The net-zero transition is expected to need about USD 9.2 trillion per year in physical-asset spending on average, roughly USD 3.5 trillion more per year than current spending.

Further, to keep 1.5 degrees Celsius within reach, the world needs 42% emissions cuts by 2030 and 57% by 2035. This is a trajectory that typically requires companies to move beyond disclosures into real abatement programs like efficiency retrofits, electrification, low-carbon procurement, and verified removals for residuals.

These startups illustrate how innovation is moving beyond strategy into scalable technologies and platforms that help organizations reduce emissions and manage climate risk.

They also enable companies to operationalize net-zero commitments through practical, deployable solutions.

Indonesian startup Regenesis Materials develops recycled eyewear materials made from ocean-bound plastic waste and captured CO2 to enable net-zero supply chains.

The startup collects plastic waste from rivers and mangroves and captures atmospheric CO2 through its ECOFUSION process using coconut shells. Next, it integrates bio-based inputs, recycled carbon fiber, graphene, aerogel, and glass microspheres using nanotechnology to create high-performance nanocomposites.

Further, the startup locks sequestered carbon into frames and processes materials using solar and wind energy. It also captures production emissions with the help of air filtration systems and structural operations to reduce and offset emissions.

Its materials remain compatible with existing manufacturing machinery and support closed-loop recyclability. The frames showcase mechanical properties comparable to conventional nylon and acetate alternatives while lowering reliance on virgin plastic.

4. Arrhenius – Algae Carbon Removal

  • Founding Year: 2023
  • Location: Horw, Switzerland

Swiss startup Arrhenius offers a biomass carbon removal and storage (BiCRS) technology that permanently removes CO2 from the atmosphere using microalgae.

The startup cultivates microalgae in modular outdoor photobioreactors where sunlight drives photosynthesis. This enables the algae to bind atmospheric CO2 while releasing oxygen.

After this, the startup harvests and dries the biomass to a carbon content exceeding 50% and stores it underground in stable geological sites like disused gravel pits or mines.

Thus, the startup combines energy-efficient cultivation, measurable carbon accounting, modular scalability, and localized operations to reduce transport emissions.

5. G-Plus Technology – Industrial Steam Heat Pumps

  • Founding Year: 2023
  • Location: San Giovanni Teatino, Italy

Italian startup G-Plus Technology provides a water-lubricated twin-screw steam compressor that generates industrial steam up to 200 degrees Celsius with zero direct carbon emissions.

GP-SC is the startup’s water-based solution for high-pressure applications into steam heat pumps, solar thermal fields, and mechanical vapor recompression (MVR) systems. It compresses low-pressure or waste steam, increases its temperature and pressure, and delivers high-value process heat for medium-temperature industrial applications.

The compressor uses water as a natural heat transfer and lubrication fluid with zero global warming potential and zero ozone depletion potential. With this, evaporative compression enhances sealing efficiency, stabilizes performance, and supports continuous industrial operation under high-pressure conditions.

Through applications like MVR, renewable steam generation, steam heat pumps, and thermal energy storage, the technology converts residual heat and solar-heated water into reusable steam. Also, it reduces reliance on gas-fired boilers in steam-dependent sectors.
