About Sustainability & Climate
Sustainability & Climate is the bench for builders who point their tools at the planet. Expect a solo founder's carbon calculator, a weekend hardware rig for monitoring a home's power use, a small marketplace for repaired goods, or a service that helps a team report its emissions. Some are polished businesses and some are early prototypes shipped in public. Each one is listed by the person who made it.
Every product here sits in one main category, and this page gathers everything from its four subcategories in one place. Use the filters to narrow the pile, and sort by community votes if you want to see what other builders and buyers rate. Votes cannot be bought, so the order reflects real interest. By default the newest launches come first, which makes this a good page to revisit if you like seeing what was made this week.

Sustainability & Climate: questions answered
- What kind of product belongs in Sustainability & Climate?
- Products and businesses whose main purpose is to reduce environmental harm, measure it or help people live with it. That covers software, hardware and services. If environmental benefit is a side effect rather than the point, a different main category will probably fit better.
- How do I choose between the four subcategories?
- Pick the one that describes what your product does day to day. Climate tech suits broad tools, green energy suits power generation and use, circular economy suits reuse and waste, and carbon tracking suits measurement and reporting. Your main category is chosen at submission and included free.
- Can my product appear in more than one subcategory?
- Yes. Every listing has one main category, included free. A paid upgrade adds up to 3 more categories for $5. This helps if your tool genuinely spans, say, energy and carbon measurement.
- How do I get my project listed here?
- Go to /submit and paste your website address. An AI drafts the profile from your site, then you check and edit every field before anything goes live. A paid launch costs $5, while a free listing joins a queue of about 6-8 weeks.
- What should I check when comparing tools in this field?
- Look for a clear description of what the product measures or changes, and how you can verify it. Check who built it, whether the maker explains their method, and what the tool needs from you to work. Vague green claims without detail deserve a second look.
