Energy Security and Net Zero – in the House of Commons at on 10 February 2026.

If he will update the UK emissions trading scheme to reflect the carbon abatement costs of major projects.

The carbon pricing emissions trading scheme is set by the market, rather than the Government. The price is effective at driving investment in carbon abatement measures, but it is for individual operators to decide whether the costs of abatement in a project are effective for them.
Sarah Olney
Liberal Democrat Spokesperson (Business)
Last week the Government updated their carbon values to reflect their latest net zero emission target, but the UK emissions trading scheme does not take into account the updated figures. In 2021, it was predicted that carbon abatement for a third runway at Heathrow would cost £100 million, and costs will have only risen since. According to the emissions trading scheme, just 15% of the clean-up costs of expansion will be covered by Heathrow; the rest will fall on the taxpayer. Will the Minister update the UK emissions trading scheme to reflect the carbon abatement costs of major projects such as Heathrow expansion, so that the taxpayer can understand how much they will have to pay for a third runway?

The Government do not comment on or interfere with the carbon price. Ultimately, the price is set by the market to ensure that the ETS drives decarbonisation where it is cheapest. In this way, it can act most effectively as a financial incentive to decarbonise, without specifying the particular technology.

I call the Shadow Secretary of State.
Claire Coutinho
Shadow Secretary of State for Energy Security and Net Zero, Shadow Minister (Equalities)
Thank you, Mr Speaker, and it is great to see you back on your feet.
Last week, the Labour party voted to increase the carbon tax, which increases costs for households and industry, and those costs have already doubled because of its policies. It is absolutely shameful for the Government to say that they have had no impact on the carbon tax whatsoever. It now accounts for over 10% of household electricity Bills, and the rise is in effect a £5 billion a year tax on the British economy. Can the Minister explain why the Labour party wants to tax our industrial jobs out of existence, leaving Britain reliant on dirtier imports from abroad?

I am not sure if the Shadow Secretary of State is conflating the various carbon taxes with the emissions trading scheme, but to be clear: the Government do not set or comment on the value of the carbon in the emissions trading scheme. That is a matter for the market. It is of course a policy on which the previous Government were very keen, because it drives the most efficient forms of decarbonisation. Ultimately, it places a price on carbon emissions that ensures private capital floods into the right places to decarbonise, as we have seen so successfully with the power sector in the UK.
Ministers make up the Government and almost all are members of the House of Lords or the House of Commons. There are three main types of Minister. Departmental Ministers are in charge of Government Departments. The Government is divided into different Departments which have responsibilities for different areas. For example the Treasury is in charge of Government spending. Departmental Ministers in the Cabinet are generally called 'Secretary of State' but some have special titles such as Chancellor of the Exchequer. Ministers of State and Junior Ministers assist the ministers in charge of the department. They normally have responsibility for a particular area within the department and are sometimes given a title that reflects this - for example Minister of Transport.
Secretary of State was originally the title given to the two officials who conducted the Royal Correspondence under Elizabeth I. Now it is the title held by some of the more important Government Ministers, for example the Secretary of State for Foreign Affairs.
The shadow cabinet is the name given to the group of senior members from the chief opposition party who would form the cabinet if they were to come to power after a General Election. Each member of the shadow cabinet is allocated responsibility for `shadowing' the work of one of the members of the real cabinet.
The Party Leader assigns specific portfolios according to the ability, seniority and popularity of the shadow cabinet's members.
A proposal for new legislation that is debated by Parliament.
The Speaker is an MP who has been elected to act as Chairman during debates in the House of Commons. He or she is responsible for ensuring that the rules laid down by the House for the carrying out of its business are observed. It is the Speaker who calls MPs to speak, and maintains order in the House. He or she acts as the House's representative in its relations with outside bodies and the other elements of Parliament such as the Lords and the Monarch. The Speaker is also responsible for protecting the interests of minorities in the House. He or she must ensure that the holders of an opinion, however unpopular, are allowed to put across their view without undue obstruction. It is also the Speaker who reprimands, on behalf of the House, an MP brought to the Bar of the House. In the case of disobedience the Speaker can 'name' an MP which results in their suspension from the House for a period. The Speaker must be impartial in all matters. He or she is elected by MPs in the House of Commons but then ceases to be involved in party politics. All sides in the House rely on the Speaker's disinterest. Even after retirement a former Speaker will not take part in political issues. Taking on the office means losing close contact with old colleagues and keeping apart from all groups and interests, even avoiding using the House of Commons dining rooms or bars. The Speaker continues as a Member of Parliament dealing with constituent's letters and problems. By tradition other candidates from the major parties do not contest the Speaker's seat at a General Election. The Speakership dates back to 1377 when Sir Thomas Hungerford was appointed to the role. The title Speaker comes from the fact that the Speaker was the official spokesman of the House of Commons to the Monarch. In the early years of the office, several Speakers suffered violent deaths when they presented unwelcome news to the King.
