Four Twenty Seven is headquartered in Berkeley, California with offices in Washington, DC and Paris, France. It is an organisation that provides climate risk data that measures the physical risks of climate change, and the exposure of corporate production and retail sites to climate change hazards, which ultimately have an impact on investment portfolios. Four Twenty Seven was founded by a single individual, Emilie Mazzacurati, and is led by a team of highly qualified professionals with backgrounds in finance, computer engineering, macroeconomics, climate science, international development, natural resources management, and policy analysis. Parent to this organisation is Moody’s Investor Service, the bond credit rating agency of Moody’s Corporation, which acquired Four Twenty Seven on 24th July 2019.

The main objective of the organisation is to bring attention to the risks of climate change and specifically the risks associated with being unprepared for potential climate change hazards, such as droughts and sea-level rise, given that even the most powerful financial institutions can be brought down to its knees as a result of the devastating consequences of these hazards. A direct link to its purpose is in the name of the organisation itself, Four Twenty Seven, is a reference to California’s previous 2020 emissions target, 427 million tonnes of carbon. Their solutions which enable them to provide insights into the risks of climate change include on-demand analytics and data products, providing award-winning climate risk scores for listed instruments in equities and fixed income markets. Such insights have the purpose of informing investors and clients in constructing their investment portfolios.
