CLIMATE TECH

A broad term for any innovative technology that has the potential to address climate change.

The term “climate tech” intentionally casts a wide net. It includes both physical and digital technologies. It includes technologies that reduce greenhouse gas emissions, technologies that remove emissions from the atmosphere, and technologies that enable adaptation to an altered climate. If a technology has something to do with solving any aspect of the complex and multi-faceted problem of climate change, then it can conceivably be considered climate tech. This all-inclusive focus acknowledges the breadth of the climate challenge and the diversity of solutions needed, but it also allows for a certain looseness when startups, investors, and others seek to define their impact.

Climate solutions need to come from across society, not just tech billionaires. However, as far as tech billionaires go, Bill Gates has a fairly grounded and strategic approach. In this video from Breakthrough Energy, the Microsoft co-founder explains the need for innovation to address climate change.

Why not stick with existing solutions, rather than rely on new technology?

The short answer is to do both. In 2018, the world’s leading climate authority, the Intergovernmental Panel on Climate Change (IPCC), published a landmark report highlighting the urgency of limiting warming to 1.5 degrees Celsius. The report outlines four potential pathways for reaching that goal. The pathways are vastly different, but one thing they have in common is a central role for new technologies. Relying on emissions-reducing technology isn’t the same as blind techno-optimism. New technology needs to go hand in hand existing solutions, deployed immediately. But the IPCC pathways make clear that the route to mitigation goes through innovation.

Where did the term climate tech come from? 

 

The term itself is pretty new. It only sprung into wide usage around 2020. However, some of the startups and investors in the space have been around much longer, as have some of the technologies themselves. Many climate tech players have been around at least since the boom in interest in “cleantech” from 2008 to 2011.

 

What’s the difference between cleantech and climate tech? In theory, cleantech is technology that minimizes negative impact on the environment with a heavy focus on the energy industry, while climate tech has a focus on addressing climate impacts. In practice, there’s a whole lot of overlap between the two terms. Clean Energy Ventures has a good explainer on this, but the key thing to note is that these industry descriptions aren’t scientific classifications. Some technologies fit well under a given umbrella, and others don’t. A lot of cleantech investments didn’t pan out for investors, so there are strong reservations around that term, and it makes sense many investors would gravitate towards a new one. Before cleantech, the term was greentech, which goes to show that tech vocabulary is dynamic. However, “cleantech” and “greentech” are somewhat nebulous. A strength of “climate tech” is that it signals a clarity of purpose around managing the havoc wrought on our climate by greenhouse gas emissions.

Why now?

 

A major underlying factor behind the surge of interest in climate tech is the rising public demand for climate action, as evidenced by youth-led climate movements around the world. Adults pay attention when teenagers sternly address the United Nations with messages like, “We are in the beginning of a mass extinction, and all you can talk about is money and fairy tales of eternal economic growth. How dare you!”

 

Naturally, the response to that sentiment from Silicon Valley and other tech hubs is to solve the problem with new technology and new business models...

 

That's obviously a bit glib, but there’s some value to that approach, even if it seems counter-intuitive. The global shift from an emissions-heavy economy to a presents a massive business opportunity for the companies and technologies who can aid with the transition. That dual monetary and moral imperative is a tough force to stop.
