The graph shows the change in emissions of acidifying pollutants (sulphur dioxide SO2, nitrogen oxides NOx and ammonia NH3) each weighted by an acid equivalency factor prior to aggregation to represent their respective acidification potentials. The acid equivalency factors are given by: w(SO2) = 2/64 acid eq/g = 31.25 acid eq/kg, w(NOx) = 1/46 acid eq/g = 21.74 acid eq/kg and w(NH3) = 1/17 acid eq/g = 58.82 acid eq/kg.

Don't buy timber from illegal trade!
Illegal trade in tropical timber contributes to forest destruction. Many hardware suppliers are now selling timber that has been certified as legal and sustainable. Next time you shop for wood-products, check for labels such as the Forest Stewardship Council (FSC).
