ESG reporting for architects: how to create a professional ESG report

Introduction: ESG reporting in the architecture industry

The architecture industry has always shaped the world around us. Buildings, urban spaces and infrastructure are not just functional solutions, but the framework for how people live and work.

But expectations have changed significantly.

It is no longer enough to deliver aesthetics and functionality. Clients, investors and partners now expect architectural firms to document how their work contributes to the green transition.

This is where ESG reporting becomes central.

For architects, ESG is not only about internal operations. It is largely about the impact your advisory work has on the projects you are involved in. Your decisions influence material choices, energy consumption and CO2 emissions – often to a much greater extent than your company’s own direct footprint.

ESG is therefore not an add-on. It is a way to make your real role visible in an industry responsible for a significant share of global resource use and emissions.

‍

What does ESG reporting for architects cover?

ESG reporting for architectural firms is a structured way to document both your internal operations and your external impact through projects. This dual perspective is what makes the architecture industry unique.

On one hand, you have your own organization:

• Employees, wellbeing and working environment
• Governance, compliance and business ethics
• Internal energy consumption and operations

On the other hand, you have your advisory work:

• Design decisions affecting building lifecycle
• Material choices and resource use
• Energy optimization and CO2 reduction in projects
• Collaboration with developers and contractors

For architects, it is not enough to report only on internal factors. Your external impact is what is most often evaluated.

This means your ESG reporting should clearly address two areas:

1. How you run your own business
2. How your work impacts the world around you

‍

Why is ESG reporting critical for architectural firms?

ESG is not slowly entering the architecture industry. It is already embedded in the market.

The pressure mainly comes from three sources:

1. Clients and developers
The construction industry is under intense pressure to reduce CO2 emissions. Developers are therefore placing requirements across the entire value chain, including architects. You are expected not only to deliver design, but also documentation. To stay competitive, you must understand the environment your clients operate in, where ESG documentation and climate impact are central.

2. Regulation and standards
EU regulations such as CSRD and the growing focus on lifecycle assessments (LCA) mean that sustainability data is becoming an integrated part of construction projects. Architects are indirectly affected through their role in these projects. Additionally, new national regulations continuously impact the industry.

3. Competition
If two architectural firms are equally strong professionally, the one that can document sustainable solutions and measurable impact will have the advantage.

The conclusion is clear:

If you cannot document your ESG efforts – both internally and externally – there is a real risk of being deselected.

‍

What should an ESG report for an architectural firm include?

An ESG report for architects should be based on relevance.

This means it must reflect both your internal operations and your project impact.

Governance: structure and accountability

Governance remains important, but for architects it is primarily about documenting how you run a professional and responsible business. There must be clarity, structure and clear decisions around key business practices.

Typically, this includes:

• Compliance and business ethics
• Contract management and project responsibilities
• Risk management in advisory services
• Data protection and GDPR

Social: people at the core

As in other advisory industries, your employees are the core of your business. They create value and ensure operations run effectively.

You are expected to document:

• Employee wellbeing and working conditions
• Diversity and inclusion
• Recruitment and retention
• Skills development, especially within sustainability

Environment: where architects stand out

This is where architectural firms differ significantly.

Your internal operations have relatively low impact compared to your projects, and this distinction should be clearly reflected in your reporting.

ESG reporting should therefore be split into two levels:

1. Internal environmental impact

• Office energy consumption
• Travel and transportation
• Basic CO2 calculations

2. Project impact (the most important)

• CO2 calculations on projects (LCA)
• Material choices and their climate impact
• Design decisions that reduce energy use
• Documentation of sustainable solutions
• Principles and initiatives related to CO2, biodiversity, water, etc.

This is the part clients care about most.

How to create an ESG report for architects

The process is similar to other industries, but with a stronger focus on projects.

1. Choose a framework

A framework provides structure. It can be compared to guardrails – as long as you work within a framework, you stay on track. VSME is particularly suitable for architectural firms because it prioritizes relevance over complexity.

2. Conduct a double materiality assessment

Within VSME, there are 10 standard sustainability topics. Review them and identify which are material for your business.

You should separate:

• Topics relevant to your internal operations
• Topics relevant to your advisory work

For architects, project impact will almost always be the most significant.

3. Define data points

Using VSME and your materiality assessment, define the data points you need to report on.

Examples include:

• CO2 per project
• Share of sustainable materials
• Employee data
• Governance structures

4. Collect data

Once you have defined what data you need, the next step is collection. This can be done in Excel, but it is often more efficient to use a platform designed for ESG reporting for architects, such as Wardn.

In most cases, the data already exists in other systems and simply needs to be consolidated.

5. Write the report

With the data in place, you can write your report. It will typically be a combination of data and narrative.

Many architectural firms also include project cases that demonstrate how sustainability and impact are integrated into real work. This is where theory becomes practice and where claims are supported by real examples.

‍

ESG software for architectural firms

Many architectural firms start their ESG work in Excel, which makes sense in the early stages. The challenge arises as the work grows. Data becomes scattered across files and teams, projects are handled inconsistently, and documentation becomes difficult to maintain. This is typically when ESG starts to feel unnecessarily complex.

ESG software solves this by bringing everything together in one place. Project data, ESG metrics and documentation are structured so you can work systematically with both internal operations and project impact. For architectural firms, the value is particularly clear: it provides a consolidated overview of how projects impact climate and resources, while ensuring consistent and repeatable reporting year after year.

It also enables scalability. Instead of starting from scratch with each project or report, you can build on existing data and processes.

Wardn is built for exactly this purpose. The platform allows you to collect ESG data directly from projects, structure your reporting and document your impact towards clients and partners.

The result is not just an ESG report, but an operational tool that makes sustainability work easier in practice while strengthening your position in winning new projects.

Frequently asked questions (FAQ)

1. Why is ESG reporting important for architects?

ESG reporting is important for architects because it documents how architectural design decisions impact CO2 emissions, sustainability performance and project outcomes. Clients expect clear ESG data on both internal operations and project impact, making it a key factor in winning projects.

2. Do architectural firms need to calculate CO2 on projects?

Yes. CO2 calculations (LCA) are increasingly expected in construction projects. Developers and investors require documentation of carbon impact, and architects play a central role in delivering or supporting these calculations.

3. Is ESG reporting mandatory for architects?

Not always directly, but often indirectly. Many clients require ESG data due to regulations like CSRD, making ESG reporting a practical requirement in tenders and ongoing projects.

4. What makes ESG reporting different for architects?

Architects have a much larger indirect impact through their projects compared to most advisory firms. Therefore, ESG reporting must focus heavily on external project impact, not just internal business operations.

5. How do you get started with ESG reporting as an architect?

Start by choosing a framework like VSME, conduct a materiality assessment focused on project impact, define relevant ESG data points, collect data and structure it into a clear ESG report.
