drink products", then data "on each item's carbon footprint was clearly presented, and individuals could view the [unlimited] carbon footprint of their supermarket basket on their shopping bill." The processes of consumption Not only selection, quantity and quality of consumed products may be of relevance to sustainable consumption, the process of consumption, including how selected products are distributed or gathered could be considered a component of it as well: for instance, ordering from a local store online could substantially reduce emissions (in terms of transportation emissions and when not considering which options are available). Bundling items could reduce carbon emissions of deliveries and carbon footprints of in-person shopping-trips can be eliminated e.g. by biking to the shop instead of driving. Product information transparency and trade control If information is linked to products e.g. via a digital product passport, along with proper architecture and governance for data sharing and data protection, it could help achieve climate neutrality and foster dematerialization. In the EU, a Digital Product Passport is being developed. When there is an increase in greenhouse gas emissions in one country as a result of an emissions reduction by a second country with a strict climate policy this is referred to as carbon leakage. In the EU, the proposed Carbon Border Adjustment Mechanism could help mitigate this problem, and possibly increase the capacity to account for imported pollution/harm/death-footprints. Footprints of nondomestic production are significant: for instance, a study concluded that PM2.5 air pollution induced by the contemporary free trade and consumption by the G20 nations causes two million premature deaths annually, suggesting that the average lifetime consumption of about ~28 people in these countries causes at least one premature death (average age ~67) while developing countries "cannot be expected" to implement or be able to implement countermeasures without external support or internationally coordinated efforts. Transparency of supply chains is important for global goals such as ending net-deforestation. Policy-options for reducing imported deforestation also include "Lower/raise import tariffs for sustainably/unsustainably produced commodities" and "Regulate imports, e.g., through quotas, bans, or preferential access agreements". However, several theories of change of policy options rely on (true / reliable) information being available/provided to "shift demand—both intermediate and final—either away from imported [forest-risk commodities (FRC)] completely, e.g., through diet shifts (IC1), or to sustainably produced FRCs, e.g., through voluntary or mandatory supply-chain transparency (IS1, RS2)." As of 2021, one approach under development is binary "labelling"
