Yes, 2024 has not been the most favorable year for the climate tech industry in terms of politics, investment, and startup success stories. If you follow dominant media, it even seems like climate change and biodiversity loss are merely side topics compared to wars, elections, AI, and Bitcoin. These issues dominate headlines—and not without reason—but the hard truth remains: climate change and biodiversity loss are the most foundational threats to humanity.

The Stakes Have Never Been Higher

In 2023, the Intergovernmental Panel on Climate Change (IPCC) released yet another stark report reminding us that global temperatures are on track to rise by more than 2°C by the end of the century unless drastic action is taken. This temperature increase would lead to catastrophic consequences:

  • Rising sea levels
  • Devastating natural disasters
  • Widespread biodiversity loss

In 2024, the World Bank reported that global investment in climate solutions fell short by over $200 billion compared to the amount needed to stay on course for net-zero goals.

Despite these sobering statistics, there is a clear plan of action: transform industries like energy, food, transportation, materials, housing, and finance to achieve net-zero emissions and nature-positivity by 2050. Otherwise, the challenges we face today will only intensify, impacting not just the economy but the very fabric of our existence.

Climate tech and nature tech are the most direct ways to enable this transformation. They harness entrepreneurship and cutting-edge innovation to tackle the root causes of our environmental crises. For example, 2024 saw significant advancements in renewable energy storage technology, such as solid-state batteries, which could revolutionize the way we store and use clean energy. Meanwhile, nature-based solutions like reforestation drones and AI-powered biodiversity monitoring systems continue to gain traction as essential tools for restoring ecosystems.

Climate tech and nature tech are the most direct ways to enable that industrial transformation, especially through entrepreneurship that leverages all the amazing technological advancements we are witnessing. It's not just about putting out a fire, i.e., managing a crisis. It's also an opportunity to upgrade humanity to become a planetary species—a species sustainably embedded in its habitat.

You think the term "climate tech" is dead, just like "cleantech" became outdated? Go ahead and give it a new name—but don't undermine what it stands for. It's easy to criticize approaches that are not yet established and, therefore, fail in various ways. Be different. Be courageous. Take a closer look at the failures and build something based on what you've learned from them.

Learning from Failure to Build a Better Future

Failure is often inevitable when pushing boundaries—but it's also invaluable. As someone who attempted to build a nature fintech startup in 2024, I can attest that failure is a bitter pill to swallow. However, it's also a profound teacher. Each setback highlights gaps in our strategies, systems, or execution, offering critical lessons for the next wave of innovation.

I would like to be courageous. Yes, last year I failed in my attempt to build a nature fintech startup. It was not pleasant, but I forgave myself. However, I could never forgive myself for giving up on climate tech and nature tech altogether, as that would be untruthful. Because for me, the truth is that this is a do-or-die, thrive-or-perish issue. What else could I possibly be working on?

The term "climate tech" may seem outdated to some, just as "cleantech" did a decade ago. But what matters isn't the label; it's the mission. We need courageous entrepreneurs, investors, and innovators who are willing to learn from past failures and keep moving forward. As the late philosopher Friedrich Nietzsche said, "(S)He who has a why to live can bear almost any how." Our "why"—preserving the planet and ensuring a sustainable future—couldn't be more compelling.

Why 2025 Is a Pivotal Year

The year 2025 could mark a turning point for climate tech and nature tech. Key developments include:

  • Governments implementing stricter emissions regulations
  • The Inflation Reduction Act in the United States funneling billions into clean energy projects
  • The European Union's Green Deal Industrial Plan accelerating investments in renewable energy and sustainable manufacturing

Moreover, public awareness about climate change is growing, particularly among younger generations. A 2024 Pew Research Center study found that 68% of millennials and Gen Z view addressing climate change as a top priority, compared to just 46% of baby boomers. This generational shift in values is driving demand for sustainable products and services, creating new market opportunities for climate-focused startups.

A Call to Action

This isn't just a blog post; it's a call to all those smart, skilled, and hardworking people in my network to ask themselves: What else should I be working on? Climate tech and nature tech offer unparalleled opportunities to make a difference—to address the most pressing challenges of our time while building a more sustainable and equitable future.

Let's make 2025 a year of action and innovation. Let's embrace the lessons of 2024, take bold steps forward, and show the world that a better future is possible. After all, the rest will follow when we have a compelling "why" guiding our efforts.

Let's make 2025 a good year for climate tech and nature tech.
