    The waste sector can contribute to achieving the ACT’s
    greenhouse gas reduction targets and the long term
    goal of zero net emissions by 2060. Options include
    improving methane capture from landfill, minimising
    organic waste to landfill, exploring energy from
    waste technologies to produce power and sequester
    carbon, increasing recycling to avoid greenhouse
    gas emissions, and ensuring energy efficient waste
    collection and processing.
