Top 12 startups helping to fight climate change

Pollution is one of the greatest environmental threats to public health globally alongside climate change. In fact, household air pollution, PM2.5, and ozone pollution account for the fourth-leading health risk factor worldwide, causing 11.2% of total deaths. 

This is only exacerbated by rising temperatures, which have been increasing by 2 degrees Fahrenheit since the Industrial Era. Increased heat means increased ground-level ozone smog, which is created when pollution from cars, factories, and other sources reacts to sunlight and heat. According to the Natural Resources Defense Council, the hotter things get, the more ozone smog we have. And with Europe just having its hottest summer in recorded history, people should be aware of this pressing matter. 

This past September 7th was the International Day of Clean Air for Blue Skies, a day designated by the UN to raise awareness about air pollution and the risks that come with it. The day is designed to stress the need for a cooperative effort in addressing the pressing burden of air pollution that is driving climate change and affecting people’s health across the globe.

European business regulators and policymakers now seek resilient and adaptable business models and action toward sustainability is now at the forefront of many companies’ discussions. Let’s take a look at some of the most environmentally friendly startups that are helping fight climate change through their initiatives and how these changes will impact consumers.

Combustion engines are a big cause of pollution, in fact, In one year, the average gas-powered car produces four tons of carbon dioxide (CO2). To solve this increasingly dire environmental problem and as an alternative option to the traditional motor system, zero-emission vehicles have been on the rise. 

Although this has led to less energy being wasted and no air pollutant emissions, one of the challenges of electric vehicles is the accessibility consumers can have to power stations. As stated in a brief by the European Environmental Agency, if by 2050 most cars were electric in the European Union, then electricity consumption would increase by 10%—meaning that the electricity grid infrastructure would have to evolve drastically in order to meet the demand. 

CyberSwitching, a power management company that manages charging points for companies looking for green solutions, is stepping up to the challenge. The company offers green energy solutions to help customers dramatically reduce their electrical costs, thereby making it more approachable for businesses to install EV charging stations.

They promote the development of EV charging solutions that increase sustainability and independence from fossil fuels. CyberSwitching, which owns more than 20+ patents, is the main supplier of well-known brands such as HP, Cisco, Foxconn, Intuitive, Adobe, Ford, and many more.

After a couple of years of taking cleaning standards to a whole new level, the cleaning products industry experienced an uptick in sales—a phenomenon that will most likely stay with us for a while. Alongside a surge in demand, the ingredients of cleaning products have also been opened up to conversation, with their impact on the environment and people’s well-being at top of mind. 

In the United States, companies that make household cleaning products aren’t required by law to print full list of ingredients on their packaging, allowing them to continue offering products with “forever chemicals” that don’t break down in the environment and contaminate it without notice. Viking Pure was created with the mission of providing safer, cheaper, and infinitely more powerful products than the harmful chemicals most commonly used today. 

The company generates non-toxic, on-demand cleaning and disinfecting solutions for facilities in healthcare, senior living, education, and more. The disposal of Viking Pure’s products is environmentally friendly with no further contamination—allowing consumers to get the best from a cleaning product without any negative consequences on the environment.
