AGL has continued to be a leader in  advocating the introduction of a price  on carbon emissions. Policy uncertainty  surrounding carbon pricing is affecting  investment in new power generation  capacity, with unnecessary additional  costs to electricity users. AGL is assisting government in its  deliberations on the optimal approach  to reducing greenhouse gas emissions  and on delivering certainty for investors  in the energy supply sector. Our goal is to invest in cleaner energy forms to reduce the  greenhouse gas intensity of energy across the supply chain. Minimising  carbon risk 20 Sustainable  Business Strategy Climate  Change
