The Climate Change Authority of #Australia has issued a report that pinpoints #CarbonSequestration as critical to reduce emissions.

"Storing C away from the atm is integral, both to avert #GHGs from entering the atm & to #remove them from it."

The report notes that "while conventional #CarbonAccounting is simple and economically flexible, it does not consider crucial differences between different sources and sinks of #GHG #emissions."

"In order to assess carbon-biodiversity trade-off, the new paper examines the spatial relationships between biophysical & social values for #CarbonSequestration potential (measured as CO2 flux) & #biodiversity in Finland, using integrated valuation."

The approach used by authors "combines methods from #CarbonSequestration modelling, expert scoring approaches to biodiversity assessment and public participation geographic information systems (PPGIS)."

Results indicate "strong spatial associations between biophysical assessment of #CO2ย #flux and biodiversity priorities, and weaker associations between biophysical and social values."
