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.
- 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
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:
- Car Travel: 1.7 tonnes per year. I take the total household car mileage divided by the number of occupants.
- Flights: 1.2 tonnes per year.
- Food choices: 0.88 tonnes per year.
- Clothes textiles and shoes: 0.1 tonnes per year
- Books: 0.01 tonnes per year.
These numbers were calculated with the carbon footprint calculator, however, flights were calculated separately.
Lifetime Flight Estimate
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.
