Maritime businesses can expect support from London’s finance sector for investment in decarbonisation initiatives due to the scale of the opportunity, the City's mayor has pledged.

Alderman William Russell said London’s financial and professional services sector was prepared to back investment in both hardware and software to help accelerate cuts to shipping’s carbon footprint.

The City’s financial sandbox for experimenting with new products and services showed the sector was able to help businesses develop new opportunities, said Russell, a financier who is the top official in the section of central London that houses much of its financial services industry and key shipping institutions.
