Study finds global emissions of several banned ozone-destroying CFCs are increasing

Green Car Congress

But because they’re potent greenhouse gases, they still affect the climate. Combined, their emissions are equal to the CO 2 emissions in 2020 for a smaller developed country like Switzerland. That’s equivalent to about one percent of the total greenhouse gas emissions in the United States.

Researchers contend that large-scale forest bioenergy is neither sustainable nor greenhouse-gas neutral

Green Car Congress

Large-scale bioenergy production from forest biomass is unsustainable and will increase greenhouse gas emissions, according to a group of international researchers in an invited analysis in the journal Global Change Biology/Bioenergy. Fertilizer use, another important source of greenhouse gas emissions, could increase.
