Footnotes to ‘Climate leadership: UK and US compared’
Climate targets
The US has a target of 17% reduction compared with a 2005 baseline, which has been converted into a 1990 baseline to enable comparison with the UK’s Kyoto commitments. See Frank Jotzo, Comparing the Copenhagen emissions targets, page 9, available from 

Carbon emissions
Comparative US and UK carbon dioxide emissions were drawn from the BP Statistical Review of World Energy June 2014: Historical data workbook. Available from 
Population figures are from the US Census Bureau International Data Base, revised December 19, 2013. Version: Data:12.0625 Code:12.0321. Available from 

Renewables investment
The figures were calculated based on data from the sources listed below. The data for all years except 2010 and 2008 were adjusted for reinvested equity.

Leadership on new coal
On 20th September 2013, the US EPA proposed carbon pollution standards which effectively prevent new unabated coal: 
In 2009, the UK government announced that carbon capture and storage would be required for new coal power plants: 

Renewables RD&D 
The data are taken from IEA Energy RD&D Statistics; RD&D Budget. Calculations are based on 2012 $, and 2010 population figures. The data were extracted on 12 Aug 2014 from the OECD iLibrary: 

Cutting coal emissions
The EPA’s analysis shows that under the proposed rules (Option 1), coal plants will produce about a quarter less power, and 1 in 5 coal plants will shut. Technically, this is 1/5 of installed capacity, which could mean a disproportionate number of small power plants shut. See Table 3-12 in EPA, Regulatory Impact Analysis for the Proposed Carbon Pollution Guidelines for Existing Power Plants and Emission Standards for Modified and Reconstructed Power Plants, June 2014, available from 
In the UK, MPs voted in 2013 not to limit emissions from existing coal-fired power stations: 

Climate statements
These numbers only include statements since 2010, when the current UK government came to power, so that the comparison is over an equal time period.

The UK Prime Minister spoke at the UN Climate Summit in September 2014: 

The US President launched his climate action plan with a speech at Georgetown in June 2013:

And he focused on climate change in a speech to UC Irvine in June 2014:

President Obama then spoke at the UN Climate Summit in September 2014: 

President Obama also gave a speech on climate change to the UN in September 2009, which is not included in our calculation: 

The UK Foreign Secretary has given one speech on climate change: and has made four press statements: 

The US Secretary of State’s remarks on climate change are listed here: 

Secretary of State John Kerry wrote an op-ed in ThinkProgress in July 2013: 

As Secretary of State, Hillary Clinton also gave two speeches, a Time Magazine interview, and wrote an op-ed about the Clean Cookstoves initiative, which all mention climate change. However, these have been excluded them from the figures presented above, because the focus of those comments was predominantly on health and women’s rights.
