Free Carbon Footprint Calculator (Scopes 1 and 2): measure in hours, not weeks

Measuring your carbon footprint is becoming a mandatory requirement for many companies in Spain following the publication of the Carbon Footprint Royal Decree. This decree establishes the need to calculate and report Scope 1 and 2 emissions, and soon Scope 3 as well.

However, many organizations face technical and time barriers when implementing these calculations using complex methodologies and tools, delaying compliance and their corporate climate strategy.

In this guide, you’ll learn:
What Scopes 1 and 2 are
How to calculate them according to regulations
Limitations of the official MITECO calculator

Why measuring and automating your footprint is a competitive advantage

What is Scope 1 and 2 carbon footprint?

A corporate carbon footprint measures the amount of greenhouse gases (GHGs) emitted by a company’s activities, expressed in tonnes of CO₂ equivalent. It is organized into three scopes:

Scope 1 (direct emissions):
Direct emissions from sources owned or controlled by the company. For example: combustion of natural gas in company boilers, diesel consumption by company vehicles, or refrigerant leaks from HVAC systems.

Scope 2 (indirect emissions from purchased energy):
Emissions from the generation of electricity, steam, heating, or cooling purchased and consumed by the company.

Scope 3 (other indirect emissions):
Emissions across the entire value chain, such as business travel, employee commuting, purchased goods, transportation and distribution, use of sold products, etc.

Why is calculating Scope 1 and 2 mandatory?

The Carbon Footprint Royal Decree require companies to:
- Calculate Scopes 1 and 2 as a minimum compliance requirement
- Publish them on their corporate website
- Establish an emissions reduction plan

Regulatory trends in Europe and Spain aim to align climate reporting with standards such as CSRD and the EU Green Taxonomy Regulation.

Official MITECO Carbon Footprint Calculator

The Ministry for Ecological Transition and Demographic Challenge (MITECO) provides an Excel-based carbon footprint calculator for organizations to record their emissions in the voluntary or mandatory registry.

✅ Advantages:

• Free and official
• Includes updated emission factors
• Allows calculation of Scopes 1, 2, and 3

❌ Limitations:

• Complex structure if you lack carbon footprint calculation experience
• Not intuitive, with multiple tabs and fields
• Requires prior training in carbon footprint and environmental management
• Doesn’t automate integration with other reports or reuse data

Our free carbon footprint calculator (Scopes 1 and 2)

At Dcycle, we’ve developed an Excel-based carbon footprint calculator optimized for Scopes 1 and 2, allowing you to:

- Calculate emissions quickly
- Enter consumption data and get emissions automatically
- Visualize results clearly
- Download and share it with your team at no cost

What does our calculator include?

✔️ Simple instructions tab so anyone on your team can use it
✔️ Consumption tables organized by emission type (fuels, electricity, refrigerant gases)
✔️ Automatic result cells in kgCO₂e and tonnes CO₂e
✔️ Updated emission factors (based on GHG Protocol methodology and MITECO sources)
✔️ Intuitive design ready to use without prior training

Why is it important to automate your carbon footprint?

While Excel is a great first step, many companies quickly discover that:

❌ It’s hard to consolidate data from different sites and departments
❌ Data can’t be reused in CSRD, Taxonomy, ESG reports, or product footprints
❌ It requires many hours of manual work and error checking
❌ It creates compliance risks if calculations aren’t consistent

🚀 With Dcycle you can:
✅ Automate your carbon footprint calculations (Scopes 1, 2, and 3)
✅ Reuse data for any report, audit, or tender
