Greenhouse Gas Measurement and Management


Physical measures include transport infrastructure (including designated lanes for buses and taxis, pedestrian areas, cycling network), renewable energy, retrofitting of buildings, district heating and tree planting. Changwon is “constructing green networks (parks, roads and rivers)” and also “implementing a One Million Tree Project”. Importantly, 17 responding cities reported awareness-raising as an important means of reducing GHG emissions in their communities.


Financing GHG reduction measures Despite the large number of cities reporting a reduction target, only a few of these cities calculate the financial investment that may be required.


London has “estimated that £40bn will be required to meet the Mayor’s target to reduce CO2


emissions by 60


percent (1990 levels) by 2025.” In order “to deliver the Mayor’s existing climate change mitigation programme in full it is expected to cost in the region of £14bn by 2025.”


“After a thorough analysis of the various mitigation and adaptation measures, and after evaluating their potential GHG emission reduction, the City of Buenos Aires has set a goal to reduce 32.7 percent of GHG emissions by 2030 in reference to emissions in 2008.”

“Hong Kong Government has proposed...to adopt a voluntary carbon intensity reduction target of 50% - 60% by 2020 as compared with 2005 level through the implementation of proposed action agenda.”
