When Earth Day 2022 is celebrated around the world on Friday 22 April it will be its 52nd anniversary. But what is its history and what progress, if any, has been made since it was first celebrated in 1970?

What is Earth Day?

Earth Day is an annual global event to demonstrate support for environmental protection and highlight how we can take action. Marked on 22 April each year, it is coordinated via

Sometimes the week running up to it is referred to as Earth Week. According to the organisers, it is recognised by around one billion people from more than 190 countries.

What are its origins?

The first Earth Day came about after a 1969 oil spill in Santa Barbara, California.

In April 1970, 20 million Americans demonstrated – 10% of the US population at the time – in different cities in protest against air and water pollution.

At the time there were not the legal or regulatory mechanisms to protect our planet that exist in the US today, such as clean air and clean water acts.

Senator Gaylord Nelson is credited with forcing environmental issues onto the US national agenda as Earth Day’s founder.

Inspired by the student anti-war movement, he had announced the idea of a “teach-in” on college campuses to the US media and enlisted the help of an activist called Denis Hayes.

Groups that had been campaigning for the environment individually then became united around a common cause and the chosen date of 22 April.

What was the impact of the first Earth Day in 1970?

The protests led to the creation of the US Environmental Protection Agency and first-of-their-kind environmental laws.

According to, these laws have “protected millions of men, women and children from disease and death and have protected hundreds of species from extinction”.

How did Earth Day become an international campaign?

By 1990 Denis Hayes – described by Rolling Stone as “the Mark Zuckerberg of the environmental movement” – had been approached by environmental leaders to mobilise another campaign for the planet. Earth Day 1990 went global and in 1992 the United Nations Earth Summit was held in Rio de Janeiro, Brazil.

As the millennium approached Hayes agreed to spearhead a campaign focused on global warming using digital media.

How is Earth Day marked?

In 2010 The Earth Day Network launched A Billion Acts of Green, the collection of one billion commitments from individuals, businesses, governments and organisations.

It aimed to prove that “real change occurs when millions of people commit to it with their actions”.

Meanwhile, The Canopy Project plants trees “to benefit local communities, increase habitat for species, and combat climate change”.

Action taken ranges from community action, like clean-ups or “citizen science” helping to add to global databases of knowledge, to political engagement. 

What is the theme for 2022?

Earth Day 2022’s theme is Invest in our Planet. has published 52 ways to get involved, including standing against deforestation, asking for green power and signing petitions.

This year’s Earth Day comes just weeks after the Intergovernmental Panel on Climate Change’s third update this year emphasising that emissions must be dramatically reduced within this decade if we are to limit global warming to the Paris Agreement target of 1.5°C. 

Kathleen Rogers, President of, has said: “If we are to make the Paris Agreement mean anything at all then we must work together. This means everyone from individuals, businesses, governments, and other parts of civil society have to commit to a transformative shift in the global economy.

“The solutions are out there and we know what must be done, whether it’s transitioning to renewable energy, conserving our forests and lands, or ridding ourselves of the scourge of plastic pollution.”

What has this got to do with investing?

The way we invest can also make a difference to the environment – and companies and countries’ impacts on the planet are increasingly hitting their bottom lines.

Kate Rogers, Head of Sustainability for Schroders’ wealth business, which includes Cazenove Capital, has long argued the importance of investors looking beyond profit.

She has said that thankfully things are changing and recognition that businesses can either be part of the problem or part of the solution is increasingly part of the discourse. She says: “Investors are recognising that companies can’t exploit the planet without recourse through financial cost or reputational risk.”

Andrew Howard, Global Head of Sustainable Investment, said: “Stakeholder pressure and government intervention are forcing companies to take responsibility for the environmental and social impacts their actions create. Costs that were previously externalised to society will become internalised on companies’ financial statements.”

This is why new approaches to investment analysis are needed to identify, measure and manage the impacts of these changing pressures.

SustainEx, a powerful tool used by Schroders’ investment experts, measures the costs companies would face if all of their negative externalities were priced, or the boost if benefits were recognised financially. 

Howard says: “Companies don’t operate in a vacuum – they are affected by society and have impacts on society.”

Schroders has supported the Earth Day movement through internal awareness campaigns since 2018 and encourages its employees to join the conversation by taking climate action. In 2021, Schroders  launched six easy steps to net zero and colleagues pledged to adopt greener habits.

This year’s efforts are focused on hosting volunteer and environmental initiatives to enable employees to invest time in their local environments. These range from sustaining Pocket City Farm’s mission to encourage sustainable eating and sourcing of food in Sydney, regenerating a primary school’s playground with vegetable gardens in London to tree planting in the mountain village of Hinohara in Tokyo.
