Fig. 2: Break-even distances for wheat, peas and rapeseed produced in Canada and transported to Australia, France and Germany, compared to the travel distance to each destination country.
The break-even distances (blue, gray and orange bars) (mean ± standard error) represent the amount of ocean transport possible before the emissions from transportation break even with the difference in production plus land transportation emissions between regions. A negative break-even distance means that production emissions in the destination country are lower than in Canada. a,b, Results are presented with SOC change included in (a) and excluded from (b) the production emissions. Error bars (standard error) and significance tests were calculated using Monte Carlo simulation (1,000 iterations).
