(CNN)President Joe Biden unveiled a roughly $2 trillion jobs proposal focused on infrastructure and the climate crisis in a speech in Pittsburgh on Wednesday, stressing his support of labor unions and his hope the investment would lift the middle class.The President’s next major legislative push, the American Jobs Plan, would heavily invest in rebuilding the nation’s crumbling infrastructure and shift to greener energy over the next eight years.

Biden plans to pay for his proposal by raising corporate taxes and eliminating tax breaks for fossil fuels, which was one of his core campaign promises. The White House says this tax hike would raise more than $2 trillion over the next 15 years.”It’s not a plan that tinkers around the edges,” Biden said. “It’s a once-in-a-generation investment in America, unlike anything we’ve seen or done since we built the Interstate Highway System and the Space Race decades ago.

“Biden made the case the spending would pay for desperately needed upgrades for roads and bridges as well ports and airports — all while helping to reduce climate change.”It’s the largest American jobs investment since World War II.

It’ll create millions of jobs, good paying jobs, it’ll grow the economy, make us more competitive around the world, promote our national security interests and put us in a position to win the global competition with China in the upcoming years,” Biden said.”It’s big, yes. It’s bold, yes. And we can get it done,” he added.
