Developing CBDR-RC indices for fair allocation of emission reduction responsibilities and capabilities across countries

ARİ, Izzet
Sarı, Ramazan
The aim of this paper is to develop two indices for quantifying common but differentiated responsibilities (CBDR) and respective capabilities (RC) of countries in mitigating climate change. These composite indices can help facilitate fair allocation of GHG emission reduction responsibilities across countries. Indices are formulated by taking into account the economic, environmental, social, and technical indicators of a given country. These indicators are usually highly correlated. An index using these indicators must take this high correlation into account, otherwise it will either over or underestimate the responsibility and the capability of a country. This study takes the correlation between the indicators into account in developing the CBDR and RC indices via the principal components method. However, the novelty of this study arises from measuring and using economic, social, technical, and environmental indicators together in creating the composite indices. The CBDR and RC are constructed for 50 countries that are responsible for at least 81% of global GHG emissions, including OECD countries and emerging economies. The Cluster Analyses are employed to classify the countries according to their CBDR and RC scores. The results suggest revision of current responsibility and capability classifications of the UNFCCC.


A New approach for the classification of country parties in the UNFCCC

The objective of this study is to create countries’ composite indices for common but differentiated responsibilities and respective capabilities in order to determine fair allocation of GHG emission mitigation responsibilities between countries. All indices have been formulated by considering a country’s economic, environment, social, and technical indicators. These indicators, however, are normally correlated, and their correlation may overestimate each country’s responsibilities and capabilities; if the c...
Indicator-based evaluation of inter-linkages between different sustainable development objectives (INDI-LINK)
Kalaycıoğlu, Hediye Sibel(2006-11-31)
The INDI-LINK project has three main objectives: (1) further improvement of sustainable development indicators (SDI), (2) assessment of interlinkages between the different priorities of the EU SDS and (3) deriving conclusions for future SD policy making. To achieve these objectives, INDI-LINK will develop new concepts and methods and improve data for the calculation of selected 'best-needed' and proxy indicators; test different methods for extending indicator time series through forecasting; review emer...
National patterns of research output and priorities in renewable energy
Uzun, A (2002-01-01)
This paper attempts to compare the research Output and priorities of 25 major Countries in renewable energy research. The main objective is to assess the research priorities of the major countries in frontier areas subjects of renewable energy using some bibliometric measures based on renewable energy literature. Subjects of high activity and Subjects of low activity are identified for two time periods ( 1996-1997 and 1998 1999). Our findings, show that the output of publications including articles. reviews...
Assessment of responsible sectors having considerable pollution load in Yesilirmak river basin, Turkey
Erdem, Elif; Yetiş, Ülkü; Department of Environmental Engineering (2018)
The Water Framework Directive(WFD) of the European Union requires achieving good quantitative and qualitative status for all water bodies within its territory. For achieving good chemical and ecological status, the Member States were expected to comply with the Environmental Quality Standards(EQSs) for 45 dangerous substances identified as "priority" and river basin “specific pollutants” requiring identification. This study aims to identify the potential point pollution sources of the river basin specific p...
Common agricultural policy regionalised impact - the rural development dimension (CAPRI-RD)
Öcal, Nadir(2013-4-30)
The Common Agricultural Policy Regionalised Impact – the Rural Development Dimension (CAPRI-RD) aims to develop and apply an operational, Pan-European tool including all Candidate and Potential Candidate countries to analyse the regional impacts of all policy measures under CAP Pillar I and II across a wide range of economic, social and environmental indicators, aligned with the CMEF. CAPRI-RD’s core contains consistently linked economic models at the NUTS 2 level, the CAPRI model for agriculture, and a new...
