Climate Change: The Good, The Bad, and the Ugly


As an environmental studies major, I am very interested in what is being done to stop climate change and more importantly what can be done. In this post, I will examine one NGO’s prosed solution. The most important first step in climate change mitigation is educating people on the facts and ensuring that everyone understands the necessity and urgency of the situation.

Lets take a look at the facts.

The Intergovernmental Panel on Climate Change (IPCC) has gathered and compiled data showing the correlation between the rise in CO2 levels an rising global temperatures. Research shows that since the beginning of the Industrial Revolution, three-quarters of atmospheric warming has been caused by anthropogenic sources.[i]  Although there is a natural greenhouse effect, anthropogenic CO2 emissions have caused an enhanced greenhouse effect, which leads to the atmospheric warming that is occurring.  Those who deny climate change are merely choosing to ignore the data because it is not to their economic benefit to accept the reality of climate change. 
The Greenhouse Effect


According to the IPCC, the total average temperature increase from 1850-1899 to 2001-2005 was .76°C.  The general consensus amongst scientists is that a 2°C change in global temperatures could lead to catastrophic effects and extreme sea level rise which would submerge several island nations.  Furthermore, if emissions stayed at 2000 levels, a further warming of 1° degree would be expected for the next two decades.[ii] 

Emissions levels have increased greatly beyond 2000 levels and will continue to rise unless urgent measures are taken to stop them.  The National Oceanic and Atmospheric Administration’s records show the annual mean atmospheric CO2 concentration in 1960 was 316 parts per million (ppm) while the 2010 concentration was 389ppm.[iii]  This huge increase in atmospheric CO2 can be attributed mainly to anthropogenic causes and specifically industrialization.  Since 1961, observations have shown that the average temperature of the global ocean has increased to depths of at least 3000 meters and the ocean has been absorbing more than 80% of the heat added to the climate systems.  The IPCC has measured sea-level rise over the 20th century at .17 meters.[iv] 

At the current rate of emissions, climate change and sea level rise is happening at an increasing rate.  Preventing global temperatures from rising above 2°C only lowers the chance of the extreme effects of climate change occurring to 50%. 

There is no time to wait. Action needs to be taken now.

The effects of climate change will be felt by everyone but most heavily in states that do not have the economic resources to adapt.  The countries that will be least affected are also the ones that have contributed the most to greenhouse gas emissions.  For example, the United States is responsible for approximately 25% of global greenhouse gas emissions (2009 statistic) but has the capacity and resources to adapt to climate change better than other nations.[v]  Small island nations, like the Maldives, will face flooding and coastal erosion and the displacement of their people due to rising sea levels.  Warmer, drier conditions will threaten agriculture, especially in many African regions where food supply is already short.[vi]  Overall, the entire world will be affected by climate change but developing nations will be hit harder than other places due to their decreased economic and social resilience.  That is what makes climate change a truly global issue, which is why I chose to examine what can be done at an international level.

Action needs to be taken now to prevent detrimental climate change.  In order to stay below a 2°C increase in global temperature, greenhouse gas emissions need to peak by 2015.  A 2°C increase is what climate scientists believe to be the maximum temperature increase the Earth can sustain without catastrophic effects.[vii] 



Here’s how it would work:

A successful treaty would require a commitment to providing clean and safe energy for all through clear implementation measures, funding provisions, and enforcement mechanisms. Governments need to commit to making the switch to renewable energies.  In addition, governments and businesses need to commit to zero deforestation by 2020.  This can only be achieved by addressing the demand-side causes of deforestation.  When a truly fair and just Green Economy is established, the economy will be a tool to deliver societal goals rather than economic growth itself being the end goal.[viii] 

Together with the European Renewable Energy Council, Greenpeace developed the Energy Revolution, a plan that demonstrates the ability to achieve a fair and just Green Economy.  The Energy Revolution would cut emissions by more than 80% by 2050, deliver energy to people currently without it, and create more jobs.[ix]  The Energy Revolution requires an ambitious energy efficiency program along with massive development of renewable energy.  If implemented effectively, 95% of the global energy system could be powered by renewable energy and energy could reach more people in remote locations through a decentralized system.  The founding principles of the Energy Revolution are 1) increasing human well-being without fossil fuels, 2) fair energy access for all, 3) respect for natural limits, and 4) phasing out dirty, dangerous fuels like coal and nuclear by using proven existing renewable energy.[x] 

The amount of renewable energy that is technically accessible is enough to provide six times more power than the world currently consumes, and it will never run out.[xi]  The renewable sources included in the Energy Revolution are wind, biomass, passive and active solar, geothermal, and ocean and hydroelectric power. 



The key to successfully implementing renewable energy is decentralized energy systems where power and heat are produced closer to the final point of use, which avoids the current waste of energy spent transporting energy.[xii]  This will require infrastructure investments for smart interactive grids, supergrids which can transport large quantities of offshore wind power, and clusters of renewable microgrids and similar mechanisms.[xiii]  Although initial investments are required, renewable energy is the only option for the future because we will eventually run out of non-renewable energy sources.  Currently fossil fuel energy is made available at a lower cost than it actually should be due to subsidies.  If social externalities were considered, renewable energy would be just as affordable as fossil fuels if not more.

Due to the initial infrastructure costs, the Energy Revolution can only become a reality if developing nations are given funding for these investments.  Greenpeace developed the Greenhouse Development Rights framework to deal with this.  Designed by EcoEquity and the Stockholm Environmental Institute, it provides a mechanism for calculating the national shares of obligations for financing the Energy Revolution based on two factors: responsibility, or their contribution to climate change, and capacity, their ability to pay.[xiv]  This emphasizes the polluter-pays principle and the shared but differentiated responsibilities principle as rich countries will be responsible for increasing the proportion of renewables more so than poor countries.

For example, based on a responsibility and capacity indicator, the US accounts for 36.8% of the world’s responsibility for climate change and therefore would be responsible for funding 36.3% of the required global emissions reductions (given that it also has the capacity to pay that share).  Through the Greenhouse Development Rights framework, industrialized countries can help developing countries ‘leapfrog’ into sustainable energy.[xv] 

The Energy Revolution would require the following policy changes:
1)    Phase out all subsidies for fossil fuels and nuclear energy.2)    Internalise the external (social and environmental) costs of energy production through ‘cap and trade’ emissions trading.
3)    Mandate strict efficiency standards for all energy consuming appliances, buildings and vehicles.
4)    Establish legally binding targets for renewable energy and combined heat and power generation.
5)    Reform the electricity markets by guaranteeing priority access to the grid for renewable power generators.
6)    Provide defined and stable returns for investors, for example by feed-in tariff programmes.
7)    Implement better labelling and disclosure mechanisms to provide more environmental product information.
8)    Increase research and development budgets for renewable energy and energy eficiency.[xvi] 

Currently conventional energy sources receive approximately $250-300 billion in subsidies per year globally.[xvii]  This results in artificially low prices for conventional energy sources, which makes renewable energy less desirable.  If subsidies are eliminated and the externalities of conventional energy sources, such as the cost of climate change damage, were factored in, renewables would be competitively priced.  To implement the Energy Revolution in industrialized countries, subsidies for conventional energy would need to be eliminated and the money saved needs to be put towards investments in renewable energy technologies and infrastructure.  To make renewables affordable for consumers there are several options including tax credits, rebates, and loans for using renewable energy instead of conventional energy, installing solar panels, etc.[xviii] The capital and technology is available to make the Energy Revolution, it simply requires states to acknowledge climate change mitigation as a top priority.

Implementation in developing countries would require financial support from developed nations to help bridge the gap from existing infrastructure to a more sustainable future.  The Greenhouse Development Rights framework previously discussed would determine the level of contributions from each nation and the financial resources can come from a variety of sources including the Copenhagen Green Climate Fund.[xix] 

Greenpeace proposes the Feed-in Tariff Support Mechanism (FTSM), which would help with initial investment costs.  The FTSM will be supported by a bankable support scheme, which will lower costs by reducing risk for investors and equipment suppliers.[xx]  Bankable support schemes have proven to be the most efficient and successful mechanism for supporting renewable energy.  For example, in Germany, where there is a bankable support system, wind-powered electricity is 40% cheaper than in the United Kingdom.[xxi] 

However the FTSM still leaves consumers with a slightly higher electricity cost than current conventional energy costs.  Cost is the major obstacle in executing the Energy Revolution in developing countries, which is where the financing from the Greenhouse Development Rights framework would come in. 

The goal of the Energy Revolution is to reduce CO2 emissions to 10 gigatonnes per year by 2050 and phase out nuclear energy.  Currently renewables account for 13% of the world’s primary energy demand and with the Energy Revolution, by 2050 80% of the primary energy demand can be supplied by renewable sources.[xxii]

In addition to climate change mitigation, 3.2 million more jobs can be created by 2030 through the policies Greenpeace is promoting, thereby effecting a secondary positive social benefit.[xxiii] 

Sufficient renewable energy and other solutions to climate change exist; the missing component is making the switches mandatory and economically viable.  The Energy Revolution provides the tools to accomplish this.  

Although there are many different plans for climate change mitigation, I particularly like Greenpeace’s Energy Revolution because it addresses an array of issues related to climate change, in particular, the need for different levels of contribution.  It is highly unlikely that the Energy Revolution will be taken into effect any time soon considering the nature of government; however, it shows how climate change mitigation is feasible.  Once people begin to realize the necessity and feasibility of climate change mitigation, there will be more pressure on governments to make changes in their policies and we can work towards a Green Economy.
