About
Stop Paper Racism (#StopPaperRacism) is a youth-led environmental campaign founded by Seoha Han in 2022, now evolving into The World's Sweetest Climate Campaign. Challenging the preference for white, wood-pulp paper, the campaign has reached 100+ institutions, including the National Assembly Library of Korea, through tree-free paper adoptions, partnerships, and national keynotes. The campaign and its founder have received international recognition, including Earth Prize 2026 Scholar, Asia-Pacific Regional Winner of the International Youth Environmental Challenge, and Global Top 100 in the Emerging Innovator Awards. The campaign has also been featured by The Earth Foundation at Earth Day Geneva 2026, We Don't Have Time, and South Korea's Environment Daily.
What we do
We cool the Earth, one page at a time.
We challenge the default.
Society treats white wood-pulp paper as the standard.
We encourage institutions to question this assumption and consider sustainable alternatives based on function, not colour or familiarity.
We help institutions transition to tree-free paper.
We work with schools, companies, and public institutions to test and adopt paper made from agricultural waste and other non-wood fibres.
We save trees.
Approximately four boxes of tree-free paper preserve one mature tree.
We help mitigate climate change.
By preserving natural carbon sinks, we reduce emissions associated with logging and wood-pulp production.
We replace tree-based paper at scale.
When institutions switch procurement, thousands of people begin using tree-free paper every day.
