A decarbonized world is by now irreversible, irrefutable and we are going to do it, because frankly we don't have any other option. - Christiana Figueres, executive secretary of the U.N.'s Framework Convention on Climate Change

Decarbonization is a word you're likely going to be hearing a lot more of... in the years and decades to come. It means cutting out the carbon -- on a massive scale: Doing away with fossil fuels and embracing renewable energy sources, in order to cut planet-warming emissions to a net zero.

And "decarbonization" isn't just a word Christiana Figueres is using these days. A growing chorus of scientific experts, world leaders, and even World Bank officials agree, decarbonization is the only way to keep global warming to an internationally agreed limit of 2 degrees Celsius.

"Decarbonization" was definitely a buzzword as the G7 Summit wrapped yesterday in Germany with world leaders -- including Prime Minister Stephen Harper -- setting a goal of a fossil-fuel free world before the end of the century. German Chancellor Angela Merkel had hoped to convince her counterparts to agree to a low-carbon economy by 2050, but Canada and Japan reportedly resisted. In the end, the G7 pledged to go carbon-free by 2100.

The word decarbonization isn't likely to be warmly embraced in Alberta's oil patch. However, Bryson Brown says a transition away from fossil fuels doesn't have to be as painful for the province -- or the country -- as some people might think.

We did contact the Prime Minister's Office to see if someone from the government was able to talk about this but no one was available.
