How does Carbon+Alt+Delete calculate your carbon emissions?
We start from the average annual carbon emissions per person in your country in our basic calculator (Eurostat data).
You can personalize your CO2 emissions in our detailed calculator. We consider three sources of carbon emissions: lifestyle, housing, and transport (road and air). For each of these sources, we multiply carbon factors (i.e., carbon emissions per unit of use) with your personalized annual use. For instance, the carbon factor of a diesel car is (on average) 177 gram CO2-equivalent per driven kilometer. If we multiply the carbon factor with your annual driven kilometers, we obtain the annual emissions from your car transport. The carbon factors are taken from DEFRA (UK’s department for the environment, food and rural affairs) and WWF Footprint Calculator.
Note that we consider all greenhouse gas emissions, not only CO2. Therefore we work with CO2-equivalent carbon factors.
How does Carbon+Alt+Delete delete carbon emissions?
We buy Voluntary Emission Reductions (VER’s) verified and approved by Gold Standard.
Carbon-neutral projects resulting in emission reductions (e.g. renewable energy) receive one VER for each tonne of CO2 reduction. In other words, we financially support carbon-reducing projects.
Gold Standard is a certification body that guarantees that the money is well spent and that carbon emissions are truly reduced. Moreover, every project certified under Gold Standard must also contribute to at least three of the UN Sustainable Development Goals (SDGs). In this way, lowering greenhouse gas emissions also leads to positive side-effects like creation of new jobs, improved gender equality, improved health, and the protection of natural ecosystems, biodiversity and endangered species.
We currently support a wind power project in Madhya Pradesh in India, where 67 wind turbines are installed of 1.5 MW each. These wind turbines replace electricity from fossil fuel power plants, such as coal-fired plants. More information can be found here.
What does Carbon+Alt+Delete do with my donation?
All donations we receive are used to delete carbon emissions (see the FAQ above for how we do this). As a non-profit organization, we don’t make any profit on our operations. A small part of the donations (less than 10%) is used to cover our operational costs (such as web hosting and payment systems). We are no trader in CO2 emission rights, but use your donation to financially support projects that reduce CO2 emissions.
We maintain a registry to have an overview of all carbon emissions we have deleted and to link them one-to-one to the donations we receive. This registry shows the unique tracking number and time stamp of each group of deleted emission. The time stamp is the exact moment when we received a donation. As such you can verify that the tracking numbers and time stamp of your donation link one-to-one to a group of deleted emissions.
Why is Carbon+Alt+Delete no longer deleting EU ETS emission certificates?
In 2017, Carbon+Alt+Delete compensated carbon emissions by deleting emission certificates from the European Emission Trading System (ETS). As the total amount of certificates was set fixed by the European Union (i.e. the cap), deleting one certificate resulted in a reduction of one tonne of CO2.
On November 9 2017, the European leaders agreed to introduce several new measures and adaptations to the ETS. One of the new measures gives the European Union the possibility to lower the cap if too many certificates remain unused. Specialists foresee that, as a result of this new measure, the European Union will take certificates away from the system to lower the cap between 2020 and 2030. This implies that the certificate that you delete today, will partly be deleted by the European Union anyway. Therefore we have decided to stop deleting ETS emission certificates as of November 9 2017. More information can be found in this Nature paper.
Going forward, we have decided to update the way we compensate your emissions to make sure that there is a real impact. See the FAQs above for how we compensate emissions today.
Where can I find more information on climate change?
There is a lot of material out there on climate change. Some of it is very good (correct, nuanced), some of it not. The best source of information is the Intergovernmental Panel on Climate Change (IPCC) which publishes every 6 years a detailed assessment report on climate change. These reports explain the physics behind climate change, who is contributing to it and how we can limit its impact.
