Many things that we do on this planet eventually generate the greenhouse gases that constitute the growing carbon footprint that can no longer be ignored. As governments are actively seeking ways to introduce effective measures against the threatening pace of climate change, the investors’ interest in the cleantech sector increases. The rise of green tech has inspired many entrepreneurs and scientists to step forward with innovative solutions that have the potential of reversing the damage that humanity has made to Planet Earth. As the goal of reaching “Net Zero” by 2050 still remains miraculous, technology seems to be our main hope for positive change. What Can Be Done to Reduce Carbon Footprint? ✅ Develop green air travel technologies Aviation accounts for up to 2-3% of carbon dioxide emissions. It’s much less than the amount coming from electricity or agriculture, yet these figures are much more significant than they may seem: thanks to the pandemic, the overall amount of emissions in 2020 dropped by a few hundred million tons. As since then we’ve got back to full-scale traveling, it’s pointless to hope for a reduction in air travel in the near future – so the only way to deal with it is to make it more sustainable. It’s highly unlikely that we will have access to zero-emissions air travel in the near future, but the foundation for developing such options has been set. In the future, we are likely to see more aviation companies switching to sustainable biofuel, an increasingly growing number of eclectic jets, and possibly hydrogen-powered planes.

What they do: ✅ Reduce animal product consumption Meat production is by far one of the most environmentally harmful industries. It’s one of the major causes of deforestation, loss of biodiversity, excessive water usage – and greenhouse gas emissions. Animals – particularly cows and sheep – create enormous amounts of methane as they digest food and produce manure. Overall, the meat and dairy industry is responsible for about 14,5% of global greenhouse emissions. While simply lowering the consumption of meat is already a significant step towards more sustainable agricultural practices, what would make a real difference at this point is a synergy of different technologies offering animal product alternatives. Startups to watch: Air Protein USA Country: 2019 Founding year: This startup strives to become a carbon-negative company by transforming captured CO2 into alternative meat. The technology is based on the findings made by NASA scientists, who discovered that a certain type of microbes can convert carbon dioxide combined with water and energy into highly nutritious protein.

What they do: ust as harmful to the environment as meat Jiminy’s USA Country: : 2016 Founding year A large percentage of our meat consumption comes from pet food manufacturing. This company has come up with a creative approach to the problem by replacing the meat protein in dog food with insect protein – or, specifically, crickets. Jiminy’s produces healthy and sustainable nutrition for pets that seems to be appreciated by both the owners and their pets. What they do: ✅ Capture CO2 from the atmosphere One of the ways to reverse greenhouse emissions is to capture carbon dioxide from the air. A huge problem with the current technologies for direct CO2 capturing is, however, that such machines use an unjustifiable amount of global energy supplies. That’s why this topic has been one of the hottest challenges for climate tech ventures – a sustainable and scalable way to collect CO2 is yet to be discovered. Consequently, the other focus for climate tech startups is the actual utilization of the captured gas. Turns out there are many ways to put CO2 into sustainable production, with more and more creative approaches coming up as the technology evolves. Startups to watch: Carbon Infinity United Kingdom Country: 2019 Founding year: This startup is determined to introduce a modular technology that would make capturing CO2 easier and more cost-effective, making carbon removal a largely scalable technology.
