Net-zero Carbon Emissions: Behaviour Change — House of Lords, 2021-09-16
Topic: Environment
Jennifer Elizabeth Randerson (Liberal Democrats, Centre to centre-left): My Lords, I start by thanking the noble Baroness for bringing this topic to the Chamber this afternoon and for her excellent speech Up to now, most of the adaptations and changes required to reduce carbon emissions have been done to us, or for us, by the Government or have been as a result of business decisions. For example, all the changes in the means of production for energy have been done for us. We have hardly been aware of those changes—unless, of course, like me, noble Lords have solar panels on their roof. Only now are we starting to get to the more difficult bits, such as starting to change how we heat our homes There are exceptions. For example, we have adapted to paying for plastic bags; as a result, we use far fewer of them. Most of us could talk at length about local recycling schemes, the differences between them and the benefits of some of them. However, the lessons of those two examples are that it takes a long time to bed in change in our behaviour. We face a climate emergency. The big question is: is 2050 early enough for net zero? There is real doubt about that. The answer? Probably not. The longer it takes to start, the more radical the changes must be In the time I have, I will concentrate on transport because it is the single biggest sector for CO2 emissions. It is also the only sector where, in recent decades, emissions have not fallen despite technological improvements. Earlier this summer, the Government produced a welcome transport decarbonisation plan. Unfortunately, it started with a complete fallacy. It said that we can carry on doing everything we currently do and that technology will make the changes we need to reach net zero. This argument was even applied to aviation The problem with transport is that we all want to travel more, not less. The pandemic has given us pause for thought and demonstrated that a lot of our travel can be avoided. During the pandemic, there was a lot of talk about finding new, healthy and environmentally friendly ways in which to live and work. Now that the Government think the pandemic is over, their rhetoric has immediately pressed us to get back to the office despite the fact that we have demonstrated that we can do a great deal of work without being in the office. Fortunately, many employers and employees are resisting this, but trains, the Tube and buses are crowded again and our roads are very congested, with traffic volumes up to and beyond pre-pandemic levels because people are now reluctant to use public transport. We were beginning to see the switch to public transport, but that has regressed There is a saying: "Never waste a crisis." The danger is that the Government will waste this one by not seizing the moment and not capitalising on the pause that the pandemic created. There is every reason to review, for example, business travel because Zoom can do much of it without the same waste of time or CO2. There are major opportunities for change, but we are also at a dangerous point because we are no longer bound to the EU where the rules have set world standards for so long. We must not allow ourselves to slide back from that Specifically, there is the problem of time lag. Vehicles manufactured today will still be on our roads in 20 years’ time. The time lag is even greater for buses, planes and ships. The Government need to influence what we buy and use now. We are buying enormous modern SUVs. The Government also need to influence how we drive them. We need information so that we understand all the implications of our behaviour. All social revolution needs this; it needed it for drink-driving, seatbelt-wearing and smoking. We must have government information backed up with regulations to give us a nudge. We need taxation to encourage us not to buy SUVs, to ensure that aviation tax is reformed and to discourage frequent flyers. We need regulation change; for example, to encourage us to drive more slowly We face an emergency, and emergencies require urgency. The rain is falling on the ice caps now. Belgium as well as Bangladesh face people dying in flash floods. It is not enough to plan for tomorrow. The Government need to plan for today, utilise the expertise of our universities, our scientists and throughout the Civil Service, and ensure that we have an effective public debate.
