The world faces an existential threat from climate change

The root cause of climate change is the buildup in the atmosphere of greenhouse gases from human activities, such as energy generation, transportation, industrial, and agriculture activity. These gases trap heat and warm the planet, which leads to increased volatility and severity of heat, drought, storms, floods, and wildfires. These weather events lead to societal disruption, such as displacement of people from their homes, power outages, supply-chain disruptions, and food insecurity.

The effects of climate change are accelerating. The past five years have been the hottest five on record. In 2020, we saw record wildfires in Australia and California, a record number of named Atlantic storms, and record water levels in parts of Europe and China. In May 2022, temperatures in New Delhi reached 49°C (120F). According to the United Nations Intergovernmental Panel on Climate Change (IPCC), the world will reach an irreversible tipping point if the increase in global temperatures cannot be limited to 1.5°C, a level that would require “rapid and far-reaching” transitions in land, energy, industry, buildings, transport, and cities. The latest projection from the World Meteorological Organization implies a 50% risk that the global temperature temporarily reaches that threshold in the next five years.

We believe addressing climate change requires a two-pronged approach. As society implements measures to mitigate the cause of climate change by reducing greenhouse gas (GHG) emissions, governments, businesses, and consumers need to adapt to become resilient to the extreme weather events we are already experiencing. 

The demand for capital is enormous and necessary

The challenge is clearly daunting. But that also means that the market opportunity for mitigation- and adaptation-related climate solutions is enormous and necessary. While some individuals and companies may be willing to make trade-offs for more climate-friendly solutions, it is unlikely that society will accept trade-offs at the scale needed. People are unlikely to stop traveling and consuming, and businesses are unlikely to stop producing. Regulation will be essential, but, ultimately, we think solutions will need to be market-driven and stand on their own to be truly scalable.

In our view, this creates an enormous opportunity for innovations and technology that address climate change while delivering a superior user experience without trade-offs. We see all of this reflected in the growth of climate-related investments across public and private markets. This includes investments in venture-backed start-ups that we think will be instrumental in developing many of these solutions. To do so at scale will likely require substantial growth capital as illustrated by recent, global deal activity in private climate tech, an area in which many of these emerging climate solutions providers operate

The range of investable climate solutions continues to broaden and expand

Cost declines and increased market adoption are continuing in well-known areas such as renewables and electric vehicles and are likely to expand with ongoing scientific and technological innovation, for example, advances in solar materials and battery technology. These developments will be critical to the evolving market, but they also tend to be asset heavy and capital intensive.

Fortunately, there are also less capital-intensive solutions involving the application of existing technologies in end markets, which can drive efficiency while also reducing GHG emissions or increasing resilience to climate change. Sensors, connectivity, computing/analytics, artificial intelligence, and enterprise software and financing models, for example, can lead to smarter buildings and homes, connected and flexible energy grids, optimized manufacturing and supply chains, and new distribution and business models in the food and apparel sectors. Many of these business models help mitigate climate change not just by greening the supply of consumables but also by changing and optimizing demand.

Regarding adaptation, improved near-term weather and longer-term climate forecasting should help companies adjust their operations in real-time to account for extreme weather events and to incorporate future climate risk into long-term asset planning. Parametric weather insurance is emerging as a way for businesses and consumers to hedge their revenue or asset risk around weather-related risks. Together, we believe these combine into a wide range of potentially high-return, high impact opportunities, particularly within growth stage, climate tech companies. 

At the same time, investors should not overlook that investing in these more illiquid private companies comes with specific risks and is therefore only appropriate for investors who can take a long-term approach as exiting an investment in the event of financial or sustainable underperformance may be hard to accomplish. Overall, transparency and governance may be more limited compared to investments in publicly listed companies. Moreover, some of these management teams may have less experience with public shareholder scrutiny and engagement than existing public companies. 

Investors also need to ensure that the investee companies ultimately deliver real-world solutions in the fight against climate change, meaning rigorous measurement of actual impact is critical, both when identifying and monitoring investments.
