WHY? a regional emission inventory
WHY? helps local governments
WHY? helps local governments
SET GOALS AND TARGETS FOR
FUTURE REDUCTIONS
IDENTIFY THE
SECTORS, SOURCES AND
ACTIVITIES
ESTABLISH A BASIS FOR
DEVELOPING A LOCAL
STRATEGY
UNDERSTAND EMISSION TRENDS
QUANTIFY THE BENEFITS OF ACTIVITIES
TRACK
PROGRESS IN REDUCING EMISSIONS
YES! Can we do without it?
• Measures with no implementation costs or short pay-back periods – Behavioral changes – Energy efficiency technologies
• Short-term funding opportunities • Integration with existing policies
IMPLEMENTATION RIGHT AWAY! ECONOMIC BENEFITS AND GHG
REDUCTIONS!

WHAT options do we have?
Boundaries • Community • City or municipality • Region
• Organization • Government
operations
GEOGRAPHICAL
ORGANIZATIONAL
Boundaries • Energy
– Heat, electricity, other fuels
• Transport – Road, rail, marine, air
OPERATIONAL
• Waste treatment • Agriculture • Industrial processes
Boundaries • Carbon dioxide (CO2) • Methane (CH4) • Nitrous oxide (N2O) • Hydrofluorocarbons (HFCs) • Perfluorocarbons (PFCs) • Sulphur hexafluoride (SF6)

Scope
DIRECT OR INDIRECT EMISSIONS?
ENERGY PRODUCTION OR CONSUMPTION?
OTHER PRODUCTION AND CONSUMPTION?
Scope 1
CH4
Direct emissions PRODUCTION-BASED
• All energy production, industrial processes, fuel use, agriculture, traffic and waste treatment in the area
CONSUMPTION-BASED
Scope 2
CH4
Direct emissions
Indirect emissions
• Purchased electricity (and heat)
• Sold electricity and heat
(Energy)
• Energy produced and used, industrial processes, fuel use, agriculture, traffic and waste treatment in the area
Indirect emissions
CONSUMPTION-BASED
Scope 3
CH4
Direct emissions
Indirect emissions
• Purchased energy, goods and materials, food etc.
• Energy produced and used, fuel use, traffic and waste treatment in the area
• Transport generated and waste treated outside the area
(Full)
• Sold electricity and heat
• Industry • Agriculture
- Set boundaries - Define scope - What data is available?
So let’s make an inventory…
Quantification approach • Data collected by national and
international agencies Disaggregation to regional level by means of available statistical indicators
• Data directly from from local
end users and utilities START HERE and use top-down approach when necessary
TOP DOWN
UP BOTTOM
Baseline year • A benchmark to compare progress
going forward – Enough reliable data for that year? – Economically and climatically ’neutral’
year? – Comparability to other
regions/inventories?
1990
2012
2005
2014
200?
- Set boundaries - Define scope - What data is available? - Engage stakeholders - Think about reporting
So let’s make an inventory…
Stakeholders • Energy companies • Transportation
agencies, operators • Oil retailers • Statistics, etc..
• Decision makers • General public • …
DATA PROVIDERS
TARGET GROUPS
Reporting 1 • By energy type?
– Heating – Electricity – Transport – Other fuels – Non-CO2 from industrial processes, waste and agriculture
GHG source categories
Reporting 2 • By fuel type?
– Coal – Gas – Oil – Other fuels – Non-CO2
GHG source categories
Reporting 3 • By end user?
– Residential – Services – Public sector – Industry – Agriculture
GHG source categories
- Set boundaries - Define scope - What data is available? - Engage stakeholders - Think about reporting

• Helsinki, Espoo, Kauniainen, Vantaa – 1,1 million inhabitants – 650 000 jobs – 770 km2
Helsinki Metropolitan Area Climate Strategy 2030 • The strategy was completed in 2007 and approved by the
HMA cities in 2008 • A steering group decided on the emission calculation
methodology • Inventories were made for 1990 and 2004
7,0 1990 2030
(tonnes CO2e per capita)
-39 % target 4,3
Helsinki Metropolitan Area Climate Strategy 2030 • Reduction targets were revised in 2012 • -20 % by 2020 (total emissions) and
carbon neutrality by 2050
• From 2009 annual emissions assessments now covering the years 1990 and 2000-2013.

Sectors included?
Greenhouse gases
• Carbon dioxide (CO2) • Methane (CH4) • Nitrous oxide (N2O)
Other
climate forcers
Scope of activities • Energy consumption -based
Data collection and calculations
District heating
• Power plant environmental reports • Fuels used and energy produced
Allocate fuels in CHP Calculate the emissions from production
(using the IPCC emission factors) • Energy consumed in the area and sold outside
Calculate the emissions from consumption
HEATING
Data collection and calculations
Oil and electric heating
• Building floor areas by heating method • Consumption key figures (kWh/m2)
Calculate the estimated
energy consumption and emissions
(using emission factors for electric heating and light fuel oil)
HEATING

Heating energy standardization
• Heating degree days from the reporting year compared to long-term average
Calculate standardized energy consumption and emissions from district, oil and electric heating
HEATING
Methodology
• ”All electricity produced in the area is sold to the Finnish electricity market”

Take-home MESSAGE
1. Plan carefully and define options together with
the stakeholders. 2. Do not try to have it all - a useful inventory is
comprehensive but simple and relevant 3. Make the process repeatable and put effort in
reporting and visualizations. 4. Learn from your neighbours.
