(CNN) New York Democratic Rep. Alexandria Ocasio-Cortez and allied progressive groups are ramping up their push for a Green New Deal.

The initiative came to national prominence after Ocasio-Cortez joined young activists from the Sunrise Movement at a protest in then-Minority Leader Nancy Pelosi' s office during orientation for incoming House freshman last year.

Ocasio-Cortez, the Justice Democrats, a progressive group that recruited the Bronx-born New Yorker to run, and Sunrise are now poised to throw their organizing muscle behind the ambitious suite of policy proposals, which would move the country toward 100% renewable energy through a series of economic reforms, including a jobs guarantee and heavy public investment in low or no-carbon infrastructure like light rail for commuters.

Movement leaders do not agree on a price tag. Estimates run in the hundreds of billions of dollars, or more. But they argue a combination of tax hikes on the super wealthy -- Ocasio-Cortez has floated a 70% rate on income over $10 million -- and cuts to fossil fuel industry subsidies and military spending, in addition to the stimulative effects of the new public spending would offset any cost.

As part of the new outreach, organizers will train volunteers -- online and in-person at a series of events this spring -- to more effectively confront elected officials and ask for their support. The "Road to a GND Tour" was drawn up as a traveling pressure campaign designed to secure the support of political leaders, from mayors and city council members to federal lawmakers, around the country.
