This is a community-authored list of resources on how to find companies that apply ML to climate tech.
The list started out of sourcing speakers for PAW Climate (the first conference on industry applications of ML to climate tech) and it quickly became clear that it should be shared with the community.
There are a great many companies at the intersection of ML and climate tech. The list of "Known Companies" below is not comprehensive, and it is biased towards the networks of the authors of this page (e.g. primarily US- and UK-centric). How can you find more?
The climate tech world is booming, and if you check again using any of the methods below in a month or two, there's a good chance there'll already be a lot of new companies.
You can search LinkedIn jobs for "climate change" + your favorite ML search terms. This produces pretty decent results, though they are not comprehensive - many companies do not advertise themselves as specifically targeting climate change. Many earlier-stage ones also don't have job postings on LinkedIn.
http://climatebase.org/ is the current state of the art directory of companies whose work is in some way related to climate. A query for "AI" produces decent results as well, though browsing through them all can be challenging.
naturetech.io is the best resource for companies that focus on naturetech. Many of these are using AI for any number of ecology and biodiversity related tech such as to monitor deforestation using satellite mapping.
You can pick a sector and search for companies with that keyword on LinkedIn, Climatebase, or Google, e.g. "smart buildings ai companies".
