What are carbon offsets?

Many of your daily activities emit greenhouse gases, which contribute to climate change. This is particularly problematic if you drive or fly a lot. Cool Effect estimates that an average American is responsible for 16.6 tons of carbon each year. (Other estimates are even higher.)

Perhaps, you can fly less or buy an electric car, but completely removing your emissions is not an option. Carbon offsets are an affordable way of compensating for your environmental impact (though second best after reducing your emissions.)

A carbon offset is a reduction of carbon emissions, measured in metric tons. This is how offsets work:

  • Certain carbon-reducing projects, like planting a coastal mangrove forest in Myanmar, are issued carbon credits by a carbon standard. (In this example, mangrove trees (pictured) store carbon and prevent coastal erosion)
  • An offset reseller like Cool Effect or Terrapass buys offsets from the project and sells them to you, charging a markup or a flat fee
  • By buying offsets, you support these projects and reduce the environmental impact of your own emissions

Compare carbon offset prices

Although voluntary carbon offsets were initially bought by big companies, over ten U.S. providers now sell them to individuals.

Most of these companies also provide handy calculators that let you add up your emissions. Although most providers sell all-purpose offsets, some specialize in travel or even Bitcoin. (Mining Bitcoin is notoriously energy-intensive.) We have compared prices from the top ten providers of offsets to Americans:

Pricing data is accurate on 9/3/2021

These prices are for individuals, not businesses, and cover activities from flying to driving and, generally, living. Some companies also offer discounts if you subscribe or buy in bulk.

We have found the Switzerland-based myClimate to be the most expensive and Cool Effect to be the cheapest.

Note: although it’s easy to compare prices per ton, each company supports different carbon reduction projects, and some are pricier than others. The impactful projects can be the most expensive. (For example, paying someone not to cut down a forest is cheaper than planting a new forest. Yet most would prefer to pay to plant a new forest.)

So the price comparison is not apples-to-apples, and we recommend checking that you like the projects each offset provider supports instead of just buying the cheapest offset available.

Companies selling individual carbon offsets

Carbon Credit Capital

Founded in 2006, Carbon Credit Capital lets you buy individual offsets and flight offsets. They are a certified B Corp and a member of 1% for the Planet. A ton of carbon currently costs $14.

Carbonfund

Carbonfund is a nonprofit that sells offsets for general lifestyle, vehicles, air travel, and homes. 95% of the price you pay for offsets goes to support carbon-reducing projects. You can also gift offsets or pay to plant trees.

Clear

Clear offers personal carbon offsets with a focus on travel, including activities like skydiving and balloon flights. You also have the option to make your activities carbon-negative rather than just carbon-neutral. (Apparently, five hours of balloon flight emit 1.09 tons of CO2).

Cool Effect

Cool Effect is a carbon offset nonprofit that started by installing clean-burning cookstoves in Honduras in 1998 but now specializes in carbon offsets for travel. Roughly 90% of the price you pay for offsets goes to carbon-reducing projects.

MOSS

Brazilian company MOSS sells offsets supporting reforestation projects in the Brazilian rainforest. Although they let you offset flights (with pricing in Brazilian reals), MOSS’s most interesting offer is the MCO2 token. Bitcoin mining is very energy-intensive, and MOSS has calculated that one Bitcoin generates two tons of CO2.

You can buy two MCO2 tokens to offset the carbon footprint of one Bitcoin. (This will cost you $26.) Of course, you can use the tokens – whose proceeds support the Brazilian rainforest – to offset any carbon-emitting activity.

MyClimate

MyClimate is a Swiss nonprofit that has been around for nearly 20 years. They offer offsets for a variety of activities, including flights, cars, cruises, running a household, and much more. There is also a calculator for your carbon footprint.

MyClimate targets EU residents, but you can buy offsets from anywhere (USD pricing is available.) According to MyClimate, an average EU resident emits 8.4 tons of carbon annually, which costs $250 to offset (nearly $30 per ton if you pick the default project selection.)

MyClimate is the priciest of all the offset companies we’ve reviewed. You can also pick individual projects for your offsets, some of which are even more expensive.

Native

Native is a Public Benefit Corporation and a certified B Corp that has been around for over 20 years. The offsets you can buy on the site support projects working with the hunter-gatherer Hazda communities to protect forests in Tanzania. The offsets are pricey at $15.5 a ton. Native offers calculators for travel, running a household, and events.

Sustainable Travel International

Sustainable Travel International focuses on emissions from travel and tourism. They offer a calculator for each flight you take. For example, a long-haul flight can emit as much as 4,406 pounds of CO2 (equivalent to 2 metric tons), which will cost you $25 to offset.

Terrapass

Terrapass sells carbon offset subscriptions based on how much carbon you emit each month from home energy use, driving, flying, and household waste. There are separate offset packages for flights and certificates to support renewable energy. Terrapass also has a handy calculator to determine your individual carbon footprint. They currently charge $4.99 for 1,000 pounds of carbon ($4.49 with a subscription), which is roughly $11 per metric ton ($9.9 with a subscription.)

Wren

Wren is an easy-to-use carbon offset company that provides a comprehensive calculator, which considers your zip code, what car you drive, how much you fly, if you eat red meat, and even the size of your apartment. An average user pays $23 per month to offset their carbon footprint.

Offsets are offered on a subscription basis and currently cost $18 per ton of CO2. Wren has a very informative website full of educational materials. They even let you compare your emissions to the U.S. average and other countries like India. (According to Wren, an average American emits nearly 9x as much carbon as an average Indian.)
