Flashcards in Case Study: UK GHG Emissions Deck (19)
CO2 emissions at 2,252,000 tonnes. Pre-industrial so agriculture and manufacture didn't use machinery that was powered by fossil fuels.
Coal-powered industrialisation took off. By 1850 CO2 emissions were at 33,468,000 tonnes.
Coal production peaked at 137 million tonnes.
Occasional dips in emissions due to falls in GDP and economic activity e.g miner's strikes in 1921 and 1980s, leading to less coal production.
CO2 emissions peak.
Shift away from coal as the primary fuel for electricity generation towards cheaper natural gas.
Timeline: 1980s + 1990s
Development of nuclear power stations and renewable resources.
Timeline: 2011 onwards
Further drop in emissions due to energy conservation through energy efficient homes/factories, and due to international obligations to reduce emissions e.g. Kyoto.
Carbon emissions fell by a record 9% from the previous year. This may be due to a mild winter leading to a fall in demand for heating. Coal consumption was the lowest since 1850. 2 major coal power stations decommissioned and the largest (Drax, N. Yorkshire) switched to biomass. 15% of electricity generation came from renewables.
