A zero-carbon city is a goal of city planners [1] that describes a significant reduction in carbon use by a city. The term describes a range of carbon reduction, ranging from a city that generates as much or more carbon-free sustainable energy as it uses, [2] to a city that manages greenhouse gas emissions and reduces its carbon footprint to a minimum (ideally 0 or negative) by using renewable ...

It is often called simply net zero. [2] In some cases, emissions refers to emissions of all greenhouse gases, and in others it refers only to emissions of carbon dioxide (CO 2). [2]

Its practitioners often attempt to reduce their ecological footprint (including their carbon footprint) by altering their home designs and methods of transportation, energy consumption and diet.
In order to stay under 1.5 °C of global warming, carbon dioxide (CO₂) emissions from G20 countries need to decline by about 45% by 2030 and attain net zero in 2050. [18] To be able to meet the 1.5 °C or even 2 °C, which is the maximum set by the Paris Agreement , greenhouse gas emissions must start to fall by 7.6% per year starting on 2020 ...
Google was at the leading edge of large technology companies seeking to go completely carbon neutral, having declared that status in 2007, and subsequently matching all of its global electricity ...
