Important question! My main concern is to combat climate change with all my energy. Whilst it is still hard to leave all routines behind, I try to challenge myself on every action I take. - I changed my employer in December to work on renewable energy topics. It gained me 5000€/a, so win/win. - I switched my power supplier to eco 5 years ago. Probably 50€ per year. It is important to choose a real eco-friendly tariff. Some are only labeled as environmentally friendly. - I am donating to greenpeace and other environmental ngos (as well as planting trees). ~400€ per year. - I stopped using a car a few years ago. I am substituting it by public transport and/or my bike. Occasionally, I still rent a car, however much less. I would say, it costs a lot of time sometimes but it is hard to figure out the number. All things considered, I am certainly saving money. - I am only buying organic food and especially meat with no compromise. It probably costs me 50-100€ per month compared to shopping in a discounter market. Since the meat is quite expensive, I reduced consumption drastically (but not only for economic reasons). - I am not taking airplanes anymore to go on holiday. This costs a lot of time. My last travel to Greece took 3 days instead of 3 hours. - I have reduced shopping and online shopping to a minimum. It just saves money and time as well. - I have put stickers for the past global climate strike, it cost me a few hours. Participating some hours as well. - I am always bringing my tupperware for picking-up food (except pizza), no compromise, no one-way packaging. This is not really combatting climate change but it helps against environmental pollution. - Countless hours of debating with people :-D Also, many little things which I forgot to/can't mention. I think everybody should do as much as he or she can, get used to it, do more, get used to it, do more, etc. :)
