Hi all, I am pulling my hair out over this task, any help would be most welcome.
d) Using data from Table 2 calculate the average grams of carbon emitted per
passenger kilometre travelled for each form of transport in 2004 and
identify the modes of transport which have the highest and lowest carbon
emissions per passenger kilometre.
e) Estimate the percentage of total net carbon emissions which are due to
domestic air travel, and explain the reason for concern over the level of
emissions from air travel. table2 below.
1994 2004 (tonnes of carbon dioxide in millions)
Passenger cars 19.3 19.4
Buses 1.3 1
Railways 0.5 0.7
Civil aircraft (domestic flights) 0.3 0.6
All domestic transport 32.5 35
Net emissions in UK: all sources 152 152
International aviation 5.2 9
Table1, passenger kilometres in billions; car 678,bus 48, rail 50, air 9.8
