Earth Tech 2050:
Announcing Our First Cohort of Top Climate Tech Startups

September 19, 2023

From ‘climate change’ to ‘climate crisis’ to ‘climate catastrophe’, we continue to update our language to reflect the increasingly devastating state of our burning planet. Recently, the U.N. chief António Guterres declared that “the era of global warming has ended; the era of global boiling has arrived.”

No matter the wording, the reality is clear: if we don’t take drastic action, we’re in serious trouble. 

We need to both rapidly deploy existing technologies, and support emerging climate tech that has the potential to massively reduce or remove emissions by 2050.

Enter our new nine-month program, Earth Tech: 2050, delivered in partnership with Social Innovation Canada. We’re helping to accelerate these critical technologies with the potential to each cut half a gigatonne of CO2e by 2050.  

Earth Tech: 2050 is an impact accelerator, offering each venture a custom program to achieve their missions.

We’re thrilled to introduce the first Earth Tech: 2050 cohort of 11 climate tech startups:

Carbon Lock Tech

Carbon Lock Tech is a carbon removal startup focused on converting organic matter into stable biocarbon and sequestering it long term in agricultural soils, sustainable construction materials, and green infrastructure projects. It is currently focused on scaling up its patented technology and advancing its research on biocarbon applications.

Cascadia Seaweed

Cascadia Seaweed is North America’s leading seaweed cultivation and processing company, supplying biostimulants for crops to increase growth and resilience, while reducing fertilizer use and feed additives to improve productivity and lower methane. Alongside its First Nation partners, Cascadia Seaweed is tackling climate change and food security with its nature-based solutions.

Circulus Agtech

Circulus Agtech upcycles organic waste to produce sustainable fertilizers. The Circulus System and its proprietary monitoring system allow users to manage organic waste and turn it into a valuable product for crop producers as an alternative to conventional fertilizers, to increase soil health and reduce greenhouse gas emissions.


CycleCarbone offers a proven CO2 capture technology to large emitters. The technology runs with thermal energy left unused by the host site, making it a simple, safe, and low-cost solution with no environmental harm.

Exterra Carbon

Exterra is a global leader in surface carbon storage technology, transforming mineral waste into large-scale carbon sinks. Providing turnkey solutions for industrial emitters and direct-capture companies, they ensure permanent, verifiable CO2 storage. Their process also extracts carbon-neutral critical minerals from waste, supporting worldwide decarbonization through the mineral value chain.


GreenLIB specializes in decentralized, modular lithium-ion battery recycling, championing sustainability, efficiency, and tailored solutions for the evolving e-mobility landscape.

Kinitics Automation

Kinitics Automation produces motion control products using shape memory alloys. Their new electric valve actuator replaces methane-venting equipment commonly used in the natural gas industry, thereby eliminating methane emissions at the source. 


NanoTerraTech is creating bio-graphite from forestry biomass waste for the EV battery market. The transition to electromobility is a generational opportunity, and their bio-graphite is a sustainable, scalable, drop-in solution that also permanently captures carbon. 

Rockburst Technologies

Rockburst is a mining startup developing a new comminution (the crushing and grinding of ore) technology called Transcritical CO2 Pulverization, which has the potential to slash 2% of the world’s electricity consumption and associated GHG emissions. 


SolarSteam delivers renewable heat through enclosed concentrated solar technology, and offers a game-changing solution for industrial clients by reducing their costs and emissions.


TerraFixing is a Canadian startup that has developed the only Direct Air Capture (DAC) process for capturing CO2 in cold climates. Their innovative IP-protected technology enables them to deliver affordable and scalable carbon removals at the gigaton scale <$100/tCO2.
