Our take
Conflicts in the 2020s and climate change are challenging energy companies, leading to an unprecedented demand for more commitment to renewable raw materials from all stakeholders. For companies, this means it is now no longer a luxury to save CO2 emissions where possible.
Cozero is a software company that creates products to fit that need. The startup was founded to enable companies to effectively decarbonise and it differentiates itself from competitors by framing these CO2 savings in the language of business - each measure details CO2 saved per Euro invested.
With over 70 enterprise customers, the company's next steps will involve accelerating its international expansion and advance its Climate ERP solution. Having already helped cut Vodafone's media carbon footprint by a third, the company is well set for even greater success as it continues to grow.
