Boycott
Definition
A collective, organised refusal to purchase from, associate with or otherwise deal with a company, brand or country, intended to coerce a change in behaviour. The term derives from Captain Charles Cunningham Boycott, an English land agent in Ireland who in 1880 was socially and economically ostracised by the Irish Land League — an episode that gave the tactic its name.

Overview
What it means
In sustainability contexts, boycotts are the "stick" of political consumerism: consumers withdraw purchases over environmental damage, labour abuses, animal welfare or human-rights concerns — historical examples include boycotts over sweatshop labour conditions.
Effectiveness depends on visibility, participation and the target's brand sensitivity; organised consumer pressure has repeatedly forced supply-chain reform commitments. The mirror-image tactic, organised buying to reward good conduct, is the "buycott" (or "carrotmob").
How it is used
Campaign groups, unions and consumer movements call boycotts; companies respond through remediation, certification and disclosure. Sustainability risk frameworks track boycott exposure as a reputational and demand risk.
Why it matters
Boycotts demonstrate that market access itself can be conditional on conduct; they remain one of the fastest ways publics can impose accountability ahead of regulation.
