"The Cartographer of the Green Economy" - building the map so others can find their way in.
In 2008, before "climate tech" was a pitch deck category, Leonard Adler sat down and built a job board. Seventeen years later, that job board has become the internet's most active community connecting people to careers that actually help the planet.
Before he built a newsletter empire, before he ran the largest climate jobs community on LinkedIn, and before he launched an AI career coaching platform, Leonard Adler co-founded a law journal about poverty at Georgetown. That thread - connecting people who care about the world to the resources they need - has run unbroken through everything he's done since.
Adler didn't come from climate. He came from justice. A Political Science degree from Stanford. An MPP from Harvard's Kennedy School. A J.D. from Georgetown Law, where he was named a Public Interest Law Scholar and co-founded the Georgetown Journal on Fighting Poverty. His first real job out of law school was directing student organizing at Equal Justice Works, a nonprofit wiring legal services to communities that couldn't otherwise afford them.
He moved through the early internet's legal-information wave - FindLaw, Nolo, Justia - honing skills in digital community building, content strategy, and the architecture of how people find professional resources online. These weren't detours. They were rehearsals.
In 2008, he launched Green Jobs Network with a thesis so simple it sounds obvious now: people who want to work in environmental and social-responsibility fields deserve a dedicated place to find those jobs. That place didn't exist. So he built it.
What he built over the next seventeen years is less a job board than a career ecosystem. The flagship platform at greenjobs.net hosts thousands of listings. The LinkedIn group - the largest in the world dedicated exclusively to green and climate work - counts over 135,000 professionals. The newsletter, featuring 200+ curated opportunities per issue, has crossed 100,000 subscribers. The Green Jobs Pod brings the conversation to audio. And in 2024, ClimateJobs.AI added machine-learning to the mix, giving job seekers AI-powered career coaching and cover letter generation tailored to the climate sector.
Through all of it, Adler has stayed rooted in the classroom-and-community side of career development. He has presented "Finding Green Jobs" at Stanford's Earthsys 290 master's seminar, spoken at the Commonwealth Club's Climate One program, addressed the National Career Development Association's annual meeting, and led workshops for diverse climate talent cohorts including the Empowering Diverse Climate Talent (EDICT) internship program. He is, in the most literal sense, a teacher with a platform that reaches six figures.
He is also patient in a field that celebrates speed. The green jobs space didn't explode until the Inflation Reduction Act poured billions into clean energy infrastructure. Adler was already there, already sending newsletters, already running the LinkedIn group, already building the community. When the wave hit, he had the infrastructure. That's not luck. That's the compounding interest of consistent work.
His company sits at 1700 Van Ness Ave in San Francisco, operates under the subsidiary Greenjob Placement Solutions, and runs a parallel operation at Green VC - a site tracking funding and startups in the environmental and social-impact space that he started in 2007, a full year before Green Jobs Network. The man doesn't wait for permission to map territory that doesn't have maps yet.
Adler's platform is not simply a directory. It is, arguably, a social enterprise that has quietly shaped how an entire generation of sustainability professionals found their first climate role. The job listings, the newsletter, the LinkedIn conversations - they are infrastructure for a sector that is growing fast and, by his own mission statement, should be growing faster. Every week, 100,000 people open their inboxes and find a curated list of ways the world could use their skills.
Not bad for someone who started as a law student with a journal about poverty.
Connect people who are seeking jobs that focus on environmental or social responsibility with jobs, career resources, and community.

People who want to work in environmental and social-responsibility fields deserve a dedicated place to find those jobs. That place didn't exist. So he built it.
- The Green Jobs Network origin story, 2008
Adler's career began not in climate but in justice. As a Georgetown Law student, he co-founded a journal on fighting poverty. As an Echoing Green fellow, he built a nonprofit doing research and action on economic disadvantage. The throughline is consistent: find the people who are underserved, build the institution they need, and make the connection. Green Jobs Network is that same impulse applied to the green economy - with 17 years of compounding behind it.
The Inflation Reduction Act of 2022 injected hundreds of billions into clean energy. Climate tech went from niche to national priority. When that wave hit, Adler was already on shore - 14 years in, with a 100,000-person newsletter list and a 135,000-member LinkedIn group. He didn't pivot to climate jobs. He had been there since before it was cool, building the distribution infrastructure that everyone else would later need.
There's a specific kind of credibility that comes from going back to Stanford as a practitioner - not to fundraise or recruit, but to teach a seminar. Adler has spoken at Stanford's Earthsys 290 master's program, the Commonwealth Club's Climate One series, the National Career Development Association, and the Empowering Diverse Climate Talent program. He doesn't just run the platform. He explains how to use the map.
In 2024, Adler launched ClimateJobs.AI - adding AI-powered career coaching and cover letter generation to the Green Jobs Network stack. It's a logical extension: if you already have the audience (100K+ newsletter readers, 135K LinkedIn members) and the data (25,000+ job listings), adding AI-powered matching and coaching is the next leverage point. He didn't wait for someone else to do it first.
