Montreal Protocol likely in eastern Asia, with detrimental global effects on the ozone layer. A monitoring study detected fresh atmospheric releases of carbon tetrachloride from China's Shandong province, beginning sometime after 2012, and accounting for a large part of emissions exceeding global estimates under the Montreal Protocol. The year 2012 marked the 25th anniversary of the signing of the Montreal Protocol. Accordingly, the Montreal Protocol community organized a range of celebrations at the national, regional and international levels to publicize its considerable success to date and to consider the work ahead for the future.
