Methane, combustion for power generation, NT {AU}| | AusLCI, U
Unit process Australia v00.00.000
Included processes:process begins with the combustion of methane and ends with the generation of electricity and includes emissions from the electricity and offsets of grid electricity. Remark: The credit for electricity generation is applied to be compliant with the AusLCI guidelines which in turn use EN 15 804 methodologies for end of life recycling and energy recovery. Geography: Refers to an average production in the Australia. Technology: Average Time period: Data collected for 2012 Version: 1.0 Record: Data entry by: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU Generator: Data entry by: Tim Grant Telephone: 0061 408104977; E-mail: tim@lifecycles.com.au; Company: LCS; Country: AU
