Climate change is a real threat to our planet and it’s our responsibility to fight it. There are nowadays many climate-tech startups that are taking a significant effort to fight climate change by inventing and developing products and services. The goal of these startups is to make the economy and society more sustainable, efficient, and clean. 

Difference between cleantech and climate-tech

According to Clean Energy Venture, the term cleantech is used to describe any new business model or technology that increases the performance, productivity, and/or efficiency of production while minimizing the negative impacts on the environment. The term climate-tech instead, is used to address climate change, and to describe any new business model and technology that mitigates the impacts and drivers of global greenhouse gas emissions. Both of the terms are covering many common areas, however, there is a key difference. The term climate-tech that is used to describe technologies that mitigate climate change is only covering a portion of humanity’s overall environmental effects, while cleantech is covering a much broader swath. Simply, climate-tech covers a broad set of sectors dealing with the challenge of decarbonizing the global economy, with the aim of reaching net-zero emissions before 2050, whereas cleantech refers to a wide variety of environmentally-friendly practices and technologies.


There are various clean and climate-tech trends to follow in 2021. Here are three of them explained:


Green hydrogen, a zero-emission fuel, is an alternative fuel generated with clean energy. Green hydrogen is experiencing a global resurgence and it has been identified as the clean energy source that could help bring the world to net-zero emissions in the future. Green hydrogen is made using electricity to split the hydrogen molecules from oxygen molecules in water. The byproduct is not carbon dioxide, but water. According to Gregory Nemet, professor of public affairs at the University of Wisconsin’s Energy Institute, Green hydrogen is forecast to fill 15% to 20% of the world’s energy needs that will not be easily met with battery, wind or solar power.  A recent survey of 1000 industry executives concluded that hydrogen fuel cell technology will ultimately outperform battery-powered EVs.

Electric vehicle infrastructure

The year 2020 may be seen as a defining year for electric vehicles. Even during the height of the lockdown, EV sales continued to grow as certain brands were ahead of the market in offering and fulfilling online sales and no-contact deliveries. In 2020, battery electric (BEV and plug-in hybrid vehicle (PHEV) sales saw a sharp upward trajectory, according to Automotive World. It has been predicted by Deloitte that a third of new car sales would be electric by 2030. The most important steps on this journey is a joined-up approach and continued investment in infrastructure. If 2020 was a defining year for EVS, it can be expected that 2021 needs to be a defining year for the charger.

Artificial intelligence

Artificial Intelligence, AI, is a technology that will be an important help in climate related problem-solving. According to Forbes, AI can accelerate the response to  climate change. Climate change is happening everywhere in the world, and AI can be a great help in terms of reducing greenhouse gas emissions. Artificial intelligence is predicted to assist organizations in industries from consumer products to retail to automotive and this way fulfill up to 45% of the Paris Agreement targets by 2030. It is estimated that AI is likely to reduce GHG emissions by 16%.
