London has an ambitious climate agenda1) Sadiq Khan elected in 2016 with a zero
carbon target by 2050
2) The London Environment Strategy is
London’s first integrated environment
strategy.
3) Ambitions include:
• Zero carbon city
• Zero waste city
• World Health Organisation PM2.5
targets for air quality
• Increase green cover to 50%
• Action plans for fuel poverty and
solar
• New funding to catalyse action
The challenge
1) London is a huge city, in area and
population.
2) Population is expected to grow to
over 11 million by 2050
3) 33 boroughs manage local services
including waste, roads and planning

Where we are now
1) London’s total energy has reduced
by over 20 per cent since 2000
2) Emissions have decreased by 32
per cent since 1990
3) Carbon intensity of UK electricity
has reduced by over 60 per cent
since 1990
4) Heat (natural gas) and transport
(diesel/petrol) remain key
challenges
1. Systemic actions
• Zero carbon buildings policy
• £750m to decarbonise public
transport
• Ultra Low Emission Zone
2. Leading by example
• Carbon budgets for functional bodies
• Responsible procurement
3. Direct delivery and interventions
• £34m Energy for Londoners
Programme
• Group solar buying scheme
• Cashback for clean boilers
4. Finance
• £500m energy efficiency
investment fund for public sector
and SMEs
• Catalyse investment in London’s
clean tech sector
5.Advocacy
• Calling for more action at a national
level
• Lobbying the government for more
power
Net zero carbon buildings
Current London Plan policy
• Net zero carbon homes policy introduced in 2016.
• On-site carbon savings maximised• Offsetting is allowed• Carbon offset price of £60/tonne• Heating hierarchy prioritises
district heat networks and CHP• Since Jan 2019 encouraging a roll
out of heat pumps in London by using more up to date carbon emission factors.
• Cooling hierarchy to manage heat risk
Net zero carbon buildings
New London Plan policy 2020
• Net zero carbon target extended to non-residential
• Introduces energy efficiency targets• Higher carbon offset price of
£95/tonne• Continues to prioritise connections to
district heat networks• Revised heating hierarchy places heat
pumps above gas-engine CHP, except where there are opportunities to facilitate district heating.
• New requirement for a whole life-cycle carbon assessment
• Introduces post-construction monitoring
• Cooling hierarchy to manage heat risk
Climate adaptation – it’s not just energy and carbon
Managing heat risk
• Reduce risk of overheating by following the Mayor ’s cooling
hierarchy
• Measures to consider include sensible glazing, external shading and
ensuring adequate ventilation
• Design for future weather projections
Green Infrastructure
• Urban Greening Factor (UGF)
• Quantify green infrastructure
• Green roofs
