Risks that Require Monitoring • Well-bores and their integrity • Water injection (hydraulic fracturing), extraction and storage • Air quality and noise levels • Traffic of vehicles
Better Practices • Full community engagement over local concerns (land access protocolos, disclosure, etc.) • Effective risk management (venting of gas, water management, etc.) • International Energy Agency (IEA) estimates that adopting Best Practices would increase costs of production by only about 10%
CO2 Emissions during Electricity Generation (grams per kWh) Source: IGU 2012
Reductions in CO2 Emissions • IEA estimates that with ‘Golden Rules’ in terms of unconventional gas production with adequate environmental practices in place global CO2 emissions would be 1.3% less in 2035. • Globally, substitution of coal and oil by gas would projected to reduce global CO2 emissions by 740 Mt in 2035 • In Australia, if gas substituted one-for-one for reductions in coal-fired electricity generation and based on BREE’s long-term energy projections by 2035 would have 15% less CO2 emissions in electricity generation sector.
