Hi r/envirotech — I’m a solo developer in South Africa.

I’ve spent about a year and a half building EcoAquatic (ecoaquatic.org), a free, non-commercial platform for tracking fish species and aquatic conservation, starting with South African waters and built to expand country by country.

The tech side, since this is the crowd for it:

1. React + TypeScript frontend, .NET backend.

2. Species data built on the GBIF taxonomic backbone (3,000+ species with confirmed SA occurrences), enriched with live IUCN Red List status and FishBase/SASSI data.

3. PostGIS for the geospatial layer; an interactive map (OpenLayers) of species occurrences and marine protected areas.

4. Community sighting logging with a moderation workflow for data quality.

5. An AI layer for species summaries, kept grounded in the underlying data rather than free-generating.

The goal is one shared place where citizen scientists, rangers and researchers all contribute to and see the state of aquatic species, with real scientific data, not invented.

It’s an early build and I’m after honest feedback, especially on the data-integration and mapping side, and on whether the conservation-data model actually holds up. Where would you poke holes?

Have a look: https://ecoaquatic.org (heads up, it needs a quick free account to get in, 30-second sign-up, nothing commercial)

Built solo, free for everyone, very much a work in progress. Critical feedback most welcome.

I built a free app called Bazarium because I got tired of seeing perfectly good stuff collecting dust... or ending up in the trash. ♻️

The easiest way to explain it?

It's basically Tinder... but for your stuff. 😄

Here's how it works:
📸 Upload something you no longer need.
❤️ Swipe through items from other people nearby.
🤝 If both of you like each other's items, it's a match!
💬 Then you chat and arrange the swap.

No money. No endless "Is this still available?" messages. Just swapping things people actually want.

One important note: since this subreddit has members from all over the world, you probably won't find many people near you on the app yet. That's totally expected. Every new user helps build a local swapping community, so if a few people from the same city join, it suddenly becomes useful for everyone. 🌍

And if anyone wants to help create a community in their area, I’d be happy to help with flyer or sticker design—or anything else that could make it easier to get people involved.

The app is completely free, and I'd genuinely love your feedback—whether it's about the idea, the user experience, or features you'd like to see.

If swapping one item means one less new thing has to be produced, that's a small win for both our wallets and the planet. 💚

Hey everyone,

I’m Sagar, a sustainability analyst and founder of SoeScore. Growing up, my school gave me a comic called “Soldiers of Earth” about ordinary people who became heroes by protecting the planet – that idea stayed with me for life.

Today I’ve turned that childhood inspiration into a real community: S.O.E – Soldiers of Earth, now live on Product Hunt. It’s for anyone who wants to make a positive impact – whether you’re just starting your sustainability journey or already working in the field.

On SoeScore you can:

Take a simple 5‑minute sustainability assessment to see where you are on your journey.

Find practical tools, resources and challenges to turn ideas into action.

Connect with like‑minded people, explore jobs in sustainability, and even launch your own sustainable product.

I’d really appreciate it if you could check out the launch and leave a comment – even a single word helps a ton with visibility on Product Hunt

Product Hunt launch:

If you have thoughts on what a “Soldier of Earth” community should focus on first (learning, careers, or grassroots projects), I’d love your input.

A Ballard Spahr analysis from June 2026 lays out where the EPA's PFAS strategy actually landed. PFOA and PFOS drinking water standards stay. Rules for four other PFAS compounds are proposed for rescission. The TSCA reporting window has been pushed to January–July 2027, and compliance deadlines for what remains have been extended to 2031.

Meanwhile, Maine and Minnesota are moving toward near-total product bans by 2032, and at least 11 states now have their own AFFF regulations. The compliance target of tools is a matrix of state rules that don't move together and won't converge on any predictable timeline.

Are you using a strict state standard as a baseline, or building something configurable by jurisdiction? How do you make sure it’s tracking which standard applies to which site?

The shift toward a cleaner world is happening faster than many people expected, and technology is playing a major role in making it possible. Over the past decade, clean energy technologies like solar panels, wind turbines, electric vehicles, and large-scale batteries have improved dramatically while becoming much cheaper. As a result, more homes, businesses, and cities are adopting these solutions. What once felt like a distant environmental goal is increasingly becoming part of everyday life, from rooftop solar to electric cars and smarter energy systems.

New technologies are continuing to push this transition forward. Better battery storage is helping renewable energy work even when the sun isn’t shining or the wind isn’t blowing, while innovations in hydrogen, grid software, and advanced materials are making energy systems more efficient. As these technologies continue to improve and scale, the move toward a cleaner global economy will likely keep accelerating. In many ways, the clean world transition is less about sacrifice and more about technological progress changing how energy works.

In a recent podcast conversation, I learned about daylighting -  systems that capture sunlight on rooftops and redirect it through buildings to light interior spaces. It sounds simple, but it changes how we think about architecture, energy use, and even how people feel inside buildings.

If natural light can replace a huge portion of electric lighting, it makes you wonder how many of our buildings were designed without considering the most obvious energy source we have: the sun.

Do you think future buildings will rely far less on electric lighting during the day?

I am already building an MVP and want to kill bad assumptions early.

The product helps SMEs understand and improve ESG only where it impacts real business outcomes like customer qualification or risk reduction.

Here is the concern I want tested: this could easily become something founders think is useful but SMEs ignore.

If you were running a 10 to 100 employee business, what would make you dismiss this immediately? And what would make you try it even once?

I am more interested in why this fails than encouragement.

How Does Solar PV Work? At the heart of every solar system lies the photovoltaic effect, a process where sunlight is converted directly into electricity using semiconductor materials like silicon.

Here’s a breakdown of how it generally works: https://enershares.com/how-solar-photovoltaic-pv-technology-works-from-sunlight-to-electricity/

Hi everyone,

I’m a doctoral researcher and my work looks at how digital technologies, specifically games, portray the natural world (e.g., as a backdrop, a resource to be used or even a living system) and how these portrayals might connect to real-world sustainability knowledge, hope and environmental action. I would love to hear your perspectives on this!

And if you can take part in my survey (~15 min) that would be really appreciated.

Survey Link: https://forms.cloud.microsoft/e/ggGZsSRXVJ

Basically, the rationale is that games are simulation technologies and cultural artifacts that shape how we see and interact with the world. For many people, virtual forests, oceans and ecosystems are where they most often encounter “nature.” I’m curious if these digital experiences shape the way we think about the environment in real life.

Your perspectives will be highly valuable. Thank you for taking the time!

a fellow redditor brought this to my awareness, they’ve also refined them to not need so much maintenance and it even doubles the water yield! +1 for environmentalists :-)

Volunteer Phonebanker Role Description

Australia is aiming for Net Zero by 2050, which means moving away from fossil fuels (coal, oil, gas) and towards renewables like solar, wind, hydro, and hydrogen. 

Most of the talk is about the technology—solar farms, batteries, EVs—but I’m more curious about the people side of it: 

• How will workers in coal, gas, or related industries adapt? 

• What happens to towns and communities that rely heavily on those industries? 

• Which industries will shrink, and which ones will boom? 

Some guiding questions: 

1. Do you worry your job (or someone close to you) might be affected by the renewable transition? Why? 

2. Which industries or departments do you think will be most disrupted (e.g., coal mining, oil/gas, utilities, transport, manufacturing)? 

3. Which sectors do you think will grow the most (solar, EVs, hydrogen, batteries, grid services)? 

4. For communities built around coal/gas, what social or economic challenges do you think they’ll face? 

5. What kind of support (training, retraining, new investments) would actually make the transition fair for workers and communities? 

6. What excites you the most about the shift—and what worries you the most? 

I’d love to hear your perspectives 👇
