The world will need to invest up to $173 trillion in greener energy infrastructure and supply over the next 30 years if it wants to achieve net-zero carbon emissions by 2050, BloombergNEF said in its New Energy Outlook 2021 report published on Wednesday. If governments and companies want to see the coveted 2050 net-zero emissions they have been racing to pledge in recent months, they would need to invest between $92 trillion and $173 trillion in the next three decades, according to BNEF. The energy transition that would be compatible with a net-zero world in 2050 would need rapid scaling of investment, the research firm says, adding that “the route to net-zero remains yet uncertain.” According to BNEF, the world needs to more than double yearly investments in order to achieve net-zero emissions. Those investments should jump from around $1.7 trillion annually at present to “somewhere between $3.1 trillion […]
