London needs a 50% increase in public transport capacity within 35 years, according to Boris Johnson.
The mayor’s office published a response to a consultation held last year on the 2050 London Infrastructure Plan.
This initial document set out plans for more than £1 trillion investment in the capital.
Now the update has set out further details of what’s needed, including a 20% increase in energy supply and 40 new waste management facilities.
It added that a map showing all infrastructure building and refurbishment in the pipeline for the next five years, and how efficiencies could be achieved over the following 10 years, was in development.
This will allow officials to plot the next generation of infrastructure investments to meet predicted long-term demand, it added.
“We aim to share this information with infrastructure providers and boroughs and make a public version available by summer 2015,” said the report.
Institution of Civil Engineers London director Miranda Housden said: “The stark reality is that if London is to maintain its standing as a world class city, it needs world class infrastructure networks that are resilient and have sufficient capacity to accommodate the growing demands that will be placed on them.
“This requires long term commitment to invest in and improve London’s infrastructure in a sustainable way, and importantly, strategic direction. It is clear from the London Infrastructure Plan 2050 update that some positive steps have been made, and that the core issues are being tackled.
“We now look forward to seeing this vision translate into a plan. As London First points out, investing properly in London’s infrastructure could boost the capital’s economy by £1.9 trillion in the long term, and greatly benefit the UK as a whole - so there is much at stake.”
