No problemo. It took me a while to figure it out. The horizontal axis is NOx emissions and the vertical axis is PM (Particulate Matter) emissions. The center of the axis is 0/0 for NOx/PM. Each value is "increasing positive" in all directions. Each quadrant "belongs" to one of the nations. For each country. in different years, the regularions regarding NOx/PM emissions is becoming more restrictive, making "smaller and smaller" rectangles.
According to the graph, by 2011, for all three regions, the allowed NOx emissions will be below 1 g/KWh and the allowed PM emissions will be below 0.02 g/KWh.
