C．Recording the highest temperature in a year.
D．Negotiating a new treaty for reducing the emissions.
less popular airports was a much cheaper alternative to the major city airports and supported Airtite’s low cost service,
modelled on existing low cost competitors. These providers had effectively transformed air travel in Europe and, in so
doing, contributed to an unparalleled expansion in airline travel by both business and leisure passengers. Airtite used
one type of aircraft, tightly controlled staffing levels and costs, relied entirely on online bookings and achieved high
levels of capacity utilisation and punctuality. Its route network had grown each year and included new routes to some
of the 15 countries that had joined the EU in 2004. Airtite’s founder and Chief Executive, John Sykes, was an
aggressive businessman ever willing to challenge governments and competitors wherever they impeded his airline and
looking to generate positive publicity whenever possible.
John is now looking to develop a strategy which will secure Airtite’s growth and development over the next 10 years.
He can see a number of environmental trends emerging which could significantly affect the success or otherwise of
any developed strategy. 2006 had seen fuel costs continue to rise reflecting the continuing uncertainty over global
fuel supplies. Fuel costs currently account for 25% of Airtite’s operating costs. Conversely, the improving efficiency of
aircraft engines and the next generation of larger aircraft are increasing the operating efficiency of newer aircraft and
reducing harmful emissions. Concern with fuel also extends to pollution effects on global warming and climate
change. Co-ordinated global action on aircraft emissions cannot be ruled out, either in the form. of higher taxes on
pollution or limits on the growth in air travel. On the positive side European governments are anxious to continue to
support increased competition in air travel and to encourage low cost operators competing against the over-staffed
and loss-making national flag carriers.
The signals for future passenger demand are also confused. Much of the increased demand for low cost air travel to
date has come from increased leisure travel by families and retired people. However families are predicted to become
smaller and the population increasingly aged. In addition there are concerns over the ability of countries to support
the increasing number of one-parent families with limited incomes and an ageing population dependent on state
pensions. There is a distinct possibility of the retirement age being increased and governments demanding a higher
level of personal contribution towards an individual’s retirement pension. Such a change will have a significant impact
on an individual’s disposable income and with people working longer reduce the numbers able to enjoy leisure travel.
Finally, air travel will continue to reflect global economic activity and associated economic booms and slumps together
with global political instability in the shape of wars, terrorism and natural disasters.
John is uncertain as to how to take account of these conflicting trends in the development of Airtite’s 10-year strategy
and has asked for your advice.
Required:
(a) Using models where appropriate, provide John with an environmental analysis of the conditions affecting the
low cost air travel industry. (12 marks)
As environmentalists convene in Rio de Janeiro this week to ponder the global climate of the future, earth scientists are in the midst of a revolution in understanding how climate has changed in the past-and how those changes have transformed human existence. Researchers have begun to piece together an illuminating picture of the powerful geological and astronomical forces that have combined to change the planet&39;s environment from hot to cold, wet to dry and back again over a time period stretching back hundreds of millions of years.
Most important. scientists are beginning to realize that the climatic changes have bad a major impact on the evolution of the human species. New research now suggests that climate shifts have played a key role in nearly every significant turning point in human evolution: from the dawn of primates(灵长目动物) some 65 million years ago to human ancestors rising up to walk on two legs. from the huge expansion of the human brain to the rise of agriculture. Indeed, the human history has not been merely touched by global climate change, some scientists argue, it has in some instances been driven by it.
The new research has profound implications for the environment summit in Rio. Among other things, the findings demonstrate that dramatic climate change is nothing new for planet Earth. The benign(宜人的) global environment that has existed over the past 10,000 years-during which agriculture. writing, cities and most other features of civilization appeared-is a mere bright spot in a much larger pattern of widely varying climate over the ages. In fact, the pattern of climate change in the past reveals that Earth&39;s climate will almost certainly go through dramatic changes in the future-even without the influence of human activity.

Which Low Carbon Technology Is Now a Reality？
A．With fossil fuels expected to supply over 70% of the world"s energy needs by 2040， we face some urgent questions: where should efforts be focused in reducing greenhouse gas emissions？ Which technologies hold the most promise？ There are a range of low-carbon solutions and given the challenge， we will need them all．We hear a lot about the advances being made by refreshable sources of energy such as solar， wind and hydro-electricity and these are certainly valuable technologies in combating climate change．But how can we really make a m jor impact in reducing carbon emissions from large power plants and industrial facilities？ Enter carbon capture and storage——or CCS——a technology that captures CO2 from fossil fuel production and permanently stores it underground．
B．The aim is to prevent the release of large quantities of CO2 into the atmosphere （from fossil fuel use in power generation and other industries ）．It is a potential means of relieving the contribution of fossil fuel emissions to global warming and ocean acidification （酸化）．Although CO2 has been injected into geological formations for several decades for various purposes， including enhanced oil
recovery， the long term storage of CO2 is a relatively new concept．The first commercial example was Weyburn in 2000．CCS can also be used to describe the scrubbing （涤气 ） of CO2 from environmental air as a climate engineering technique．
C．In November 2014 the Global CCS Institute released its flagship （核心的） publication——the annual Global Status of CCS report．This comprehensive annual update is the prominent source of information on the development of CCS around the world．A lot of work went into updating information in the report， in cooperation with the CCS industry， as there had been quite significant changes to the CCS landscape in the preceding 12 months．This included the launch of a large-scale
CCS project in the power sector and the beginning of construction of the world"s first large-scale CCS project in the iron and steel sector．
D．Large-scale CCS is now a reality in the power sector with the October 2014 launch of the Boundary Dam Integrated Carbon Capture and Storage Demonstration Project in Saskatchewan， Canada．Boundary Dam is the first commercial CCS plant in the power sector， removing 90 per cent of the CO2 produced by electricity generation from lignite （褐煤） coal at Production Unit No．3 of the SaskPower facility．The captured CO is primarily used for enhanced oil recovery （EOR） at the nearby Weyburn oil field， although amounts are also to be stored in deep geological formations at the Aqnistore site．The success of the Boundary Dam project and the progression of additional
projects through planning and construction， indicates that CCS technologies for application in the power sector are "market ready"．
E．The next 18 -24 months will see CCS be applied across a range of industries and storage types．A further two large-scale CCS power projects are in construction in the US——the Kemper County Energy Facility in Mississippi and the Petra Nova Carbon Capture Project in Texas．Both projects are expected to be operational in 2016．Also in the US， the Illinois Industrial CCS project planned for launch later this year will capture CO2 from the Archer Daniels Midland corn-to-ethanol （乙醇） plant in Decatur， Illinois for storage in an onshore deep saline formation．The Abu Dhabi CCS project in the United Arab Emirates is under construction and from 2016 will provide the world"s first large- scale demonstration of CO2 capture from iron and steel production．
F．In addition to the 22 large-scale CCS projects currently in operation or construction around the world，14 projects are in advanced stages of planning， many of which are likely to be in a position to make a final investment decision over the coming year．Together this group of projects covers a range of applications for CCS and could extend to around ten in the number of large-scale CCS projects operating in the power sector by the end of the decade．Their progression to operation would add experience in the dedicated geological storage of CO．and see operational large-scale CCS activity extend to China for the first time．
G．2014 saw commercial application in the power sector become a reality and we can look forward to a further expansion across a diverse range of industries in the coming years．The Global CCS Institute continues to cover developments in CCS with up-to-date information， expert insights， workshops， media releases and online seminars．We struggle to make CCS industry information easily accessible and encourage you to engage with us via our website and regular publications．
H．For detailed information on large-scale CCS projects please visit our online Projects page， which you can browse or search for projects based on stage， region， industry o．r capture， transport and storage type．For the first time the Institute"s website contains project descriptions for around 40 lesser scale "remarkable" CCS projects， of which four Japanese "remarkable" CCS projects were the key focus of a chapter in the Global Status of CCS report．For ongoing expert information visit our Insights page， which is regularly updated with articles from experts in carbon capture and storage， public engagement， legal issues and policy developments．
I．To join in the discussion you can attend meetings and workshops around the world， and participate in online seminars where you will have the opportunity to listen to and ask questions of a range of experts．Visit our Events page to see upcoming meetings， conferences， workshops and seminars．Finally， for a range of up-to-date news and more detailed information， visit our news and publications sections．We look forward to covering this exciting period in the development of CCS and providing you with the latest information and important issues for the sector．
Carbon dioxide has been stored in geological formations for different purposes； however， its long term storage is comparatively new． 查看材料
However, in spite of buoyant stock markets over the last couple of years, Mezza Co’s share price has remained static. It is thought that this is because there is little scope for future growth in its products. As a result the company’s directors are considering diversifying into new areas. One possibility is to commercialise a product developed by a recently acquired subsidiary company. The subsidiary company is engaged in researching solutions to carbon emissions and global warming, and has developed a high carbon absorbing variety of plant that can be grown in warm, shallow sea water. The plant would then be harvested into carbon-neutral bio-fuel. This fuel, if widely used, is expected to lower carbon production levels.
Currently there is a lot of interest among the world’s governments in finding solutions to climate change. Mezza Co’s directors feel that this venture could enhance its reputation and result in a rise in its share price. They believe that the company’s expertise would be ideally suited to commercialising the product. On a personal level, they feel that the venture’s success would enhance their generous remuneration package which includes share options. It is hoped that the resulting increase in the share price would enable the options to be exercised in the future.
Mezza Co has identified the coast of Maienar, a small country in Asia, as an ideal location, as it has a large area of warm, shallow waters. Mezza Co has been operating in Maienar for many years and as a result, has a well developed infrastructure to enable it to plant, monitor and harvest the crop. Mezza Co’s directors have strong ties with senior government officials in Maienar and the country’s politicians are keen to develop new industries, especially ones with a long-term future.
The area identified by Mezza Co is a rich fishing ground for local fishermen, who have been fishing there for many generations. However, the fishermen are poor and have little political influence. The general perception is that the fishermen contribute little to Maienar’s economic development. The coastal area, although naturally beautiful, has not been well developed for tourism. It is thought that the high carbon absorbing plant, if grown on a commercial scale, may have a negative impact on fish stocks and other wildlife in the area. The resulting decline in fish stocks may make it impossible for the fishermen to continue with their traditional way of life.
Required:
Discuss the key issues that the directors of Mezza Co should consider when making the decision about whether or not to commercialise the new product, and suggest how these issues may be mitigated or resolved.
