Last year, humans on the planet Earth would appear to have set a new world record for fossil fuel consumption.
Each year in June two very important reports are released that provide a comprehensive view of the global energy markets. The highlight of the recently released Renewables 2016 Global Status Report was that the world’s renewable energy production has never been higher. But the biggest takeaway from this year’s BP Statistical Review, released Wednesday, may be that the world’s fossil fuel consumption has also never been higher.
While global coal consumption did decline by 1% in 2015, the world set new consumption records for petroleum and natural gas. The net impact was a total increase in the world’s fossil fuel consumption of about 0.6%. That may not seem like much, but the net increase in fossil fuel consumption — the equivalent of 127 million metric tons of petroleum — was 2.6 times the overall increase in the consumption of renewables (48 million metric tons of oil equivalent).
How much of that year-over-year increase in the equivalent amount of petroleum consumed, representing the planet's increase in total fossil fuel consumption by humans, do you suppose could have ended up in the Earth's atmosphere?
Doing the math, we know that for every 1 kilogram of petroleum that is burned, approximately 3.15 kilograms of carbon dioxide is generated. [We say "approximately" because this figure assumes 100% complete combustion.]
Therefore, if we assume that all 127 million additional equivalent metric tonnes of petroleum consumed in 2015 were fully combusted, it would generate a little over 400 million metric tonnes of carbon dioxide, which marks the maximum amount of additional CO2 that could have been emitted into the air above the level produced by all fossil fuel consumption through human activities in 2014.
That's 0.4 billion metric tonnes, which is the number we need to plug into our tool for calculating the atmospheric concentration of CO2 given the number of billions of metric tonnes of carbon dioxide emissions.

Compared to 2014, the concentration of carbon dioxide in the Earth's atmosphere has been increased by a maximum of 0.051 parts per million, given the incremental increase in human fossil fuel consumption by people during 2015.
By comparison, the 2015 Indonesia wildfire had well over four times the impact, increasing atmospheric CO2 by at least 0.224 parts per million.
And if we consider the 1997 Indonesia wildfires, which increased the concentration of atmospheric carbon dioxided by approximately 0.54 parts per million in 1997 and 1998, that event had nearly 10 times the impact.
Please keep these values and dates in mind when considering the following chart, which shows the trailing 12 month average of the year-over-year change in the amount of atmospheric carbon dioxide in the Earth's atmosphere.
Looking over the atmospheric CO2 data, we expect the current upswing in the rate at which the level of carbon dioxide in the Earth's atmosphere is changing to continue in the near term, as the data likely doesn't yet reflect the impact of the Fort McMurray wildfire.
