A survey of carbon exchanges

Date 29/10/2008

Eric Bettelheim and Gregory Janetos[1]

The growth in carbon exchange trading activity has mirrored that of the carbon market as a whole. Five years ago, only the Chicago Climate Exchange was actually trading and it was, and remains, a wholly voluntary market. Today there are some 19 carbon exchange initiatives, 11 of which are already trading. They are located in every major geographic region and vary from simple matching of buyer and seller (Australian Climate Exchange) to auction markets (Asia Carbon Exchange) and from those limited to European Union Allowances (EUAs) and Kyoto Protocol Certified Emission Reductions (CERs) like the ECX, to those which will soon offer the full panoply of products from voluntary to mandatory and offer the full range of exchange services: trading, clearing and settlement.

The volume of transactions varies widely-driven, as would be expected, by underlying market activity. By far the largest volume is in EUAs and CERs, particularly CERs destined for the European Union Emissions Trading Scheme (EU ETS). The EU ETS, the world’s largest compliance market, represents some two-thirds of carbon market activity. Its dominance is reflected both in terms of volume and volatility. EU demand is quickly reflected in prices for EU-compliant exchange listed products. The structural flaws in the EU ETS are also quickly reflected in exchange traded prices. The revelation that the European Commission had issued too many emissions permits in Phase One of the EU ETS saw the collapse of EUA prices on the exchanges listing them. The recent announcement by the European Commission of its intention to curtail use of CERs in Phase Three (beginning 2012) had an almost immediate depressive effect on both prices and exchange activity. These are indications of healthy market functioning, even if also a manifestation of poor market regulation.

The regulatory behaviour of the Clean Development Mechanism (CDM) as ‘issuer’ of CERs similarly affects market expectations and behaviour. Recent analyses of the actual credit delivery of the projects it has approved, of the long delays in obtaining project approval, of the high costs of doing so and apparently arbitrary decision making, have similarly shown negative effects not only on exchange prices for CERs but also on the share prices of market participants, particularly CER aggregators, and on the shares of listed exchanges trading CERs. The exchange traded prices for CERs have also reacted to perceived differences in the quality of the projects underlying some CERs. The markets quickly distinguished between credits generated by destruction of the potent greenhouse gas trifluoromethane (HFC23) and those generated by energy-related projects, marking the HFC-based CERs down in price. This too is a healthy manifestation of the market function of differentiating prices based on perceived differences in quality of the underlying products.

Hedging activity, particularly between CERs and EUAs, has also emerged to some degree. The carbon market is still overwhelmingly an over-the-counter marketplace and will probably continue to be so for some time. This is a function both of its early stage of development and of the unstable nature of its regulatory regimes.

The Achilles heel of the markets is the uncertainty created by repeated political and regulatory interference. Both of today’s largest systems, Kyoto and the EU ETS, institutionalise this interference by carving up compliance into 5-year periods. This is clearly at odds with the need for long-term investment, measured in decades, to deal with global climate change. Markets cannot function efficiently either in accumulating and allocating capital, or in pricing and distributing risk, in such an environment. Until the regulatory framework becomes much more stable, through the adoption of stable long term emission abatement goals, and the regulatory environment becomes much more professionalized, price volatility on exchanges will remain too high and volumes are likely to remain too low for effective hedging of large scale investments. The role of large scale financial institutions, as both structurers of products and distributors of risk, is likely to remain dominant until these structural issues are addressed.

The rapidly growing voluntary market, now almost entirely OTC outside the United States and significantly so there too, is showing signs of acting as a market leader in product design and as an indicator of future demand. For example, the dominance of forest project credits in the voluntary market is in striking contrast to their virtual absence in the regulated sector. Recent efforts of current regulators, such as the UK’s Department for Environment, Food and Rural Affairs (DEFRA), have failed to address this reality. The continued delegation of carbon market regulation to environment ministries, which have thus far dominated the political and regulatory debate, needs to be overcome if what are, after all, financial markets and products are to prosper. Such ministries and bodies – DG Environment in the EU and the Executive Board of the CDM – have no experience and no expertise either in capital investment or in financial market regulation. The effect of this on exchange and market development as whole has been, and continues to be, retrograde.

The carbon exchanges, like the carbon market as a whole, are clearly still at an early stage of development and reflect the remaining political uncertainties in the climate change debate. Nevertheless, they are already beginning to function as centres of price discovery and dissemination and will, inevitably, grow in size and complexity as those uncertainties are reduced. The key question as to their relative success, liquidity, will no doubt remain unanswered for some time. As can be seen from the survey below, there is already healthy competition between exchanges to become key centers of liquidity. There is, however, a competitive advantage for those exchanges in countries where the over-riding legislation sets clear long-term emissions reduction goals and those with stable and professional regulatory regimes, such as those in the UK, Australia, New Zealand and the United States.

The other, the Canadian Climate Exchange, owned by Intercontinental Exchange (ICE), was created in 2003 to explore and develop market-based solutions to climate change. It was the first such entity created by a regulated Canadian exchange.

    In December 2005, the Montreal Exchange and the Chicago Climate Exchange announced the formation of a joint venture creating the Montreal Climate Exchange to trade carbon futures contracts. In October 2007, The Montreal Exchange filed for regulatory approval of market rules to govern the trading of environmental products on the Montreal Climate Exchange.

    SOUTH AMERICA

    Brazil Mercantile and Futures Exchange (BM&F)
