Health authorities overall in B.C. paid a little over $5 million in 2015 in carbon offsets. School districts paid $3.5 million.
Hardest hit are districts like Surrey, where growing enrolment means more portables, which are not energy efficient.
The Surrey school district was forced to pay $388,750 in carbon offsets in 2015. Vancouver school district paid $361,950.
In 2015, the B.C. government bought $7.2 million worth of credits, the bulk of which went to forestry conservation projects, which are controversial. In 2015, an improved forestry management project for the north and central cost region of the Great Bear Rain Forest received $1 million.
The Haida Gwaii area of the Great Bear Rain Forest received $3.1 million. The Cheakamus Community Forest in Whistler received $297,458.
Dowlatabadi thinks investing in carbon sinks, like forestry conservation, is the least valuable investment, when it comes to getting actual, measurable carbon reductions. For one thing, the actual carbon reduction that results from simply letting trees grow is difficult to measure, and the investment can be wiped with a single forest fire or pest infestation.
