The Cost and Hope of a Green Transition: Trillions Needed, Billions Pledged, and a Global Guide to Electric Grid Development.

The shift to a low and zero carbon future will require cutting edge technological innovation alongside huge levels of investment. According to the International Energy Agency, clean energy investment will need to hit over $4 trillion a year by 2030 in its Net Zero Emissions by 2050 Scenario. Reaching this kind of figure will require a huge effort from both the public and private sector. Mark Dooley, global head of Macquarie Asset Management's Green Investment Group, believes that the investor appetite to be part of this transition is enormous, and the money will be there as soon as we can produce the projects.
