Snow covered street in Saporro, Japan
Sapporo is the snowiest major city in the world, and clearing it is expensive. Hokkaido’s cities spend on the order of ¥100 billion a year on snow management, using diesel trucks and manual labor, and across 12 cities in the region those costs have risen 1.8 times in a decade. None of that appears in Japan’s national decarbonization strategy, yet it is the problem Sapporo City wants solved, and it is the opening our Japan team has used to bring climate tech into a prefecture now designated a GX financial zone.
That is how subnational work tends to start. The national target sets a direction, and the region supplies the problem worth solving, the site to test on and the budget already being spent. Our teams in Japan, South Korea, China and California all described a version of it in this webinar.
1. One national target becomes many local economic models
All 17 of Korea’s major regions now have carbon neutrality and green growth plans, under a national target of roughly 40% emissions reduction by 2030. The interesting part is what the regions do with that mandate. Gyeonggi is building around industrial solar, corporate PPAs and climate tech startups. Seoul focuses on retrofits, efficiency and electrification. Jeollanam-do works on offshore wind and ocean energy. As Minsoo Chung, our Korea Program Lead, put it:
“Korea’s provinces and cities are becoming more than administrators of climate policy. They are becoming market makers, customers, ecosystem builders and testing grounds for the next generation of climate technology.”
2. The zone is the instrument
China’s local governments have run most of their early clean energy policy through industrial parks and economic zones, testing subsidies and rules inside a small area before applying them more widely. Goldwind, now the country’s largest wind turbine maker, was founded in Urumqi in 1998 and built its early business from the city’s economic and technological development zone, where Shane says land, rent and tax terms were part of what let it scale. After listing in Shenzhen in 2007, it moved to a development zone in Beijing, and grew again from there. Two decades of Chinese manufacturing strength were assembled one zone at a time.
3. Start with a problem citizens already feel
Hokkaido has been designated a GX financial zone, and our Japan team, led by Huong Ly-Le, has been working with Sapporo City to find where global climate tech meets local demand. The answer was snow (yep, snow!). Sapporo gets up to five meters of it a year, and snow management costs the region on the order of ¥100 billion annually. Removal is diesel-and labor-intensive, and across 12 Hokkaido cities have risen 1.8 times in a decade. Treating snow as a resource for data center cooling and thermal storage turns a municipal expense into an innovation agenda.
4. Where public funding stops, philanthropy has to work harder
California’s clean tech pipeline was built on public funding. CalSEED has awarded grants of up to $700,000 to 158 startups, and CalTestBed vouchers have given 67 startups access to third-party testing across nine University of California campuses and Lawrence Berkeley National Laboratory. That pipeline produced companies like Gridware, founded by a former lineman with no route into the venture community, which now has more than 1,000 wildfire detection units deployed across PG&E territory since 2020. Joy Larson, our California Program Director, was blunt about what comes next:
“Government funding has just gone off a cliff. That’s an opportunity for non-governmental money to support subnational work towards energy transition.”
5. Reinventing the wheel, one region after another
Subnational regions solving these problems rarely talk to each other. Our China team hosted delegations from Pakistan and Thailand during Shanghai Climate Week and took an EU Commission group through a Shanghai development zone, and in each case the questions were about things China worked out years ago inside its industrial parks. Korean startups from Gyeonggi went the other way, to Boston Climate Week, looking for customers and capital.
What we take from this
The opportunity is to connect these places more deliberately, so that a technology Hokkaido needs to tackle its snow challenge, for example, can be found in Korea or the United States rather than developed from scratch. There is still surprisingly little cross-pollination between these clean energy innovation ecosystems, and working at the subnational level also creates a way to keep moving when national ambition stalls.
