#CDR-01 AFFORESTATION/REFORESTATION
"Afforestation/reforestation (AR) can generate net negative CO2 emissions, as growing forests remove CO2 from the atmosphere via photosynthesis and store it in living biomass, dead organic matter, and soils."

#CDR-03 OCEAN FERTILIZATION
"Ocean fertilization is a type of technology for #mCDR based on the purposeful introduction of plant nutrients (iron) to the upper ocean to increase marine food production and to remove carbon dioxide from the atmosphere."

How Ocean fertilization works:
"Ocean nutrient fertilization, like Fe could stimulate photosynthesis in phytoplankton, which would convert the ocean's dissolved CO2 into carbohydrate and O2 gas, some of which would sink into the deeper ocean before oxidizing."

#CDR-04 ENHANCED ROCK WEATHERING
"ERW accelerates the natural process of mineral carbonation. However, the carbonation process that sequestrates CO2 into the rocks is not immediate, with carbonation rates ranging from a few months to a few decades."
