Sourced, numbers-first writing on carbon footprints, emissions, and the math behind climate decisions.https://www.co2mate.app/enhttps://www.co2mate.app/blog/average-carbon-footprint-by-country/https://www.co2mate.app/blog/average-carbon-footprint-by-country/From under 2 tonnes to over 30, per-person CO₂ varies enormously by country. A sourced tour of the numbers, the territorial-versus-consumption catch, and what 'average' should mean to you.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-a-beef-burger/https://www.co2mate.app/blog/carbon-footprint-of-a-beef-burger/A single beef burger carries roughly 3–6 kg of CO₂e — more than ten times a bean burger. Here's the sourced breakdown, where the emissions actually come from, and how the swaps compare.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-bitcoin/https://www.co2mate.app/blog/carbon-footprint-of-bitcoin/Bitcoin's network uses about as much electricity as a mid-size country. But 'per transaction' numbers mislead, and Ethereum cut its energy ~99.9% in 2022. The sourced, careful version.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-clothing/https://www.co2mate.app/blog/carbon-footprint-of-clothing/A pair of jeans can carry 20–30 kg of CO₂e over its life; a cotton t-shirt 2–7 kg. Here's where the emissions hide — and why wearing things longer beats almost every other fix.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-coffee/https://www.co2mate.app/blog/carbon-footprint-of-coffee/A black coffee is about 0.05 kg CO₂e; a large latte can be five times that — and the difference is almost entirely the milk. The sourced numbers, and the one swap that matters.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-flying/https://www.co2mate.app/blog/carbon-footprint-of-flying/One long-haul return flight can outweigh a year of careful choices elsewhere. Here's what a flight really costs in CO₂ — including the contrail effect most calculators quietly ignore.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-driving/https://www.co2mate.app/blog/carbon-footprint-of-driving/An average petrol car emits two to three tonnes of CO₂ in a typical year. Here's the per-kilometre math, how electric really compares on a real grid, and what changes the number most.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-food/https://www.co2mate.app/blog/carbon-footprint-of-food/The carbon footprint of food swings more than tenfold depending on what's on the plate. The data is unusually clear about where it concentrates — and it isn't 'local versus imported'.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-home-heating/https://www.co2mate.app/blog/carbon-footprint-of-home-heating/Heating a home with a gas boiler can emit 2–4+ tonnes of CO₂ a year — often the single biggest line in a cold-climate footprint. Here's the math, and how a heat pump changes it.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/carbon-footprint-of-streaming-and-ai/https://www.co2mate.app/blog/carbon-footprint-of-streaming-and-ai/Your digital life has a real carbon cost, but it's routinely exaggerated. Here are the sourced per-use numbers for streaming, email, and an AI query — and where the genuine concern actually lies.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/do-carbon-offsets-work/https://www.co2mate.app/blog/do-carbon-offsets-work/Buying an offset feels like closing the loop. The evidence says most voluntary credits don't deliver the cuts they sell. A sober look at additionality, permanence, and what to do instead.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/electric-vs-petrol-car-break-even/https://www.co2mate.app/blog/electric-vs-petrol-car-break-even/An electric car starts with a bigger carbon debt from its battery, then pays it back in roughly one to two years of driving. Here's the sourced break-even math — and how the grid changes it.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/flying-vs-train-vs-driving/https://www.co2mate.app/blog/flying-vs-train-vs-driving/Per passenger-kilometre, the train is typically 5–10× lower than flying or driving alone. Here's the sourced comparison — and the occupancy and distance caveats that flip it.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/is-recycling-worth-it/https://www.co2mate.app/blog/is-recycling-worth-it/Recycling genuinely cuts emissions — recycling aluminium saves about 95% of the energy of making it new — but it's the smallest of the three Rs. A sourced look at what it does and doesn't fix.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/paper-vs-plastic-bags/https://www.co2mate.app/blog/paper-vs-plastic-bags/On climate alone, a thin plastic bag often beats a paper one — paper takes more energy to make. But reuse changes everything. The sourced answer, and why the question is the wrong one.Tue, 09 Jun 2026 00:00:00 GMThttps://www.co2mate.app/blog/what-is-a-carbon-footprint/https://www.co2mate.app/blog/what-is-a-carbon-footprint/A carbon footprint is the greenhouse gas your year adds to the atmosphere, in one number. Here's how it's measured, what the global average really is, and which choices actually move it.Tue, 09 Jun 2026 00:00:00 GMT
