100%

Production Capacity of Gaswork Gas refers t o the comprehensive production capacity of t he urban gasworks in gas
generation, purification and delivery at the end of the reference period, excluding capacity of the reserved facilities. In
general, it is determined by the des igned capacity, and when actual production capacity is larger t han the designed capacity,
the capacity is determined by the actual measurement on the weakest link in the production, purification and delivery.

Length of Gas Pipel ine s refers t o t he total length of pip elines in us e between the outlet of the comp ressor of gaswork
or out let of gas stations and t he leading p ipe of users, excluding pipelines within gasworks, delivery stations, LPG storage
stations , refilling s tations, gas-mixing stations and sup ply stations.

Volume of Gas Supply refers to the total volume of gas provided to users by gas-producing enterp rises (units) in a year,
including the volume sold and the volume lost.

Percentage of Urban Popul ati on with Acces s to Gas refers to the ratio of the urban population with access to gas to
the total urban p opulation at the end of the reference period. The formula is:

Percentage of population with access to gas = (Urban population with access to gas / Urban population) x 100%

Heating Capacity in Urban Area refers to the designed capacity of heating enterprises (units) in supplying heating
energy to urban users during the reference period.

Quantity of Heat Supplied in Urban Area refers to the total quant ity of heat from steam and hot wat er sup plied to
urban us ers by heating enterpris es (units ) during t he reference period.

Length of Heating Pipel ines refers to the total length of steam or hot water pipelines for sources of heat t o the leading
pip elines of the buildings of the users, excluding internal pipelines in heat generating enterp rises.

Length of Paved Roads at the Year-end refers t o t he length of roads wit h paved surface including squares bridges and
tunnels connected with roads by the end of the year. Length of the roads is measured by the central lines for vehicles for
paved roads wit h a width of 3.5 meters and over, including roads in open-ended factory compounds and residential quarters.

Urban Bridges refer to bridges built to cross over natural or man-made barriers, including bridges over rivers, overpasses
for traffic and for p edes trian, underpasses for pedestrian, etc. Both p ermanent and semi-permanent bridges are included.

Length of Urban Sewage Pipes refers to the total length of general drainage, trunks. branch and inspection wells,
connection wells, inlets and outlets , etc.

Daily Disposal Capacity of Urban Sewage refers to the designed 24 hour capacit y of sewage disp osal by the s ewage
treatment works or facilities.

Numbe r of Vehicles under Operation at the Year-end refers to the total number of vehicles under operation by public
transport enterprises (units) at the end of the year, based on the records of operational vehicles by the enterprises (units).

Area of Urban Gardens and Green Areas refers to the total area occupied for green projects at the end of the reference
period, including public green land, green land in residential quarters, green land attached to inst itut ions, prot ection green
land,production green land, roadside green land and forest in scenic spots. It does not include the following:

(1) Greenery and p lants on roofs, balconies , indoors and vertical green areas;

(2) Forest, cultivated land grassland, orchards and bamboo grooves that are for production purpos e; and

(3) Water areas that are not included in urban master plan as green land.

Public Green Area refers to green areas open to the public such as municipal, community and neighborhood parks and
roadside parks, including waters within parks. Neighborhood p arks should occupy an area larger than 10,000 square meters,
and the width of roads ide parks should occup y an area larger than 400 square meters, with a width of more that 8 meters.
