I have taken some interventions and I will take some more, but first I want to make some points, particularly in response to the hon. Lady’s question. She asked about action, and that is legitimate. Let me be clear: in the UK, since 2010, we have decarbonised our economy faster than any other G20 nation; between 2010 and 2018, we reduced greenhouse gas emissions in this country by 25%; UK CO2 emissions have fallen for six years in a row, which is the longest period on record; and the UK’s renewable energy capacity has quadrupled since 2010. The proportion of UK electricity that comes from low-carbon sources increased from 19% in 2010 to almost 53% in 2018, which meant that 2018 was a record year for renewable energy; over the past year, we have generated record levels of solar and offshore wind energy; and annual support from the Government for renewables will be more than £10 billion by 2021. All that has come as a direct result of a shared ambition, with a Government who set stretching targets and are prepared to intervene where necessary, but who recognise that we need the ingenuity and enterprise of the private sector working in partnership with the Government to deliver change.
I stress that safeguarding our environment must not come at the cost of ending economic growth, because economic growth is vital to spur the innovation and secure the investment to make sure that we have the technological breakthroughs that can safeguard our environment. Since 1990, under Governments of different parties, we have seen a 40% overall reduction in greenhouse gas emissions, and we have also seen a two-thirds increase in growth. If we think in particular about the significant growth in renewables, of course solar energy initially needed subsidy to kick-start it, but as solar energy costs have diminished, so the need for subsidy is, as any economist would tell the House, lesser. This is no criticism of any previous Government, but when we came into power, only 38.3 MW of power in this country was generated by solar; now, the amount is 13,000 MW, which is 13 GW. That is a 99% increase in solar power generation under Conservative Ministers.
Now, is there more to do? I do not deny that there is more to do. Should we be more ambitious? We have to be more ambitious. The story is sometimes told of the past nine years as nine years in which we allowed the grass to grow under our feet; no, we allowed a thousand flowers to flourish to ensure that our environment was safeguarded.
