The lifecycle carbon footprint for a half litre of small pack bottled water is 111 grams CO 2 equivalent. [35] By comparison, the same sized PET plastic-bottled soft drink produces 240 grams CO 2 equivalent. Soft drink bottles require much thicker plastic due to carbonation, and therefore many more grams of CO 2 equivalent.
The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO 2-equivalent) per unit of comparison.
Coca-Cola is committed to collecting and recycling plastic bottles rather than switching to aluminium cans as the world's largest soft drinks maker seeks to reduce its carbon footprint, its chief ...
Regardless of where it was emitted from, emissions are roughly spread across the world and become mixed into a heterogeneous mixture. They are calculated in parts per million (ppm), parts per billion (ppb), and parts per trillion (ppt). In 2019, data states that there was 409.8 parts per million of carbon dioxide in the atmosphere.

Some people foresee a true sustainable steady state economy that may be very different from today's: greatly reduced energy usage, minimal ecological footprint, fewer consumer packaged goods, local purchasing with short food supply chains, little processed foods, etc. [40] [41] [42] Less packaging would be needed in a sustainable carbon neutral ...
A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
Singapore: plastic bottles are collected with glass bottles. The stream in which PET bottles are collected comprises PET bottles, other plastic bottles and glass bottles, and contamination. Switzerland: Retailers contribute a fee to a national operator (PRS) who manages collection bins, sorting and production of rPET flake.
