a good digital tool and 4-6 hours of work. Consulting becomes necessary once things get complex: detailed Scope 3, product LCAs, official EPDs, CBAM for imports. Not before.
What changed in 2026 — and why it matters now
In the past, carbon accounting was voluntary — companies did it for image, or because large investors asked for it. In 2026, it became mandatory for a growing segment of companies and, more importantly, became a commercial requirement.
Kaufland Romania announced it will request emissions data from its suppliers starting 2025-2026. European banks increasingly condition financing on proof of a sustainability profile. Customers in Germany, Austria, the Netherlands — important export markets for Romania — include carbon criteria in their tender specifications.
In other words, even if your company isn't legally required to report, it may become commercially required to. Your most important client can become your de facto "auditor."
Carbon footprint and ESG reporting — how they connect
If you've heard the term ESG (Environmental, Social, Governance) and wonder where all of this fits — the answer is simple: carbon footprint and carbon accounting are part of the "E" (Environmental) pillar of ESG. CSRD is the European legal framework that makes the environmental component of ESG mandatory to report, and ESRS E1 is the specific technical standard for climate change and emissions.
In practice: if a client, bank or investment fund asks you for "ESG data" or a "sustainability report," the emissions component of that report is exactly what you calculated above. It isn't a separate process — it's the same carbon accounting, in a format investors request.
A moment of honesty — why I built CarbonDRI
I work in Suceava, with small and medium companies in the North-East region. I've seen a furniture manufacturer lose a contract with a German client because it couldn't provide the emissions data required in the tender specifications. I've seen a construction materials importer who didn't know its products fell under CBAM and risked significant fines.
These weren't unprofessional companies — they were competent entrepreneurs with good products who simply had never come into contact with this requirement before.
I built CarbonDRI from a simple conviction: carbon accounting shouldn't be reserved for large corporations that can afford sustainability departments and consultants charging hundreds of euros an hour. An SME with 30 employees deserves the same access to clear tools and a simple process.
The practical takeaway — what to do if you're an SME owner in Romania in 2026
Don't know where to start?
Calculate Scope 1 and Scope 2 first. You need your electricity bills and fuel receipts for the last 12 months — nothing more. You can do this today, in a few hours, free at carbondri.ro.
Received a request from a client?
Identify exactly what's being asked for — a simple carbon footprint calculation, or a certified document (EPD, CSRD report). The difference is significant and involves different processes. Contact a specialist before promising anything to your client.
Importing products from outside the EU?
Check whether your products fall under CBAM — not all do. If they do, you need authorisation as a declarant and a system for collecting emissions data from suppliers. The first declaration deadline is September 2027, but data collection starts in 2026.
Supplying a large company?
Prepare for emissions data requests. The simplest approach: calculate your own footprint and keep the documentation. When the request comes, you'll already have the answer.
Frequently asked questions
Is a personal carbon footprint the same as a company's?
Not as a reporting process. A personal carbon footprint (transport, household consumption, diet) is calculated with different factors and a different purpose — individual awareness, not legal compliance. This guide and the CarbonDRI tool are designed for a company's carbon footprint (Scope 1, 2, 3), required by regulation or by clients.
Are carbon footprint and carbon accounting the same thing?
Almost. The carbon footprint is the result (the number, in tonnes of CO₂e). Carbon accounting is the process that gets you there. In practice, the terms are often used interchangeably.
Do I need a consultant to calculate my carbon footprint?
For Scope 1 and Scope 2, usually not — a digital tool and 4-6 hours of work are enough. A specialist becomes necessary for detailed Scope 3, LCA, EPDs, or CBAM for imports.
How do I know if my company must declare its carbon footprint?
Check whether you fall directly under CSRD (over 50 employees or turnover above RON 50 million), whether you import products subject to CBAM, or whether a large client or bank has already requested this data — the third case is, in 2026, the most common.
