Buildings are one of the biggest sources of greenhouse gas (GHG) emissions, accounting for over half of total city emissions on average, and a significant source of air pollution. Currently, half a million people die each year due to outdoor air pollution caused by energy used in buildings. Delivering on the goals of the Paris...

This report intends to be a guide to assist the decision-makers in cities that recognise the challenges of food waste management and wish to find sustainable and effective solutions.

This report presents the methodology and results of a study investigating the consumption based greenhouse gas emissions (GHG) from 79 cities, carried out by the C40 Cities Climate Leadership Group (C40) in partnership with the University of Leeds (United Kingdom), the University of New South Wales (Australia), and Arup.

This report presents the methodology and results of a study investigating the consumption-based greenhouse gas emissions (GHG) from 79 cities. To support evidence-based climate action planning, many cities have developed sector-based GHG inventories using standards such as the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC).
