‘Biofuels are likely to make an important contribution to a reduction in global greenhouse gas emissions.’ Evaluate this statement using the evidence provided. The opinion on biofuels is largely mixed‚ and it is questioned how effectively they will impact on the reduction of greenhouse gas emissions. The Department for Environment‚ Food and Rural Affairs [DEFRA] (2003) claim that biofuels are sustainable and renewable to a large extent‚ as they are made from recycled elements of the food chain

on each idea.) 1. Explain the economic case for implementing measures like the “pollution tax” and the “permits to pollute” to tackle the issue of emissions of greenhouse gases. [8] Explain the economic rationale of implementing “pollution tax” and “permits to pollute”: Both policies are implemented to tackle the problem of greenhouse gases‚ which causes negative externality (third party spillover effect) in the form of global warming and climate changes that lead to lower health and decreasing

INTRODUCTION Automated Greenhouse is about a design of miniature greenhouse that is equipped with the automated monitoring system. The system will constantly monitor the natural environmental conditions in the greenhouse to ensure that the plant will achieve the maximum plant growth. There are two sensors‚ which operate in the real-time‚ that will be used - temperature sensor and a humidity sensor to monitor the conditions. The microcontroller will compare the output of the sensors with the preset

Global warming is the observed increase in the average temperature of the Earth ’s near-surface air and oceans in recent decades and its projected continuation. Global warming poses an extraordinary challenge. The world ’s leading atmospheric scientists tell us that a gradual warming of our climate is underway and will continue. This long-term warming trend poses serious risks to our economy and our environment. It poses even greater risks to many other nations‚ particularly poorer countries that

Greenhouse Gases: Carbon dioxide (CO2) is a greenhouse gas in the atmosphere that may raise average temperatures on Earth. The burning of fossil fuels could be responsible for the increased levels of carbon dioxide. If current trends continue‚ future concentrations of atmospheric carbon dioxide in parts per million (ppm) could reach the levels shown in the accompanying table. The CO2 concentration in the year 2000 was greater than it had been at any time in the previous 160‚000 years. Year 2000

There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog‚ acid rain‚ the greenhouse effect‚ and "holes" in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment. One type of air pollution is the release of particles into the air from burning fuel for

Case 1.2 Green Economics Taking account of environmental costs People have become concerned by a number of environmental problems in recent years. These include: The greenhouse effect. This is caused by carbon dioxide and other gases emitted again by power stations‚ various industries and cars. The fear is that these gases will cause a heating of the Earth’s atmosphere. This will lead to climatic changes which will affect food production. It will also lead to a raising of sea levels and flooding

æ Solutions Reducing use of fossil fuels would significantly reduce the amount of carbon dioxide produced‚ as well as reducing the levels of the pollutants which cause acid rain (Solutions). This can be achieved by either using less energy in general‚ or using alternative energy sources. There are many ways to conserve energy such as: turning off any lights in a room which isn¡¦t being occupied. If you¡¦re making a short trip to the store and it is in walking distance conserve energy and take

The issue of Global climate change is one of the utmost economic‚ social‚ and environmental challenges of this century. Analysis shows that greenhouse gas emissions are responsible for changes in the pattern of climate around the Globe. “Global pollution creates a “public bad” born by all – a negative externality with a wide impact” (M.Harris‚ 2002). Australia is considered to be the driest populated continent in the world and faces stern drought and water shortages. Reducing carbon emissions is
