What are the energy use and emissions projections for 2021?

The IEA Global Energy Review 2021 (April 2021) provides an outlook for 2021 energy use and emissions. Energy use to go up:

Global energy demand is set to increase by 4.6% in 2021, more than offsetting the 4% contraction in 2020 and pushing demand 0.5% above 2019 levels. Almost 70% of the projected increase in global energy demand is in emerging markets and developing economies, where demand is set to rise to 3.4% above 2019 levels. Energy use in advanced economies is on course to be 3% below pre-Covid levels.

CO2 to go up:

Demand for all fossil fuels is set to grow significantly in 2021. Coal demand alone is projected to increase by 60% more than all renewables combined, underpinning a rise in emissions of almost 5%, or 1 500 Mt. This expected increase would reverse 80% of the drop in 2020, with emissions ending up just 1.2% (or 400 Mt) below 2019 emissions levels.

Lots of graphs in this report. The data doesn’t seem to be available with the report but the IEA has a data page where you may be able to find data you’d like.
