World Earth Day.

World Earth Day is celebrated on 22 April each year, and is marked by events to promote environmental awareness around the world. The day was first marked in the US in 1970, as a response to the 1969 Santa Barbara oil spill, in which an oil well 10 km off the coast of Santa Barbara blew out, resulting in the release of an estimated 11 million litres of crude oil into the Pacific Ocean, killing more than 10 000 Seabirds, Dolphins, Seals, and Sea Lions. Events have been held internationally since 1990, and the Paris Agreement on Climate Change was signed on World Earth Day in 2016.

Events on World Earth Day are coordinated by the Earthday organisation, which describes its mission as 'to broaden, educate and activate the environmental movement worldwide', and works with over 150 000 partner organisations in more than 192 countries around the world.

The theme of World Earth Day 2026 is 'Our Power, Our Planet ™', which has been chosen to reflect the 'Fundamental truth that transcends political cycles. Environmental stewardship has never depended on a single administration, institution, or election. It is sustained by the daily decisions of communities, educators, workers, innovators, and families who understand that protecting the places they live and work is both a responsibility and a long-term investment.'

The aim of Earth Day 2026 is to affirm that environmental progress is real, resilient, and ongoing despite policy uncertainty. Innovation, education, and community problem-solving remain durable. Local systems - cities, schools, Tribal nations - continue implementing solutions that strengthen energy reliability, conserve resources, and reduce risk because they’re grounded in economic sense and public safety. 

This aim is built upon two pillars.

Pillar One: Resilience and Institutional Continuity. 

• The work continues regardless of federal policy. 
• Environmental action is local and decentralised - policy shifts happen in your town, not just Washington. 
• Progress is already operational, not aspirational - solar programs, efficiency investments, ecosystem restoration exist and are working. 
• Economics, education, and conservation outlast political cycles - these don't disappear with an administration change. 

Pillar Two: Shared Interests and Interconnected Outcomes. 

• Environmental protection affects everyone, everywhere. 
• Human health - asthma, lead, climate-driven illness affect real families. 
• Economic security - farmers, fishers, firefighters all depend on a healthy environment. 
• Spiritual & moral values - stewardship of the Earth isn't political, it's biblical. 
• Global ecosystems - what happens over there affects what happens here. 
• Quality of life - can my kids fish in the local stream? Can they breathe clean air?
