# Giving What We Can

Giving What We Can (GWWC) is an effective altruism nonprofit that promotes effective giving through education, outreach, and advocacy around the 10% Pledge, which encourages members to donate at least 10% of their income to effective charities. It was founded at Oxford University in 2009 by philosophers Toby Ord and William MacAskill.

## History

Giving What We Can was launched as a giving society in 2009 by Toby Ord, an ethics researcher at Oxford, his wife Bernadette Young, a physician in training at the time, and fellow ethicist William MacAskill with the goal of encouraging people to give at least 10% over the course of their working life to alleviate world poverty. This is similar to Ma'aser kesafim (giving 10% of income) in Jewish tradition and zakat in Islam, but Ord said there was no religious motivation behind it. Ord cited writings from Peter Singer and Thomas Pogge about one's moral duty to give to the poor as inspiration for starting the organisation, and personally planned to give away everything above about $28,000 a year, the median after-tax salary in the U.K. His focus was on effective giving, meaning that he emphasised donations to charities which saved a maximal amount of life per donation amount. GWWC was launched with 23 members. People who joined signed a pledge to give away 10% of their income to any organisation they thought could best address poverty in the developing world, and could pledge more; there was no penalty for quitting. By the end of 2011 it had 177 members, mostly other academics, in five chapters including Oxford, Cambridge, Princeton, and Harvard.
By November 2011, the organisation was providing its members regular reports on what charities were most effective at addressing poverty in the developing world, and at that time was recommending a tropical diseases group and a de-worming group that each worked in Africa. Ord relied in part on research conducted by GiveWell, and also used the concept of the quality-adjusted life-year to gauge effectiveness of charities.
In 2011, a sister organisation at Oxford led by MacAskill and others called "High Impact Careers" was spun off from Giving What We Can. This organisation encouraged people to pursue high-paying jobs so they could give more money away. High Impact Careers was soon renamed to 80,000 Hours. In 2012 the two organisations incorporated the Centre for Effective Altruism as a nonprofit to serve as an umbrella organisation. In 2024, Giving What We Can became its own legal entity again.
In its early days, it recommended a selected set of charities in the area of global health. In 2017, stopped conducting original research but rather started to recommend to its members to follow the advice by charity evaluators such as GiveWell, Animal Charity Evaluators and Founders Pledge. Additionally, they recommend a list of individual charities that cover a wide range of causes including global poverty alleviation, animal welfare and the welfare of future generations.

## Research

Giving What We Can used to conduct research to determine which charities it would recommend for members and other people to support. It differed from other charity evaluators in terms of the importance given to metrics of charity performance. While evaluators such as Charity Navigator used the fraction of donations spent on program expenses versus administrative overhead as an important indicator, Giving What We Can solely focused on the cost-effectiveness of the charity's work. It believed that the variance in cost-effectiveness of charities arose largely due to the variance in the nature of the causes that the charities operate in, and therefore made evaluations across broad areas of work such as health, education, and emergency aid before comparing specific organisations. In practice, it recommended a selected few charities in the area of global health. Its work was therefore similar to that of GiveWell. In 2017, the Centre for Effective Altruism stopped conducting original research into giving opportunities based on significant overlap with organisations like GiveWell and the Open Philanthropy Project.

## Pledges

Giving What We Can promotes giving pledges as a means to help individuals align their actions with their values, take concrete steps to improve the world, and influence societal norms around charitable giving. All members share a commitment to donating at least part of their income and are commonly referred to as "pledgers."

### The 10% Pledge

The 10% pledge is a voluntary and non-legal commitment to donate 10% or more of one's income. This figure is the minimum percentage and was chosen because it has a good balance of significant and achievable. It is a significant proportion of income, in recognition of the importance of the problem and the need for real action. But it is also within the reach of most people in the developed world. Some members decide to go further and commit to donating 20% or even 50%.
In late 2023, GWWC added the option to pledge wealth instead of income. This was in recognition of the fact that, for the very wealthy, much of their resources are in the form of wealth rather than income, and so pledging a percentage of wealth would be more in line with the spirit of the pledge. The optional wealth component of the Pledge allows individuals to commit to giving either 10% of their income or a custom percentage of their wealth annually, whichever is greater. Head of TED Chris Anderson who helped develop the wealth pledge option, was among the first to take it.

### Other pledges
#### The Further Pledge

Some members decide to go even further and perform the "Further Pledge". The member defines a basic annual income that they expect to live on. All income above this level will be donated to effective measures.
Founder Toby Ord further pledged to donate anything he earned over £20,000 a year, based on his conviction that he could live comfortably and happily on this income.
Co-founder Will MacAskill is also among those who have made such a pledge.

#### The Trial Pledge

Because some people may be interested but not yet ready to take the 10% Pledge, it is also possible to make a temporary commitment called "The Trial Pledge". This involves making a commitment to donate at least 1% of one's income for a specified period of time.

#### The Company Pledge

In 2020, GWWC launched the option for companies to also declare their commitment to donating to effective organizations. In this case, companies commit to donate at least 10% of their net profits to effective charities. By 2024, 51 companies had signed up.

## Members

By 2012, 264 people from 17 countries had taken the 10% Pledge. It surpassed 1,000 members in 2015 and 5,000 members in 2020.
