Approximately 18 months ago 4RG reviewed web-based carbon offsets for airline passengers. These offsets enable a passenger to “purchase” financial assistance for projects to reduce GreenHouse gas emissions equivalent to each passengers’s share of carbon emissions from the aircraft during the trip. In this way a passenger’s air flight has a net zero carbon footprint.
As we are about to leave on another international air trip (the Far East via Bombay) an update on carbon offsets is timely.
Since May 2007 the Air Canada Website has a page that allows purchase of carbon offsets. As of September 2010 Air Canada passengers had paid $263, 042 for these offsets, or nearly $90,000 per year. Approximately three years later the payments had risen to $306,866, an increase of approximately $13,000 per year. Clearly offsets are declining in popularity.
