(CNN) Sen. Elizabeth Warren on Tuesday announced she would adopt Washington Gov. Jay Inslee's 10-year climate plan, while also expanding on his blueprint with a series of additional investments costing $1 trillion to offer additional protections to workers and help fund a radical transition of American infrastructure and industry away from fossil fuels.

The Warren proposal, which would cost $3 trillion total, was released on the eve of a CNN town hall focused exclusively on the climate crisis . The Massachusetts senator is one of 10 2020 Democratic primary candidates scheduled to take questions Wednesday night on their environmental plans.

Warren's announcement signals her hopes of picking up the climate change baton from Inslee, who dropped out of the race on August 21, the same day he released the final piece of his comprehensive plan. In a Medium post published Tuesday night, Warren also challenged her rivals to meet Inslee's standard.

"Jay didn't merely sound the alarm or make vague promises. He provided bold, thoughtful, and detailed ideas for how to get us where we need to go, both by raising standards to address pollution and investing in the future of the American economy," Warren wrote. "While his presidential campaign may be over, his ideas should remain at the center of the agenda."

Inslee, who initially entered the primary focusing exclusively on climate change, departed with a reputation as one of the party's leaders on the issue. Warren and Inslee met in Seattle last weekend, aides to both told CNN, and discussed climate policy. Warren told Inslee in that meeting that she would be endorsing his plan.
