2 Best Ways to Offset Your Carbon Emissions - Based on Personality!

"2 Best Ways to Offset Your Carbon Emissions - Based on Personality!" Article on sustainable travel blog Teja on the Horizon | Mangrove forest in Cairns, Australia

As you may be aware from indications elsewhere on this blog, I offset my carbon emissions with Terrapass. The reasons are simple: they are credible, audited, and I found their carbon footprint calculator easy to use. However, as my 40th birthday approached, I began thinking about offsetting my carbon emissions twice

If you haven't read it already, check out my article Two Simple First Steps to be an Effective Sustainable Traveller. I expand on both the recommended steps in this article. 

Why am I doubling my carbon offset now?

I suppose I could give various justifications for doing so. I could say that the second one covers my carbon footprint from the period of my life before I began offsetting. Or I could say that it covers the carbon emissions from non-energy consumption, which are more difficult to calculate, such as food and manufactured goods. 

2020 is also when I intend to write more specifically about carbon offsetting projects, to help aspiring sustainability advocates understand what they do (and don't do), and know what questions to ask. It felt synergistic to double down on my own commitment at the same time.

Whatever it is, it felt right and the timing felt right.

Who do I offset my carbon emissions with?

At first, I thought I would fulfil my pledge by simply doubling my calculated energy footprint at Terrapass, and then that would become my 2x emissions offset. It seemed pointless to do it any other way.

After all, any credible offset provider would have a carbon footprint calculator. How else would you know that you're offsetting 'enough', rather than just some arbitrary amount? But if so, what would be the point of filling in two calculators? 

However, as 2019 wore on, an alternative I never thought of popped up. The fuchsia branding of CHOOOSE began popping up all over my social media. CHOOOSE has the backing of the UN Framework Convention on Climate Change (UNFCCC), yet there's no carbon calculator to be seen. How is the accounting done? 

Curious, I checked them out. Their alternative was ingenious. So, when 2020 actually arrived, I ended up carbon offsetting with two different providers after all. Which one will suit you, kinda depends on your personality! 

The two ways to estimate and offset your carbon emissions

The difference between the way Terrapass calculates it, vs CHOOOSE, can be summed up in this very common scenario:

You are out for dinner with a bunch of other travellers from the hostel. At the end of the meal, the bill comes. How do you split the bill?

The more accurate way is for each person to calculate for their own food and drinks, plus some ratio of the shared stuff, taxes and tip. 

The faster way is for the whole bill to be split evenly across the number of people.

Are you terrible at keeping records?

In order to use any carbon footprint calculator, you have to have some record of the energy that you used, at least for transportation and around the home. 

Now, for someone who is organised (like moi), who have budget sheets and maintenance records and folders for tax receipts and bills, this isn't an issue at all. 

That said, I am quite aware that the majority of people are the opposite. 

If you are the kind of person who finds it difficult to be organised, but you still have the awesome heart to want to take responsibility for your carbon footprint, then a provider like CHOOOSE is the one I would recommend for you. (Actually, as of this article, CHOOOSE is the only provider that I know of that does it this way.) 

How did they get around the carbon calculator?

It's actually quite obvious, once they've done it.

Data already exists with folks at the UNFCCC about per capita emissions for various countries. Some countries have more precise data than others, of course. But roughly speaking, national scale data exists. You've probably seen the figures comparing different countries' climate change contribution, and per capita emissions statistics. 

Instead of having each person calculate their own emissions, CHOOOSE simply uses this existing data, and estimates a country-corrected carbon footprint for you. Basically, it assumes you are typical of your country, and calculates the emissions offset that an average person in your country would need to become carbon neutral. 

CHOOOSE does not have country-corrected amounts for everywhere, though. Certain countries, like in Europe or the USA, do get their own footprint values. But most other countries (including Malaysia) are just averaged out together, and are given a 'World Citizen' averaged footprint. 

Best of all, all of their projects carry Gold Standard verification, which makes them comparable to my existing offsets with Terrapass. So there's no conflict for me!

Does this method have shortcomings?

Sure. In our dinner example, one guy might have ordered a salad and another guy might have ordered the Wagyu steak. This approach means the total gets averaged out. 

But let's not get picky. If the simplicity of the method means that the obstacle of boring data review is removed for many, something is better than nothing.

My offset with CHOOOSE as a Malaysian is $3.50/month, totalling to $42 a year (offsetting ~11,000 lbs CO2e). This is via the default projects that fund replacement of fossil fuel use with renewable energy in developing countries.

There is a new, more expensive, option to achieve the same emissions offset. These are via projects that actively draw down past carbon emissions from the atmosphere to immobilise them.

CHOOOSE!

This is also a great interim option for those who want to do it the accurate way (see below), but haven't started keeping records yet.

Do you love keeping spreadsheets?

If you answered yes, then you would probably find using a carbon calculator perfectly fine - or even enjoyable! Two carbon calculators that I find sufficiently user-friendly are the ones at Terrapass.com and Carbonfootprint.com.

But why should I bother with a carbon calculator?

Are there good reasons to go through the extra trouble of using a carbon calculator? If you are reading this because you are a traveller at least some of the time, then I would say yes.

My total calculated energy footprint last year was 22,223 lbs CO2e. It cost me $110 to offset these emissions.

You may notice that it is double the averaged-out value assigned by CHOOOSE. Last year I made 1 trip to the Pacific, and 2 regional trips (Australia and India). It is immediately obvious from the photo below that these flight emissions are the reason for the discrepancy between the two methods. The average Malaysian does not typically make these many flights, nor so far.

The carbon footprint of flights is clear.

What are my other reasons for preferring a carbon calculator?

  1. I want to be able to compare my energy use between years. I want to see how much effect different lifestyle changes have on my carbon footprint. For example, if I take the train an extra day a week, does it really bring down a lot of emissions?
  2. I want to blog about it. So, I need data!

Are the various carbon calculators the same?

Essentially, the science behind carbon estimations have more or less settled, notwithstanding details such as radiative forcing. Databases have also been compiled by now from manufacturers and service providers.

Therefore, the algorithms underlying carbon calculators for different activities (e.g. flights), and the main assumptions (e.g. a certain vehicle model's fuel efficiency), are more or less consistent. Slight variations in calculations are negligible. The $ value of your corresponding offset will be determined more by the type of offset project, rather than more accuracy.

Therefore, the differences are really mainly in its user interface. Comparing between Terrapass and Carbonfootprint specifically, the most meaningful difference between them is that the latter offers calculation for secondary emissions. That's pretty much it.

(Secondary emissions are the carbon footprint of non-energy consumption, like food, electronics etc. I personally feel that these calculations vary too much to reliably estimate. Carbonfootprint estimates it by $ spend alone, which would require assuming many things about the products and services.)

How do you use a carbon calculator?

If you're slightly intimidated by carbon calculators, I'll walk you through it here.

Since I primarily offset with Terrapass, and since it doesn't really matter which calculator you use, I will be referring to Terrapass' calculator interface. But the data needs are going to be similar for other calculators.

Categories of energy use

Generally, you should expect to see the broad categories of our modern energy use in a carbon calculator:

  • Home energy - common sub-categories are electricity use, maybe also cooking gas or other gas uses.
  • Personal mobility - motorised transport like a car, motorbike, even boat!
  • Mass mobility - train, ferries, bus, etc.
  • Air travel.

This means that you could choose to start calculating your carbon footprint for just one or two categories to start with, if you're not ready to do all of it!

I'll now go into each category and tell you what kind of records you'll need to complete the sections.

Air travel

Offsetting air travel emissions

I start with air travel not just because it is the biggest footprint activity in the list, but also because it is the easiest to complete. You literally just need to remember where you took off, and where you landed. Seriously, that's it.

I remind myself of where I've been by looking at my calendar for the past year.

Personal vehicle emissions

This is also an easy category, if you're a good vehicle owner and get your car/truck/motorbike serviced at least annually. The reason is that the service invoice usually will have your mileage written on it. If you keep these in a folder, then you just need to take the difference (maybe pro-rate it if it wasn't exactly annual), and that's what you put into the calculator!

Otherwise you'd have to make a note of your vehicle mileage every time you do this, which to me is more of a hassle.

You also usually need to key in make and model, as well as year of the vehicle (newer vehicles are more fuel efficient). That said, from playing around with the calculator, getting the model wrong does make a noticeable difference, but getting the year wrong doesn't really.

Terrapass' calculator rounds to the nearest 2000 miles. Ever since I started trying to take the train more, I actually drive a lot less than this in a year. So, what I do is that I consider the remainder to cover the ad hoc ride shares, buses, and taxis that I take while travelling, and don't calculate these in the public transit section.

Public transit

Emissions from public transit is a bit trickier to fill in, because you don't really know the exact route. However, the good news is, accuracy matters less for this category because, comparatively speaking, the carbon footprint for public transport is so slight that even if you get it wrong a bit, the total emissions value won't change all that much.

Thankfully trains are no longer coal-fired...

I estimate my train commute to work, basically just by asking online maps for the distance. I compensate for route variations (sometimes I take different rail systems) by assuming a flat frequency of train use per week, even though this is more than I will really take due to holidays and travel.

Energy use in the home

Depending on how your home is set up, this can either be very easy, or a bit of a hassle.

A fully electrified house like mine, where even the stove is electric, only requires one kind of record: my electricity bills. All you need to do is total up the kWh consumption for the year, and that's it!

Easy record of electricity consumption

No, wait. There's one more thing. Terrapass will ask you for a US zip code (because it is US-based), whereas Carbonfootprint will ask for your country and then suggest a default multiplier. This is to reflect the power supply mix at your location. The carbon footprint of 200 kWh delivered via coal-fired power stations is not the same as 200kWh delivered via a combination of gas and solar.

Now, I don't live in the USA. So, the way I answer this question is by choosing a US state that has more or less similar power generation mix as Malaysia (by internet research). And I'm not sure if it matters to the algorithm, but I also consider similarity of climate. Florida more or less fits the bill - majority gas with some coal - so I just put in a Miami zip code.

If you have additional energy types at home, like cooking gas or heating oil, then this section gets a little trickier because you probably have to intentionally keep extra records. For example, how much cubic feet of gas? How many gallons of oil? So, you'll need to keep receipts for these purchases. Or maybe just do it for a year, and then just assume it stays the same if you haven't changed anything.

The third option that isn't really carbon offsetting

Ecosystem restoration

There is a third carbon capture option that a lot of environmental activists like. This is to donate money to NGOs that fund ecosystem restoration, like rainforests and mangroves. An example is the Rainforest Trust.

If we go back to our dinner analogy, this is like eating at one of those 'pay whatever you like' restaurants. It's based more on how much you appreciated the meal, rather than how much it cost to make it.

Are these projects helpful? Yes. From a biodiversity standpoint, from a coastal protection standpoint, even from a global warming standpoint, because indeed priority ecosystems like forests and mangroves also absorb carbon dioxide.

But are these projects carbon offsetting? No. Because there is no link between what you donated, and what is removed from the atmosphere.

Why does it matter?

Doesn't it ultimately remove greenhouse gases from the atmosphere anyway? Why do we need to correlate a purchase with CO2 equivalent (CO2e) removed?

The reason is because carbon offsetting is not truly about cancelling our personal emissions. It is about modifying our modern civilisation so that the impact of carbon emissions is considered in energy systems. It is to create a common means for this to happen, much like when banking was created.

So yes, for the big picture, support ecosystem restoration. Shift towards a plant-based diet. Take public transport. Bike more. But also offset your carbon emissions.

The elephant in the room for travellers

A question that is especially pertinent for travellers is whether travel itself has become unethical. Specifically, doing so by flying.

After all, you can see from my summary chart that flight emissions take the lion's share of my carbon footprint. Even if you take into account that my other emissions would increase if I'd stayed home, it would still not be anywhere near the flight emissions.

Here's where I'd like to refer to Step 2 in my article Two Simple First Steps to be an Effective Sustainable Traveller, and the effect of intention.

How often do I travel?

A lot of my friends assume that because I have a travel blog, and post regularly on my associated social media profiles, I must travel a lot. Here's my carbon footprint for two years ago, 2018:

Only 1 fewer Pacific trip nearly halved the flight emissions.

I only took two trips that year, 1 trip to the Pacific and 1 domestic. The flight emissions are almost entirely due to the Pacific trip. And the Pacific, of course, is a region very difficult to visit unless you fly.

Yet, despite taking only two trips in 2018, I still have a writing schedule that easily extends into 2021. If I take into consideration my 2019 trips, it goes further. How can this be?

You see, after my odyssey to Nepal, and after I finished writing about it, I discovered unexpected things. Knowing that I would be blogging about it, I paid more attention. Because I paid more attention, my travel enjoyment improved, and my habits became more sustainable. I tried more things, and so I had more stories.

And because I have so many stories to tell, I find that I don't crave to travel as much. And because the travel changed me, and because I now don't crave travel as much, I can give back to projects at home, like training to be an EcoDiver this year.

A small thing, intention. Yet how powerful it is, when repeated.

What is your travel intention?

We fly for many reasons. Some of them are very trivial. Take a flight out on the weekends just for a night out on the town, or a private jet to a summit.

But some of us have international businesses. Some migrate to find work. Some have families separated by vast distances. And people in some places can only reach the rest of us across oceans.

Perhaps for those who previously lacked the awareness to feel shame, the flight shame movement is raising mass awareness to think about the purpose of their air travel. However, this is an introspection that is largely only relevant to the privileged 1% of humanity.

By contrast, air travel forms crucial links for mountainous or archipelago regions, often the most sustainable means of transport. Substituting air travel with rail in some regions would entail opening up forest land. For other regions, the alternative to air travel are the even more polluting passenger ships.

Travel does contribute a lot of flight emissions. But travellers create connections between people. And those connections are crucial because our pressing problems today are global in reach.

So I think, in general, flight intention is more useful in the long run, than flight shame. And I repeat my two simple steps for a sustainable traveller: Reflect on your intention, and offset your carbon emissions.
