Various factors are taken into consideration when calculating flight emissions and their impact on the environment. The following are the main ones: The type of aeroplane, how much fuel it uses, the number of seats it has and how many are first class (first class seats take up more room than economy seats, and the more there are the fewer passengers the aeroplane carries).

This is a hard one, as the National Energy Foundation admit, there are all kinds of variables involved. I used 0.18 kg per mile for a long distance flight, for shorter distances a figure of up to 0.3 kg per mile may apply. Climate Care www.climatecare.org, Future Forests www.futureforests.com , and the National Energy Foundation www.natenergy.org.uk/convert.htm all have excellent calculators!

come from car's real fuel consumption i.e. not according to figures provided by UTAC (Union Technique de l'Automobile du Motocycle et du Cycle), which do not take into account cold starting, air-conditioning, acceleration, traffic jams etc. The calculation for motorcycle emissions comes from a study carried out by the Ademe. See Ademe study in PDF format.

The data for CO2 emissions is based on calculations made by the Ademe and the CEREN (Centre d'?tudes et de recherches ?conomiques sur l'?nergie = Research Centre for Economic Studies of Energy) according to size, heating system, age, usage of accommodation.

The packs are calculated on the basis of 9 tonnes of CO2 emissions per person per year. This figure corresponds to France's total emissions of greenhouse gases (CO2, CH4, N20, HFC, PFC, SF6) expressed as CO2 equivalents and divided by number of inhabitants.

It’s up to you. You can calculate your emissions and arrange for an appropriate number of trees to be planted, or you can simply donate ten trees.

You will need to find our your annual mileage and fuel efficiency in miles per gallon (mpg). If you travel 10,000 miles a year and your car does 30 to the gallon, you will be using 333 gallons, which is 1,514 litres. Emissions are 2.31 kg per litre, which would give a total of 3.5 tonnes of CO2. (Diesel is 2.68 kg per litre.). If this seems complicated, I recommend the calculator at Climate Care www.climatecare.org.

Loss factors for the most common fitting types and control configurations have been developed through testing conducted by the American Petroleum Institute (API) and reviewed by EPA. The fittings tested were generic designs that approximated evaporative loss mechanisms common to most vendor components. In most cases, if the exact design is not found, one that is of similar geometry will be available and should be selected.

No. It is the responsibility of the reporting company or entity to make the emissions calculations using an approved method. Redbud is a means of collecting information for our database.

You calculate gas and electricity by adding up the KHh. (KWh appear on your utility bills.) Emissions from gas are 0.19 kg of CO2 per KWh. Emissions from electricity are 0.43 kg of CO2 per KWh. Emissions from oil (central heating) are 2.68 kg of CO2 per litre, and emissions from coal are 2.419 tonnes of CO2 per tonne of fuel.

Emissions standards also vary from state to state, and even regions within states. Most states will require that your car meet the specifications for the year of your engine. Another reason to stick with an early engine. It is usually possible to title the car as a pre-emissions vehicle as described in our REGISTRATION faq above.

Each airline will calculate its annual emissions on the basis of its fuel consumption multiplied by a standard emission factor. The proposed directive requires that, wherever possible, actual fuel consumption data for each flight should be used, but if this is not available, a standardised method for estimating fuel consumption will be used.

There are many such "carbon offset" schemes, but the accounting of how much carbon is actually taken up by the trees is very unreliable. In many cases companies are just taking your money and doing what they were going to do anyway -so it doesn't help the climate. Trees take a long time -several decades - to grow to maturity. During this time the CO2 emissions from your flight are still warming the atmosphere, and much of this heat will remain for hundreds of years in the oceans.

The final price of the ticket depends on the availability of said ticket on the stated date of the meeting (business day or weekend). We assure you that we attempt to acquire the most favourable fare-rates for our clients; we do not make a profit from airline tickets.

CardioChek Lipid Panel Test Strips will automatically calculate LDL values (require CardioChek PA analyzer). If using individual test chemistries with either CardioChek PA or CardioChek analyzers, first test Cholesterol, HDL Cholesterol and Triglycerides using new, unused test strips.

The timing of ovulation is complex and can take some studying of your body and your cycles to figure out. By using a combination of methods such as studying cervical fluid, taking your body temperature, and tracking your periods, you can calculate your time of ovulation. The American Pregnancy Association encourages women to learn about the fertility awareness method of tracking cycles and then combine that with ovulation predictor kits to best understand when you are ovulating.

When you add selections to your Bet Card, the potential payout for your bet is calculated and displayed for you automatically. If you want to understand how this calculation is made, here is how it works: Sports Interaction displays decimal prices for each outcome in an event. This price includes your bet amount. Your winnings are calculated by simply multiplying your bet amount by the displayed odds. This is the amount you will be paid if the bet wins.

Components of those emissions include carbon dioxide, nitrogen oxides, particulates (PM), carbon monoxide and volatile organic compounds, such as formaldehyde, benzene and polycyclic aromatic hydrocarbons.
