Rice straw open burning is the most common form of agricultural by-product treatment in developing countries. Contaminated pollutants pollute the environment, badly affect human’s health and contribute to the increase of greenhouse gases that impact climate change.

This research explores whether Environmental Management Accounting can be applied to assist an Australian cogeneration company in improving both its financial performance as well as its environmental performance. Cogeneration or ‘combined heat and power’, in this particular case, involves the simultaneous production of heat and electricity using a single fuel, that is, natural gas. The heat generated is then used to produce steam to meet the customers’ requirements as well as boost the production of electricity.

How aggressively and in what way should society take action to reduce damages from climate change? In this course we will examine the balance between expected impacts and their costs one hand and policy options and their costs on the other. We will consider mitigation options to reduce future climate change, as well as adaptation alternatives to prepare for the changes that do occur.

Soil organic carbon (SOC) pool is the largest among the terrestrial pools. The restoration of SOC pool in arable lands represents a potential sink for atmospheric CO2. The management and enhancement of SOC is important for sustainable agriculture. The cropping system and soil type influence crop biomass under different fertilization. Agriculture acts as both the sink and sources of the greenhouse gases.

Methanosarcina mazeibelongs to the group of aceticlastic methanogens and converts acetate into the potent greenhouse gases CO2 and CH4. The aceticlastic respiratory chain involved in methane formation comprises the three transmembrane proteins Ech hydrogenase, F420 nonreducing hydroge-nase and heterodisulfide reductase.

Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace. It's becoming clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than in the last 650,000 years.

Definition “The earth is a natural greenhouse and is kept warm by water vapors, carbon dioxide (CO2), and other gases in the atmosphere, which absorb the sun’s energy and radiate it back toward the earth. This type of warming is called ‘natural greenhouse effect’. ‘Enhanced greenhouse effect’, on the other hand, causes global warming due to excessive levels of CO2 in the atmosphere.” Facts Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.

Climate change is a very real and urgent global issue. Its consequences are being experienced every day. We read about it in newspapers, hear it debated in Parliament and our children learn about it in school. It’s a problem we all share, because every single country will be affected. Together, today, we must take action to adapt to it and stop it — or, at least, slow it down. your essential guide It’s now clear that the emission of man-made greenhouse gases is causing climate change. The rate of change began as significant, has become alarming and is simply unsustainable in the...

The earth’s atmosphere is made up of a delicately balanced layer of ‘greenhouse gases’. This layer acts like a blanket, trapping enough heat to sustain life. Humans are burning huge amounts of fossil fuels – adding more and more greenhouse gases to the atmosphere and making this blanket thicker. This traps more and more heat, warming the globe and throwing our climate into chaos. Climate change is already underway. The most recent (2007) report of the world’s most authoritative body of climate scientists, the Intergovernmental Panel on Climate Change (IPCC)1, confi rmed that:2...

Climate change is one of the most urgent issues of our time. It is the greatest environmental challenge we face today as a global community. Photo: Flooding in Boscastle, Cornwall, 2004 An indication of the type of event that scientists say will become more frequent in the future. .Given the enormity of the problem of climate change and its consequences – heatwaves, flooding, more frequent storms – people may find it hard to believe that they can do anything to help.
