Climate Change and Its Socioeconomic Importance
Climate change has played an increasingly key role in recent years and is now one of the leading
political priorities worldwide. This article illustrates the scope of the problem, its causes and its
impacts, along with the possible solutions that are being considered on the international stage. The
existing information regarding these topics is summarised, together with the associated costs and the
scale of the effort required to tackle climate change. The article explains why climate change can be
seen as a market failure, the importance of public policies to correct this problem and its impact on
international trade. The last section considers the international debate taking place in the United
Nations Conferences and the Kyoto Protocol as well as what is expected with respect to the future post-
Kyoto negotiations.

1. Introduction: Raising Concerns
Nowadays, nobody doubts that climate change is one of the greatest challenges facing humanity
or that it is man-made in origin. Yet, climate change also has three characteristics that make it particularly
important and unique:
• First, and even though there has been considerable scientific progress regarding knowledge on
climate change, there continues to be great uncertainty regarding the future impacts on a
planetary scale and, of course, regarding the extent that each eco-system and each region will be
affected. However, it is clear that the consequences will be of great magnitude.
• The second characteristic is to do with the fact that the impacts, even though they have already
begun to be noted, are going to have very long-term consequences in 2050, 2100 and beyond.
• And thirdly, that although it is a global problem, the responsibility of some countries and others is
not the same, in fact far from it. Therefore, the distribution of the burden to deal with it cannot be
the same.
These characteristics mean that climate change is an area where it is extremely complex to
transmit the increasing concern in the world of science regarding how this problem is progressing to
society, to politicians and to other stakeholders.
The concern about climate change emerged for the first time on an international scale during the
World Climate Conference held in Geneva in 1979. Since then, some milestones that are examples of the
awakening of the deep concern about this phenomenon have included:
• the 1985 United Nations Conference on the Greenhouse Gas Emissions in Austria,
• the setting up of the Intergovernmental Panel on Climate Change (IPCC) as the
Intergovernmental Working Group on Climate Change in 1988, and
• the creation of the United Nations Framework Convention on Climate Change (UNFCCC) in
1992 during the Rio de Janeiro summit (and its implementation in 1994).
There have been other milestones, such as the signing of the Kyoto Protocol (KP) or the different
Conferences of the Parties (CoP) and Conferences of the Protocol Parties, as the politicians around the
world have discovered the scope and seriousness of the problem.
The successive IPCC reports (1990, 1995, 2001 and 2007) analysed the existing scientific
knowledge on topics such as potential impacts, possibilities for adaptation and vulnerability, or the
opportunities to reduce Greenhouse Gas (GHG) emissions. These reports have decisively contributed to
generating current world consensus regarding the seriousness of the situation and the burning need to act
in a decisive manner. Other reports, such as the well-known Stern report (2006), have also significantly
helped to put climate change on the list of the top policy priorities.

2. Climate Change and Scientific Knowledge
2.1 Evolution of climate, impact and causes
The IPCC has clearly stated that there is sufficient scientific evidence regarding the unequivocal
warming of the climate on all continents, particularly in the upper northern areas and in the majority of
seas (IPCC, 2007a).
This change has been more intense during the last century and continues to speed up. The rise in
sea levels, the disappearance of ice, changes in precipitation or even increased tropical cyclone activity
seem to endorse this fact. Specifically, it can be said that “the average Northern Hemispheres
temperatures during the second half of the 20th century were higher than during any other 50-year period
in the last 500 years. It is possibly the highest in at least the past 1,300 years.” (IPCC, 2007a).
The warming is affecting nearly all marine and terrestrial eco-systems, beginning with the Arctic
and Antarctic eco-systems and even including tropical marine environments. Regional climate changes
already affect (or will affect) nearly all human and natural environments.
Other impacts analysed include the changes in the availability of fresh water, droughts or floods,
the loss of any type of species and eco-systems, the dramatic changes in agricultural productivity,
increased storm activities and sea flooding, the rise in the incidences of tropical diseases, malnutrition and
infections, the change in the disease vectors or the changes in mortality or morbidity. The majority of
these are negative, large-scale impacts that will affect most of the planet. (See Table 1).
Some of the scenarios developed by scientists forecast impacts that may even be catastrophic. The
greatest impact will be on the poorest and more vulnerable regions and may lead to increases in the
migratory processes and social instability. (IPCC, op. cit.).
The IPCC also points out that much of this rise in global temperature is highly likely to be
explained by the observed increase in GHG concentrations as the result of human activities, mainly due to
the use of fossil fuels and the changes in land use. Increases in these emissions began to be noted from the
pre-industrial era onwards, but shot up by 70% between 1970 and 2004. These gases, along with aerosols,
changes in land coverage and solar radiation are responsible for changes in the balance of the climatic
system. (IPPC 2007a).
The accelerated increase in the emissions has meant that concentration levels that were around
280 parts per million (ppm) at the start of the century had risen to 379 for 2005, which is much higher
than the natural levels over the last 650,000 years. It is estimated that this trend for increased GHG
concentrations may lead to a rise in temperatures of between 1.1 and 6.4 degree Celsius by 2100 (IPCC
2007b).
3
Table 1: Examples of impacts associated to Climate Change
Authors such as Weizmann (2008) note the worrying fact that some of the IPCC scenarios also
include rises in GHG concentrations that would mean temperature increases of up to 4.5ºC with a
probability of 17%. Or even 8 ºC with a probability of 2%. These scenarios, even though less likely than
more favourable ones, are rather more alarming and would mean that many regions of the planet would
become inhabitable.
With global GHG emission rates on the scale that has recently been observed, changes in the
world climatic system during the 21st century may be much greater than those that occurred in the 20th
century. And that is cause for great concern.

2008). The latter likewise conditions the policies aimed at technology and establishing prices for CO2e
(Stern, 2008)
As far as global emissions are concerned, this means a dramatic change in the trend, with
maximum world emissions being reached by 2020. They would then be reduced by between 1% and 2.5%
per year from then onwards (Stern, 2006).
“As a rule of thumb one can think of emissions declining by 50 percent relative to 2000 levels by
2050 for the planet to be on this stabilization path” (Markandya 2009).
Taking into account fairness in sharing the burden among rich and poor countries, these targets
suggest that the developed countries must reduce their global emissions by a percentage of around 60-
90% by 2050. These reduction targets are truly important and illustrate the size of the challenge to be
undertaken.

Table 2: Examples of adaptation policies
The first (adaptation) includes all those aimed at recovering the affected ecosystems, redesigning
energy, transport or water supply infrastructures or adapting agricultural crops to the new conditions (see
Table 2). The second (mitigation) include all those measures to save and ensure efficient use of energy
resources, promote renewable energies and sustainable transport or the use of market instruments as
incentives to decarbonise the economy (see Table 3).
6
Table 3: Examples of mitigation policies
The Kyoto Protocol and the UNFCCC negotiation process are the political setting for all these
policy measures on the international stage. Both seek to regulate policies on a global scale. Practically all
national governments, many regional and some local ones directly or indirectly participate in this process.
Section 5 of this paper considers both the KP and the context of the UNFCCC:
7
The scientific community has established the atmosphere load threshold scenarios, along with the
ensuing reductions in emissions required for each case. Many experts consider that these reductions can
be viably achieved without imposing an excessive economic cost on the economies of the world.
However, it is true that there are huge differences with respect to the effort required by different sectors of
activity and, above all, by different countries and regions.
Markandya (2009) recalls that the aforementioned Stern report, after analysing different studies,
concludes that a cost of around 3%-5% of the annual gross domestic product in 2050 has to be considered
to achieve the 550 ppm target. Consequently, based on an annual increase of the annual GDP of around
2.8% until 2050, he estimates that this target will cost around 7,800 billion US dollars. In other words, in
accordance with the World Bank economic data and UN population forecasts, 846 dollars per capita in
2050 on an average income per capita of 24,165 dollars.
The aforementioned author refers to other estimates such as those performed by Golub et at
(2006) that quantify a relatively small cost, which is under 0.5% of the gross domestic product of the
United States of America in some cases when calculating the environmental benefits arising from this
policy.

The IPCC (2007a) establishes that the mitigation cost of stabilisation of around 710 and 455 ppm
is between 1% and 5.5% of the world GDP for 2050. The comparison of the different studies existing in
the literature to estimate the mitigation costs suggests that the majority estimate ranges of between 0.5%
and 2% of the world GDP (See Figure 1).
With regards to the costs arising from failing to implement climate change policies and
continuing along the present path, the Stern report suggests that they could reach between 5% and 20% of
the world GDP once the losses that have no market value (such as the loss of biodiversity or damage to
the ecosystems) have been included. Other studies are around the lower limit of the Stern report.
The main reason for this difference in the estimates is to do with the difference in the concepts
assessed, but above all, with the use of different discount rates. Even though discounting is standard
practice in economics to compare current costs with future profits - in other words, a lower value is
allocated to the costs or future profits -, it can be argued that lower discount rates near to zero should be
applied in the case of climate change, as was the case in the Stern report. This is justified by the length of
the horizons analysed and by the irreversibility of the impact. Other studies such as Yohe et al (2008)
have been criticized for undervaluing their estimates by applying discount rates near to 4 or 5%. These
are excessively high for this issue.
As far as regional impacts are concerned, some more specific studies exist that seek to measure
local impacts. This task is not easy and the reliability of the data being used must still be significantly
improved. The regionalisation of the impact is one of the areas where the IPCC insists that significant
emphasis must be placed over the coming years.
Specifically, and by way of an example, there are different studies for the Basque Country where
it is estimated that, in the case of a hypothetical flood in Bilbao, the costs may increase by 56.4% as the
result of climate change, with the figure of 158 million euros a year being cited (IHOBE, 2007). Other
case studies have been carried out for the River Urola basin where the increase of the expected annual
damage is similar (Oses, 2009). In any case, and despite the existence of these studies, the need to go
further into this type of more regionalised analysis of the impact continues to be pressing.
With regards the Willingness to Pay (WTP) of the society for the implementation of plans to
combat climate change, a recent study (Longo et al. 2008) shows that the aggregate WTP to implement
the Basque Plan to Combat Climate Change (PVLCC) is estimated to be 400.6 million euros, while its
costs are calculated to be 79.5 million euro.
9
Yet, the reductions that can be undertaken over the coming 20 or 30 years will also be decisive in
terms of the likelihood of achieving greater reductions in the future.
Table 4 shows some stabilization horizons and estimates the emissions reductions that are
required to achieve these objectives. The most ambitious stabilization scenario requires the emission
levels in 2030 to be similar to those in 2000 and reductions of up to 80% are needed by 2050. Other less
ambitious scenarios reflect easier targets.
2020 -- -- --
2040 -- -- --
In any case, the challenge facing humanity and the importance of the decisions taken over the
coming years require a clearly long-term vocation. The policy to fight climate change must allow the
portfolio of options to be kept open so that they can be adjusted to deal with the changes that may arise in
the future. Other sections of this article will look into these concepts in greater detail.
10
3. Socio-Economic Importance
3.1 Market failure
Stern himself (2006) defines climate change as “the greatest market failure ever seen” and a great
challenge facing humanity.
It is long ago that economic literature clearly defined the determining factors for the market to
allocate the resources in the most efficient way possible. This situation has become known as perfect
competition and occurs when there are many players buying and selling, when the information is perfect
(real, complete and free), there are no barriers to enter or exit the market and the product is homogeneous.
When any of these determining factors are not met, the market fails to provide these goods or
services, either by generating under-provision or over-provision of said goods and services. This is what
economists refer to as "market failure".
Public assets are a clear example of this. They are defined as those where there is no rivalry in
their consumption and they are not exclusive. In other words, the fact that one individual uses them does
not prevent another one from doing so or being able to do so in the future. In terms of the presence of
public goods, cases of under-provision can occur with the ensuing need to intervene on the market to
correct those "failures" (Samuelson, 1954).
As well as being able to model itself as a global public goods for which no market exists, climate
change is the result of a negative externality (Stern, 2006) - greenhouse gas emission – where the parties
responsible do not consider this as a cost within their sphere of responsibility. Negative externalities are
characterised for generating a loss or damage to a third party who is not the person in charge of the
activity.
Climate change stands out from other negative externalities due to some different specific
characteristics (Stern, 2006, 2008):
-The global sphere of its causes and of its consequences:
-The impact is long-term, persistent in time and dominated by the relationship between flow and
stock or GHG concentration.
-There is a high component of uncertainty and risk.
-There is a serious risk of important and irreversible changes with economic effects that are not
marginal.
These characteristics determine the type of economic analysis that must be structured for climate
change, but particularly in relation to the policy instruments that must be used.
In this context, the traditional theory of externalities or the use of the Cost Benefit Analysis are
highly limited for tackling such a complex problem. It is fundamental that the risk variable and the
possibility of such severe impacts are effectively incorporated.
11
The existence of a high degree of uncertainty, together with the possibility that extreme events
may occur, suggests that employing the expected values used in the traditional analysis is not appropriate
in this case. Neither does using the CBA seem to be exempt from criticism (Weitzman, 2007) 2.
The long-term nature of the problem suggests, as has already been established in this article, that
there are significant reasons for not using standard discount rates as they are deemed to be excessively
high. In other words, an excessively low present value for the damages (and benefits) that may occur in
the future is imposed. The use of these rates cannot be justified from the perspective of inter-generational
ethics. The discussion is open regarding what the appropriate discount rates must be.
While some policy instruments, such as the emissions trading scheme or the CO2 taxes, are based
on the well-known (and very valid) Coase (1960) and Pigou (1920) theories to correct externalities,
economic analysis needs to effectively settle a high number of issues in this field. Particularly as regards
the incorporation of the variables of uncertainty, risk and the very long-term nature of climate change.
Answering these questions is no trivial matter.
Nonetheless, the fact that there are these issues to be settled does not invalidate the need for
actions to be urgently proposed and the validity of the approaches that require establishing a price for
CO2 that force its cost to be internalised.
2
The probability of events occurring whose consequences may be catastrophic is what is known as “Fat Tail” of the
distribution of probability. One criticism of the author about the Stern report regards the importance of assessing the
possibility of catastrophic effects occurring. This possibility invalidates the probabilities approach traditionally used
in risk analysis.
12
Other important issues that must be highlighted are to do with how to compare concepts as
complex as the “quality of life" or "welfare", or the difficulty of comparing these concepts between
countries and people with very different ways of understanding life. This all makes combating climate
change a field where economic analysis techniques must be adapted and substantially improved.
The long-term, uncertainty and the risk also have implications that directly affection ethical issues
as we have already mentioned (discount rates, for example), but also other questions relating to how to
apply the precautionary or proportionality principle have to be considered.
Many of these issues were discussed in the Stern report in relative detail. The report itself
received a wide range of criticism 3 –both positive and negative— from very different areas of the
economy, even though nobody questioned the political importance of its conclusions that have triggered
the debate in different fields of economic analysis.

that exports in developing countries seem to have increased with regard to imports. However, this type of
simple analysis also requires other more complex questions to be answered. For example, the import-
export ratios in USA-Europe relations increases for the USA, while the ratio decreases for Europe, which
is not in line with the increasingly more ambitious standards that are being laid down in Europe.
However, the USA ratio with respect to China or other Asian countries seems to fall in those countries
and it therefore does seem that relocations of production processes in those countries is happening. No
clear trend seems to exist for other developing countries.
Therefore, there seems to be some evidence with respect to these leakages being real, although
they are significantly less than what is usually feared in any event.
This is a highly interesting debate as it may back positions that suggest the use of trade barriers
for those countries that are reluctant to implement measures to combat climatic change.
International trade rules generically forbid this type of measures even though the World Trade
Organisations considers the jury to be still out. Some similar precedents seem to suggest that this type of
measures may be deemed legal and also relatively effective to boost climate change policies.
14
of possibilities to refine the policy in the future. Perhaps in the next 50 or 100 years. There is an
opportunity cost of the policies not implemented that must be taken into account and internalised in the
decision-making process. In other words, to opt decidedly for nuclear energy today, for example, could
mean moving away from other investment goals in renewable energy if both policy objectives are not
duly weighted, while totally ruling out this source of energy may considerably limit the real possibilities
to move towards a decarbonised economy. Opting for providing transport infrastructures may be at odds
with the appropriate management of the demand for mobility, a key element in a sustainable mobility
policy and often overlooked. Keeping a balance portfolio of policy options is one of the greatest public
management challenges in any field of action, and this is particularly important when it comes to
combating climate change.
15
4.3 The role of technology and R&D&I
The scientific community has regularly warned that technology and innovation have a
fundamental role in achieving the ambitious emission mitigation targets that are being negotiated on a
global scale. Specifically, if the technological improvements and the potential future improvements are
not considered, the maximum ceiling for emissions reduction in the field of energy may be near to 30%,
while reduction of up to 60% may be achieved with appropriate technological development in developed
countries, such as the United Kingdom or Germany. In the case of developing countries, technology
transfer is a determining factor to tackle mitigation policies with certain guarantees.
16
Authors, such as Pacala and Socolow (2004), have established the necessary emission reduction
in order to work towards the goal to reduce the emissions dramatically over the coming 50 years. Figure 2
summarises the main conclusions of this study that establishes that with the existing technologies,
emissions may be reduced by 7 GtC/year (equivalent to ~3.67 Gt CO2). A truly significant number. They
establish the burden that each of the following measures should share.
• energy efficiency (efficient vehicles, reduction in use of vehicles, efficient building, coal
plant efficiency)
• decarbonising energy (replacing coal by gas, CO2 capture, replacing coal by nuclear
energy, replacing coal by wind energy, replacing coal by solar energy)
• decarbonising fuels (CO2 capture in H2 plants, biofuels, hydrogen for hybrid vehicles,
etc.)
• and agriculture and forestry resources (reduction of deforestation, reforestation, new
groups, etc.).
What seems to be clear in the literature is that the role of technology will be fundamental in order
to work towards decarbonising the economy over the coming 30-50 years, both with regard to the role of
technological transfer to developing countries and with respect to technological research and
development.
17
Eliminating the obstacles to technology transfer by means of reducing custom tariffs, technical
standards, bureaucratic processes and other obstacles is fundamental to achieve GHG emission reductions
in developing countries. Working on technological development in the different emission mitigation
fields will decisively help to reduce the associated costs. Figure 3 provides an example of a marginal
abatement cost curve. It shows how the cost of reducing an additional ton of CO2 will dramatically
decrease as technological development in each field progresses. Those fields where less development has
taken place have greater potential to reduce marginal costs.
Technology and R&D&I thus become core points in any policy to combat climate change and we
will therefore move on to considering the Kyoto Protocol in the next section.
18
5.2 CoP 15 Copenhagen 2009
Although no major decisions were adopted at the last summit (CoP 14) nor was a clear political
leadership set up to take on the ambitious mitigation and adaptation targets recommended by the IPCC, it
was not a significant step backwards in international negotiations (Santarius et al. 2009). The summit
was a milestone without any particular importance along the path to the long-awaited Copenhagen
summit.
For this coming summit (Copenhagen Cop 15), developed countries are seeking clear
commitment from developing countries to achieve significant emissions reductions, particularly from
rapidly growing countries (China, Brazil and India), while the latter are expecting important commitments
from the developed countries in terms of reducing emissions and providing real technological, political
and economic support for the targets of the developing countries. The lack of leadership that Europe has
shown over the last year and the historical absence of the USA during the Bush's term of office in the
group of driving forces behind the international agreements have hindered the possibilities of breaking
this vicious circle. The undertakings of the new president of the USA, Barack Obama, and the triumph
that the vision that climate change is not a zero-sum game but rather that it is fundamental to develop geo-
political strategies in cooperation leaves some room for hope for the Copenhagen summit (Santarius op
cit).
In the words of Yvo de Boer7, the CoP15 will be successful if it answers the following four
questions: What is the emission reduction undertaking that the industrialised countries are willing to
reach? What are the targets that developing countries such as China and India are willing to assume?
How will the aid be funded that developing countries need to achieve ambitious reduction targets? And
how are all these economic resources going to be managed? The first step should come from the
developed countries in the form of mitigation targets in accordance with the IPCC recommendations and
the clear commitment of technological and financial support for the developing countries.
An optimistic view of the summit suggests that it will enable these questions to be positively
resolved for the new agreement that succeeds the Kyoto Protocol to be valid. The global crisis scenario
will undoubtedly be another obstacle to get over, in that it will hinder the investments required to deal
with this huge global challenge. Many of the investments in energy, transport and other infrastructures
that are decided today will condition the emissions scenarios over the coming 20 or 30 years.
6. Conclusions
Very few people doubt, nowadays, that climate change is already a scientific reality that
represents a huge challenge facing humanity. A challenge that requires our full attention and skills to
avoid impacts that could be far reaching. Impacts on the health of people, the environment, the
inhabitability of some geographical zones or the validity of the transport or energy infrastructures. Some
of the proposed scenarios involve catastrophic impacts.
The reduction of GHG emissions as a formula to reduce the gas concentration levels in the
atmosphere (and thus climate change) is one of the approaches that must underpin the policies. But even
though these could be highly effective, some changes and impacts are already occurring and will continue
7

19
to take place. Therefore adaptation measures are also vital. Mitigation is in line with the undertaking to
the planet while adaptation to the undertaking with our most immediate environment and its inhabitants.
Economic analysis is not exempt from difficulties or criticism. Selecting the appropriate discount
rates illustrates the difficulty to include the long term (or the very long term) to the economic analysis.
The use of standard discount rates is not acceptable from the perspective of inter-generational equity. The
uncertainty that surrounds the impacts that must be assessed advises against the use of the expected values
approach.
Public intervention is necessary to correct this market failure and it is also not exempt from
difficulties. Such a policy must combine many areas of intervention like environment, energy or transport,
and requires efforts to be coordinated at all levels of the public administration.
The ethical considerations must be incorporated in the analysis to guarantee fair treatment for
future generations, but also for developing countries whose contribution to global emissions has
historically been far lower than that of developed countries. Transfer technology towards these countries
and the role of innovation and technological development must not be avoided.
Climate change policies may lead to changes in the flows of international trade as a consequence
of the distortions that are generated from the fact that different policies are implemented in different
countries. This point must also be taken into account.
The Kyoto Protocol has marked the start of a global negotiating process that must end in highly
significant reductions of GHG emissions, but the challenge is still greater for 2020, 2050 or 2100. Today's
decisions will condition the future and the possibilities of achieving greater progress over the coming
decades and therefore the design and execution of the policies is fundamental. The Copenhagen summit in
December 2009 must establish the Post-Kyoto regime and the path from 2012 onwards. The new US
policy, the credibility of developed countries regarding the mitigation targets, but also with respect to the
effort to ensure that the developing countries assume their part of the process (mainly financial and
technological) will determine the success or failure of the long-term climate policy.
