Global Climate Solution Stocks

Bicicletas Monark is a Brazilian bike manufacturer. We exclude them because while more bikes is better for climate, they, as of 2025, still do not generate most of their revenue from electric bikes which more generally replace fossil fuels for commutes.

CEMIG is a Brazilian utility that generates its power from zero carbon sources like hydro, solar, and wind

CELG is a Brazilian electrical utility that generates all of its electricity from hydropower, thus passing our fossil fuel filter for utilities

CEB is a Brazilian electrical utility that, again in our 2025 review, does not disclose where it generates its electricity from, so we exclude it for lack of information

Estre Ambiental is a Brazilian waste collection company that both captures methane at its landfills and processes some of its trash in waste to energy plants, which avoid the need for new fossil fuels
