Climate Change and its Complex Challenges

 

The time has never been better to tackle the immense and multidimensional challenge of climate change – that is the message of 2010World Development Report, the thirty-second in the series, titled, “Development and Climate Change”. Climate change is one of the most complex challenges of our young century. No country is immune. No country alone can take on the interconnected challenges posed by climate change, including controversial political decisions, daunting technological change and far-reaching global consequences.
 
 Human activity is warming the planet. Such warming has never been experienced by mankind and the resulting physical impacts would severely limit development. Only through immediate and ambitious actions to curb greenhouse gas emissions may dangerous warming be avoided. Global climate models that estimate the effect of different future emission scenarios on Earth’s climate predict a range of possible global temperatures for this century. These estimates show that even the most aggressive mitigation efforts may lead to warming of 2ºC or more (a level already considered dangerous), and most models project that less mitigation would lead to warming of 3ºC or even up to 5ºC and beyond (though with less certainty around these higher amounts of warming).
 
Global cooperation at the scale needed to deal with climate change can happen only if it is based on a global agreement that addresses the needs and constraints of developing countries, only if it can separate where mitigation happens from who bears the burden of this effort, and only if it creates financial instruments to encourage and facilitate mitigation, even in countries that are rich in coal and poor in income or that have contributed little or nothing historically to climate change. Whether these countries seize the opportunity to embark on a more sustainable development path will be heavily influenced by the financial and technical support that higher-income countries can muster. Otherwise the transition costs could be prohibitive.
 
Global cooperation will require more than financial contributions, however. Behavioral economics and social psychology show that people tend to reject deals they perceive as unfair toward them, even if they stand to benefit. So the fact that it is in everyone’s interest to collaborate is no guarantee of success. There are real concerns among developing countries that a drive to integrate climate and development could shift responsibility for mitigation onto the developing world. Enshrining a principle of equity in a global deal would do much to dispel such concerns and generate trust. Another major concern of developing countries is technology access. Innovation in climate-related technologies remains concentrated in high-income countries, although developing countries are increasing their presence (China is seventh in overall renewable energy patents, and an Indian firm is now the leader in on-road electric cars). In addition, developing countries – at least the smaller or poorer ones – may need assistance to produce new technology or tailor it to their circumstances. This is particularly problematic for adaptation, where technologies can be very location specific.
 
International transfers of clean technologies have so far been modest. They have occurred in at best one-third of the projects funded through the Clean Development Mechanism (CDM), the main channel for financing investments in low-carbon technologies in developing countries. According to the 2010 World Development Report (page 23), the CDM has in many ways exceeded expectations, growing rapidly, stimulating learning, raising awareness of mitigation options, and building capacity. However, the CDM also has many limitations, including low development co-benefits, questionable additionality (because the CDM generates carbon credits for emission reductions relative to a baseline, the choice of baseline can always be questioned), weak governance, inefficient operation, limited scope (key sectors such as transport are not covered), and concerns about market continuity beyond 2012.For the effectiveness of climate actions it is also important to understand that CDM transactions do not reduce global carbon emissions beyond agreed commitments – they simply change where they occur (in developing rather than developed countries) and lower the cost of mitigation (thereby increasing efficiency).
 
The Adaptation Fund under the Kyoto Protocol employs a novel financing instrument in the form of a 2 percent tax on certified emission reductions (units of carbon offset generated by the CDM). This clearly raises finance that is additional to other sources, but this approach has several undesirable characteristics. The instrument is taxing a good (mitigation finance) rather than a bad (carbon emissions) and like any tax, there are inevitable inefficiencies (deadweight losses). Analysis of the CDM market suggests that most of the lost gains from trade as a result of the tax would fall on developing-country suppliers of carbon credits. Adaptation finance will also require an allocation mechanism that ideally would embrace the principles of transparency, efficiency, and equity-efficient approaches would direct finance to the most vulnerable countries and those with the greatest capacity to manage adaptation, while equity would require that particular weight be given to the poorest nations.
The current negotiations, culminated in Copenhagen in December 2009, have been making slow progress – inertia in the political sphere. For all the reasons which include – inertia in the climate system, inertia in infrastructure, inertia in socioeconomic systems – a better climate deal is urgently needed. However, it must be a smart deal, one that creates the incentives for efficient solutions, for flows of finance and the development of new technologies. Furthermore, it must be an equitable deal, one that meets the needs and aspirations of developing countries. Only this can create the right climate for development.
