Fidelity International, State Street, Amundi and Schroders are among a group of more than 400 influential investors that have called on the world’s most powerful nations to “raise ambition and accelerate action” to tackle the climate crisis.

The group of 457 investors, which oversees more than $41tn in assets, has issued a statement to the G7 — Canada, France, Germany, Italy, Japan, the UK and US — demanding urgent action to reduce greenhouse emissions and limit global warming to 1.5°C, as set out by the Paris Agreement in December 2015.
