How the Inflation Reduction Act will affect the green transition: Experts

President Biden signed the Inflation Reduction Act (IRA) into law last week, mobilizing $369 billion in climate spending.

"This bill is the biggest step forward on climate ever — ever," Biden said in a speech. "And it’s going to allow us to boldly take additional steps toward meeting all of my climate goals — the ones we set out when we ran."

Experts and climate scientists roundly cheered the bill as a key step to curb emissions and fight climate change but noted there is still work to do.

“Getting to net zero is something that I think we can all see we're on a path to,” Josh Griffin, co-founder and chief policy officer at nZero, told Yahoo Finance.

The policy package comes with a number of tax breaks for clean energy, with $51.1 billion allocated for renewable energy production, $50.9 billion for clean electricity investment, $30 billion for nuclear production, and $3.2 billion for carbon capture technologies.

It also includes some novel features like a fee on methane gas emissions and $27 billion for the Greenhouse Gas Reduction Fund — essentially a green bank that lends money to startups that can help decarbonize the economy.

The Inflation Reduction Act also includes environmental justice initiatives including incentives to install solar and wind in low-income and disadvantaged communities as well as drought mitigation funding to help parts of the U.S. suffering under water restrictions and extreme temperatures linked to climate change.

Griffin highlighted the "totality" of the IRA and how its approach includes a variety of industries beyond the energy sector.

“More steps will need to be taken,” Griffin added, “but this to me, the Inflation Reduction Act, is just the start, and it's engaging the market, it’s engaging investors, it's engaging banks, it’s engaging equity, it's engaging policymakers, it's engaging manufacturers, and those build on themselves and will only improve.”

Green transition won't take place 'overnight'

Under President Biden, the U.S. set a target to achieve a 50-52% reduction in greenhouse gas emissions relative to 2005 levels by 2030 and reach net-zero emissions by 2050.

A preliminary analysis by independent research provider Rhodium found that the Inflation Reduction Act will get us closer to that goal with a 31-44% greenhouse gas reduction by 2030. On Thursday, the Department of Energy released similar estimates, forecasting a 40% reduction in emissions by 2030.

Amid the optimism, however, two analysts cautioned that the new legislation won't smooth every bump in the path to net-zero, especially as supply chains and inflation remain core concerns.
