The Woodland Trust has analysed the number of woods threatened by the HS2 project—33 ancient woods are under threat and 34 ancient woods are at risk within 200 metres of the proposed line. Given the threat posed by, say, climate change to the natural environment, not least to ancient woodland, the Woodland Trust also supports the move to develop a low-carbon economy. However, a transport solution that inflicts such serious damage on our natural heritage, as the current route does, can never really be described as green. The Government’s preferred routes for the phases of the scheme will cause loss or damage to at least 67 irreplaceable ancient woods. As the Woodland Trust has said to me, that is too high an environmental price to pay, and the route should be reconsidered in light of those facts alone.

A new line can help the UK to meet its 2050 carbon reduction targets under the Climate Change Act 2008 by attracting new passengers to the railways and by providing the additional capacity that freight and passenger services need. The rail freight sector has enjoyed 10 years of growth, and any Government that is serious about tackling carbon emissions would want to see that success continue. Without additional capacity, however, the risk is that freight operators will have to be turned away in future. Greengauge 21 looked at the environmental impact of the HS2 project last year, in a report commissioned by the Campaign to Protect Rural England, the Campaign for Better Transport and the Royal Society for the Protection of Birds. That report makes it clear that the environmental benefits of the new line have a close relationship with other policy areas.

The report also highlights the need for a full network as the carbon reduction benefits are multiplied fourfold when the second phase to Manchester and Leeds is factored in. The Government should and could have provided that certainty by introducing a single hybrid Bill to cover the entire route, allowing construction to start at both ends of the line. We need a clear timetable for decarbonisation of the electricity market, and that was one of the report’s recommendations. Labour has made a commitment to decarbonise the sector by 2030 before phase 2 of the new line is completed.

Network Rail has embarked on a major programme of electrification on our existing rail network, as well as on the new high-speed line. We need an ambitious timetable for decarbonisation to reduce the impact of that additional demand. There are steps that the Government could take now to maximise the environmental benefits of the new north-south rail line, However, those wider gains will not cancel out the loss of individual habitats. Loss in some areas may be unavoidable, but damage should take place only when all reasonable alternatives have been exhausted. The test is whether every reasonable step has been taken to mitigate environmental damage.

There is no doubt that there is a difficult balance to be struck. High-speed rail can help to deliver carbon reduction, which is why the Woodland Trust, the Campaign to Protect Rural England and Greenpeace support it in principle. Inaction is not an option, as road schemes and degraded air quality also threaten woodland. The line can bring real environmental benefits, but only if other policy decisions are taken, including in particular a commitment to decarbonise electricity. That wider context is crucial, especially as Parliament is being asked to confer extra spending and planning powers in aid of the scheme.
