WASHINGTON — This week, President Biden announced that Lael Brainard, the vice chair of the Federal Reserve who is known for citing the financial risks posed by climate change, would become his top economic adviser.
Her appointment follows that of Richard Revesz, an environmental lawyer and an academic who is known for defending climate regulations, who last month became head of the White House’s top regulatory office — a place that has historically been viewed as the place where environmental controls go to die.
The appointments to two of the most powerful posts in the White House underscore how Mr. Biden has pursued an “all-of-government” approach to climate change, appointing people with backgrounds in climate policy to senior positions across federal agencies. It also illustrates his intent to use executive action to address global warming in the last two years of this term.
“This is a new thing that we’ve seen from the Biden White House as they have made climate central to their economic recovery and regulatory agenda,” said Jamal Raad, executive director of the climate advocacy group Evergreen Action. “Putting people in positions of power that are not traditionally climate positions who deeply understand the climate crisis and the need to act on it.”
The White House did not respond to requests to interview Ms. Brainard or Mr. Revesz.
The timing of their appointments is not a coincidence. While Democrats in Congress passed the nation’s first major climate law last year, the midterm Republican takeover of the House of Representatives means it is unlikely that new environmental legislation will be enacted in the remainder of Mr. Biden’s first term. That leaves Mr. Biden with executive authority as a way to push through the rest of his climate agenda.
That will entail the oversight of about $370 billion in new spending on climate and clean energy programs provided by last year’s Inflation Reduction Act. It will also mean writing new climate regulations, intended to ratchet down emissions from cars, trucks, power plants and oil and gas wells.
In some ways, Ms. Brainard’s appointment as head of the White House’s National Economic Council, where she is expected to play a key role in the implementation of the Inflation Reduction Act, can be seen as a continuation of the way in which Mr. Biden views climate change as central to economic policy. Her predecessor on the council, Brian Deese, was previously a senior climate change adviser to former President Barack Obama.
The appointment of Mr. Revesz to his new post, however, is pathbreaking. The Office of Internal and Regulatory Affairs, an obscure but powerful agency within the White House, is designed to vet all proposed federal regulations and balance the demands of protecting health, safety and the environment against the cost to industries. In his new role, Mr. Revesz becomes the effective gatekeeper for all new federal regulations — including any new climate rules, many of which he has spent his career supporting.
That’s exactly what opponents of Mr. Biden’s climate agenda fear.
“For folks who want to litigate against the Biden administration, this is bad news,” said Jonathan Adler, a law professor at Case Western Reserve University.

Keeping the Keeling curve going. The eruption of Mauna Loa in Hawaii last year threw a six-decade-long survey of atmospheric carbon dioxide into crisis. It took a transoceanic scramble, and a dose of luck, for scientists to restart their measurements — on the next volcano over.
Frank Macchiarola, senior vice president for policy and regulatory affairs at the American Petroleum Institute, which lobbies for oil and gas companies, said he feared that Mr. Revesz “will approach this through the lens of an advocate, as he did in his prior work, and not as an objective regulator.”
Mr. Revesz, who grew up in Argentina and who is known as Ricky to everyone from his law students to his legal opponents, came to the White House from his role as an environmental law professor and dean emeritus of New York University Law School. He is also the co-founder of an N.Y.U.-affiliated think tank, the Institute for Policy Integrity, which is known for its innovative approach to analyzing the costs and benefits of environmental regulations. He played a key behind-the-scenes role in legal challenges to President Donald J. Trump’s dismantling of clean air and water rules.
Historically, such cost-benefit analyses of regulations have been based on the current economic cost to polluting industries. But Mr. Revesz has argued that regulations — particularly those related to climate change — should also take into account the cost of pollution on future generations. That approach can be used to justify strong climate regulations.
Mr. Revesz, 64, may be the first head of the White House regulatory office who is deeply familiar with both the nation’s premier scientific assessment on climate change and its potent legal power for defending environmental regulations.
When the Trump administration, despite its zeal for rolling back environmental regulations, was forced to release the 2018 National Climate Assessment, a sweeping report by 13 federal agencies that describes the devastating impact of climate change on the nation’s economy, Mr. Revesz spotted the legal implications of the document.
“This report will be used in court in significant ways,” he said in an interview at the time. “I can imagine a lawyer for the Trump administration being asked by a federal judge, ‘How can the federal government acknowledge the seriousness of the problem, and then set aside the rules that protect the American people from the problem?’”
That expertise later put Mr. Revesz on Mr. Biden’s short list to head the Environmental Protection Agency and on his transition team for the agency.
In some ways, Mr. Revesz’s background puts him at odds with the mission of the regulatory office that he now runs, which was created in 1970 by President Richard Nixon to serve as a check on the E.P.A. Historically, the office has blocked, watered down and delayed regulations for economic, political or other reasons.
“This office has always been about: You need to do less because of the economic cost,” said Richard Lazarus, an environmental law professor at Harvard who worked on the Biden transition team with Mr. Revesz. “Ricky might be the first to say, ‘You need to do more.’”
While Ms. Brainard’s new brief is less explicitly about ushering in climate policies, her approach to the financial risks of global warming is expected to deeply inform her leadership of the National Economic Council.
In her tenure on the Federal Reserve, Ms. Brainard, 61, gained notice as she called on regulators to consider the financial hazards posed by extreme weather, wildfires, drought, destruction and migration caused by climate change.
In 2019, Ms. Brainard spoke about “Why Climate Change Matters for Monetary Policy and Financial Stability” at the Fed system’s first climate conference.
“That 2019 event, where she was the key speaker, was really the first time the leadership talked about it,” said Sarah Dougherty, a former staff member at the Federal Reserve Bank of Atlanta and is now at the Natural Resources Defense Counsel, an advocacy group. “It wasn’t hidden, it wasn’t subtle, it wasn’t about ‘the weather.’”
Ms. Brainard’s attention to climate dates to her work as under secretary in the Treasury Department in the Obama administration, where she promoted a plan to ensure that the administration would no longer contribute to coal projects financed by the World Bank and other international development banks.
People who have watched her in her current role said that Ms. Brainard, an economist by training, would bring a depth of knowledge and an appreciation for the real-world effects of climate policy to the White House.
“She could bring a lot of insight,” Ms. Dougherty said.
