Harnessing new technologies is easier than ever, and some can help environmental journalists hold power to account, according to a panel of experts at the 2025 Society of Environmental Journalists (SEJ) Conference in Tempe, Arizona.

Many of the resources shared by the experts are free or low-cost, making them ideal for freelancers or under resourced newsrooms.

Journalists can find information on company ownership, financiers and funders through company registries, stock markets, international databases and more.

Often, this information can be found on free-to-access online databases, Meers said. SEC.gov, OCCRP Aleph and OpenCorporates are good places to start.

Journalists affiliated with well-resourced newsrooms and universities can take advantage of paid databases like LexisNexis and Sayari.

Finally, journalists can get creative with satellite and geospatial data, layering datasets on top of one another to “create a dialogue between them,” Meers said.

By combining satellite imagery from sources like NASA Worldview with geospatial data from websites like Protected Planet, journalists can get a dynamic bird’s-eye view of environmental impacts and create compelling visuals for their audience. Continue reading →
