What is Climate Tech : Latest in Tech

The climate crisis demands innovative solutions, and Climate Tech is rising to the challenge.

This rapidly evolving field encompasses technologies and services aimed at decarbonizing the global economy, mitigating the effects of climate change, and building resilience in a changing world.

This guide provides a comprehensive overview of the Climate Tech landscape, exploring its key sectors, driving forces, and the exciting potential it holds.

What is Climate Tech?

Climate tech encompasses technologies and services that enable decarbonization of the global economy.

Climate tech companies develop products and services that leverage these technologies to:

  • Mitigate climate change: This involves reducing greenhouse gas emissions, often by transitioning to renewable energy sources, implementing energy efficiency measures, and developing carbon capture and storage technologies.
  • Adapt to climate change: This focuses on building resilience to the impacts of climate change, such as extreme weather events, rising sea levels, and changing agricultural patterns.

Since addressing climate change requires transformation across all sectors, climate tech companies span a wide variety of end markets and business models.

Key subcategories typically converge around technologies addressing the main sources of global emissions, as defined in the Intergovernmental Panel on Climate Change (IPCC) reports:

1. Energy: This sector includes technologies focused on renewable energy generation (solar, wind, hydro, geothermal), distributed energy solutions, battery storage, and power grid optimization.

The decentralized nature of renewable energy technologies has disrupted the energy ecosystem, driving significant private and public investment.

Governments worldwide, including the US and the European Union, are enacting policies and providing incentives to accelerate the transition to a clean energy economy.

2. Transportation: While often associated with electric vehicle manufacturers, the transportation sector encompasses other modes, including rail, long-haul trucking, public transport, and air travel.

While passenger electric vehicles have gained traction due to decreasing battery prices and government incentives, other modes face greater challenges.

Hard-to-abate sectors like aviation require significant technological advancements. New entrants are experimenting with electric aircraft, but limited range and the need for entirely new carbon-free fuel sources like hydrogen pose hurdles for complete fleet replacement.

3. Industry: This sector includes emissions from heavy industries like metals, mining, cement, steel, and chemicals.

Decarbonization in this sector requires novel solutions, as traditional processes often depend on fossil fuels or require significant energy inputs.

Start-ups are focusing on alternative manufacturing and material science methodologies to reduce emissions. However, regulation and the need for industry-wide adoption pose significant challenges.

4. Buildings: The buildings sector includes emissions from energy consumption and embodied carbon associated with construction (extraction, transportation, manufacturing, installation, and end-of-life).

Exciting opportunities for decarbonization exist within the built environment, with start-ups focusing on:

  • Smart Building Software and Sensors: These technologies optimize energy consumption and improve building efficiency.
  • New Construction Techniques and Materials: Lower-carbon building materials and sustainable construction practices are being developed to reduce emissions throughout the building lifecycle.

5. Agriculture: Agriculture accounts for a significant portion of global greenhouse gas emissions, primarily from deforestation and livestock management. AgTech innovation offers promising climate solutions:

  • Precision Agriculture: This uses data analytics and technology to optimize farming practices, minimizing resource use and reducing emissions.
  • Regenerative Agriculture: This focuses on building soil health, improving water retention, and enhancing biodiversity, promoting carbon sequestration.
  • Sustainable Crop Farming and Livestock Management: These practices aim to reduce greenhouse gas emissions and improve resource efficiency in food production.

6. Carbon Tech: This emerging sector encompasses two main types of innovation:

  • Carbon Removal Technology: This includes technologies like Direct Air Capture (DAC), biochar, soil carbon sequestration, enhanced weathering, and Bioenergy with Carbon Capture and Storage (BECCS). These technologies aim to remove existing carbon from the atmosphere, playing a crucial role in achieving Net Zero goals.
  • Carbon Accounting Software: These platforms help businesses track their carbon footprint, monitor emissions reductions, and manage carbon credits, providing essential tools for achieving sustainability goals.

The Growing Climate Tech Market

The climate tech market has expanded rapidly in recent years, attracting significant investment from venture capitalists, private equity firms, and corporations seeking to capitalize on the opportunities in the sustainable economy.

  • Venture Capital Investment: Silicon Valley Bank estimated that venture capital (VC) investment in climate tech startups totaled $56 billion in 2021 across over 1,600 deals. Despite the market downturn in 2022, these numbers decreased only slightly, indicating continued interest in the sector.
  • Public and Private Financing: SVB also estimated that current, global annual financing for the energy transition is $3.5 trillion across both public and private, debt and equity. This would need to increase to $5.6 trillion per year to limit global average temperatures to 1.5 degrees of warming.

Climate Tech vs. Clean Tech: A Defining Distinction

Clean tech generally refers to all technologies mitigating environmental damage, while climate technology explicitly focuses on addressing climate change.

Clean technology can include technologies addressing air pollution, waste generation, and clean water. While there’s overlap, climate tech emerged as a distinct category in recent years.

  • Beyond Renewable Energy: While climate tech includes renewable energy and electric vehicle startups, it encompasses newer climate-specific sectors that didn’t exist during the early clean tech boom, most notably carbon tech.
  • Scaling and Innovation: New entrants into the established renewable energy and electric vehicle markets are now required to provide differentiated value-add related to scaling existing solutions or increasing the capacity and efficiency of current technologies.

The Talent Pool: Attracting Top Professionals

The climate tech sector is attracting top talent, driven by a desire to contribute to a more sustainable future.

Thousands of professionals from diverse fields, including R&D, engineering, software development, and business management, are seeking opportunities to make a positive impact.

  • The Appeal of Purpose: The promise of purpose and a higher calling to solve climate change is a significant driver for talent.
  • Growth and Innovation: Climate tech companies offer exciting opportunities for career growth and innovation, with a focus on developing cutting-edge solutions.
  • Investment and Funding: Increased investment in the climate tech sector is creating a robust ecosystem with opportunities for both start-ups and established companies.


The Climate Tech sector is at the forefront of the global effort to address climate change.

By harnessing innovation, technology, and collaborative action, Climate Tech holds the potential to create a more sustainable and resilient future for generations to come.

As the world transitions towards a greener economy, Climate Tech will play an increasingly critical role in shaping a more sustainable and equitable world.
