Latest IPCC Findings. 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.

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.

Prioritising decentralised energy generation and renewables • Design to minimise CO2emissions 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

Barriers to Increased Decentralised Energy • There are serious market barriers which prevent decentralised energy from expandingto meetthe 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.
