ENVIRON 157 Lecture Notes - Lecture 14: Carbon Cycle, Emission Intensity
Document Summary
Global fossil co2 emissions are dominated by electricity, heat, & energy (45%), industry (23%), & national transport (19%). International aviation and marine bunkers are 3. 5% & remaining sectors 10%. Coal co2 emissions are dominated by electricity, heat, and industry, with both showing significantly lower growth & even declines in the last few years. Oil co2 emissions are dominated by national transport with almost linear growth over five decades. Road transport is half the total growing at 1. 9% while national & international aviation is 8% growing at. Gas co2 emissions are dominated by electricity & heat, industry, and other commercial & residential sectors. Gas co2 emissions are growing rapidly in most countries and sectors, dominating growth in co2 emissions in recent years. Land-use change emissions are highly uncertain, with no clear trend in the last decade. Total global emissions: 42. 1 2. 8 gtco2 in 2018, 55% over 1990. Percentage land-use change: 39% in 1960, 14% averaged 2009 2018.
