As delegates arrived at the Republican National Convention in Milwaukee earlier this week to officially nominate former president Donald Trump as their 2024 candidate, a right-wing policy think tank held an all-day event nearby. The Heritage Foundation, a key sponsor of the convention and a group that has been influencing Republican presidential policy since the 1980s, gathered its supporters to tout Project 2025, a 900-plus-page policy blueprint that seeks to fundamentally restructure the federal government.

Dozens of conservative groups contributed to Project 2025, which recommends changes that would touch every aspect of American life and transform federal agencies—from the Department of Defense to the Department of Interior to the Federal Reserve.

Two summers ago, Biden also signed the Inflation Reduction Act, the biggest climate spending law in U.S. history with the potential to help drive greenhouse gas emissions down 42 percent below 2005 levels.

“It’s real bad,” said David Willett, senior vice president of communications for the environmental advocacy group the League of Environmental Voters. “This is a real plan, by people who have........
