when was the first international earth day celebrated?
in 1970
two separate groups formed to sponsor earth day events in 1990: the earth day 20 foundation, assembled by edward furia (project director of earth week in 1970), and earth day 1990, assembled by denis hayes (national coordinator for earth day 1970). senator gaylord nelson, the original founder of earth day, was honorary chairman for both groups. the two did not combine forces over disagreements about leadership of combined organization and incompatible structures and strategies. among the disagreements, key earth day 20 foundation organizers were critical of earth day 1990 for including on their board hewlett-packard, a company that at the time was the second-biggest emitter of chlorofluorocarbons in silicon valley and refused to switch to alternative solvents. in terms of marketing, earth day 20 had a grassroots approach to organizing and relied largely on locally based groups like the national toxics campaign, a boston-based coalition of 1,000 local groups concerned with industrial pollution. earth day 1990 employed strategies including focus group testing, direct mail fund raising, and email marketing.

following the success of the first earth day, hayes founded the earth day network and served as international chairman for earth day's anniversaries in 1990 and 2000. internationally, he is recognized for expanding the earth day network to more than 180 nations. it is now the world’s most widely observed secular holiday. hayes continues to chair the board of the international earth day network and is the chair of the earth day 2010 global advisory committee.
