What are the best tools for Climate tech?

The best tools for climate tech depend on what you're trying to do: build a climate startup, measure emissions, model climate risk, develop clean energy, or finance decarbonization.

If you're looking for a practical climate-tech toolkit, I'd organize it into six categories: carbon accounting, climate data and modeling, geospatial analysis, energy optimization, lifecycle assessment, and climate-tech business development.
