Environmental performance indicators
EN1 Material used by weight or volume
The range and complexity of our activities means it is not practical to report total materials used across our operations.
EN2 Percentage of materials used that are recycled input materials
Other than recycled consumables such as paper, plastic cups, etc., assumed to be zero.
EN3 Direct energy consumption
Energy use
Our energy use is dominated by our gas-fuelled compressors on our UK gas transmission network. Other major users of gas and electricity are our LNG sites and the Isle of Grain LNG import ...
EN4 Indirect energy consumption
Energy use
Our energy use is dominated by our gas-fuelled compressors on our UK gas transmission network. Other major users of gas and electricity are our LNG sites and the Isle of Grain LNG import ...
EN8 Total water withdrawn by source
Water use
This measures our performance in monitoring and reducing water used in both our non-operational properties and certain operational activities. Where possible, the data is collated through metered ...
EN9 Water sources significantly affected by withdrawal of water (add)
No water courses are significantly affected by the withdrawal of water for our operations.
EN10 Percentage and total volume of water recycled and reused (add)
The majority of extracted water is returned to source.
EN16 Total direct and indirect greenhouse gas emissions
Climate change
We have committed to reduce our own greenhouse gas emissions by 80% in advance of the target date of 2050 set by the UK Government. Against our baseline for continuing operations, to date we have ...
EN17 Other relevant greenhouse gas emissions
Scope 3 emissions and emission intensity
EN18 Initiatives to reduce greenhouse gas emissions and reductions achieved (add)
Profits through responsible environmental management
A safe, reliable and efficient supply of energy is essential for economic growth and for the quality of life of us all. Delivering such secure supplies while taking reasonable and practical steps to ...
EN20 NO, SO and other significant air emissions
NOx and SOx emissions
Our material emissions of Nox and Sox arise directly from our compressor fleet installed on our gas transmission network and our liquefied natural gas facilities in the UK.
EN22 Total weight of waste by type and disposal method
Waste
During 2007/08, we generated some 1.1 million tonnes (119 tonnes per £million of revenue*) of waste compared with some 1.2 million tonnes (142 tonnes per £million of revenue) for 2006/07. ...
EN23 Total number and volume of significant spills
Our environmental incident reporting includes, but is not limited to, spills.
EN27 Percentage of products sold and their packaging materials that are reclaimed by category
Not applicable to our operations as "product" is primarily the transportation of electricity and gas.
EN28 Monetary value of significant fines and total number of non-monetary sanctions for non-compliance with environmental laws and regulations
Environmental incidents
The number of significant environmental incidents in 2007/08 arising directly from our operations was 34, which included 25 contractor related incidents, compared with 40, including 20 contractor ...
