The Umweltbundesamt (sort of German EPA, I figure) recently released a new study on the "Ecologisation of online shopping" - which obviously is in German. Anyway, core findings are that individual shopping using your own car is the worst (CO2-wise) with 600 to 1100 g CO2 (for a 5 km ride to the store), while delivery is better due to optimized ...

Have they considered post-mix soda/coke served in a glass? There's a significant up-front investment but in the long term it should pay for itself, but only if they sell a fair bit. I don't know how common this is in Italy, but it's the norm for pubs here in the UK. Pubs here do stock cans/bottles of less common soft drinks, as well as juices, but this would ...

I'm not sure what P2P protocol was used and if results for BitTorrent would be the same, but in this study they calculated a decrease of 24-48% in the system-wide carbon footprint of online video streaming when using P2P compared to Content Delivery Networks. The paper describes that this is mainly because of selecting close by peers to share content from ...

Though it does not make the situation easier, population is not the elephant in the room when it comes to CO2 emissions: we might afford 10 billion with low lifestyles, but the habits of the less than 1 billion Western inhabitants on the planet already make the situation unmanageable. This is the elephant in the room. 10% of the population drives 50% of the ...

According to figures from Alko (the Finnish state-owned alcohol distributing organisation), producing packaging for a 1,5 L (~4 gallons) wine pouch creates 96 g (~3,3 ounces) of CO2e/L whereas a 0,75 L (~2 gallons) traditional glass bottle hits almost seven times that figure at 675 g (~23,8 ounces) of CO2e/L. Source Additionally, the answer depends on your ...

An individual environmental footprint is not strictly measurable in a physical scientific sense, unless you live a life which is completely detached from others. The normal human existence is so deeply entwined with the lives of others that you cannot measure the precise impact of your own actions. There are so many different ways in which we (speaking as a ...

Many population growth estimates actually suggest that the growth will slow down in the future. The main arguments are that the global fertility rate is decreasing and that the median age of the world population is going up. Reference: World population growth is expected to nearly stop by 2100

According to a report by the US Climate Change Program "virtually all the glaciers in the mid-latitudes are in a state of negative mass balance and are retreating" (2008). By how much each year and specifically in the last 40 years, is presented in the following study as being −5.2 ± 2.2 Gt¹ (metric gigatonnes) per year during the full 1975–2016 ...

Look at multi-use glass bins (yoghurt, milk, etc.): They have to be cleaned very well, that means a lot of energy and chemical pressure. Transportation even for short distances count, you can´t put this away. And bins always need a brand new cap (because old ones rust and the plastic layer inside can´t be cleaned sufficiently). And last but not least: Even a ...

The benefits are related to protecting the various household appliances that are fed by your water supply. Hard water leads to heavy limescale deposits which can damage your heating system. The most sensitive item would be the boiler for hot water and central heating. This leads to many people believing that there is an environmental benefit to softening ...

According to this article in Environmental Science & Technology (2020) the least GHG intensive process would be online shopping with fulfillment via physical store delivery: We found that shopping via bricks and clicks (click and fulfillment via physical store delivery) most likely decreases the GHG footprints when substituting traditional shopping, ...

It's possible to make a composting toilet out of very simple parts, and those can work very well. But you need a supply of sawdust, woodchips or some other dry organic material. My brief experiment with dried grass was not successful although I've read that it can work. There are lots of places on the web where people document their experiments: The problem ...
