Governments and companies need to spend an extra $34 trillion on the clean energy transition between now and 2050 to reach net-zero emissions, according to BloombergNEF.
The research group’s 250-page New Energy Outlook report, which crunches 18 million datapoints, says that amount is 19% more than what’s expected in its base case scenario. The finding indicates that sectors from electric vehicles and renewable energy to power grids and carbon capture need extra support.
The clean energy transition has faced resistance in recent years as climate policies have become a political flash point across the US and Europe. At the same time, renewable project developers have come up against higher interest rates and inflation, making the potential return on investments less attractive.
While BNEF earlier this year said global investment in the low-carbon energy transition surged 17% in 2023 to $1.8 trillion, its report Tuesday shows the pace of this spending needs to accelerate as the world continues to warm and bigger solutions are needed sooner.
“It is somewhat encouraging that we’re so near, but at the same time, it’s also so far because a lot of these investments aren’t fully profitable without further action,” said David Hostert, global head of economics and modeling at BNEF.
BNEF split its analysis between two scenarios.
- Its base case sees governments relying solely on economically competitive technologies, putting the world on course to warm 2.6C from pre-industrial times. This pathway, dubbed the economic transition scenario (ETS), is still slightly better than what governments are currently committed to doing, but it would lead to catastrophic climate impacts as the world breaches the 2C goal set under the Paris Agreement.
- Its net-zero scenario (NZS) assumes governments double down on emissions-reducing technologies with an aim to reach net zero by 2050. If the world follows this path, it still might miss the more ambitious Paris goal of keeping warming below 1.5C — edging closer to 1.75C instead. That could still avoid some irreversible climate damages.
 Among the big step changes needed to achieve net zero, the report says every new car sold from 2034 onwards will have to be an electric vehicle. Carbon capture technologies will require $6.8 trillion worth of investment to trap emissions not just from industry, but also the power sector. Power grid projects investments will peak at about $1 trillion per year in the 2040s — similar to the investment required for renewable energy generation in that decade.
“There’s definitely a wake up in national grid companies, but the investment isn’t moving as quickly as it should.” Hostert said.
