Climate change – an integrated framework Source: IPCC 2001
Environmental issue, rising emissions Deeply economic issue – at heart of energy economy “Climate change presents a unique challenge for economics: it is the greatest and widest-ranging market failure ever seen” (Stern Review 2006) Climate change economics
History: minerals-energy complex • Complex comprising mining, minerals processing, the energy sector, and associated industries (Fine & Rustomjee 1996) • Coal • ¾ of TPES • > 90% of electricity • ‘cheap’ and inefficient • Particular challenge for mitgation … • … while increasing access to affordable eneryg services • Short-term: energy efficiency • Medium-term: change fuel mix
Future: low-carbon future • Redefine competitive advantage • from attracting energy-intensive sectors • to building a new advantage around climate-friendly technologies and systems
Towards climate policy • LTMS strategic option of ‘Use the Market’ • Polokwane resolution on climate change • Treasury work on environmental fiscal reform • Theme of ‘putting a price on carbon’ • Question is ‘how?’
Carbon and carbon markets • Markets are a means, not an end • May be efficient, but not good at equity • Carbon cycle is global – problem of common property management • How to manage • Multi-laterally – UNFCCC, but also other scales • Price vs quantity • Pure regulation – standards • Pure price – tax • Combination – cap-and-trade
Conceptual distinctions Economic instruments Regulatoryinstruments GHG emission standards Carbon tax Direct Cap and trade Fuel input tax Indirect Building standards Greenor white certificates
Some broad questions • What would the distributional implications of different economic instruments be? • What are the implications, including costs and benefits, of choosing to use an economic instrument for mitigation? • How could different instruments be combined • How responsive is the system (and its parts) to various economic instruments for mitigation? (elasticity) • What would a consistent and effective approach to energy-intensive sectors, in order to increase efficiency, encourage fuel switching and eventually diversify products • What are the key design elements that need to be considered to design the best instrument for mitigation in SA? • What supportive measures might be needed to implement a set of instruments? Implications of existing policy? What legal and institutional arrangements could we build on?
