Latest IPCC Findings
Stern review and Economics
• Tackling climate change is a
“pro-growth strategy”
• Showed that the costs of
action to reduce emissions
now will be 1% per year or
less, whereas the damage
costs of business as usual are
likely to be in the order of 5 to
20 % of global GDP.
• London’s financial services
sector bears the brunt of
impacts wherever they occur in
the world.
• 2005 saw weather-related
catastrophe losses total almost
$80 Billion worldwide, and over
99% of all catastrophic losses
were due to weather–related
events.

Hot in the city
• 600 people died in the
August 2003 heatwave
• London had highest
numbers of deaths for
any UK region
• London’s heat island
means inner London
can be up to 9°C
warmer than the
greenbelt
• Further development
may intensity the heat
island effect

Energy Strategy Objectives
•
•
•
Reduce London’s contribution to climate
change, by minimising emissions of carbon
dioxide from all sectors (commercial,
domestic, industrial and transport) through
energy efficiency, combined heat and power,
renewable energy and hydrogen;
Help to eradicate fuel poverty, by giving
Londoners, particularly the most vulnerable
groups, access to affordable warmth;
Contribute to London’s economy, by
increasing job opportunities and innovation
in delivering sustainable energy, and
improving London’s housing and other
building stock.
Mayor’s Climate Change Action Plan
• Four new programmes
– Green Homes
– Green Companies
– Green Transport
– Green Energy Supply
• Plus action on GLA own
activities and on new build
• An action-based, funded
programme to tackle climate
change

•
Design to minimise CO2
emissions from the outset
Maximise passive design and
integration with CCHP/CHP
All major new developments
should establish or connect to
a local combined cooling, heat
and power network
Minimise need for active
cooling systems
Incentivise new technologies,
as an alternative to fossil fuels
Further Alterations proposals developments to achieve a
reduction in CO2 emissions of
20% from onsite renewable
energy generation
Further Alterations to the London
Plan
Proposed new policy:
•
Boroughs should ensure that all LDFs identify and safeguard existing
heat and cooling networks and maximise the opportunities for providing
new networks that are supplied by decentralised energy. Boroughs
should ensure that all new development is designed to connect to the
heating and cooling network. The Mayor will and boroughs should work
in partnership to identify network opportunities, to ensure the delivery of
these networks and to maximise the potential for existing developments
to connect to them.
Supporting text:
• This area wide approach should provide more market certainty for
Energy Services Companies (ESCo) as it should remove some of the
risk of developments not being designed to connect to decentralised
energy. The scale of opportunity for delivery may also increase
competition between ESCos and encourage the creation of small and
medium size ESCos to deal with the different scales of development.
Main Panel Recommendations on
Climate Change
• Overwhelming support for Mayor’s
approach
• New policy on Living roofs and walls
• New policy on provision of heating and
cooling networks
• Clarification on SPG on Renewable
energy and investigation of strategic fund
• Review of SPG on Sustainable design and
construction and standards in relation to
Code for Sustainable Homes
Panel recommendations (2)
• Adaptation policy – add minimising water
use and green infrastructure
• Reference to role of soft landscaping in
front gardens
• Standard for water usage in homes
reduced to 105 litres/person/day for
consistency with level 3 of Code

UK Power Flow Pattern 2006/7
• broad estimate is that
only 40% of the heat
generated in the
combustion process in
grid power stations is
used in the generation of
electricity
• Losses in power through
transmissions and
distribution amount to
approximately 9% of
demand

Barriers to Increased Decentralised
Energy
•
•
There are serious market barriers which prevent decentralised energy from
expanding to meet the climate change targets required of it.
These are all matters that involve the interface between decentralised energy
and the market for large scale, centrally generated electricity production:
i) For all but the small schemes (which currently have licence exempt status),
the costs and burdens associated with licensable status in respect of electricity
supply and distribution;
ii) The cost of standby and top – up (imported) electricity to decentralised
generators and the price offered by licensed suppliers for exported power;
iii) The arrangements with licensed electricity suppliers for the transport of
licence exempt electricity between decentralised energy sites;
•
There is an urgent need for reform of the electricity regulatory and licensing
system, so that medium size and larger decentralised energy schemes do not
have to participate in a market structure which is not designed for them, but at
the same time fully protecting consumers.
