Pros and Cons of Fossil Fuels
Used for centuries, fossil fuels have played a vital role in every individual’s life. It has been used for domestic and industrial purposes all across the world. Alike any other thing, it also has some advantages and disadvantages. Fossil fuels are the derivative of plant and animal fossils. As the name suggests, these are made from organic remains or decay of plants and animals. These ...

Support for fossil fuels remains high but the time is ripe for change
Government support to fossil fuel consumption and production in OECD countries and key emerging economies remains high, at USD 160-200 billion annually, according to a new OECD report. This support is hampering global efforts to curb emissions and combat climate change. The OECD Inventory of Support Measures for Fossil Fuels 2015 takes stock of almost 800 spending programmes and tax breaks used ...

Chapter 8: Optimal economic growth when CO2 constraints are critical
Past analyses of optimal economic growth behaviour have neglected the constraints of fossil fuel production and the accumulation of atmospheric CO2 having a negative impact on production and productivity, as pursued in the more general context of Chapter 7. The factors of production have been assumed to be either self-regenerating (labour) or augmentable via production (capital) or technical ...

Carbon Dioxide Emissions from Fossil Fuels and Cement Reach Highest Point in Human History
We already know the world’s carbon budget is being exhausted at an alarming pace, but a new scientific assessment reveals just how sobering the picture of the global carbon cycle truly is. The Global Carbon Project’s (GCP) 2013 report finds that at the precise time emissions reductions are needed most, carbon dioxide (CO2) emissions from burning fossil fuels and producing cement have ...

Air quality and health research in a province producing oil and gas
The Canadian province of Alberta is a major world producer of oil and gas. It is therefore vested in issues of air quality and health, which are in turn driven by fossil fuel combustion. The scientific community within the province provides the capacity to address these issues and in order to remain current needs to be actively engaged in research. Air quality is generally very good in Alberta. ...

Green transportation: need, technology and challenges
Internal combustion (IC) engine based vehicles are the backbone of the modern transport sector. These vehicles use fossil fuels as a source of energy to propel it and emit toxic gases. These noxious gases harm the environment and causes human health problems. Hasty usage of fossil fuels results in rapid depletion of these resources and price inflation. These concerns encourage the modern society ...

An empirical study on the interaction between EUA futures, coal, natural gas and electricity
This paper uses a Vector Error Correction Model (VECM), a method to estimate the adjustment speed of variables toward their long–run relationship in the short run, to investigate the dynamic relationship between the prices of EUA, coal, natural gas and electricity futures. It finds that there is a long–run equilibrium relationship between them. Short–run relationships between them are also ...

Unabated Coal Use Will Break World’s “Carbon Budget”
While many people are traveling to Warsaw this week to participate in the international climate negotiations (COP 19), the city is also hosting another global conference: the International Coal and Climate Summit. It’s a troubling juxtaposition—coal contributes to 43 percent of global greenhouse gas emissions, making it a major driver of climate change. In fact, a new statement ...

CO2 emissions accelerated rapidly between 2000 & 2006
Global carbon dioxide (CO2) emissions from the burning of fossil fuels stood at a record 8.38 gigatons of carbon (GtC) in 2006, 20 percent above the level in 2000. Emissions grew 3.1 percent a year between 2000 and 2006, more than twice the rate of growth during the 1990s. Carbon dioxide emissions have been growing steadily for 200 years, since fossil fuel burning began on a large scale at the ...

British scientist claims CCS is the solution of climate change
Oxford professor argues that climate change can be solved by forcing the fossil fuel industry to implement CCS to bury their waste products. Climate change can be solved by making all producers of carbon-based fuels accountable for the disposal of the carbon dioxide their fuels ultimately give off as a condition of remaining in business. This was the proposal put forward last week by one of ...

A structural decomposition analysis of air pollution from fossil fuel combustion in India
During the last decade, there has been worldwide concern with global climate change, which has been induced by greenhouse gases (GHGs) due to the use of fossil fuels. The CO2 emissions from fossil fuel combustion have been identified as the single most significant source of GHG emissions into the atmosphere. Realising the need to control and regulate emissions of pollutants, the objective of the ...

Global environmental impacts of the hydrogen economy
Hydrogen-based energy systems appear to be an attractive proposition in providing a future replacement for the current fossil-fuel based energy systems. Hydrogen is an important, though little studied, trace component of the atmosphere. It is present at the mixing ratio of about 510 ppb currently and has important man-made and natural sources. Because hydrogen reacts with tropospheric hydroxyl ...

The biggest hole in Australia's version of the solution to climate change - what is wrong with its carbon reduction trading scheme
In June 2009, when farmers were at last considered in the USA climate bill, attention was belatedly directed at agriculture's potential for a major contribution to carbon emission reductions. The official line (Department of Climate Change, 2009) ignores the environmental effect of traditional farming methods in terms of desertification, soil degradation, water management and warming. Alternative ...
