The line chart illustrates the amounts of waste produced by three different companies, A, B, and C, over a 20-year period from 2000 to 2020. Units are measured in tonnes.
Overall, Companies A and B showed a clear reduction in the waste they generated, while Company C experienced a steady increase in its waste output during the same period.
In 2000, Company A generated the most waste at 12,000 tonnes, which then saw a consistent decline to 6,000 tonnes by 2020. Similarly, Company B started at 8,000 tonnes in 2000 and its waste production decreased steadily, reaching 3,000 tonnes by the end of the period, making it the company with the least waste produced in 2020.
Conversely, Company C began with the lowest waste figure of 4,000 tonnes in 2000. Its waste generation increased consistently over the two decades, eventually reaching 8,000 tonnes in 2020. This meant that by 2020, Company C was producing more waste than both Company A and Company B.
