"A comprehensive #bioenergy accounting model with a multi-dimensional analysis was
developed in a new study based in #China by combining spatial, life-cycle, and multi-path analyses."
Summary in a 🧵 below ⬇️ 1/6
Accordingly, "the #bioenergy production potential and #GHG emission reduction for each distinct type of #biomass feedstock through different conversion pathways were estimated in the study." 2/6
"The sum of all available organic waste (21.55EJ/yr) & energy plants on marginal land (11.77EJ/yr) in China produced 23.30EJ of #bioenergy & reduced 2535.32Mt CO2-eq emissions, accounting for 19.48% & 25.61% of China’s T energy production & C emissions in 2020, respectively." 3/6
Furthermore, in this study, "life-cycle emission reductions were maximized by a mix of #bioenergy end uses based on #biomass properties, with an optimal 78.56% bioenergy allocation from biodiesel, densified solid biofuel, biohydrogen, and #biochar." 4/6

The Frontier Buyers has teamed up with carbon removal developer Phlair, committing to invest $30.6 million in electrochemical direct air capture to remove 47,000 tons of CO2 from 2027 to 2030.
B.C. Centre for Innovation and Clean Energy launched Canada’s first CDR fund, offering $3M to support early-stage, hard-tech carbon removal solutions for decarbonizing B.C. and Canada.
"Geoengineering isn't just a climate issue—it's a geopolitical chess game. Only US & China have power to unilaterally deploy #SAI at scale."
Will they race to control skies or seek climate diplomacy? New study explores 4 futures🧵1/9
2/ SAI could cool the planet—but who controls it controls global climate security.
Key risks of unilateral deployment:
🔴 Termination shock
🔴 Environmental disruptions
🔴 SAI as a potential weapon
🔴 Geopolitical leverage—both a threat & opportunity
3/ This creates a security gap:
The US & China are locked in great power competition, yet neither has a clear strategy on SAI.
Who moves first? Who controls the stratosphere? The dilemma: Deploy & gain influence—or deter & risk falling behind?

@Arcaclimate has secured $12.2 million from Australian venture capital firms Side Stage Ventures and Saniel Ventures to help scale its carbon removal technology at Western Australian mine sites.
Qualterra, a company that converts organic waste into biochar for soil health and carbon sequestration, secured $4.5M to expand biochar production, launch carbon credits, and scale plant propagation.
🚨What if we could remove methane from the atmosphere—fast?🚨
A new study proposes two ways to use 𝐚𝐭𝐨𝐦𝐢𝐜 𝐜𝐡𝐥𝐨𝐫𝐢𝐧𝐞 to destroy this powerful GHG: one with reactors, the other by releasing chlorine into the air. But one of these ideas comes with serious risks:🧵1/10
2/ Methane is a powerful but short-lived greenhouse gas, responsible for ~0.5°C of global warming. "It’s 80x more potent than CO₂ over 20 years," and its atmospheric levels continue to rise—despite global pledges to cut emissions.
3/ In nature, hydroxyl (OH) radicals break down methane, but the process is slow.
Chlorine (Cl) radicals can do the same job 16x faster, though they are far less abundant in atm—destroying only ~1-4% of methane today.
