Forestry carbon offsets grapple with image problem

Carbon offsets and emissions trading evolved out of the 1997 Kyoto Protocol as a mechanism that could be used by industries that either couldn’t reduce their emissions – airlines are a prime example – or found it too expensive.

Since the battery-powered electric passenger plane does not exist, about the only mechanism available is an offset, which a carbon offset broker sells to individuals or companies that want to neutralize their flight emissions, and buys credits in a project somewhere that is reducing greenhouse gases.
