The Future of the Clean Development Mechanism. Note on the report “A Call to Action” of the High-Level Panel on CDM Policy Dialogue. CEPS Special Report No. 71, 20 November 2012

The clean development mechanism (CDM) has been through a long and complex growing process since it was approved as part of the Kyoto Protocol. It was designed within the framework of the UNFCCC and the Kyoto Protocol, and reflected the political and economic realities of that time. To ensure its continued effectiveness in contributing to future global climate action and to reflect on how best to position the CDM to respond to future challenges, a high-level panel (HLP) was formed at the Durban climate change conference in 2011. Following extensive consultations, the panel published its report in September 2012. Through this Special Report, the CEPS Carbon Market Forum offers its reflections on findings and recommendations of the HLP, as well as, by extension, its own views on the future of the CDM. In the context of the latter, it explores the following questions: Is there a need for an instrument such as the CDM in the future? What ‘demand’ can it fill? In the roles identified under the first question, what can be done to adapt it and also continue to increase its efficacy?

Analysis of void volumes in proteins and application to stability of the p53 tumour suppressor protein

We have developed a new method for the analysis of voids in proteins (defined as empty cavities not accessible to solvent). This method combines analysis of individual discrete voids with analysis of packing quality. While these are different aspects of the same effect, they have traditionally been analysed using different approaches. The method has been applied to the calculation of total void volume and maximum void size in a non-redundant set of protein domains and has been used to examine correlations between thermal stability and void size. The tumour-suppressor protein p53 has then been compared with the non-redundant data set to determine whether its low thermal stability results from poor packing. We found that p53 has average packing, but the detrimental effects of some previously unexplained mutations to p53 observed in cancer can be explained by the creation of unusually large voids.

The climate response to CO2 of the Hadley Centre coupled AOGCM with and without flux adjustment

Coupled atmosphere‐ocean general circulation models have a tendency to drift away from a realistic climatology. The modelled climate response to an increase of CO2 concentration may be incorrect if the simulation of the current climate has significant errors, so in many models, including ours, the drift is counteracted by applying prescribed fluxes of heat and fresh water at the ocean‐atmosphere interface in addition to the calculated surface exchanges. Since the additional fluxes do not have a physical basis, the use of this technique of “flux adjustment” itself introduces some uncertainty in the simulated response to increased CO2. We find that the global‐average temperature response of our model to CO2 increasing at 1% per year is about 30% less without flux adjustment than with flux adjustment. The geographical patterns of the response are similar, indicating that flux adjustment is not causing any gross distortion. The reduced size of the response is due to more effective vertical transport of heat into the ocean, and a somewhat smaller climate sensitivity. Although the response in both cases lies within the generally accepted range for the climate sensitivity, systematic uncertainties of this size are clearly undesirable, and the best strategy for future development is to improve the climate model in order to reduce the need for flux adjustment.

Small business legislation in Australia: does it provide a solution to part of the UK lease reform debate?

This paper addresses the commercial leases policy issue of how to deal with small business tenants. The UK has adopted a voluntary solution to commercial lease reform by using Codes of Practice which is in contrast to the legislative approach adopted by Australia to attempt to solve its perceived problems with small business retail tenancies. The major aim of the research was to examine the perceptions of the effectiveness of the legislation in Australia and discuss any implications for the UK policy debate but the results of the research also raise questions for the Australian regime. The research used a combination of literature and legislation review and a semi structured interview survey to investigate the policy aims and objectives of Australian Federal and State Governments, identify the nature and scope of the Australian legislation and examine perceptions of effectiveness of the legislation in informing small business tenants. The situation is complicated in Australia due to leases being a State rather than Federal responsibility therefore the main fieldwork was carried out in one case study State, Victoria. The paper concludes that some aspects of the Australian system can inform the UK policy debate including mandatory information provision at the commencement of negotiations and the use of lease registrars/commissioners. However, there are a number of issues that the Australian legislation does not appear to have successfully addressed including the difficulties of legislating across partial segments of the commercial property market and the collection of data for enforcement purposes.
