Frequently Asked Questions

Why should I care?

Greenhouse gases (GHG) emitted by the aviation industry are a major global contributor to climate change [5]. Not only do jets release large quantities of these GHG, but they release them higher in the atmosphere which amplifies their effect [6].

Most governments worldwide acknowledge the harmful effects of aviation but have yet to impose standards on emissions as they do with other forms of transportation like automobiles and watercraft (the US is expected to do so in 2017 [7]). More importantly, most governments worldwide have yet to pass legislation that forces airlines to account for the present and future damage each metric ton of GHG present in the atmosphere causes directly to people.

In effect, we are not paying the true cost of our travel when we buy an airline ticket. Having the integrity to purchase carbon credits offsets these harmful emissions and neutralizes our impact over time. 

How can I know my investment will be used effectively?

That's a great question - why not just use your money to buy some seeds and plant trees yourself? There are several advantages of contributing money to an effective organization. First, they can make use of economies of scale to make your money go further (eg. buying more seeds at a cheaper price) because they receive contributions from around the world. Second, they have the staff to ensure your investment is well tended and has a long life span.

We at HC3 have looked over dozens of foundations to hand pick the one that has a solid reputation, a logical and proven strategy for investing in projects, and understands the nuances and pitfalls of carbon credits. You can read more about the intricacies of carbon credits on Conservation International's excellent blog post.

What are other foundations I can contribute to?

If you're not happy with the organization we've chosen, there are handfuls of others to look through (we recommend reading the blog post linked in the previous question). Here are some examples:

Are carbon offsets an effective long term strategy to mitigate climate change?

No, absolutely not. Carbon offsets are an effective component of a risk mitigation strategy only in conjunction with a "low-impact" lifestyle. You should continue using bikes for transportation, composting, buying local food, minimizing AC/heater use, and avoiding air travel whenever possible.

Carbon offsets have been criticized as a tool for wealthy travelers to indulge guilt-free and thus increasing the frequency of their emissions. That's not the intended purpose of these services and should never be used as an excuse - only travel when necessary.

Where can I go to learn more?

To learn more about the negative effects of airline travel, Wikipedia is a great source.

To learn more about climate change in general, we've released a blog post about fantastic, relevant resources.
