Aaron Jones | Personal Carbon Statement

Carbon Statement

I acknowledge that the scientific consensus regarding the existence of climate change and the substantial contribution the human contribution is now making to this via our greenhouse gas emissions. Furthermore, I recognize the scale of the climate emergency posed by our current emissions levels and our individual responsibility to mitigate the impact of climate change. I also recognize the need for institutional changes and our responsibility as citizens and scientists to highlight the issue to our elected representatives.

Key Commitments:

  • To purchase renewable electricity to heat my home (saves approximately 0.9 tonnes per year).
  • Travel by either walking, bicycle or public transport wherever it is financially viable.
  • Carbon offset all flights from May 2019 onwards.
  • Advocate for climate action consistent with the science.
  • To eat a low meat diet.

Annual Emissions Estimate

Pie diagram with 2018 carbon emmissions estimate breakdown

My work and lifestyle choices in a typical year (2018) result in around 3.9 tonnes of CO2 being released into the atmosphere. The largest offenders are:

  1. Car Travel: 1.7 tonnes per year. I take the total household car mileage divided by the number of occupants.
  2. Flights: 1.2 tonnes per year.
  3. Food choices: 0.88 tonnes per year.
  4. Clothes textiles and shoes: 0.1 tonnes per year
  5. Books: 0.01 tonnes per year.

These numbers were calculated with the carbon footprint calculator, however, flights were calculated separately.

Lifetime Flight Estimate

The graph shows an estimate of my lifetime carbon footprint from flying, inspired by Sean Leavey's similar plot and script.

Before 2010, in most years I did not fly and so there are large flat regions in the graph. The large spike in 2016 is due to a single holiday to China and Thailand. 2018 I took the train to an international conference which had a noticeable effect of my emissions for that year. Most of my emissions are due to personal travel, I have only taken 4 flights for business reasons.

Notes: The early flights are rough guesses because then routes have changed. The CO2 emissions are taken from GoClimateNeutral API.
