What is emissions tracking software and why do companies need it?

Definition and core functions

Emissions tracking software is a solution that helps companies collect, calculate, and report their greenhouse gas emissions under the GHG Protocol across three scopes:

Scope 1: Direct emissions from owned or controlled sources, including company vehicles, heating systems, and production processes.

Scope 2: Indirect emissions from the consumption of purchased energy, particularly electricity, heat, and steam.

Scope 3: All other indirect emissions in the upstream and downstream value chain: purchased goods and services, business travel, employee commuting, transport, waste disposal, and more. The 15 Scope 3 categories account for more than 70% of the total carbon footprint at most companies.

Why emissions tracking is strategically important today

The pressure on companies to track their emissions systematically comes from multiple directions simultaneously:

Regulatory: CSRD requires thousands of European companies to produce detailed GHG inventories under ESRS E1, including Scope 3 emissions and climate target planning. The German Supply Chain Act (LkSG) is raising transparency requirements across the supply chain.

Strategic: Companies pursuing Science Based Targets (SBTi) need precise and consistent emissions data as the foundation for reduction pathways and progress measurement.

Commercial: Customers and investors are increasingly asking for verified emissions data. Supply chain transparency is becoming a competitive advantage.

5 criteria for choosing the best emissions tracking software

1) Complete Scope 3 coverage across all 15 categories

The most important technical criterion is full coverage of all 15 Scope 3 categories under the GHG Protocol. Many platforms only support the most common categories (1, 3, 6, 11). Make sure the software covers the specific categories relevant to your company methodologically correctly: Category 4 (Upstream Transportation) for logistics companies, or Category 15 (Investments) for financial institutions.

2) Methodological rigour and auditability

Emissions tracking software must not just deliver numbers, but auditable calculations with complete documentation: which emissions factors were used, from which data source, under which methodology, and in which version. This is not only relevant for external assurance under CSRD but also for internal quality assurance and comparability across reporting periods.

3) Data integration and degree of automation

Manual data entry is the biggest weakness in emissions tracking. A good platform offers native connectors to ERP, accounting, procurement, and HR systems and loads activity data automatically from source systems. This significantly reduces manual effort and improves data quality by eliminating manual transcription errors.

4) Regulatory compatibility with CSRD and ESRS E1

For European companies, CSRD compatibility is not an optional feature but a requirement. The platform must cover the specific disclosure requirements of ESRS E1: GHG accounting, climate transition plans, climate targets, and progress measurement. Check whether the software offers specific ESRS E1 templates and validation rules, or whether you need to manually prepare report data afterwards.

5) Scalability and future-proofing

Regulatory requirements for emissions reporting will continue to grow: Scope 3 data obligations will increase, assurance requirements will rise, and SBTi targets will be increasingly demanded by business partners. Choose a platform that scales with these requirements and is regularly updated: new emissions factor databases, new regulatory templates, and technical support on methodological questions.

How to implement emissions tracking software

Step 1: Define system boundaries and materiality

Before producing the first emissions inventory, system boundaries must be clearly defined: which subsidiaries, sites, and activities are included? Which Scope 3 categories are material for the company? A materiality assessment helps concentrate the effort on the relevant emissions sources.

Step 2: Analyse data availability

The biggest obstacle in emissions tracking is often not the software, but data availability. Create an overview of all relevant activity data: energy bills, fuel consumption, procurement volumes, business travel data, logistics data. Identify which data can be automatically extracted from source systems and where manual collection is necessary.

Step 3: Establish emissions factors and methodology

Consistent methodology is the key to comparable emissions data across multiple years. Decide which emissions factor database will be used (DEFRA, ADEME, ecoinvent, or supplier-specific primary data) and which calculation methodology applies to Scope 2 (location-based or market-based). Document these decisions for the subsequent audit.

Step 4: Define the base year and climate targets

Emissions tracking without target-setting is only half the job. After the first complete inventory, define a base year and set measurable climate targets: absolute reduction targets, intensity targets, or SBTi-aligned pathways. The software should automatically calculate and visualise progress against these targets.

5 benefits of modern emissions tracking software

1) Complete and consistent carbon inventory

A specialised platform ensures that all relevant emissions sources are systematically collected and calculated under a unified methodology. This eliminates the most common errors in manual carbon inventories: missing categories, inconsistent emissions factors, and undocumented methodology.

2) Significant time savings through automation

Automated data collection from source systems reduces the annual effort for the carbon inventory from weeks to hours. Particularly for Scope 3 data collection across the supply chain, automation makes the difference between a comprehensive and an incomplete inventory.

3) Audit-ready documentation for CSRD and external auditors

External assurance under CSRD requires complete documentation of all emissions data: source references, emissions factors, calculation rules, and change history. A modern platform creates this documentation automatically, significantly reducing the effort for audit procedures.

4) Connection with CSRD, EU Taxonomy, and LkSG

Good emissions tracking software does not operate in isolation: emissions data collected for the carbon inventory should flow automatically into CSRD reports, EU Taxonomy analyses, and supply chain reports. This prevents duplicate work and consistency problems across different reporting obligations.

5) Foundation for strategic climate planning

Reliable emissions data is the prerequisite for a credible climate strategy. Only once Scope 1, 2, and 3 are fully captured can a company define its reduction pathway, prioritise measures, and measure progress over time, internally and for external stakeholders.

Dcycle: emissions tracking and regulatory reporting in one platform

From data management to CSRD reporting

Dcycle is designed as an integrated platform that connects emissions tracking with regulatory reporting, savings identification, and operational decisions. The carbon inventory companies produce today for their climate strategy becomes the foundation for the CSRD report under ESRS E1, EU Taxonomy compliance, and LkSG reporting.

Instead of running multiple systems in parallel, Dcycle centralises all emissions data in a single platform: automatically collected, methodologically correctly calculated, and prepared for regulatory output.

Scope 3 and supplier emissions

The most demanding part of emissions tracking is Scope 3. Dcycle helps companies systematically collect supplier emissions, integrate primary data from suppliers, and map the Scope 3 inventory across all 15 categories, compatible with GHG Protocol, SBTi, and CSRD.

Integration with the rest of sustainability reporting

Emissions data in Dcycle flows automatically into all further reporting requirements: CSRD reports, EU Taxonomy analyses, SBTi progress measurement, and supply chain reporting. This is the decisive difference from isolated carbon accounting tools that do not connect emissions data with the regulatory reporting context.
