Four Twenty Seven provides market intelligence and climate data analytics to enable investors to integrate climate risks into portfolio management and investment decisions. Building on our award-winning work assessing climate risks in corporate facility portfolios and supply chains, we have expanded our capabilities to serve portfolio managers and asset owners in the financial sector. We help investors understand which assets may be exposed to the physical impacts of climate change, identify opportunities to tilt portfolio composition towards less exposed assets, and meet emerging regulatory requirements under the TCFD to disclose exposure to the physical impacts of climate change.

We have worked with Fortune 100 companies and some of the largest institutional investors in the world, and understand the needs, constraints, and opportunities of bringing climate analytics into business planning and strategic investments in large corporations.

Some sectors are particularly vulnerable to climate change. Healthcare, agriculture, and food will see extensive, complex, and diversified impacts from climate change. Agriculture is vulnerable to even small changes in precipitation, temperature, or seasons, which can affect crops, soils, or growing regions. Humans respond differently to extreme climatic conditions based on demographics, medical conditions, social vulnerability, and adaptive capacity, with implications for their well-being.

Four Twenty Seven leverages its powerful data analytics to model and deepen our understanding of the sector-specific impacts of climate change. Our work on healthcare has won multiple awards and is helping California and Federal agencies deepen their understanding of the medical and social implications of heat health events and develop customized policy responses at the local level.

The most sensitive sectors also stand the most to gain from new market opportunities. Whether looking for water efficiency improvements in food processing or mapping long-term trends in sales of consumer products connected to the volatility of weather trends, we believe robust climate intelligence will support better investment decisions and long-term adaptation.
