“Are Greenhouse-friendly Energy Strategies Lifestyle-friendly?” A Pears in Greenhouse and Energy CSIRO 1990
• “The impacts of well managed greenhouse-friendly energy strategies are likely to enhance, rather than detract from lifestyle quality….”
• “Successful greenhouse response will involve consideration of equity issues, and management of transitional impacts on the workforce and in the market place. Institutional action is required to complement and support individual response. This will involve shaping new industrial directions, restructuring financial and taxation signals, reallocating financial and physical resources to strategic activities, and empowering individuals to act.”
• My views haven’t changed…..
Since then, some successes• Appliance energy efficiency:
– labels since late 1980s, standards from late 1990s
• Residential building envelope improvement:– Victorian insulation regulations 1991, 5 Star
regulations 2005; ACT 4 star mid 1990s; national regulations (3-4 star) 2003, 5 star 2006
• Commercial buildings:– Demonstration high performance buildings– Proposed national building regulations 2006
• Industry:– Energy Efficiency Best Practice (Commonwealth)– EPA Victoria Greenhouse Program

Some worrying areas
• Overall energy growth trends
• Residential sector energy
• Commercial sector energy
• Some industry sectors
• Transport sector
• Energy market reform: incentives to sell more energy+ loss of support for DSM

To summarise:
• We know how to cost-effectively make large cuts in greenhouse emissions in every sector, and we have some practical successes
• In several major areas, significant initiatives are finally being introduced
• Progress is being slowed by a combination of powerful vested interest groups, narrow economic theorists and nervous politicians
• So why is action so difficult?
My interpretation of the situation
• People embrace change if they believe it will offer them benefits, but resist it if they fear adverse impacts
• Some industries concluded by 1990 that greenhouse action would hurt them
• They (helped by some misinterpretation of economic modelling results and ill-informed media) convinced most businesses that all business and the economy will be hurt by greenhouse response
• Economic policy people in government have generally accepted and promoted this view
• And the community is confused and disempowered
So future response is tied to beliefs about the relative costs and benefits of action
• Beliefs that response will hurt the economy are based on economic modelling and reinforced by preconceptions that helping the environment must hurt the economy
• There is increasing concern that the costs and impacts of failing to act could be large – but Australian economic modelling studies have not included the cost of failing to respond
• We need to resolve this tension
Economic modelling• Widespread misinterpretation of results• Most studies had limited scope:
– Cost of failure to respond set to zero
– Limited energy efficiency potential and expensive renewables
– Blanket carbon price applied – no sector-specific transition strategies
– No targeted ‘recycling’ of revenue
• Inclusion of non-CO2 gases cuts response cost• More trading cuts costs• Smart policy cuts costs• Including lower cost energy efficiency options cuts
costs
Example of ‘Worst case’ greenhouse response economic impact from early modelling: a cumulative 2% reduction in GDP over 12 years – many still believe it is 2% each
year. More recent studies tend to show lower costs.

Why is the economic impact of massive carbon prices so small?
• Energy a fairly small cost to the economy• Revenue from carbon price flows back through economy
via tax reductions, government investment• ‘winners’ gain increased demand for their products and
services• ‘losers’ are high greenhouse intensity industries and
suppliers of high greenhouse impact product (assuming no adjustment support and high C price) – but they’re 15% or less of Australia’s economy

To conclude:
• Costs of greenhouse response have been overstated while benefits have been ignored or understated, particularly in 1990s economic modelling
• Smart response policy and creative programs can reduce costs and impacts, and create benefits
• Much stronger and more comprehensive action is needed – but it can deliver
• We know what to do, but we need political will, resources and an informed community
