Launching South Africa's ESG dataset with the JSE


Hi Reader,

I’m proud to let you know of a first for us at Unifi, and as far as we can tell, a first for South Africa: we have partnered with the Johannesburg Stock Exchange on South Africa’s locally built and relevant ESG dataset, which is now live on the JSE Market Data MarketPlace.

The JSE Unifi ESG product suite is a full coverage dataset across the JSE universe (240+ listed companies) with three years of history, which includes nearly 25,000 disclosures spanning about 60 metrics in the set (initially), and a benchmark layer built on at least five denominators that are actually African-centric, not borrowed.

There are many reasons that we did this, but one that is central to who we are as Unifi: it’s rooted in the fact that ESG isn't African-centric enough.

As a regular reader of my newsletter, you’ve heard me reflect on how challenging it is for our clients to respond to investors, customers and regulators. Their data and reporting requests, frameworks and standards are often grounded in topics that aren’t aligned to how a business has to operate sustainably in Africa.

It’s not a complaint, but it is the reason Unifi exists. For our local clients, we aim to make solid businesses more visible. We know there is important data not being seen, because these businesses are being looked at through a keyhole.

Run a JSE-listed company through a standard global ESG framework and you'll get a score. What you won't get however is a signal of relevance and impact, because the frameworks look for what they look for, and not much else outside of it. Social and economic factors are under-weighted and under-valued. The nett result is that everyone clusters in the same unhelpful middle, and the metrics that actually predict risk and reputation here sit outside the framework entirely.

We didn't build this because ESG data is a nice adjacent product line. We built it because solid, well-run businesses in this market deserve to be visible to capital on their own terms, not on terms written somewhere else.

We’ve heard often that data availability is a challenge of asset owners and managers in fulfilling ESG and impact investment mandates – we expect that to change.

As South Africa transitions soon from a voluntary disclosure regime to one that adopts IFRS S1/S2 as the mantle for regulated disclosure, we also hope that this baseline dataset provides the springboard from which listed companies and their investors (and other stakeholders) can engage meaningfully on how to make data more consistent too.

You can find the product suite here on the JSE MarketPlace.

The JSE and Unifi will be hosting a webinar on this product suite on Tuesday 29th September 2026, 3pm SA, so let me know if you'd like an invite to that, or feel free to share the info with your network.

Also happy to demo the dataset if you'd like to know more.

Special shout-out to our awesome partners, Tracenable, who have supported us in this endeavour.

Hi Reader, I was looking at some of the data we've compiled in the JSE ESG dataset, which reveals an interesting dynamic of how the same data point can tell two different stories. But first, in case you missed it, a couple of weeks ago we launched an African-centric full-coverage ESG dataset with close to 25,000 disclosures, three years of history and a benchmark layer with the JSE, available now on the JSE Market Data MarketPlace. And we have a webinar coming up next week to showcase the...

Hi Reader, I'm a little embarrassed. For many of you this is the first time a newsletter has arrived from me in close to a year. I've broken all the rules of what the content gurus say about consistency, and I'll unashamedly put the blame at the door of busy-ness. It's been a wild 2026 so far and we've been building some really interesting stuff with some even-more-interesting clients and partners. So I'll be sharing some fortnightly reflections on those builds, with some information about...

Hi Reader, A CSO at a major private-equity fund said something that won’t leave me: “My pet complaint is the ‘ESG score’ investors sometimes ask for. There is no single organisation that calculates a Fund’s ESG score, but several, using different methodologies. And to my knowledge no recognised international body that vets these things. Very irritating, I just leave the question blank on surveys.” It’s blunt, but fair and it mirrors what we see across Southern Africa every week. Just...
