Online gay speculation is the practice of speculating about the sexuality of a person on platforms such as Tumblr or Twitter (X). Gay speculation communities often theorize about their idol's private life, create fan content about their sexuality, and are critical of the person's real life partner. Examples include the "Gaylor Swift" and "Larry Stylinson" fandoms.

The Carbon Border Adjustment Mechanism (CBAM) is a carbon tariff on products that are imported by the European Union. CBAM calculates the amount of carbon emitted in the production of each good, imposing a proportional tariff on those goods that exceed a predetermined threshold. If importers can prove that a carbon price has already been paid locally in the production of the imported goods, the corresponding amount can be deducted from the tariff.
