the late David MacKay's "sustainable energy, without hot air" book about sustainable energy production versus energy consumption will help you roughly estimate your energy consumption. it's not the same thing as a carbon footprint, but it'll be more or less proportional. https://www.withouthotair.com/c18/page_103.shtml https://www.withouthotair.com/c18/page_103.shtml worth reading the book if you have the time and are interested. it's free online. From your list the one item that jumps out at me is 16 * 2.5 hour flights per year. i'd guestimate that accounts for 25% or more of your annual energy consumption, and 25% or more of your greenhouse gas emissions. probably roughly similar energy consumption footprint to eating 1 kg of meat / day. personally i think the main thing people with relatively* high-energy affluent lifestyles can do regarding reducing their personal carbon footprint is to have fewer children than they want to. it's not really a done thing to talk about this, maybe it will be in a decade or two. * relative in the global sense
