3What this role really is

A sustainability assistant collects and checks the data that goes into sustainability reports. You gather information, keep records organised, and make sure figures are correct. The work gives you a close look at what sustainability means inside a large business.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Microsoft Excel (Power Query, XLOOKUP, PivotTables) Intermediate

Consolidating multiple spreadsheets, cleaning raw data, creating basic charts and tables for internal reports, using XLOOKUP to match data.

Microsoft PowerPoint Intermediate

Creating slides from existing templates, formatting presentations, inserting charts and data tables for internal updates.

Microsoft SharePoint Intermediate

Managing document versions, uploading and downloading files, navigating team sites to find historical data or templates.

MS Teams / Asana / Monday.com Intermediate

Tracking your personal deliverables, updating tasks, sharing files with the team, communicating about data requests and deadlines.

Workiva ESG / OneTrust ESG (or similar ESG platform) Intermediate

Data entry into pre-built templates, running standard reports, responding to data validation queries within the platform.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Data Source Selection Escalate to Sustainability Analyst. You won't choose new data sources. Propose new data sources for approval; consult with manager on feasibility. Decide on primary data sources for a specific reporting area; inform manager.
Data Validation Discrepancies Flag discrepancies to Sustainability Analyst immediately; do not proceed until advised. Investigate discrepancies and propose solutions; consult manager for approval if significant. Resolve routine discrepancies independently; inform manager of significant or recurring issues.
Process Improvement Suggestions Suggest minor improvements to your direct manager (e.g., a better way to organise a spreadsheet). Propose and pilot small process improvements within your area of ownership; seek manager approval. Design and implement significant process improvements for a workstream; consult with manager and affected teams.
External Communication No direct external communication. All external queries or requests are escalated to your manager. Respond to routine data queries from internal stakeholders; all external communication must be approved by manager. Lead discussions with internal stakeholders on data requirements; represent the team in cross-functional meetings.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Data Accuracy Rate
Percentage of data points collected and entered that are free from errors or discrepancies.
Target · >98% accuracy on all collected and entered data points.

If you collect 100 energy consumption figures, no more than two should have a typo or be from the wrong period when checked by the Analyst.

Data Collection Timeliness
Percentage of assigned data collection tasks completed by their internal deadlines.
Target · 100% of assigned data collection tasks completed by the internal deadline.

All factory utility bills for Q1 are uploaded and categorised by the 15th of April, as per the schedule.

Query Resolution Time
How quickly you acknowledge and resolve data validation queries from the Sustainability Analyst or other team members.
Target · Acknowledges queries within 24 hours, resolves within 48 hours (for routine issues).

An Analyst flags an unusual spike in waste data on Monday morning; you've investigated the source and provided an explanation by Wednesday morning.

Documentation Completeness
The percentage of data sources and collection methods that are properly documented according to our internal templates.
Target · 95% of all data sources have complete and up-to-date documentation.

Every piece of energy data you've pulled has a clear note on where it came from, who provided it, and when, stored in SharePoint.

Proactive Problem Spotting
Identifying potential issues with data or processes before they become bigger problems, rather than just reacting.
  • You'll flag an unusual data trend during collection, ask clarifying questions about a data source that seems off, or suggest a small improvement to a repetitive task. For instance, you might notice that a particular site always submits data late and suggest an earlier reminder.
Learning & Application
How quickly you pick up new concepts (like GHG scopes) and apply them correctly to your daily tasks.
  • You'll correctly categorise emissions data after a training session, ask intelligent follow-up questions about reporting frameworks, and show that you're applying feedback from previous tasks to new ones. Your Analyst won't need to explain the same thing three times.
Team Collaboration
Your willingness to help out team members and communicate clearly about your progress and any roadblocks.
  • You'll offer to help a colleague with a tight deadline, keep your manager updated on data collection progress without being prompted, and ask for help when you're genuinely stuck. You're not a silo
  • you're part of the team.
Adherence to Process
Following established procedures for data handling, documentation, and reporting cycles.
  • You'll consistently use the correct templates for data entry, save files in the right SharePoint folders, and stick to the agreed-upon steps for data validation. It's about being reliable and predictable in your work.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Making a Tangible Difference

You'll see your efforts directly contribute to reports that hold the company accountable for its environmental and social impact. Knowing that the data you collected is helping us set better targets or make better decisions will be a real boost.

Seeing a graph in the annual report with data you personally verified, knowing it's now public information.

Learning & Development

This role is a fantastic learning ground. You'll get exposure to all aspects of corporate sustainability, from carbon accounting to supply chain ethics, and learn the practical application of global frameworks. Every day is a school day, honestly.

Mastering a new data platform or finally understanding the nuances of a complex reporting standard like CSRD.

Order & Structure

If you enjoy bringing order to chaos, this role will appeal. You'll be taking messy, disparate data and making it clean, consistent, and organised. There's a real satisfaction in creating a clear audit trail and a well-structured database.

Successfully consolidating 50 different spreadsheets into one clean, usable dataset for the quarterly report.

What frustrates people
  • The 'data scavenger hunt': Spending 60% of your time just finding and cleaning data from a dozen different systems and spreadsheets, none of which were designed for sustainability reporting.
  • Being the 'process police': Constantly having to remind colleagues about deadlines or data formats, even senior ones, who often see your requests as less important than their own operational targets.
  • The 'so what?' question: You've done a brilliant job collecting detailed water usage data, only for someone from a non-water-intensive business unit to ask, 'So what? How does this help us sell more widgets?'
  • The 'alphabet soup' of regulations: Just when you've got your head around GRI, a new IFRS standard or CSRD update lands, and everything shifts.
What this role does not give you
  • High-level strategic decision-making in your first year – that comes later, once you've mastered the foundations.
  • A quiet, predictable routine – expect urgent data requests and shifting priorities, especially around reporting deadlines.
  • Direct engagement with external stakeholders like investors or regulators – that's for more senior roles, though your data will feed into those conversations.
  • A role where all the data is perfectly clean and easy to get – honestly, it's rarely like that.

8Who you work with

Your accuracy and timeliness directly affect the reliability of our public sustainability reports and our ability to meet regulatory requirements. Get it right, and we maintain trust. Get it wrong, and we could face scrutiny or even fines. It's foundational work that has a big ripple effect.

Inside the business
  • Operations Managers (for energy, waste, water data)
  • Procurement Team (for supply chain data)
  • HR Department (for employee-related ESG data)
  • Finance Team (for data validation)
  • Sustainability Analysts (your direct team)
Outside the business
  • None directly, but your data feeds into reports for investors and regulators

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • A solid grasp of Excel (you can do more than just sum a column).
  • Experience in a role that required meticulous data entry or information organisation.
  • The ability to communicate clearly and professionally, both in writing and verbally.
  • A genuine interest in sustainability and a desire to learn how it applies in a corporate setting.
  • A track record of being reliable and organised in previous roles or academic projects.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Excel for Data Modelling

While we use dedicated ESG platforms, Excel remains a crucial tool for ad-hoc analysis, data cleaning, and building smaller, custom models. Moving beyond basic functions to Power Query and more complex formulas will make you much more efficient.

Power Query for data transformation · Advanced lookup functions · Data validation rules

  • This quarter: Take an online course on Power Query fundamentals.
  • Next quarter: Identify one repetitive data cleaning task you do regularly and try to automate it using Power Query.
  • Month 6: Build a small, multi-sheet Excel model that pulls data from different sources and performs a basic calculation.
  • Ongoing: Ask your Analyst for more complex Excel tasks to challenge yourself.

Quick win: Start using XLOOKUP instead of VLOOKUP today. It's more flexible and easier to use.

ESG Platform Configuration & Reporting

You'll start by just entering data, but as you grow, you'll need to understand how our ESG platforms (like Workiva or OneTrust) are actually set up. This means understanding how data collection templates are configured and how custom reports are built.

Data collection template design · Custom dashboard creation · User access and permissions

  • This quarter: Ask your Analyst to walk you through the backend setup of one of our ESG platforms.
  • Next quarter: Try to build a simple custom report or dashboard in the platform, even if it's just for practice.
  • Month 6: Document a small section of our platform's configuration for future reference.
  • Ongoing: Attend webinars or training sessions offered by the ESG platform provider.

Quick win: Spend 30 minutes exploring the settings and configuration options in Workiva or OneTrust – just see what's there.

11Staying current once you are in

What people here do to keep up
  • Attend industry webinars on new ESG regulations or reporting trends (many are free!).
  • Join a local sustainability network or professional group to meet others in the field.
  • Read key sustainability reports from leading companies to see what 'good' looks like.
  • Take online courses on data analysis in Excel or an introduction to Power BI.
  • Volunteer for a sustainability-focused project outside of work to deepen your practical understanding.

12The rising capability

What's rising in its place

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

Prompt Engineering for Data Summarisation

AI language models are becoming incredibly powerful at summarising dense documents and extracting specific information. Being able to 'talk' to them effectively will be a massive time-saver for reviewing reports or identifying key regulatory changes.

  • Clear and concise prompting
  • Context windows
  • Output validation

Basic Data Visualisation Storytelling

It's not enough to just collect data; you need to be able to show what it means. As you progress, you'll be asked to turn raw numbers into understandable charts and graphs that tell a clear story, even if it's just for internal team updates.

  • Choosing the right chart type
  • Clarity and simplicity
  • Basic design principles

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, a lot of the work in sustainability reporting involves repetitive data gathering and summarising. Good news: AI can take a big chunk of that off your plate, freeing you up for more interesting, impactful work. We're not talking about robots taking over, but smart tools helping you get through the grunt work faster.

In this role, you'll be on the front lines of data collection and organisation. AI won't replace your critical thinking or your need for human interaction, but it will certainly make the mundane bits much quicker. Think of it as a very efficient assistant that never gets tired of sifting through documents or drafting summaries.

Automated Data Extraction

Use AI tools like Microsoft Power Automate AI Builder to automatically scan and pull key data (like kWh, therms, or gallons) from hundreds of utility bills or supplier reports. This means less manual data entry and more time for checking the numbers, not typing them.

Peer Analysis Accelerator

Imagine having an AI assistant 'read' the sustainability reports of our five biggest competitors and summarise their key targets or climate strategies into a neat table for you. You'll use tools like ChatGPT-4 or Claude to quickly get competitive insights without hours of manual reading.

Regulatory Summariser

When a new, dense regulation (like a 100-page ESRS update) drops, you can feed it into an AI tool. It'll give you a concise summary of the key changes and what they mean for our reporting, saving you hours of dense technical reading.

First-Draft Narrative Generator

Got a table of emissions data? You can give it to an AI model and ask it to write a first draft of the narrative for the report. It'll highlight trends and progress towards targets, giving you a solid starting point that you can then refine and make truly human.
