He says it's permanent funding.

State Senate President Pro Tem Darrell Steinberg has a new plan for affordable housing and mass transit.

The senate leader says using money from the state's cap-and-trade program can help tackle both issues at once and fight off global warming.

Under a new proposal, the billions raised from emission permits would be go towards housing projects near new transit options and be diverted into large projects like high-speed rail.

"State funding for affordable housing was eliminated almost entirely during the global recession. The funding shortfall for mass transit between 2011 and 2020 is $22 billion," Steinberg said. 

The idea is a shift away from a "gas tax" proposed earlier this year. Steinberg also wants cap-and-trade money made available to water efficiency, electric vehicles and recycling.
