Options for Change in the Australian Energy Profile

Abstract

Climate change is occurring largely as a result of increasing CO 2 emissions whose reduction requires greater efficiency in energy production and use and diversification of energy sources away from fossil fuels. These issues were central to the United Nation climate change discussions in Durban in December 2011 where it was agreed that a legally binding agreement to decrease greenhouse gas emissions should be reached by 2015. In the interim, nations were left with the agreement reached at the analogous 2009 Copenhagen and 2010 Cancun meetings that atmospheric CO 2 levels should be constrained to limit the global temperature rise to 2°C. However, the route to this objective was largely left to individual nations to decide. It is within this context that options for reduction in the 95 % fossil fuel dependency and high CO 2 emissivity of the Australian energy profile using current technologies are considered. It is shown that electricity generation in particular presents significant options for changing to a less fossil fuel dependent and CO 2 emissive energy profile.

Windfall gains or eco-innovation? ‘Green’ evolution in the Swedish innovation system

“…"Eco-innovation" has been defined by Arundel and Kemp (2009: 5) In particular, in this paper, we will look more closely the reduction of CO 2 aspect of ecoinnovation, and the factors affecting this aspect of greener innovation (Figge and Hahn 2004;Arundel and Kemp 2009). This research therefore touches upon a number of issues, such as energy transitions and innovation dynamics (Safarzynska 2013;Schmidt et al 2012;Ghisetti and Quatraro 2013), the "Porter hypothesis" that environmental standards can trigger innovation offsets (Porter and van der Linde 1995), functions of innovation systems (Hekkert et al 2007;Tukker 2008), CO 2 emissions in Swedish manufacturing industries (Pardo Martínez and Silveira 2013;Bergquist and Söderholm 2011;Guziana 2011), country case comparison in the shift from fossil to non-fossil fuel (Lincoln 2012;Wang et al 2012;Armstrong and Blundell 2007;Costantini 2013;Costantini et al 2012), responses to the global climate change (Witthaus 2012), and more generally, models of evolutionary environmental economics (Faber and Frenken 2009;Bergh 2007). Since education indicators are used in the statistical analysis, our results should also be interesting for those who investigate aspects of knowledge versus formal education in relation to innovation (Jensen et al 2007;Colombelli et al 2013).…”

The emission trading system, risk management committee and voluntary corporate response to climate change – a CDP study

“…states, public, investors and lobbyists) and they have put climate change on corporate agendas and expect firms to disclose relevant GHG information (Depoers et al, 2016). Many emission reduction strategies have been recently implemented worldwide that aim to reduce GHG emissions (Lincoln, 2012). The greenhouse effect is caused primarily by the burning of wood and fossil fuels (coal, natural gas, oil and peat) which release enormous amounts of carbon dioxide (CO 2 ) into the atmosphere (Oskamp, 2007).…”
