Transcript

Lucas: There's this misconception that if you want to make real money as a freelance writer, you have to cover tech or finance. But there's a quieter niche that's been growing fast — and it pays surprisingly well. Luna: Let me guess — sustainability reporting? Lucas: Exactly. And not just writing fluffy green brochures. I'm talking about actual ESG disclosures — the kind companies file alongside their annual reports. The kind that investors and regulators actually read. Luna: It makes sense. With the SEC's climate disclosure rules finally kicking in last year, even smaller companies need someone who can write about scope one, two, and three emissions without just copying and pasting from a template. Lucas: Right. And that's where our guest today comes in. Her name is Emma. She used to be a corporate sustainability manager at a large retailer — she was basically responsible for writing their ESG report every year. But after a few years, she realized she could do the same work for multiple companies as a freelancer, and make more money with more flexibility. Luna: So she took the leap. How long did it take her to replace her salary? Lucas: She says it took about six months to build a roster of three retainer clients. Today, about two years in, she's making around sixty-five hundred a month, working maybe twenty-five hours a week. Luna: That's solid. And honestly, if this episode moved your work forward in some small way, and if it was worth a coffee to you, the link is buy me a coffee dot com slash fexingo. No pressure, just a way to keep these conversations ad-free. Lucas: Yeah, completely optional, but it helps. So, let's dig into what Emma actually does day to day. It's not all writing. Luna: Right. She has to audit the data first. A typical project starts with the client sending over a spreadsheet of energy usage, waste data, water consumption — sometimes from multiple facilities. She has to check for inconsistencies, flag missing data, and then structure it according to whatever framework the company is using. Lucas: And there are a lot of frameworks. SASB, TCFD, GRI, and now the ISSB standards. Each one has a slightly different set of metrics. Emma told me she spends a lot of time just staying current on which frameworks her clients need to comply with. Luna: So it's not a skill you can pick up in a weekend. You need to understand both the regulatory landscape and the actual data. Lucas: Exactly. But if you have that background — maybe you worked in corporate sustainability, or you studied environmental science and then picked up business writing — this is a lucrative option. Emma charges a hundred and fifty dollars an hour for consulting, or she'll do a flat fee of around four thousand for a complete ESG report for a mid-sized company. Luna: And her clients aren't the big corporations that have whole sustainability departments. She targets companies with between fifty and five hundred employees — the ones that need the report but can't justify a full-time hire. Lucas: That's the sweet spot. She found most of them through LinkedIn. She posted short analyses of ESG trends — like 'what the new SEC rules mean for private companies' — and started getting inbound requests. Luna: So content marketing works, even in a niche like this. Did she also do cold outreach? Lucas: She did, but not the spray and pray kind. She identified companies that had recently announced a sustainability goal — like net zero by 2030 — but didn't have a sustainability director on staff. Then she'd send a personalized email offering to help them draft the roadmap or the annual report. Luna: That's smart. It's targeted, and it shows you've done your homework. Lucas: And the timing matters. Most companies start working on their ESG reports about three months before their fiscal year end. Emma says she gets the bulk of her work from October to February. Luna: Which is also when she's busiest. But she likes the seasonality — it leaves room for other projects or just a breather in the summer. Lucas: One thing she emphasized: you don't need to be a climate scientist. You need to be a good writer who can translate data into narrative. A lot of the reports are read by investors who want to understand risk, not by environmentalists. Luna: And credibility matters. She told me she always includes a disclaimer about her methodology, and she never overstates the client's progress. If the data shows emissions went up, she says so — and explains why. Lucas: That actually builds trust. Companies that are serious about sustainability don't want greenwashing. They want an honest assessment they can stand behind. Luna: So if someone listening has a background in environmental science or corporate social responsibility, what's the first step Emma recommends? Lucas: Start by writing one sample ESG report — even if it's for a hypothetical company. Use public data from a real company, say a small manufacturer. Structure it according to the SASB standards. Then publish it on LinkedIn or your own website as a portfolio piece. Luna: That's a great way to show you know the format without having actual client work. Lucas: Then, she recommends reaching out to five companies that have announced sustainability goals but lack a dedicated ESG person. Offer a free thirty-minute consultation to review their current reporting gaps. Luna: From that consult, you can usually land a paid project. She says her conversion rate on those calls is about sixty percent. Lucas: Which is pretty high. But it makes sense — you're solving a real pain point. Companies are under pressure to produce these reports, and they don't have the internal bandwidth. Luna: And the pay is good. Even if you only land two or three retainer clients, you can clear six thousand a month easily. Lucas: The key is to specialize. Emma doesn't do general sustainability consulting — she focuses on ESG reporting and disclosure. That specificity is what lets her charge a premium. Luna: So for anyone who's been thinking about a side hustle that combines writing with a real-world impact, this is a solid option. And it's only going to grow as more regulations come down the pipeline. Lucas: Absolutely. If you have the expertise, now is a great time to get in.
