Emissions
Viridor has introduced improvements to facilitate the accurate collection and reporting of its carbon emissions, which will in turn enable effective target setting and active management in this crucial area. This will also enable its obligations under the Carbon Reduction Commitment (CRC) to be met. The CRC has been implemented by the UK Government as a new climate change and energy saving scheme to promote energy efficiency and help reduce carbon emissions. Viridor has also fully engaged with its trade body, the ESA, to produce its carbon reporting protocol for the waste sector. Under this protocol, carbon reporting will include the following internationally recognised categories:
- Direct emissions resulting from an operator's activities (including both the processing and transport of waste)
- Indirect energy use emissions arising from an operator's purchase of electricity
- Avoided emissions resulting from a company's activities, including savings made by other sectors.

The principal greenhouse gases included in this reporting are CO2, CH4 (methane) and N2O (nitrous oxide). Viridor is committed to improving and refining its reporting of CO2 equivalents this year.
Within the UK, as well as providing a third of all renewable electricity, the waste management industry has been one of the most effective sectors in reducing greenhouse gas impacts. According to the UK Committee on Climate Change, the sector's emissions fell by 58% from 1990 to 2006. The Committee estimates 11% of further reductions should be achieved by 2020 by continued increased recovery of materials and energy from waste.
Viridor's total emissions for the year were calculated to be around 1.2 million tonnes as carbon dioxide equivalents. Over a million tonnes of which was directly related to landfill emissions. However the majority of this landfill gas was captured and used to create 504GWh of electricity, most of which was fed back into the national grid.

Data collated from the sectors' seven largest operators (including Viridor) shows carbon emissions of 8.8 million tonnes of carbon dioxide equivalent (mtCO2e) in 2008. However, about 5.3 mtCO2e were saved by these operators' activities (principally material recovery and generating renewable energy), suggesting net sector emissions of 3.5 mtCO2e.
The Company landfill emissions are reported through the Environment Agency's pollution inventory. Further improvements continue in the capture of landfill gas, a mixture of methane and carbon dioxide, brought about by a combination of a reduction in uncapped areas and early implementation of gas extraction.
With a fleet of more than 950 large goods and site vehicles in operation, engine emissions remain a key issue. There is continued need for waste and recyclates to travel significant distances to appropriate treatment or disposal sites, or to end markets. Logistical efficiencies are maximised for business benefits and emissions reduction. All new LGVs are fitted with lower emission Euro 5 engines. Part of the Viridor Transport Group remit is to identify areas where efficiency savings can be made which can be rolled out across the Company. Alternative transport arrangements, such as rail, that reduce emissions and congestion are also maximised, as is the case in the Greater Manchester contract where four rail heads will be utilised.
