Offline Carbon footprint calculator

The attached Excel sheet can be used to calculate both CO2 emissions as well as primary energy requirements for the following activities:

  • Heating with oil, gas, coal, wood, solar energy or heat pumps
  • Electricity consumption. The actual mix of power generation (coal, oil, natural gas, wood, nuclear energy, hydro energy, solar energy, wind, geothermal or waste) is taken into consideration.
  • Travelling by car for diesel and petrol fuelled cars. Either by actual fuel consumption or by distance and average fuel consumption.
  • Travelling by bus (kilometres or miles)
  • Travelling by train (kilometres or miles)

Get a feeling how mitigation of global warming can be affected

 

Run your own simulations of global warming with the attached spreadsheets!

Is prevention of global warming possible? Or is only mitigation of global warming possible? How fast do changes in the carbon dioxide emissions affect the average temperature increase? What are the effects of some proposed global warming solutions?

Global warming effects - mitigate temperature increase

Global warming solution with 1.9% reduction of CO2 emissions per year

We show the urgent need to act in order to be able to mitigate global warming. For this purpose, we simulate different scenarios for the future emissions of carbon dioxide (CO2) and calculate their effect on the rise of the average temperature on Earth.

As a result, it still seems to be possible to avoid the most devastating effects on our environment. However we must start acting immediately. The longer we are talking instead of acting, the more drastic measures are needed.

Global warming is not about the others, global warming is about us and our personal behaviour . Everyone must assume responsibility and bring down his or her personal contribution .

 

Cause and effects of global warming - IPCC report

IPCC Fourth Assessment Report "Climate Change 2007" about the cause and effects of global warming. This is the report many politicians are currently referring to and calling (at last!) for actions. A summary of the report can be found on the website of IPCC, see here .

The report does not really reveal new information about the causes and effects of global warming. This report however confirms that mankind through the emission of greenhouse gases (in particular carbon dioxide, CO2) is the cause of global warming. Mitigation of global warming will only be possible with a drastic reduction of the world-wide emission of carbon dioxide (CO2). Carbon dioxide is produced when fossil fuels (coal, oil and gas) are burned.

The important thing about this report is the fact that its findings and conclusions have been accepted by hundreds of climate experts and governments world-wide. There is no doubt any more that urgent action is needed, nobody can ignore climate change any more and call global warming "an illusion of greens".

CO2 - the major cause of global warming

Increase of world temperature
Global warming is caused by the emission of greenhouse gases . 72% of the totally emitted greenhouse gases is carbon dioxide (CO2), 18% Methane and 9% Nitrous oxide (NOx). Carbon dioxide emissions therefore are the most important cause of global warming.
Recent investigations have shown that inconceivable catastrophic changes in the environment will take place if the global temperatures increase by more than 2° C (3.6° F). A warming of 2° C (3.6° F) corresponds to a carbon dioxide (CO2) concentration of about 450 ppm (parts per million) in the atmosphere.

Cumulative CO2 emissions by country

The following graph shows the cumulative CO2 (carbon dioxide) emissions by country for the years 1900 until 2002. This is the sum of all CO2 emissions in the years 1900 until 2002 for each developed country. Data source was the World Resources Institute (WRI).

On the page link here, you can find the CO2 emissions by country and/or per capita by country .

It does make sense to look at the sum of all CO2 emissions because the lifetime of the greenhouse gases like CO2 in the atmosphere is between 50 and 200 years. The current global warming is an effect of all greenhouse gases put in the atmosphere during the last 100 years, global warming is not just caused by the greenhouse gases emitted this year or last year! This is also one of the reasons why immediate action is required to reduce the emission of greenhouse gases like carbon dioxide, because the effects of the greenhouse gases will last for about 100 years.

CO2 emissions by country

Carbon dioxide emissions per capita in the year 2002

The graph shows the total CO2 emission in million tons by country for the year 2002. Data source was the World Resources Institute (WRI). The CO2 emissions for the year 2006 are about 12 to 15% higher than the figures shown here.

The second chart shows the CO2 emissions by capita and country for the year 2002. Data source was again the World Resources Institute (WRI). Some remarks to these values:

  • The world-wide average is 4 tons of carbon dioxide (CO2) per person per year
  • The average of all industrialised nations is about 11 tons of carbon dioxide (CO2) per person per year
  • In the medium and long term, a world-wide average emission of maximum 2 tons of carbon dioxide (CO2) per person per year must be targeted. This amount is nowadays considered to be the maximum allowed quantity for a sustainable living on earth.
  • The International Energy Institute (IEA) predicts a further increase of the world-wide CO2 emissions by 55% within the next 25 years if no immediate actions to stop global warming are put in place. However, even in their alternative scenario where "... vigorous new policy measures already being contemplated.." are introduced, IEA predicts a growth of the CO2 emissions by 28% compared to 2004!

Cause and effect for global warming

Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapour, carbon dioxide (CO2), methane and ozone. Greenhouse gases are those gases that contribute to the greenhouse effect (see below). The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide.

Definition for global warming - what is global warming?

Definition of global warming: Global warming is the observed and projected increases in the average temperature of Earth's atmosphere and oceans. The Earth's average temperature rose about 0.6° Celsius (1.1° Fahrenheit) in the 20th century, see temperature graphs below.

Global warming - it's about you

Global warming causes: CO2 concentration

Global warming is a typical global phenomena, where the causer of the emission does not automatically suffer from it himself. Cause and effect are separated both in time as well as with regard to geography.

In the past, there was a more or less direct relation between the energy consumption (mainly fossil fuels) and the welfare of a country.

This makes it very difficult to reach consensus between the countries about the required steps to solve the problem. The Kyoto protocol shows that the following of the agreement will be doubtful at best if no automatic sanctions take into effect for countries violating it.

Given the severe consequences of global warming, the above sounds quite hopeless for our future. Read on to see how we all are involved in this and how we can benefit from taking our personal responsibility.
