Annual sustainability report 2013-14: Covering paper
The detailed annual sustainability report for 2013-14 is appended to this covering paper, this
presents a summary of carbon emissions performance from April 2008 to March 2014, based on
all building carbon emissions where Moorfields is responsible for the procurement of energy.
The carbon target represents a 10% reduction in carbon emissions over the 5-years from the
baseline year of 2008/09 to 2014/15; our performance at the end of the 4th year is shown below:
•
Absolute carbon emissions have decreased by 1% from 5,456 tCO2 to 5,386 tCO2;
•
Emissions from electricity have reduced by 3%, those from gas have increased by 2%;
•
Emissions from City Road, the asset responsible for most carbon emissions, have
decreased by 4%, whilst those from the RDCEC have increased by 21%.
The detailed report presents the energy efficiency measures delivered over the past 4 years,
and demonstrates that the increase in patient activity has been delivered with minimal impact on
our carbon emissions, i.e. our carbon emissions per patient have reduced by approximately
29%. This has been achieved despite the continuing growth in the intensity of use of the estate,
both in terms of occupancy and extended working hours, additional diagnostic equipment, and
the delivery of the new data centre in the RDCEC (a key component of our IT business
continuity plans).
Based on the above information, we will not achieve the 10% saving in the final scheme year;
however a key planned efficiency relating to voltage optimisation will have a significant impact
on our emissions and may enable us to meet the target at the end of 2015/16. There are no
financial consequences for not achieving the target, over and above the continued purchase of
carbon allowances. The reputational impact of non-achievement should be minimised by our
over-achievement in reducing emissions per patient, and the reality that the national
performance lists are no longer published.
As participants in the Carbon Reduction Commitment we are required to purchase carbon
allowances at £12 per tonne. We emitted 5,625 tonnes1 in 2013/14 and this equates to £67,500
in allowance purchases – in line with planned expenditure and a saving of £2,700 against the
previous year.
Carbon allowances will increase to £16.40 per tonne for the 2014/15 scheme year, if we were to
maintain our current emission levels this would equate to a cost £92,250.
Trust Board Recommendation
The Board is asked to note:
1. The annual sustainability report and our current performance against the 10% target, in
the context of additional patient activity and intensity of use.
2. The underlying carbon emission reduction of approximately 29% per patient.
3. The further plans to improve energy efficiency through voltage optimisation.

Government mandates that organisations use different carbon emissions for CRC reporting therefore CRC
emissions factors are higher than the factors used for company reporting, hence the difference between the two
figures. Government has now recognised this discrepancy and from next year the two reporting process will be
aligned and the figure will be more comparable.

Carbon Emissions - Performance
This annual report provides a summary of carbon emissions performance from April 2008 to March
2014 based on all building carbon emissions where Moorfields Eye Hospital NHS Foundation Trust is
responsible for the procurement of energy.
This includes the following sites:
• Moorfields Eye Hospital, City Road;
• Moorfields Pharmaceutical;
• Richard Desmond Children’s Eye Centre;
• Ebenezer Street;
• Provost Street;
• 8 Wimpole Street;
• Arthur Steele Unit;
• St Anne’s.
The key messages from this report are highlighted below:
When comparing financial year 2008/09 and financial year 2013/14:
• Absolute carbon emissions have decreased by 1% from 5,456tCO2 to 5,386tCO2;
• Carbon emissions from electricity consumption have decreased by 3%;
• Carbon emissions from natural gas have increased by 2%;
• Emissions at Moorfields Eye Hospital, City Road, the asset responsible for most carbon
emissions, have decreased by 4%;
• Emissions at the Richard Desmond Eye Centre have increased by 21% over this time period.
Detailed explanation of these results is provided over the following pages.

2013/14 Sustainability Report
1.1 Absolute Carbon Emissions
Absolute carbon emissions refer to the total amount of carbon emitted through the consumption of
energy across all buildings where Moorfields Eye Hospital NHS Foundation Trust is responsible for
the procurement of energy. The reason why carbon emissions are measured on this basis is that this
directly links to the requirements of the Carbon Reduction Commitment legislation (see
Compliance Section) as well as NHS Sustainable Development Unit and Climate Change Act targets.
In order to calculate carbon emissions, Moorfields utilises industry standards including the
Greenhouse Gas Protocol and DEFRA Guidance to report emissions from scope 1, 2 and 3 sources.
These reporting scopes are explained below:
• Scope 1 emissions: direct greenhouse gas emissions occurring from sources owned or
controlled by the Trust. For example the combustion of natural gas in boilers;
• Scope 2 emissions: greenhouse gas emissions from the off-site generation of grid electricity;
• Scope 3 emissions: all other indirect emissions, which are the consequence of the Trust’s
activities but occur from sources not owned or operated by the Trust. For example grid loses
from the transportation and distribution of electricity.
In order to contribute towards national carbon mitigation targets set by both Government and the
NHS Sustainable Development Unit, Moorfields has set the following carbon reduction target:
Moorfields Eye Hospital NHS Foundation Trust will reduce absolute carbon emissions by 10% by
the end of financial year 2014/15 based on a 2008/09 baseline.
The following figures and tables illustrate the Trust’s progress to date:

As the figure and table above demonstrate, absolute carbon emissions have decreased from
5,456tCO2 to 5,386tCO2 (1%) when comparing 2008/09 with the same period in 2013/14. This
therefore shows that, at present, Moorfields is not on track to achieve its carbon emissions target.
The relatively small reduction has been achieved primarily due to a 3% reduction in electricity
consumption. In contrast, carbon emissions from the combustion of natural gas have increased 2%.
In the half year Sustainability Report, emissions were reported as 8% below the April-September
2008 baseline level. This was encouraging and suggested that the carbon emissions reduction target
would be achieved. However, it was noted at the time that emissions were expected to increase
during the remainder of the year as the Combined Heat and Power (CHP) engines were switched off
to undergo maintenance. Whilst this led to the slight benefit of reducing natural gas consumption,
electricity consumption increased markedly. This can be clearly seen in the figure below, where from
February to early April an increase in average daily half hourly electricity consumption can be seen.
From early April electricity consumption returned to normal operating levels. It is expected that this
should continue for the rest of the year.
By using the CHP consumption figures for the same time period in 2012/13 it can be calculated that a
6.4% saving would have been achieved when comparing 2008/09 with 2013/4. This would have put
the Trust far closer to the reduction target going in to the last year of the target period.

2013/14 Sustainability Report
(a) Carbon emissions by asset
7
2013/14 Sustainability Report
These demonstrate that Moorfields Eye Hospital, City Road was responsible for 66% of total building
emissions during 2013/14 and is therefore the largest contributor to the absolute carbon footprint.
Emissions at this asset have decreased 4% when comparing 2008/09 and 2013/14. A number of
energy efficiency measures have been implemented at this site over the past 2 years which have
contributed to reduction in emissions here. See the “Carbon Emissions - Mitigation” section for further
details. It is expected that this reduction will increase over the next financial year as the CHP engine
has returned to normal operating levels.
Moorfields Pharmaceutical is the second largest emitter of carbon in the Trust’s estate portfolio. The
second figure illustrates that carbon emissions have remained broadly similar over the past 6 years
with a relatively minor 0.4% decrease when comparing 2008/09 and 2013/14.
Following the installation of a data centre and associated plant (including a new chiller) at the Richard
Desmond Eye Centre, carbon emissions increased 21%. However, no further major mechanical and
electrical system installations are planned for this site in the near future. If emissions had remained
static at this asset, a 3% reduction target across the whole organisation would be achieved when
comparing absolute emissions between 2008/09 and 2013/14.
1.2 Relative Carbon Emissions
Relative carbon emissions are used to understand how Moorfields Eye Hospital NHS Foundation
Trust emits carbon relative to its functions as a specialist healthcare organisation. To do this absolute
carbon emissions are scrutinized against two intensity factors, £million revenue and patient activity
numbers, in order to understand how carbon emissions change as business functions change.
Relative carbon emissions Apr-Sep 2008 to Apr –Sep 2013 - £million revenue
8
2013/14 Sustainability Report
Relative carbon emissions Apr-Sep 2008 to Apr-Sep 2013 – patient activity
These figures both demonstrate that despite substantial increases in £million revenue and patient
activity numbers, relative carbon emissions have decreased by 35% and 23% respectively. This
therefore illustrates that the Trust is operating in a more energy efficient manner.
The principle reason that absolute carbon emissions have not reduced more over the past 6 years is
that the Trust’s business activities, as highlighted above, have rapidly increased.
For example, patient activity has grown by 29% when comparing 2008/09 and 2013/14. This in turn
has resulted in increased carbon emissions as increased patient demand has driven increased
energy consumption. Any savings made through energy conservation measure projects have been
partly negated as a result of this.
If patient carbon intensities had remained at the same rate as 2008/09, absolute carbon emissions in
2013/14 would have been 7,020 tCO2. When comparing this figure with the actual performance of
5,386 tCO2 in 2013/14 it can be inferred that carbon mitigation measures have resulted in the
avoidance of 1,634 tCO2, a 29%reduction.

2013/14 Sustainability Report
Carbon Emissions - Mitigation
Previously the status of installed energy efficiency measures was provided verbally by the
Maintenance Manager. However, the Energy Engineer is now in the process of undertaking detailed
surveys of previous energy saving measures and providing full reports on each activity to both
confirm level of savings achieved as well as highlighting any potential future opportunities.
Future planned activities are shown below.
It is anticipated that these actions should ensure the required reduction in absolute carbon emissions,
assuming no changes to business functions e.g. an increase in patient activity numbers or the
installation of energy intensive equipment. A further detailed analysis will be provided over the
coming months.

Waste – Performance
The table below gives an overview of our waste volumes and segregations percentages.
Facilities previously benchmarked Moorfields with all NHS hospitals across the UK using the ERIC
data for 2012 – 2013. The data showed that Moorfields were currently placed 38 out of 294 hospitals
with regards to the percentage of waste being diverted from Landfill.
Waste volumes – April 2013 to March 2014
Waste Weights
83,084, 16%
22,401, 4%
Landfill
Reused/Recycled
HT incineration with recovery
421,738, 80%
Whilst we are placed 38 within the UK out of 294 hospitals there are other considerations that need to
be understood. A large percentage of the other 37 Hospitals incinerate most of their waste. This is
not the best disposal route as stated by the EA with the waste hierarchy. If we take the incineration
process into consideration then we would indicatively be place within the top ten hospitals within the
UK on waste performance. Please note that this information was benchmarked against 2012 – 2013
as the most current ERIC reports have not been released online as of yet.
Compliance
Carbon Reduction Commitment
As participants in the Carbon Reduction Commitment Moorfields Eye Hospital NHS Foundation Trust
is required to measure, monitor and disclose carbon emissions from all electricity and certain gas
supplies to the Environment Agency where the Trust is responsible for the procurement of energy.
When carbon emissions have been ascertained, an allowance for each tonne of carbon must be
purchased and surrendered at a cost of £12/tonne. This cost is due to increase to £16.4 for the next
scheme year (2014/15).
13
2013/14 Sustainability Report
During the 2013/14 period 5,625 tonnes of carbon covered by the scheme have been emitted. This
equates to £67,500 in allowance purchases. When compared to the previous scheme year,
emissions covered by the CRC have reduced by 225 tonnes. This represents a saving of £2,700 in
reduced allowance purchase requirements.
(a) Carbon Reduction Commitment – External Audit
In order to avoid financial penalties associated with noncompliance, an external audit has been
carried out covering Moorfields participation in the first four years of the scheme. Following this audit,
where participation was independently checked and assured, the Trust can confirm that it is
compliant in all areas of the scheme including areas of best practice.
Display Energy Certificates
Buildings occupied by a public authority where the total useful floor area of the building exceeds
500m2, and which is frequently visited by the public, are legally required to have a Display Energy
Certificate (DEC). The aim of these are to provide an energy rating of a building from A to G, where A
is very efficient and G is the least efficient based on the amount of metered energy used by the
building. These must be updated on an annual basis.
At present Moorfields is required to have two Display Energy Certificates - one for Moorfields Eye
Hospital, City Road, the other for the Richard Desmond Eye Centre. The most recent Display Energy
Certificates are shown below. Despite each A-G rating remaining the same as previous certificates,
Moorfields Eye Hospital, City Road has shown an improvement with a score of 132 as opposed to
136 in the previous year. In contrast, performance at the Richard Desmond Eye Centre, for reasons
mentioned in the “Carbon Emissions - Performance” Section, has slipped with a score of 113
compared to 106 last year.
