DevvStream Corp., a prominent carbon management firm, has entered into a carbon-management agreement with Energy Efficient Technologies $(EET)$, an engineering firm known for reducing electricity use in commercial buildings. This partnership enhances DevvStream's portfolio by adding building-efficiency assets. Under the agreement, DevvStream will generate revenue from EET's carbon credits and international renewable energy certificates (I-RECs), while also benefiting from shared utility-bill savings. The collaboration targets a large market, with EET's CryoGenX4™ technology projected to save $20 billion in power costs and significantly reduce CO₂ emissions annually. This move aligns with the growing demand for energy-efficiency credits as a cost-effective decarbonization strategy, and positions DevvStream to diversify its income and help businesses reduce costs and emissions.
