Grocery Delivery Lowers Carbon Dioxide Emissions Over Individual Trips 417
vinces99 writes "Those trips to the store can take a chunk out of your day and put more carbon dioxide into the atmosphere. But now University of Washington engineers have found that using a grocery delivery service can cut carbon dioxide emissions by at least half when compared with individual household trips to the store. Trucks filled to capacity that deliver to customers clustered in neighborhoods produced the most savings in carbon dioxide emissions, but there are even benefits with delivery to rural areas."

I suspect the European corner shop system is less energy-efficient than a supermarket. Large buildings cost less to heat, light, and refrigerate per customer, and because a large market is able to average out irregular customer behavior over a larger number of customers, I bet they need fewer employees per customer and throw out less expired food per customer, both of which mean huge indirect energy savings.

It really comes down to how our communities are designed. The US has worked really hard to build communities that are difficult to live your life without a car.

The same with excercise. It makes the problem worse because you need more food if you don't sit on your butt all day.
BTW, the biggest engine you can get in a 4x4 for a full-size family is 6 L. This is for the 2013 GMC Savana Passenger Van. You can o

That bike looks like it could barely handle more than a few bags of groceries. When you're buying for a family and not just yourself, that is pitifully small.

the manufacturer says : 80Kg max in the front compartment. I have seen people drive it with 2 kids AND groceries in it.

That sounds like a much bigger problem with American drivers than with cyclists.
What kind of person feels obligated to harass someone else because they don't agree with the way they choose to get around or live their lives?

exactly the point he was making. buy smaller quantities more often and you get to enjoy something known in the rest of the world as fresh fruit, fresh vegetables and fresh bread. also, what's wrong with drinking tap water? (hence the title - America-centric much?)

ok, maybe not for a family, but for an individual student, this is definately feasible. I did it myself when I was studying in Palo Alto, and it wasn't even a proper backpack. Just beware of not packing too tightly if you've bought eggs...

I've found that if you murder people, they stop emitting CO2 almost entirely. So really, serial killers are the best environmentalists.
If they don't dispose carefully though they can increase methane emissions, which is even worse. Seriously these serial killers should investigate the environmental impacts of acid baths, cremation, etc. My gut feeling says that using the bodies for livestock feed or eating them yourself is the most environmentally sound approach

True on a world-wide scale. However, in the US, 32% of CO2 emissions is from transportation [epa.gov]. It's harder to find numbers on motor vehicles in the US, but the closest I get within 3 minutes of Google is almost a quarter of annual US emissions of carbon dioxide (CO2). (...) The US transportation sector emits more CO2 than all but three other countries' emissions from all sources combined. [ucsusa.org]
Unfortunately, it looks like there is no simple way to reduce CO2

If you want to be even more efficient how about you do a "Foxconn" - live, eat, etc at your workplace and do away with most grocery trips completely.
The thing is, if you want to do this without sacrificing quality of life (which the actual Foxconn employees certainly do), you need to put a *lot* of stuff on the workplace's campus. Single-family housing, apartments, medical facilities, food, movie theaters, playgrounds, legal offices, accountants, education, police ... all this stuff takes up space, so your
