A new analysis from Carbon Brief, however, suggests that this concern may be overblown. Specifically, the analysis suggests that emissions are now 38% lower than they were in 1990—and while it’s true to say that emissions were largely ‘offset’ by a rise in imports until the mid 2000s, that no longer holds true as embodied emissions in imports have also been falling since 2007. This is extremely positive news. And Carbon Brief credits a mix of much cleaner renewable energy generation—as well as a fall in overall energy demand from industry and private citizens alike—for bringing down emissions so dramatically.
