What the numbers say
In 2021, Sierra Leone's adjusted savings, carbon dioxide damage (current US$) rose 11.1% on 2020 (from US$37.23 million to US$41.38 million).
Across the 30 yearly changes before that (1991 to 2020), the average change was +9.7% and a typical year strayed about 21.2% from that (the standard deviation). This year's change was 0.1 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.
On record, the biggest yearly rise was 72.5% in 2000 and the biggest yearly fall was 28.4% in 1995. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
From 2012 to 2021 the straight-line trend is upward, about US$939,657 a year. A straight line explains 49% of the movement over 10 observed years.

What this measures
Cost of damage due to carbon dioxide emissions from fossil fuel use and the manufacture of cement, estimated to be US$40 per ton of CO2 (the unit damage in 2017 US dollars for CO2 emitted in 2020) times the number of tons of CO2 emitted. This indicator is expressed in current prices, meaning no adjustment has been made to account for price changes over time. This indicator is expressed in United States dollars.
