Having recently come back from a short, long-distance trip halfway around the world in the name of sustainability science – and having blasted a vast amount of carbon into the air in the process – I couldn’t help to think, yet again, about the perpetual challenge of “walking the talk” in sustainability science. But how does one “walk the talk”? The following are some suggestions for how to think through this.
- If it’s work-related travel, carefully weigh the sustainability costs and sustainability benefits. Frankly, a lot of work-related travel is not needed. We have a culture of workshops and meetings, and a culture of attending lots of these even if they are far away. Travel is cheap, workshop papers (i.e. discussion blabla papers) sell well, and have become a business in their own right. Personally, I believe in (i) prioritizing fieldwork related air travel over workshop air travel, (ii) prioritizing close travel for workshops/conferences over far trips, and (iii) thinking through how much travel you are willing to do in a given year.
- With respect to work travel, question the difference between what is necessary versus expected versus something you simply feel like. It’s too easy to say “I was invited and so I went”. In a culture where we all travel around without a second thought on whether that is good or necessary, just travelling a lot because everyone else is doing it is a very poor argument. So, as a minimum, be honest with yourself about (i) what is necessary, (ii) what is expected of you, and by whom, and (iii) what is simply your personal preference. Things you classify as necessary, well, I guess they can’t be changed easily. For things you classify as expected you can think about whose expectations these are, and whether you need to meet these expectations. And regarding third, frankly, that might be a fine reason at times, but from a sustainability perspective you should be aware that a preference for personal gluttony is also what’s destroying the planet. So probably best to remain a bit critical with oneself on this last point!
- Is there a way to get there without flying? Air travel is fast, and cheap (because it does not account for externalities). But it’s not the only way to get around. For example, many trips within Europe are possible by train if you think about it a little bit in advance. Night trains exist to some places, too.
- Once you decide to fly somewhere, consider offsetting your carbon impact. Most likely, your workplace – even if it’s a sustainability department – won’t have an offsetting scheme (do any?? I’d be interested!). Still, you can consider offsetting your personal and work-related carbon emissions. People who fly a lot also tend to earn a lot, making this not as big a deal as it may sound. Obviously, in science, your ability to offset depends on your salary and/or career level.
- Beyond travel, differentiate between big-ticket items versus little things in your life. Little actions can be good because you can do many little things. But changing a few big things in meaningful ways may achieve even more in terms of sustainability. Big changes are, for example, to live somewhere where you can ride a bike to work, rather than drive every day. Or to cut down the amount of animal protein in your diet, or obtain your food more locally. Little things like turning off light bulbs are fine … But just leaving your car at home one day (when you normally drive) is like a lot, a lot of lightbulbs!
- Recognise that you’re part of a “system”, and work on personal change as well as systemic change. While some sustainability scientists do too little (in my, in this case, not-so-humble opinion) to walk the talk, others beat themselves up for not being perfect footprint-free creatures. I think it’s important we recognize that it’s both a personal and systemic issue. If you live in North America or Australia, it’s nearly impossible to have a lifestyle that is fully sustainable. Most likely, most things from the food you eat to the transportation systems you use, to the infrastructure you support through your taxes are unsustainable. That is why it’s worthwhile to think about what you can do, and do that – while at the same time working on systemic changes so that living more sustainably becomes mainstream. That is, the institutional and socio-cultural context we live in will ultimately need to change, but that won’t happen overnight.
Comments on how you think about “walking the talk” are, as always, most welcome!
