Energy cost of various construction materials
CO2 emissions are not directly deducible from energy costs. Concrete for instance is a very CO2-intensive material due to the emissions from chemical processes involved in its production, despite the relatively low energ...

Strategic options for climate change mitigation Global cost curve for greenhouse gas abatement measures
This graphic attempts to show 'all in one': the various measures for greenhouse gas reduction with both reduction (in CO2 equivalent) and cost (in Euros) quantified. Read from left to right it gives the whole range of s...

Some examples of the effect of individual behaviour on greenhouse gas emissions in France
The area of the squares is proportionate to the annual reduction in emissions in million tonnes of CO2 equivalent. Estimated values calculated by France's Environment Institute (Ifen), drawing on various sources: Mani...

Biological oxygen demand - BOD: 1976-2008
The availability of oxygen is one of the most important indicators of the condition of a water body, because dissolved oxygen, or DO, (the amount of oxygen dissolved in water) is necessary for most aquatic organisms, inc...

Industrial areas and seasonal zones of oxygen depleted waters
This graphic illustrates the strong link between areas with high densities of industrial activity and zones of seasonally oxygen-depleted waters. There is a strong link between areas with high densities of industrial ac...
