UPDATED – The two-week COP 21 climate conference in paris (also known as the 21st Conference of Parties to the United National Framework Convention for Climate Change ) ended on Saturday 12 December with an adopted agreement covering 195 countries, and providing a framework for voluntary efforts to significantly reduce carbon emissions starting 2020.

Those who visit the Middle East and North Africa from more temperate climates are often struck with how hot and dry the region is, and how scarce its rainfall. Some wonder why cities became established here, and how they continue to exist despite the lack of renewable freshwater.
These concerns are not entirely groundless. Yet these cities’ existence is not in any way miraculous: it’s merely an example of what can happen if cities fail to strike a sustainable balance between growth and limited resources.

Despite the increasing global interest in renewable energy sources, electricity generation remains largely dependent on fossil fuels with approximately 70% of the world’s electricity currently being generated using coal, natural gas, and petroleum products. Coal, the most carbon intensive of the fossil fuels, accounts for the largest share of electricity generated globally, with 40% of all electricity generated.
Such reliance on fossil fuels is coupled with a relatively low conversion efficiency from fossil fuels to electricity, which averages 35%. The remaining 65% of the energy contained in fuels used is in effect wasted, lost as heat in power plant turbines and generators.
In this context, it is not surprising to learn that electricity generation stands as the top contributor to global Carbon emissions. According to the International Energy Agency (IEA), electricity generation currently accounts for approximately 50% of global carbon emissions.
In the Middle East and North Africa region, electricity and heat production are responsible for 41% of total carbon emissions according to IEA data from 2009. And while not representing a consumption sector, electricity generation ranked well higher than any individual sector, including transportation, which comes second and accounts for 25% of the region’s total carbon emissions. Yet carbon emissions from electricity generation is not equal across the region. In fact, the top 5 contributors to carbon emissions from electricity generation – namely Saudi Arabia, Egypt, the UAE, Kuwait, and Iraq – together represent 70% of the region’s electricity generation carbon emissions, according to 2009 data by the IEA, a share that represents approximately 30% of the region’s total carbon emissions.

Energy use in buildings accounts globally for nearly 40% of global energy consumption and 36% of total energy-related carbon dioxide emissions. These percentages are almost equally split in two halves between the industrialized countries and the rest of the world (Price et al., 2005).
Our buildings use energy in two ways; first, to keep our interior environment comfortable through cooling, ventilation, and heating our spaces; second, to power the appliances that we have come to depend on such as home appliances, lighting systems,computers, and other office equipments. To reduce this high percentage of energy use and the resultant carbon dioxide emissions, both sources of energy use in buildings must be addressed. The first energy use can be addressed by improving the building envelope’s efficiency in order to reduce the need to condition its spaces (cooling, heating, and ventilating). This method of conserving energy use includes a vast array of passive low energy design strategies that depend on the building’s environment and context. The second energy use can be addressed by improving the efficiency of appliances and equipment used inside buildings including improving the efficiency of lighting and dissemination of improved stoves for cooking in rural areas.

In recent years much of the discussion about the impact of climate change around the world has caused a mix of anxiety and fear about the impacts this may have on human life and the environment. Many detailed studies have shown by using simulation models the impact of sea level rises on coastal cities around the world if sea level were to rise by a certain degree. These studies showed that generally speaking, it was low lying areas and river deltas that were most vulnerable, especially when these deltas are densely populated.

Relative vulnerability of coastal deltas as shown by the indicative population potentially displaced by current sea-level trends to 2050 (Extreme = > 1 million; High = 1 million to 50,000; Medium = 50,000 to 5,000 (following Ericson et al.,2006).
