Improving energy efficiency in buildings can substantially reduce energy consumption and CO2 emissions, while also stimulating job creation and making energy more affordable for households.
These are the speaker presentations given at the OECD Decarbonising Buildings in Cities and Regions webinar on 14 December 2020
6. Decarbonising buildings: global context

Note: 2018, OECD, Romania and Bulgaria. Regional estimates exclude emissions from land use and land use change. National emissions are attributed to proxies,
including locations according to population, buildings, industrial and energy supply point sources, infrastructure, traffic flows and local data on agricultural activity.
Metro regions emit 60% of GHG emissions
in OECD, with high share from buildings.
Best-performing regions consume 3 times
less energy at home.

10. Energy efficiency renovation for local growth
Most of construction firms are SMEs,
and severely hit by COVID-19.
• In EU, 94% of firms in construction of buildings are
those with less than 9 employees.
Energy efficiency renovations involve
a diversity of suppliers.

11. Cities and regions have a unique ability
Cities and regions can leverage public
building procurement for energy efficiency.
Cities and regions are familiar with key
local factors.
• Strategic approach to building stock
• Building database development
• Subnational governments account for 60% of public
investment in OECD countries.

12. Cities and regions are taking lead in local
innovation and experimentation.
Cities and regions can engage citizens and
local businesses effectively.
Homeowners
• Ambitious target setting / regulations
• Low-carbon district development / smart grids
• New business model & financing scheme
• Assistance to low-income households (energy poor)
• “One-stop shop” services for citizens
• Bundling renovations needs
Cities and regions are taking innovative actions

Energy efficient homes can, through renovation & new technology reduce
energy bills, improve health and living conditions and help our climate.
Around EUR 275 billion of additional investments in building
renovation is needed per year to achieve the 2030 targets.
Building renovation is EU's biggest job creator with
12-18 local jobs/million euro invested.
Focus areas: energy poverty & worst
performing buildings, public buildings,
heating & cooling.

38. Energy
Regions and cities directly manage large parts of the building
stock, including: schools, hospitals and service buildings.
Local authorities have an important role in shaping the
regulatory framework, market conditions and skills and in
creating a robust pipeline of projects to finance the
modernisation of buildings and their heating and cooling
systems. They can drive district approaches to decarbonising
the built environment.
Close partnership with the Committee of the Regions,
Covenant of mayors, and local and municipal authorities, and
the Smart cities marketplace. And strengthening of technical
assistance for local and regional authorities.

and cities playing a central role

The Recovery Plan makes available to Member States
substantial funds under the Recovery and Resilience Facility,
which can be used for building renovations.
“Renovate” as one of the priority flagship component.
Member States, regions and local authorities should
seize the opportunity to finance investments in a local
context as part of the territorial instruments within the
various financing instruments
Renovation at the heart of a green recovery
43. Profile and mission
Multilateral development bank
The oldest international financial institution in Europe (1956)and the only one with
an exclusively social mandate
Initially established to tackle the problems of refugees, its scope has progressively
widened to other sectors strengthening social cohesion in Europe
Strategic priorities of the Development Plan 2020-2022
Inclusive growth
Support for vulnerable groups
Environmental sustainability
Focus on further engaging with subnational entities- cities and regions.
In line with its social mandate the CEB is fully committed to providing timely, flexible and
targeted financing.
The CEB: Europe’s social development bank
44. CEB’s unique mandate – promoting social cohesion in Europe- makes it a natural
partner for regions and cities planning for a more sustainable future.
Subnational Governments are responsible for a quarter of all public expenditures and almost half
of all public investment.
Access to funding and knowledge is crucial at local level for creating an integrated approach to
territorial, programmatic, impact oriented and multi sectoral policies.
CEB’s increased engagement with sub-national authorities and municipalities
Facilitate access to financial resources through flexible financing for local investments.
Upgrade and reduce gaps in social infrastructure
Increase access to and/or the ability to absorb EU funds.
Subnational financing at CEB is increasing
Between 2014-2019 the CEB approved almost €8 billion in loans to support social projects
locally across Europe.
1.4 billion EUR in 2019 and 1.7 billion EUR in 2020.
CEB: a trusted partner for Cities and Regions
45. Energy Efficiency renovation of buildings in CEB financing
Since 2002, € 2.4 billion approved in favour of projects wholly or partially
concerned with EE. More than 75% was devoted solely to EE.
Main focus for CEB: social housing, national public programmes, public buildings
and services from local and regional authorities, as well as EE needs for SME and
homeowners.
Supporting Energy Efficiency renovation through cities and regions
Direct loans to municipalities, regional governments and other public entities to
support projects related to EE renovation of their own assets.
EE renovation is included as a component of most CEB loans to subnational
authorities.
Decarbonising building is increasingly a priority for subnational counterparties.
Decarbonising buildings in Cities and Regions
46. EE renovations are linked to the specific local conditions of the building stock,
socio economic, institutional and geographical contexts.
High level of fragmentation of the EE renovation market: larger financial flows
have to be aggregated by a single entity, such as sub-nationals, equipped to
interface with IFIs.
Multiplicity of actors and financial sources increases complexity.
Public authorities can optimize their financing by making best use of available
national or EU support programs or/and using innovative financing blending
mechanisms.
Investment programs are more effective when carefully designed based on
relevant energy and climate studies and strategies (evaluation of the energy
savings potential, setting of energy and climate objectives, and preparation of an
action plan with clearly defined targets)
Measuring and monitoring targets and results may be challenging.
Lessons learned
47. Decarbonising buildings as a win win win strategy for recovery
e.g. the European Renovation Wave.
CEB stands ready to support its clients to fulfill such objectives: reduce emission,
boost recovery and reduce energy poverty.
Key role of cities and regions in decarbonising the building stock.
Build back better locally and contribute to an inclusive and climate change resilient
recovery, while particularly enhancing social benefits at the local level.
Challenges for Cities and Regions
Decarbonisation of buildings face delays in many markets due to lock-downs and
social distancing (IEA report).
Assessment of aggregated targets for decarbonising buildings, progress
monitoring and measuring potential benefits and policy outcomes.
Way forward and challenges for a green and
sustainable recovery
