@xprize announced the winners of its $100M CDR competition. The grand prize of $50M went to @mati_carbon for ERW. Other awards included $15M to @NetZero, $8M to @VaultedDeep, $5M to @undocarbon & $1M each to Planetary & Project Harar.
Microsoft has signed a large-scale carbon removal deal, purchasing 1.4 million tonnes of credits from @living_carbonโs reforestation projects on degraded U.S. mine lands.
๐จA recent field study conducted over the Great Barrier Reef has provided key insights regarding sea spray aerosols (SSA).
For the first time, it shows that SSA can reach the cloud base height, advancing Marine Cloud Brightening (#MCB) research.

2/ MCB is a proposed climate intervention that aims to reflect more sunlight by enhancing marine clouds.
The concept relies on artificially generated sea spray aerosols (SSA) at the ocean surface and their transport in sufficient quantities to low-level maritime clouds.
3/ A portion of the SSA that reaches cloud height can act as additional cloud condensation nuclei and modify cloud microphysical properties, potentially reducing the amount of solar radiation reaching the sea surface.
๐จA new 3-year study found that by combining crushed rock + compost + biochar could remove 51.7 million tons of COโe/yearโjust by treating 8% of Californiaโs rangelands.

2/ Researchers spread finely crushed metabasaltic rocks across test plots in Browns Valley, California, in each of 3yrs.
Along with the crushed rock, some of the applications included compost or a combination of compost & biochar (burned pine & fir left over from local logging).
3/ Other plots were treated with only compost, and a group of control plots received no treatment.
Throughout the year, the team monitored each plot for levels of soil organic and inorganic carbon, pore water dissolved carbon, aboveground biomass, and greenhouse gas emissions.

Microsoft has entered into the worldโs largest carbon removal agreement, securing a 15-year contract to purchase 6.75 million metric tons of permanent CDR from AtmosClear, a subsidiary of Fidelis, utilizing BECCS technology.
Occidental Petroleum has acquired carbon removal startup @holoceneclimate, marking its second direct air capture acquisition in two years. The deal was made through its low-carbon arm, Oxy Low Carbon Ventures, for an undisclosed amount.
๐จ๐We launched the first-of-its-kind Solar Geoengineering Events Calender last year, to create the go-to public resource for anyone tracking key events in #SRM. From conferences to job deadlines, we update it regularly.
