In the time since this article was first published, McKinsey has continued to explore the topics it covers. Read on for a summary of our latest insights.
Net zero is a critical global imperative. But achieving it will come down to actions taken on the national, state, community, and even individual level. In pursuit of net zero, the United States passed the Inflation Reduction Act (IRA) in August 2022. In coming years, the IRA will direct nearly $400 billion in federal funding toward clean energy, with the goal of substantially lowering the nation’s carbon emissions by 2030—and reinvigorating America’s global economic competitiveness, innovation, and industrial productivity. The IRA is one of three major investment bills passed since November 2021; together, the IRA, the Bipartisan Infrastructure Law (BIL), and the CHIPS and Science Act (CHIPS) are projected to inject more than $2 trillion into the US economy.
What progress has been made since the IRA was signed into law? 2023 was spent primarily in the planning stages. The federal government drew up a variety of new programs and state governments launched coordinating bodies with the goal of winning federal grants and efficiently deploying funding.
2024 will mark a transition from planning to implementation. To establish the future American economy, leaders at the federal, state, and local levels can work with industry leaders on unlocking three specific challenges: complex service procurement timelines, supply chain shortages, and permitting restrictions.
How can states initiate or accelerate their decarbonization plans? We’ve identified three no-regrets moves.
- Understand the state’s current carbon footprint and potential for progress. This includes creating a comprehensive baseline of state emissions, enacting policies to reduce emissions, and setting metrics to monitor progress.
- Develop or update decarbonization pathways based on different scenarios, taking into account emerging technologies, supply chain challenges, workforce changes, and shifting policies.
- Coordinate with stakeholders on progress toward goals. This involves identifying skills and capabilities that could accelerate the transition, staying up-to-date on funding opportunities and emerging technologies, and staying accountable on efficient resource deployment.
Equity matters. The BIL, CHIPS, and IRA seek to redress long-standing inequalities by laying a stronger foundation for sustainable, inclusive growth. When making funding decisions, stakeholders at all levels should consider the needs of communities that have historically been underrepresented in shaping public works. These include people living in rural, low-income, tribal, climate-vulnerable, and other marginalized areas. To harness federal funds for these goals, state leaders could consider three actions: include a diverse range of stakeholders in decision making, provide targeted support to critical stakeholders pursuing grants, and take proactive steps to promote transparency in the investment process.

The Inflation Reduction Act of 2022 (IRA), signed into law on August 16, 2022, directs new federal spending toward reducing carbon emissions, lowering healthcare costs, funding the Internal Revenue Service, and improving taxpayer compliance.1
The act aims to catalyze investments in domestic manufacturing capacity, encourage procurement of critical supplies domestically or from free-trade partners, and jump-start R&D and commercialization of leading-edge technologies such as carbon capture and storage and clean hydrogen. It also allocates money directly to environmental justice priorities and requires recipients of many funding streams to demonstrate equity impacts. The Congressional Budget Office (CBO) estimates that the law will reduce budget deficits by $237 billion over the next decade.2
This is the third piece of legislation passed since late 2021 that seeks to improve US economic competitiveness, innovation, and industrial productivity. The Bipartisan Infrastructure Law (BIL), the CHIPS & Science Act, and IRA have partially overlapping priorities and together introduce $2 trillion in new federal spending over the next ten years.
Here’s a breakdown of the IRA’s major provisions—by the numbers.
