Elizabeth Warren has ascended in recent Democratic presidential polls atop a growing stack of audacious proposals to wipe out student debt, break up giant companies like Amazon and Facebook, and slap new taxes on the ultra-rich.

Yet the senator from Massachusetts is taking a different approach to the climate crisis , weaving a patchwork that will likely amount to Warrens answer to the Green New Deal .

In February, Warren co-sponsored the Green New Deal resolution that Sen. Ed Markey (D-Mass.) and Rep. Alexandria Ocasio-Cortez (D-N.Y.) introduced. In April, Warren released a public lands plan, promising to sign executive orders to ban new fossil fuel leases on federal acres and demarcate more areas for renewable energy. In May, she outlined a plan to dramatically slash emissions generated by the U.S. military, one of the worlds biggest polluters.

On Tuesday, the Warren campaign released its most comprehensive climate plan yet, a $2 trillion package that commits the federal government to spend $150 billion a year over the next decade on low-carbon technology, increases energy research funding tenfold and funds a $100 billion Green Marshall Plan to aid the poorer countries projected to suffer the worst as global temperatures rise.

In modeling her proposals on the post-World War II Marshall Plan aid package that helped rebuild Western Europe, Warren takes stock of the global nature of the crisis.
