From CO2 reporting to ESG strategy 

Corporate mobility data is often overlooked, but it could be key to unlocking your true sustainability performance. While dashboards show emissions targets and net-zero goals, a surprising amount of CO2 data remains hidden. Consider fuel receipts, EV charging apps, and forgotten spreadsheets. Corporate mobility is one of the most overlooked contributors to corporate emissions. And yet, it plays a direct role in your Scope 1 and 3 emissions.

At the same time, the regulatory landscape is evolving. The EU’s new Corporate Sustainability Reporting Directive (CSRD) sets higher standards for how companies report their emissions. That means you can no longer afford to treat fleet emissions as an afterthought.

In this article, we look at how to move from disconnected spreadsheets to actionable CO2 reporting. We will also explore how a digital mobility platform can help transform mobility data into strategic sustainability insights.

CO2 reporting in 2025: What you need to know #

Regulatory pressure is here, and the CSRD is already changing how companies report on environmental issues. Large organisations must report their greenhouse gas emissions clearly and do so in a structured, auditable way.

Some may think of it as just a bureaucratic exercise. Instead, it's a shift in how businesses demonstrate environmental accountability to stakeholders: investors, regulators, and the public.

At the centre of this transformation lies corporate mobility emissions.

• Scope 1 emissions include the direct fuel consumption from company-owned vehicles.
• Scope 3 emissions include the broader impact, such as business travel in personal cars, employee commutes, or even outsourced logistics.

These mobility-related emissions often comprise a large portion of a company's carbon footprint. However, they remain among the hardest to track.

Most businesses still rely on manual CO2 reporting, which includes collecting fuel receipts, downloading charging logs, and chasing spreadsheets across departments. This approach is extremely time-consuming, prone to error, and impossible to scale as reporting obligations grow.

Instead of chasing scattered data across tools and teams, companies need a more innovative way to connect the dots. This means turning everyday mobility data into a solid base for ESG compliance and strategy

Why fleet data is often missing from ESG reporting #

Corporate mobility emissions are often absent from ESG conversations despite their importance. Sure, companies do have concerns about fleet-related emissions, but many simply cannot access the full picture. The data exists, but it lives across platforms, is poorly linked, or is not tracked at all.

Here's where the problem begins:

• Fragmented data

Fuel card providers, EV charging platforms, mileage trackers, and employee expense reports help us understand emissions. Each tool provides different information, but together, they help us see the bigger picture. However, without integration, teams must manually combine fragmented mobility data.

• Manual entry is the norm

In many organisations, operations teams export fuel logs while HR shares lease vehicle data. Finally, sustainability leads compile it all, often using spreadsheets. This process is slow and frustrating and can lead to errors, omissions, and duplication.

• No link between data input

Even when data is available, it's rarely tied to specific vehicles, employees, or departments. A charging session may appear in a report; however, there is little accountability or insight without knowing who charged, when, and for which car.

As a result, valuable data that could support real sustainability progress is underused or even left out. Without integration, accuracy suffers, reporting becomes reactive, and teams struggle to meet deadlines with incomplete information.

Without a connected system, ESG reporting becomes a last-minute compliance task. Instead, it should be a strategic driver for emissions reduction and decision-making.

Unlock a sustainability fleet strategy with everyday fleet data #

When mobility data becomes centralised, connected, and easily accessible, it no longer poses just a reporting burden. Instead, it becomes a valuable asset. Companies can use the data to shape strategy, optimise operations, and prove measurable impact.

Centralised data shows more than just how much fuel or energy your fleet consumes. Central data uncovers patterns, exposes bottlenecks, and highlights opportunities. And when it's connected to real assets and employees, it gains accountability and actionability.

Imagine being able to:

• Monitor fuel and charging usage across your entire fleet in real-time across countries, business units, and vehicle types.
• Quickly break down emissions to pinpoint hotspots or benchmark departments.
• Flag anomalies, like high fuel use, incorrect charging behaviour, or CO2 outliers before they become costly
• Share progress with leadership through automated CO2 insights with visuals, clear metrics, and tailored reports.

This is the shift from passive, spreadsheet-based reporting to an active fleet sustainability strategy. It allows companies to set realistic but ambitious emissions targets and back those targets with accurate, real-world data.

With connected fleet data, you can respond confidently to ESG audits or investor questions. You can also more effectively engage internal stakeholders by sharing role-specific insights that drive accountability and action.

How Muto's Energy Management makes energy and mileage data work for you #

When fuel receipts, charging apps, and spreadsheets scatter, visibility and impact disappear. Muto’s Energy Management brings structure by centralising fuel and charging data. It links usage to the right vehicles and employees, and turns it into CO2-ready reports.

It connects to providers like Circle K to import large data sets. It flags issues, such as diesel stops on electric vehicles. It also makes compliance easier with custom CO2 filters by country, vehicle type, or date.

So, instead of spending days cleaning data, Muto helps you generate insights in minutes. This means shifting from manual reporting to measurable impact.

Conclusion: Make fleet data the heart of your ESG story #

Mobility emissions may be complex, but they don't have to be a blind spot. With the right tools, you can go beyond compliance and start using fleet data to tell a clear, measurable story of progress.

When you centralise your fuel, charging, and mileage data, you unlock new possibilities, such as smarter decisions, faster reporting, and greater accountability.

Fleet data isn't just a reporting obligation. Instead, it's a strategic resource supporting CSRD fleet reporting and company-wide sustainability goals.

Muto makes that possible. By connecting the dots between people, vehicles, energy stops, and emissions, we help you turn day-to-day operations into long-term impact.
