One thing we’ve learned from over 10 years of writing impact reports in education, climate, and health is that people often underestimate their importance. They are now a primary tool for potential clients, investors, partners, donors and prospective team members to assess the credibility of an organization. 

Research backs this up. PwC’s Global Investor Survey showed that nearly two-thirds of investors say they gain significant confidence from sustainability reporting when disclosures are comparable year-on-year. For nonprofits, a survey of 2,800+ US donors by Software Advice found that 60 percent of donors want impact stories that show how their first donation made a difference. 

Impact reports also shape first impressions. We regularly see candidates and prospective clients refer to our impact report more than our website.

They also act as a powerful internal tool. When we started drafting GreenCare’s Environmental Accountability Reports, a key client goal was that the CEOs of each Regional Health Authority would read and potentially reference them. Now we’re on year 8 of creating the report, and for the last three years, the CEOs have actually written the introductory letter.

If you’re looking to strengthen your approach to impact report writing, here are six principles we always come back to.

1. Know your audience (and engage with them)

Before drafting, decide who you’re really writing for. Is this primarily for funders, government partners, community organizations, internal staff, or investors?

Don’t guess what will resonate with your chosen audience. Speak to people you want to read your report and ask:

• What would you like to understand better about our work?
• Which sections of last year’s report (if you have one) did you actually read?
• What would make this report genuinely useful to you?

We always start here for our clients; even three short stakeholder conversations can completely change how you shape your impact reporting.

2. Decide on your delivery format strategically

The format of an impact report should reflect where and how your audience encounters your organization. Some teams rely heavily on printed reports for events or donor mailings. Others know most of their stakeholders will skim a digital version on a phone.

One of our clients started with a lengthy PDF and a printed version. They later noticed people weren’t picking up the larger reports at events, so we developed a short “at-a-glance” version that flew off the table. The longer digital report was still there for people who wanted more detail.

Much of this decision can be based on where you are in your impact report process. A digital solution can be highly effective, particularly if it can be reused over multiple years by building it on a Content Management System (CMS) such as WordPress. However, this approach works best when you have a clear understanding of your report structure and are comfortable maintaining a consistent format over time.

Good impact reporting practices can save you a lot of time and cost over the long term.

3. Tell a focused story (less is more)

Keep it short, this is not a research report! It is meant to be a snapshot, high-level and something someone can skim and gather key points. It can be tempting to cram everything into your impact report, but studies have shown that this does more harm than good. A 2023 study found that more readable sustainability reports tend to provide more firm-specific information that investors actually use.

Think of your impact report as an in-depth infographic, rather than a comprehensive archive of the year. Remember, it’s always possible to link to longer content, your website, or other resources (stories, case studies, technical papers, dashboards) for people who want a deep dive. This has a bonus of driving more engagement on your website. 

Be strategic with how you use data. A few meaningful statistics, paired with a short story or a quote, often carry more weight.

4. Align your section structure with business goals

Different sections of your impact report may serve different audiences. In one report we created for the UK-based Skills and Education Group Impact Report, we deliberately shaped the opening sections for government, leadership, and the board, while dedicating later sections to more detailed program and subbrands content for clients, members, and partners.

Instead of mirroring your organizational chart or program list, start by identifying the three to five messages you want readers to remember. Then build your structure around the audiences that most need to hear each message.

5. Define what success looks like before you publish

Impact reports are a significant investment for the team creating them, and they should be treated with the same strategic approach as any other major initiative. This means starting by asking basic questions like who and how many people you want to read it, and what you want those readers to say, feel, think, and do when they read the report. 

Once you’ve answered these questions, decide how you will track it. Consider methods like digital analytics, verbal feedback, follow-up emails, link clicks, and email opens.

6. Plan to leverage your report all year

The worst thing you can do is publish your report, upload it to your website, and call it a day.

The value of an impact report increases when you use it as a content engine. Distill major findings into blogs, short videos, social posts, event speeches and partnership proposals. Draw on stories for fundraising campaigns or internal communications.

A strong impact report can be one of the most effective ways to show the real value of your work and deepen trust with the people who matter. When it is clear, focused and grounded in evidence, it becomes a tool that informs decisions, strengthens partnerships and supports long-term credibility.
