Carbon Emission Reduction

With the adoption of the Paris COP21 Agreement, developed countries are being asked to set emission limits for the coming decades. The size of the reductions is currently the subject of international debate. These indicators intended to contribute to the analysis and assessment phase leading up to the adoption of new targets and timetables for the urban environment. These indicators will aid city decision makers in their examination of what might constitute cost‐effective strategies for limiting CO2 concentrations to alternative levels. The indicators can also be used to explore the implications for near‐term mitigation decisions both at a macro (city) and micro (building) level.

Indicator 1: Consumption of Renewables
This indicator has been included as it enables decision makers to determine the penetration of renewable energy sources into the urban energy mix.

Indicator 2: GHG emissions per sector (residential, industry, use type)
This indicator has been included as the determination of GHG emissions is critical in order to marshal responses and develop solutions for sectors producing GHG in urban settings.

Indicator 3: Renewable plants (managed by public/private authority) kWh produced
This indicator has been included as the location of such energy generating infrastructure in the urban environment may offset emissions
More Details
Indicator 4: Energy consumption of public buildings
This indicator has been included because it has the potential to inform decision makers in municipalities as to the performance of buildings under their control and how interventions therein may enhance the energy consumption qualities of their building portfolio.

Indicator 5: Total waste generated per year per capita
This indicator has been included in order to quantify the emissions equivalent of the waste volumes generated in the urban environment
More Details
Indicator 6: Brownfield versus Greenfield development
This indicator has been included as it enables decision makers to determine the penetration of renewable energy sources into the urban energy mix.

Indicator 7: Roof Space available for PV
This indicator was selected for inclusion as it would enable decision makers to consider the viability of incentivising the development of available and suitable roof spaces for energy generation

Indicator 8: Roof Space Available for Solar Thermal
This indicator was selected for inclusion as it would enable decision makers to consider the viability of incentivising the development of available and suitable roof spaces for energy generation
