How did we do?
We have continued to improve the scope of our data capture. Our results year-on-year are as follows:
Useable floor space
Our useable floor space per employee decreased from 13.8 m2 to 12.5
m2 year-on-year primarily as a result of the Refco integration. Restricting
the analysis to the same offices as last year results in a comparable,
like-for-like, measurement of 13.6 m2 per employee.
CO2 emission per square metre
Overall CO2 emissions per square metre resulting from our utility usage
fell 38%, reflecting the reductions generated by our London energy programme.
Water usage
Our water usage fell from 19,403 litres to 10,872 litres per employee,
44% down on a like-for-like basis against last year. Previously, our
data related to the London office only, that includes a staff restaurant
facility. While many of our overseas offices are tenants in a larger
multi-tenant building where usage is not individually metered, the 2007
figure represents improved data quality. The comparative usage for London
only is 16,624 litres per employee.
Gas usage
Our gas consumption fell from 2,582 kWh per employee to 1,005 kWh per
employee year-on-year. Previously the data was based on usage in the
London office only, but the valuation now reflects many of the overseas
offices that predominantly do not use gas, with the exception of Switzerland.
The comparable gas usage for London only in 2007 shows a reduction to
2,256 kWh per employee, 13% down year-on-year.
Electricity usage
Our electricity consumption fell year-on-year from 7,680 kWh to 5,812
kWh per employee. Again the reduction reflects the improved reach of
our data capture to more overseas offices. However our historic data
is based on our major offices and IT centres in London, Switzerland
and the US, which continue to require more power.
CO2 emissions per employee
Our CO2 emissions continued to fall year-on-year, from 3,716 kgCO2 to
2,688 kgCO2 per employee, reflecting the benefits of ‘green’ tariff
supply at our London sites, this despite a marginal 4% rise in CO2 emissions
from air travel.
In compiling the analysis we used the CO2 emission conversion factors issued by Department of Environment Food and Rural Affairs (DEFRA) Guidelines for Company Reporting on Greenhouse Gas Emissions – July 2005 and the United Nations Conference on Trade and Development (UNCTAD) standard emissions factors. The reductions exceeded our internal target of a 3% reduction year-on-year.
Video conferencing
The number of video conference units (rooms with video conferencing
facilities or portable units), which help reduce the need for business
travel, increased 36% year-on-year.
The breakdown of our recycled waste is as follows:
| Tonnes | Plastic | Paper | Cans | Cardboard | Glass | Food | Mixed |
| 2006 | 2 | 15 | 4 | – | 1 | – | – |
| 2007 | 3 | 14 | 1 | 24 | 7 | 7 | 21 |
Waste management and recycling
The amount of waste we recycled in our London offices this year more
than tripled, from 22.40 tonnes last year to 76.80 tonnes this year,
and we have been able also to introduce programmes in Dubai, Dublin,
Hong Kong and Chicago.
We have received undertakings from building managers of some of the offices where we are not the sole occupier, that recycling programmes will be introduced. We hope to update on progress on the Corporate Responsibility website over the coming year.
We have also now added cardboard and food to the list of waste recycled.
Accreditation
Our Carbon Programme has been accredited by the firm Virtuous Circle
Ltd. Full details can be found in our separate Corporate Responsibility
