This graph displays carbon only emissions in megatonnes through to the year 2100 with various levels of immigration. The other variable is a factor representing the effectiveness of the carbon capture and storage (CCS) to curb oil sands emissions announced by the government. If the effectiveness is 100% of the government targets the differences can be compared to effectiveness rates of 50% and zero.
