June 2012: The London Datastore has recently posted a spreadsheet containing the data behind the Mayor’s climate change mitigation and energy strategy, which was published in October 2011. This is particularly useful as the strategy provided graphical projections of the predicted savings of the Mayor’s various carbon-reduction programmes, but not ‘hard numbers’. Tab 6b of the spreadsheet sets these out, and some of the key programmes are summarised below:
Emissions Savings [MtCO2/yr] of committed Mayoral actions:
| 2010 | 2011 | 2012 | 2013 | 2014 | |
| RE:NEW | 0.0103 | 0.0207 | 0.0310 | 0.2300 | 0.4290 |
| Low Carbon Zones | 0.0009 | 0.0036 | 0.0061 | 0.0061 | 0.0061 |
| New Build through planning (domestic) | 0.1501 | 0.1501 | 0.1501 | 0.0869 | 0.0869 |
| RE:FIT | 0.0012 | 0.0061 | 0.0133 | 0.0217 | 0.0303 |
| Better Buildings Partnership | 0.0000 | 0.0050 | 0.0050 | 0.0050 | 0.0050 |
| ERDF* | 0.0053 | 0.0089 | 0.0089 | 0.0089 | 0.0089 |
| LDA Energy Efficiency Revolving Fund | 0.0000 | 0.0000 | 0.0004 | 0.0004 | 0.0004 |
| New Build through Planning (non-domestic) | 0.2042 | 0.2042 | 0.2042 | 0.1182 | 0.1182 |
*ERDF refers to the funding received by London government through the European Regional Development Fund, which helps fund – amongst other things – the London Green Fund. Further information here.
The Mayor has not as yet reported on savings achieved by his programmes (ie for the years 2010/11 and 2011/12) but Chapter 10 of the Mayor’s energy strategy sets out that these will forthcoming through two actions:
• Action 17.1 – The Mayor will continue to publish the London Energy and Greenhouse Gas Inventory (LEGGI) online every year (the latest dataset is for 2008, published in September 2010)
• Action 17.2 – The Mayor will produce an annual report on London’s progress on meeting its CO2 emissions reduction targets, including annual estimated CO2 emissions, and progress on Mayoral climate change mitigation programmes.
