Carbon Pollution Reduction Scheme Bill
3(2) The first object of this Act is to give effect to Australia’s obligations
under:
(a) the Climate Change Convention; and
(b) the Kyoto Protocol.
(3) The second object of this Act is to support the development of an
effective global response to climate change.
(4) The third object of this Act is:
(a) if Australia is a party to a comprehensive international agreement
that is capable of stabilising atmospheric concentrations of
greenhouse gases at around 450 parts per million of carbon dioxide
equivalence or lower—to take action directed towards meeting
Australia’s target of reducing net greenhouse gas emissions to 25%
below 2000 levels by 2020; and
(b) if paragraph (a) does not apply—to take action directed towards
meeting Australia’s targets of:
(i) reducing net greenhouse gas emissions to 60% below 2000 levels
by 2050; and
(ii) reducing net greenhouse gas emissions to between 5% and 15%
below 2000 levels by 2020; and
(c) to take the action mentioned in paragraph (a) or (b) in a flexible and
cost-effective way.
Carbon Pollution Reduction Scheme Bill Revised
Explanatory Memorandum
Government considers that a comprehensive international agreement
will involve inter alia:
• a clear global trajectory, where the sum of all economies’
commitments is consistent with 450 parts per million CO2-e or lower,
and with a nominated early deadline year for peak global emissions
not later than 2020
• advanced economy reductions, in aggregate, of at least 25 per cent
below 1990 levels by 2020
• major developing economy commitments to slow growth and to then
reduce their absolute level of emissions over time, with a collective
reduction of at least 20 per cent below business-as-usual by 2020
and a nomination of a peaking year for individual major developing
economies
