The line graph compares the waste output, measured in tonnes, of three different corporations over a period of 15 years from 2000 to 2015. Overall, it is clear that Companies A and B experienced a decrease in waste, while the amount of waste produced by Company C increased significantly.
In 2000, Corporation A recorded the highest waste output at 12 tonnes, which was one and a half times greater than that of Corporation B and three times greater than that of Corporation C. Over the following five years, the waste output of Companies B and C increased to approximately 10 and 6 tonnes, respectively, while the amount of waste produced by Company A declined by about 1 tonne.
From 2005 to 2015, the waste output of Corporations A and B decreased. In 2005, Company A produced 9 tonnes of waste, which was 6 tonnes more than Company B. In contrast, the amount of waste generated by Corporation C surpassed that of Corporation B, reaching 7 tonnes in 2010.
