My Lords, I thank the noble Baroness for expressing once again the reasoning behind her amendment. I also recognise the contribution from my noble friend Lord Deben. However, I fear that I cannot accept the amendment. I urge noble Lords to consider the positive work that this Government have already set in train to address the underlying general environmental concerns. Indeed, earlier this afternoon, on an environmental supplementary duty in respect of the CAA’s airport economic regulation functions, I referred to some examples of the action taken by this Government to ensure that the sector makes a significant and cost-effective contribution to mitigate the adverse environmental effects of civil aviation in the UK. I also urge your Lordships to consider the merits of the amendments we have already agreed to address the specific concern of the impact of the airport economic regulatory regime on the environment.
Let me now address this amendment, which seeks to provide the CAA with a general environmental duty. The previous Government consulted on giving the CAA a general environmental objective, alongside proposed safety and consumer objectives, in December 2009. The responses were mixed, with airport operators in favour but airlines opposed. The majority of airline respondents felt that it was for the Government to set the direction of environmental policy but for the CAA to regulate, and that giving the CAA an environmental objective would blur the boundary between policy and regulation and could create additional costs on the industry. They felt that it was not appropriate for the CAA to have to make environmental judgments on noise or emission levels at airports but instead that it was more appropriate for it to regulate the impacts in line with government environmental policy. We talked earlier about the difficult policy issue of Heathrow Airport, the background to which is of course an environmental issue regarding what the environment can tolerate. However, these issues are a matter for central Government.
Since the consultation, the CAA has included an objective in its Strategic Plan: 2011 to 2016:
“To improve environmental performance through more efficient use of airspace and make an efficient contribution to reducing the aviation industry's environmental impacts”.
I will come back to that in a little more detail in a moment. Additionally, the information, guidance and advice duties and powers in the Bill are now stronger than those that were consulted on. The CAA has a duty to secure publication of appropriate environmental information. Environmental impacts have been defined very broadly in Clause 84 to include noise, vibration, emissions and visual disturbance from aircraft as well as the “effects from services” and facilities “provided at civil airports”.
The knock-on consequences for human health are also covered by the information provisions in Clause 84. This is a very important issue for some communities and one where additional information could provide a valuable contribution to an informed debate. Noble Lords should be in no doubt that there are real benefits to be gained through the collection of good quality environmental information that can be presented in a consistent way to help passengers and freight owners judge the environmental impact of their travel choices. In addition, the CAA will be able to publish guidance and advice with a view to the sector limiting or controlling the adverse environmental effects of civil aviation in the UK. I suspect that the environmental effect that most concerns the noble Baroness is that of CO2 emissions.
The CAA is also already undertaking and supporting a number of actions to deliver positive environmental outcomes. Two examples of that include, first, the CAA’s work on implementing the Single European Sky initiative to enhance the design, management and regulation of airspace across the EU by moving from airspace divided by national airspace boundaries to functional airspace blocks. It is estimated that since 2008, the UK-Ireland functional airspace block has provided approximately £35 million of savings, including around 150,000 tonnes of CO2. Under the EU’s Single European Sky legislation, the environment is considered to be as important as safety and efficiency and there
are EU-wide performance targets on the environment. The CAA has reflected this additional emphasis on the environment in its regulatory approach to the provision of air traffic management services.
Secondly, the CAA is also continuing to develop and take forward the future airspace strategy to modernise the UK airspace system. Again, I have organised a presentation for your Lordships to understand the work that is going on. This includes a clear driver to implement air traffic management improvements that reduce emissions from aircraft and contribute to minimising aviation’s environmental impact. These include enabling more direct routes and optimal vertical profiles, continuous climb and descent procedures and reduced reliance on stack holding, which all reduce greenhouse gas emissions. Both these developments will be positive for CO2
emissions; indeed, that is one of the drivers for them. I hope that the House will agree that we have struck a good balance on the environment, since we have already agreed some useful amendments today, and that the CAA will be better placed than ever before to take environmental matters very seriously, as we would expect it to do. I hope that in due course the noble Baroness will withdraw her amendment.
