Indication: The emission of greenhouse gases affecting our climate - measured as CO2-eq - is a good indicator for the long-term ecological effects of our actions, but by no means a perfect one.
The CO2-eq very accurately reflects the use of non-renewable fossil fuels as an energy source. It also takes into account the destruction of natural ecological systems, e.g. the destruction of large tracts of CO2-absorbing forests, and the emission of other greenhouse gases, such as methane. This allows us to trace the climate effects of the various stages of food production quite well.
Other aspects, which are also important for our climate, are not accurately reflected by the CO2-eq, such as nuclear energy use, ecological diversity and many others.
Nevertheless, we believe that at present the CO2-eq is a suitable measure to make us aware of the magnitude of climate effects and damage our lifestyle causes to our planet. As soon as more accurate measures emerge, “a better day the 100 way” will take these on board.
Our climate is changing. The average temperatures of the air and the oceans have increased, polar ice and glaciers are melting and sea levels are rising. There have always been changes in climate; what is new is that humans are actively driving this current rapid change. Human action and increasing industrialisation have been shown to be partly responsible for the climatic changes around the world.
Global warming is mainly driven by the so-called greenhouse gases, which are produced in large amounts as a result of our industrialised lifestyle and economy. The amount and concentration of greenhouse gases in our atmosphere is usually specified as CO2-equivalent (CO2-eq). This value corresponds to the amount of carbon dioxide or CO2, the most important greenhouse gas, that has the same greenhouse effect as all the greenhouse gases combined. The CO2-eq allows us to express the greenhouse effect of goods, activities, transport, production, lifestyle choices etc. in a single value.
Currently, 6.8 kg (15 lbs) is the amount of CO2 each person on this planet may emit on a daily basis by how they live, in order to keep our climate in balance. We convert this amount to 100 points. Every single day, each person has 100 points at their disposal.
