Starting with the targets themselves, I'd like to take each of these in turn. The Climate Change Commission says that our climate change targets are achievable and can be met with existing technology, but only if we act now. Over the last 3½ years, this Government has laid the foundations from which the commission is now asking us to build. This will help to ensure a sustained decline in the pollution that we put into the atmosphere, and it will mean future Governments can ensure that this decline continues and, in fact, picks up pace every year until we hit net zero.
