Interior Secretary Ryan Zinke on Friday pushed California to adopt President Trump’s forestry management recommendations by noting new data illustrating the carbon dioxide pollution California emitted this year as a result of massive wildfires.

The data released Friday showed that the California fires produced the equivalent in carbon emissions to one year of power plant electricity production. The emissions were the equivalent to nearly 68 million tons of carbon dioxide, the Interior Department said. The data was compiled by the U.S. Geological Survey that Zinke oversees as secretary.
