2、 2 Introduction The IPCCs Sixth Assessment Working Group III Climate Change report shows that climate change is already having a serious impact on ecosystems and communities around the world.This provides ever more evidence that we urgently need to cut greenhouse gas(GHG)emissions to limit global wa

3、rming to 1.5C above pre-industrial levels and to avoid catastrophic climate change.Accounting for an estimated 70%of global emissions and home to 55%of the global population,cities1 have a critical role to play in this transition.A key part of a citys journey to taking effective climate action is to

4、 understand the GHG emissions generated by different activities within their geographic area,sometimes referred to as community-wide or city-wide emissions.To do this,cities develop an emissions inventory.A GHG emissions inventory provides a breakdown of a citys emissions by activity or sector,and s

5、cope(where the emissions physically occur,relative to the citys geographic area).It is crucial for informing city climate policy and decision-making,setting meaningful science-based climate targets and monitoring progress towards those targets.A GHG emissions inventory is critical for effective city

6、 climate action planning Developing a robust and comprehensive GHG emissions inventory:1)Helps cities establish a base year emissions inventory and set reduction targets;2)Enables cities to benchmark and compare their emissions with other cities;3)Helps cities to prioritize city climate actions,thro
