The steady increase in carbon dioxide concentrations in the atmosphere come from our use of fossil fuels. If we were able to stop using fossil fuels, the amount of carbon dioxide in the atmosphere would stop rising. Biofuels are a partial answer, because by using biofuels you are reducing our use of fossil fuels.

Why are biofuels important?
Biofuels are important because they are a renewable resource, whereas there are limited reserves of carbon based fuels. Biofuels are also responsible for fewer carbon dioxide emissions.
What is produced when biofuels are burned?
carbon
How can you lower your carbon emissions?
By reducing your lifestyle, example consuming electricity causes C02
What are the advantages of biofules?
The aim of all biofuels is to be carbon neutral. They reduce greenhouse gas emissions when compared to conventional transport fuels. In reality, biofuels are not carbon neutral simply because it requires energy to grow the crops and convert them into fuel. The amount of fuel used during this production (to power machinery, to transport crops, etc) does have a large impact on the overall savings achieved by biofuels. However, biofuels still prove to be substantially more environmentally friendly than their alternatives. In fact, according to a technique called Life Cycle Analysis (LCA) first generation biofuels can save up to 60% of carbon emissions compared to fossil fuels. Second generation biofuels offer carbon emission savings up to 80%. This was backed by a recent UK Government publication which stated biofuels can reduce emissions by 50-60%. Another advantage of biofuels is that they save drivers money. The UK Government in particular has introduced many incentives to drivers of 'green cars' based on emissions - with reduced taxation dependent on how environmentally friendly your vehicle is. With petrol prices on the rise, replacing petroleum with a renewable energy source should also offer significant savings at the pump in the long term, particularly when biofuels are more readily available. There are arguments too that biofuels are helping to tackle poverty around the world. For example, the Overseas Development Institute has pointed to wider economic growth and increased employment opportunities along with the positive effect on energy prices, as reasons to back biofuel production. This is debated due to the pressures it places on agricultural resources but biodiesel could be a long term solution as it uses simpler technology and lower transportation costs alongside increased labour. © Copyright 2000-2009 Really Good Domains Ltd.

What is the difference between carbon credits and Certified emissions rate?
Certified emission rates are a limit on the amount of emissions a company can release into the atmosphere within a given time frame. It is a cap on the emissions itself.Carbon credits looks more at the net carbon emissions. There are companies that plant trees, which reduce the amount of carbon in the air. For their good deeds, they get carbon credits, which they sell to companies that emit carbon. The carbon credits work to offset the actual amount of emissions a company puts out.Note that carbon credits cancel out the emissions, but don't lower emissions at all, unlike a cap on emission rates.
Do Bio Fuels release sulfur dioxide?
Yes. I do not like using links from companies related to the biofuels industry, but in this case, I could not find any other information on the internet about how much sulfur dioxide is released from burning biofuels. It does get complicated, as there are all types of biofuels. The biofuels are reported as contributing much less air pollutants than diesel or gasoline, but they are not carbon (or sulfur dioxide, nitrogen oxide) neutral or zero emissions.
Why do biofuels not contribute to global warming even though burning biofuels releases carbon dioxide?
Biofuels are part of the natural carbon cycle, in which plants absorb carbon dioxide from the air and this becomes carbon which is eventually returned to the air when vegetation rots or is burnt, or when animals eat it and respire carbon dioxide back into the air. Thus, although burning of wood and biofuels does release carbon dioxide back into the air, this process does not add to the long term concentration of atmospheric carbon dioxide. When we create carbon dioxide from carbon that has been sequestered underground, we add new carbon dioxide to the air, increasing its concentration and causing global warming.
Is the catalytic converter part of the emission system?
Yes it is part of the emissions system. It turns exhaust into lower emissions by burning any unburnt exhaust gases thus reducing unwanted emissions and Carbon Monoxide.
How do carbon emissions exemplify the tragedy of the commons?
Carbon emissions are not related to the tragedy of the commons. There are not any studies that confirm that carbon emissions contributed in any way.
Why would it help the environment to reduce the speed on motorways up to 70mph?
it wouldn't do much i guess it will lower carbon emissions
Is biofuel good for the environment?
Generally I would say that it is good for the environment. The biodiesel reduces the emissions of carbon dioxide by over 50 percent, driving down the pollution in the air. That is because the biodiesel emissions are from recycled carbon that was already in the atmosphere. The biodiesel also has a lot less hydrocarbons. In fact, there are venture capitalist investing large amount of money on biofuels. Read more, click the link.
What are a Zero carbon house designs?
Zero-carbon house designs refer to architectural, construction and engineering designs intended to lower down carbon emissions. These designs are also known as sustainable designs.
