Global Carbon Budget 2019Fossil CO2 emissions grow more slowly... but do not yet decline
Natural gas and oil now drive global emissions growth
�e rise in atmospheric CO2 causes climate change
CoalOilGas Land
Emissions growth in the last 10 years was slower than in the previous 10 years because of slower growth of coal
CO2emissions
need to decline rapidly to net-zero
around mid-century to pursue the
Paris Agreement 1.5°C goal

�e global carbon cycle 2009-2018
Continued support for low-carbon technologies needs to be combined with policies that phase out fossil fuels.
Deforestation �res in 2019 drive emissions up on land
