You’re in the market for a new backpacking stove, and as you consider your options—canister stoves vs. liquid fuel stoves—you’ll probably factor in packability, weight, boil times and cooking versatility. But, if reducing your impact and selecting an eco-friendly camp stove also plays into your gear-buying decisions, the choice is clear.
Of the two main camp stove fuel types, liquid fuel stoves are by far the eco-friendlier option.
Reusable bottles, less waste
Liquid fuel camp stoves (often called white gas backpacking stoves), like MSR’s Dragonfly and WhisperLite stoves, beat out canister stoves as the eco-friendlier fuel source for one key reason: Liquid fuel bottles are reusable. Instead of throwing away several metal canisters (or recycling MSR’s IsoPro canisters) after a backpacking trip, you can simply refill a liquid fuel bottle for your next trip.
By reusing that same bottle time and time again, you maximize the value and life of that resource, and eliminate all that empty canister waste.
Exact fuel amounts, every drop used
Wasting less in turn allows us to consume less. Topping off your liquid fuel bottle before each trip means you’ll make use of any fuel left over from your last adventure. Because of this, you likely won’t need to purchase new fuel as often. In contrast, leftover half-used isobutane canisters can pile up in our gear bin. If we wish to start our next trip with a full canister, we must purchase a brand-new one. After our trip, that canister might also be tossed, half-used, onto the pile.
Of course, canister stoves offer important advantages in the outdoors—they’re light, compact and maintenance-free. Liquid fuel stoves, including multi-fuel camp stoves, generally weigh a bit more than their canister counterparts, but they offer superior cooking versatility and cold-weather performance. And those few extra grams may be worth it to you when you think of all the waste you’re reducing.
