The most effective carbon sinks are peatlands. the approx. 3 Mio. km2 in Canada sequester 370 Million Tonnes of Carbon a year.
Canada alone emitted 679 Million Tonnes in 2022, with a population of just about 30 Million people.
There is simply no capacity to offset the emissions we have, even with radical land transformation. The only way is to drastically cut emissions and cut them fast.
