There are more than 13 billion reasons why the climate package unveiled on Sunday is better at putting a price on pollution than its predecessor.
For starters, there's $10 billion for renewable energy projects. Unlike the Carbon Pollution Reduction Scheme (CPRS) proposed by the former Rudd government, this package lays the basis for science-based climate action.
The old scheme locked in weak targets for 15 years which could not be strengthened. There was no money for investment in renewable energy and next to nothing for energy efficiency measures.
