FACTBOX-Australia's biggest carbon emitters

CANBERRA, March 2 (Reuters) - Australia's Climate Change Department has released a list of the country's biggest greenhouse gas emitters, pointing to companies which may be included in the government's carbon trade plans.

Power generators dominate the list, along with big mining companies and aluminium and steel smelters.

The government wants carbon trading to start in July 2011 covering the top 1,000 polluters and forcing them to buy or receive free permits for every tonne of carbon they emit.

But the plan is stalled in parliament's upper house Senate, where it has been rejected twice and faces a third defeat in May.

The figures, in million tonnes of CO2-equivalent, are based on Scope 1 emissions, for the year to June 30, 2009.

Scope 1 emissions are directly produced by an operation, such as a power plant or the making of cement.
COMPANY NAME (PARENT COMPANY) Emissions


Macquarie Generation (State owned) 25.29
Delta Electricity (State owned) 22.23

Great Energy Alliance Corp Ltd (AGL Energy Tokyo Electric Power Co,
private investors) 18.96

International Power (Australia) Holdings Ltd
(International Power) 17.97
CS Energy Ltd (State owned) 16.63
TRUenergy Holdings Ltd (CLP Holdings,) 15.83
Eraring Energy (State owned) 13.25

Electricity Generation Corp (Stated-owned Verve Energy) 10.97
Loy Yang Holdings Ltd (International Power,) 10.14
Woodside Petroleum 8.20
Babcock and Brown Power Ltd (Alinta Energy) 8.04
NRG Victoria 1 Ltd (NRG Energy Inc) 8.02
BlueScope Steel 7.95
Rio Tinto Ltd 7.62
Stanwell Corp Ltd (State owned) 7.28

Alcoa Australian Holdings Ltd
(Alcoa Inc, Alumina Ltd) 6.85
Tarong Energy Corp (State owned) 6.71
AZSA Holdings Ltd (Xstrata) 6.55
BHP Billiton Ltd 5.06
Qantas Airways Ltd 4.01

The list also includes scope 2 emissions for companies. These emissions are a direct result of one or more activities that generate electricity, heating, cooling or steam consumed by the plant but do not form part of the plant.

Alcoa, which operates its own coal-fired power plant south of Melbourne, has Scope 2 emissions of 10.66 million tonnes; Rio, which has a stake in a large power plant in Queensland, has Scope 2 emissions of 9.39 million tonnes.

But the climate change department cautions against using the figures individually or to add them together to calculate a company's potential liabilities under the government's carbon pollution reduction scheme (CPRS). Emissions subject to the CPRS apply only at certain thresholds.
