FedEx pledges $2 billion to become carbon-neutral by 2040

• Amazon, which overlaps with FedEx in some ways, announced a target of net-zero by 2040 in 2019.

How it works: FedEx said one focus will be electric vehicles.

• It hopes to have its parcel pickup and delivery fleet fully electrified by 2040, with interim goals like making 50% of new vehicle purchases electric by 2025.
• Elsewhere, it's emphasizing less polluting aviation fuels, more efficient planes, making its thousands of buildings more efficient and buying more renewable power.

The intrigue: FedEx is also looking to expand the use of natural carbon sequestration systems.

• It's giving Yale University $100 million to launch the Yale Center for Natural Carbon Capture that the school unveiled this morning.
• The center aims to "develop interventions that enhance the Earth’s abilities to store carbon and other methods that model natural processes," the announcement states.

How it works: Natural carbon sequestration means a lot of things. The announcement notes areas like...

• Increasing CO2 update via practices like protecting growing new forests, more efficient photosynthesis, soil and farm management techniques, boosting earth's natural CO2 absorption in rock formations, and more.
