UK case study as AC w contribution to GHG emissions

A

1st country to industrialise early C19 powered by coal so sig CO2 emissions increased 16 fold in course of century
emissions peaked 1971: since then, annual emissions dropped 1/3 due to shift to natural gas
since 1990, 2ary industry decreased, outsourcing instead (when emissions linked to imported goods included UKs national C footprint rises by 20%)
UK’s C emissions= 10th highest globally but falling over past 20 years (23% lower than 1990 to comfortably meet Kyoto)
3ary sector dominates economy: 80% of GDP and aerospace is 2nd largest national one

2013: China produced 29% of the total C from all human sources (20% for good shipped to Europe and USA)
didn’t sign Kyoto: emissions grew 2.5x 2000-2014
2006 overtook Usa as worlds largest emitter
2014 consumed as much coal as rest of world together
