DECC RESPONSE TO EAC QUESTIONS ON THE LOW CARBON TRANSITION PLAN[8]

1.  Why is the carbon budget for 2008-12 of 3018 MtCO2e (Table 1, p39) higher than the "emissions before policies" baseline of 2964 MtCO2e for the period 2018-22 (Chart 3, p43)?

  The "emissions before policies" baseline does not represent business as usual. It reflects a projection of UK emissions before any estimated emission savings from Low Carbon Transition Plan policies, but does include emission savings from previously existing firm and funded policies—such as those in the 2006 Climate Change Programme (see Tables A1 and A5). Due to these pre-existing measures, UK emissions are projected to be falling across the carbon budget periods in the baseline, albeit at a much lower rate than when the Transition Plan policies are included, and so "emissions before policies" are lower in 2018-22 than our carbon budget for 2008-12. Chart 1 (p6) allows a comparison of both baseline (top line, before sectoral reductions) and Transition Plan (bottom line, after sectoral reductions) emissions projections.

2.  How can the 248 MtCO2e total emissions savings for the traded sector (EU ETS) in 2018-22 reported in Table A4 (p202) be reconciled with the data in Tables A5 and A6?

Table A4 presents the projected emission savings from policies in the Transition Plan by carbon budget period on a net UK carbon account basis. The total savings in the sectors covered by the EU ETS (the traded sector) are reported to be 248 MtCO2e in 2018-22—based on the UK's share of the EU ETS cap given compliance with the EU ETS ensures that this is equal to the level of UK domestic emissions net of any sales and purchases of carbon units.

Table A6 lists the UK domestic emissions savings from Transition Plan policies in the traded sector, disaggregated by the economic sector in which the measures are implemented. The total traded domestic savings amount to 267.2MtCO2e in 2018-22. This is higher than the savings assigned on a net UK carbon account basis (the EU ETS cap), and the difference of 19 MtCO2e represents the number of allowances that would be available for sale by UK operators. The second to last row in Table A9 (p213) presents the annual projection of net sales or purchases through the EU ETS. (Any difference between the figures in Table A9, and the inferred purchase and sale figures from tables A4 and A6 are due to the rounding of figures.) Chart A3 (p214) provides a graphical illustration of the expected levels of net sales or purchases through the EU ETS by plotting projections of the net UK carbon account and actual domestic emissions against each other.

Table A5 reflects policies that are already included in the baseline, and does not relate to the reported savings in Table A4. The reference to Table A5 in Table A4 is therefore an error and should be ignored.

3.  Why are all savings from the traded sector ascribed in Chart Al (p196) to Power & Heavy Industry, when according to Table A6 (p202) savings will also arise in Homes & Communities and Workplaces & Jobs?

  The Transition Plan policies implemented in the Homes & Communities and Workplaces & Job sectors that are listed in Table A6 generate savings by reducing electricity demand, resulting in lower emissions from power generation. These savings are therefore assigned, for the purposes of Chart A1, to the Power and Heavy Industry sectors (the traded sector). The savings in Power & Heavy Industry are then corrected so that they correspond to the level of the UK's share of the EU ETS cap.

4.  Why are the projected ("central scenario") emissions for the Budget 3 period in Table A7 (p212) calculated more optimistically within the possible range than in the preceding budget periods?

The central projection is based on central assumptions of fossil fuel prices, economic and population growth and is estimated in a consistent way for each budget period. Uncertainty ranges around the central projection are then built up from individual components of uncertainty. These include the uncertainty in the assumptions of fundamentals such as energy prices and growth, as well as other uncertainty associated with modelling and policy delivery.

The uncertainty ranges around the central projection increase as the projections look further into the future (207 MtCO2 in budget 1, 249 MtCO2 in Budget 2 and 297 MtCO2 Budget 3). The asymmetry, in the third budget period, in the position of the central projection within the uncertainty range reflects the increasing uncertainty associated with policy delivery, which has a greater effect in the upper bound of the uncertainty as policy under-delivery will result in higher than expected emissions.

5.  According to Table A8 (p212), there is a large expected reduction in emission in the first year of the second budget period (2013). Table A9 (p213) on sales and purchases through EU ETS suggests that the cause is an expected shift from sales of carbon units by UK operators of 16 MtC02e in 2012 to purchases of carbon units by UK operators of 6 MtC02e in 2013. Can you explain why this significant change in the UK's use of EU ETS will occur between 2012 and 2013, and what impact there will be on the achievement of carbon budgets if a smaller than expected shift occurs?

  From 2012 to 2013, there is a change in the EU ETS period from Phase II (2008-12) to Phase III (2013-20). Importantly, there is a move to a more stringent Phase III EU ETS cap in line with UK and EU climate objectives. From 2013, there is a downward linear trajectory for the EU ETS cap of 1.74% per year. This is in contrast to a relatively flat emissions cap across Phase II. This can be seen clearly in the projected contribution to the net UK carbon account from power and heavy industry for 2014-22, in Table A8. However, there is a significant expected reduction in net UK emissions from 248 MtCO2 in 2012 to 224 MtCO2 in 2013. The main reason for this is that the downward linear trajectory for the EU ETS cap of 1.74% per year is taken from a 2010 starting point. So to calculate the 2013 cap level, the 1.74% line is drawn through 2011 and 2012 before actually appearing in the lower emissions figures for 2013. In effect, three years of emission reductions are appearing in 2013, hence the significant step down in that year.

The projected sales or purchase of carbon units by UK operators in the EU ETS is presented in Table A9 (p213). These are calculated as the difference between the projected UK domestic emissions in the traded sector and the UK's share of the EU ETS cap. The change from being a net seller of carbon units in 2012 to a net purchaser is in part a result of the change in the UK's share of the EU ETS cap (as shown in Table A8), and not the cause of the step change in figures in Table A8.

  The projected shift in "traded" share of the carbon budget, effectively the UK's share of the EU ETS cap, is "locked in" under the EU 2020 package. If UK domestic emissions in the traded sector exceed the level of allowances, then UK operators are required to purchase a corresponding number of carbon units to offset this increase. As a result there is no impact on the traded share of the net UK carbon account, and the UK should not under-perform on its traded sector share of the carbon budgets.

DECC RESPONSE TO ADDITIONAL QUESTIONS FROM THE EAC ON CARBON BUDGETS FOLLOWING ED MILIBAND'S EVIDENCE SESSION ON 27 OCTOBER

1.  During the session on 27 October, Members asked a question based on a "2%" cut in emissions on 2008 levels by 2020 for the power and heavy industry sector, reported in the Low Carbon Transition Plan. We now understand from officials that this was a typographical error in some of the print run, which was later corrected to "22%". To ease the confusion, the Committee now wishes to ask: to what extent is a cut of 22% of emissions on 2008 levels by 2020 for the power and heavy industry sector, reported in the Low Carbon Transition Plan, consistent with the Committee on Climate Change's vision for almost complete decarbonisation of power generation by 2030?

  The EU ETS drives a 22% cut in emissions in the power and heavy industry sector. Power generation (ie the major power producers) are within this sector. DECC's most recent emissions projections, which accompanied the Low Carbon Transition Plan, show that carbon emissions from major power producers will decline by 47% on 2007 levels by 2020, given our current policies. To be on course to achieve the required level of decarbonisation in 2030, the CCC have said that emissions from power generation need to decline by 50% on 2008 levels. DECC's projections are therefore reasonably consistent with the decarbonisation trajectory required by the CCC.

The expected emissions reduction is less significant for heavy industry (such as refineries, steel mills or cement plants) because it is likely to decarbonise at a slower pace than the power sector. Options to decarbonise electricity, such as increased renewables, carbon capture and storage and nuclear are not likely to be so readily available for heavy industry by 2020. However, there are policies in place to ensure heavy industry emissions will reduce—including their inclusion in the EU Emissions Trading System, and through the Climate Change Agreements and Climate Change Levy package.

2.  Why does the Low Carbon Transition Plan make reference to 2008 as a base year, rather than other years which are already used in other emissions performance reporting?

It was felt in producing the Low Carbon Transition Plan that it would be useful in some cases to describe emissions reductions against 2008 levels because this gives a clearer indication of the reductions that need to be achieved from current emissions. The legally binding base year for our targets under the Climate Change Act 2008 remains 1900,[9] and the Transition Plan makes this clear when referring specifically to the Act and carbon budgets as, for example, in Chapter 2. In many cases, where it aids understanding, the plan refers to both 2008 and 1990 baselines (see, for example, the first bullet point of the Executive Summary on p4).

3.  You told us that the current carbon price was lower than you would wish. What level of carbon price do the Government consider is needed to drive investment in low-carbon technologies and infrastructure?

The Government do not take the view that any particular price of carbon is the "right" price. Even with the current price of around €14, the EU and the UK can still be expected to deliver the required emission reductions by 2020. This is because the EU Emissions Trading System cap determines the level of emission reductions achieved, and not the carbon price.

However, looking beyond 2020, we will need to meet even more demanding carbon reduction targets. For these, we will need the carbon price to be incentivising greater take-up of low-carbon technologies before 2020. In this context, the current carbon price does appear low. The most effective way of strengthening the carbon price is by limiting the supply of allowances by tightening the cap. The EU ETS cap will be reviewed following an international climate change agreement at Copenhagen.

4.  What assessment have the Government made of the impact of the credit crunch on availability of low-cost long-term financing for low-carbon and renewable generation projects?

  The credit crunch is having an impact. The number of banks in the project finance markets open to energy developers has reduced. The remaining banks have shortened the tenor of debt available to projects and focused more on major core clients rather than independent developers. The cost of debt has increased and deals can take longer to close.

Funding constraints have been a particular problem for smaller and mid-sized, independent renewables developers. In order to mitigate this, the European Investment bank (EIB) and three UK-based banks (RBS, Lloyds and BNP Paribas Fortis) have launched a new lending scheme for small and mid-sized onshore wind farm development. The scheme should improve liquidity in the project finance market. We expect the scheme to facilitate lending of over £1bn over the next couple of years and, based on the experience it draws from this scheme, we hope the EIB will examine the financing of other forms of renewable energy in the future.

5.  DECC officials recently gave a briefing to the Committee on proposals for carbon valuation which would now reflect the costs of mitigating emissions. How will DECC ensure that the new proposals on carbon valuation are applied in policy decision-making across Whitehall?

  All Government Departments must carry out carbon impact assessments for those policy options that will have a significant impact on emissions. This requires analysts to quantify the carbon impacts of their policies, and to value these impacts using the new target consistent carbon values. Alongside the PSA indicator (see below) on the cost-effectiveness of climate change policies, this requirement ensures strong monitoring of the use of the new carbon values, leading to greater enforceability of its use.

Under PSA 27 Indicator 6, Government Departments conducting Impact Assessments are required to report on the proportion of abatement for which the cost falls below the new target consistent carbon price. This is intended to provide an indicator of the cost-effectiveness of emissions reductions policies across Government. This requirement applies to projects that meet a de minimis threshold:

    — for policies with a lifetime of less than 20 years, the carbon impact test is required if the stream of C02e savings exceeds 0.1 MtCO2e average per year.

    — if the policy lifetime is above 20 years, the carbon impact test is required if the stream of C02e savings exceeds 2.0MtCO2e over the lifetime and an average per year of 0.05 MtCO2e.

  Practical guidance on how to apply the new carbon values in policy appraisal was published alongside the revised approach for carbon valuation in UK policy appraisal.[10] We are currently developing more comprehensive guidance on how to value energy usage and greenhouse gases for appraisal and evaluation to supplement current Green Book Guidance. This guidance will explain in more detail how the new carbon values should be used in economic appraisal across Government along with revised guidance on other factors including fossil fuel price assumptions and carbon emissions factors. It will be updated annually.

6.  In the Traded Sector, why is progress against the UK carbon budget judged solely by the allocation of emissions permits within the EU ETS, rather than actual emissions? To what extent would counting actual emissions be more consistent with the UK's annual reporting of greenhouse gas inventories to the UNFCCC?

  The Carbon Accounting Regulations 2009, which set the rules for calculating the net UK carbon account and determining compliance with carbon budgets, were approved by both Houses of Parliament in April 2009, following a public consultation on the proposed accounting system in October 2008. The starting point in the traded sector is actual emissions as reported in the UK greenhouse gas inventory. To take account of trading under the EU Emissions Trading System, a credit is then subtracted (if the UK is a net buyer of carbon units under the ETS), or a debit added (if the UK is a net seller). This has the overall effect of counting the UK's EU ETS allocation against the budget.

This approach—which was agreed by a significant majority of consultation respondents—has been taken because the EU ETS is the primary policy tool for delivering emissions reductions in the traded sector and decarbonising power generation. We believe that it would be misleading to count actual UK emissions against carbon budgets, without taking account of EU ETS trading. Doing so could mean, for example, that we could report reduced emissions in the UK, when these might actually be displaced by increased emissions elsewhere in the EU (or vice versa). Access to offsetting within the EU ETS is strictly limited, and the Low Carbon Transition Plan shows our expectation that the UK will vary over the three budget periods between being a net seller and a net buyer of carbon units from abroad (Chart A3, p211 and 214).

  It is entirely consistent with the UK's annual reporting of greenhouse gas inventories to the UNFCCC, and with the international rules for monitoring progress against Kyoto targets, under which the impact of trading under the EU ETS is taken into account. The annual statements of emissions required by the Climate Change Act—the first of which will be published by 31 March 2010 for the year 2008—must be completely transparent in setting out actual emissions, as well as details of the number and types of credits and debits to the net UK carbon account.

7.  The Committee on Climate Change concludes in its progress report that a mechanism for allowing access to the transmission network for wind power generation should be in place by mid-2010 (page 121). What are the Government doing to ensure that such a mechanism is put in place?

  The Government recognise that improved access for new renewable generation such as wind power is essential in helping to tackle climate change. As the Committee on Climate Change has recognised in their recent report, Ofgem has already taken the decision to have in place an interim access arrangement to ensure that renewable generation is able to gain access to the transmission network even where it is capacity constrained. However, we agree with the Committee's view of the importance of putting in place an enduring regime for grid access by mid-2010. That is why Government are intervening using Energy Act Powers to see the grid access reform process started by industry through to a timely and successful conclusion. We are working to get this in place by June 2010.

8.  In its progress report, the Committee on Climate Change has set out a series of milestones and indicators by which progress in delivering emissions reductions might be monitored. What is the Department's assessment of the utility of these milestones and indicators? Are there areas where other measures might also be needed? Do the Government already collect all the data that would be needed for these milestones and indicators, should they all be adopted?

The Government will respond formally to the CCC's progress report, including the indicators, by 15 January 2010. However, we agree with the need identified by the CCC for a comprehensive framework that will enable future progress on key policies for reducing emissions and underlying drivers to be tracked. Monitoring progress on the basis of historic emissions data alone will not be sufficient due to time lags in receiving data and long project lead times.

The Government are developing a similar indicator-based framework for monitoring progress in reducing greenhouse gas emissions that will complement emissions data and allow us to identify at an early stage where risks to meeting our carbon budgets may lie. The indicators for monitoring progress in different sectors will form part of the Carbon Reduction Delivery Plans all Government Departments are to publish in spring 2009, in which they will set out how they aim to meet their shares of the carbon budgets.

  We support the pragmatic and flexible approach that the CCC makes clear it will take when assessing progress against its indicators. It is important to preserve flexibility about where emissions reductions are delivered to meet the carbon budgets if we are to ensure that they are met in the most cost-effective way.

9.  What is being done to ensure that individual decisions taken by the Infrastructure Planning Commission are, when taken together, compatible, with the carbon budgets (for example, that gas-fired power stations meeting NPS guidance individually might lock the UK into high emissions if many such power stations were approved)? What is being done to ensure that National Policy Statements reflect emissions reductions targets following Copenhagen?

  The Government policies that underlie energy National Policy Statements have been set in accordance with the carbon budgets and targets in the Climate Change Act. The UK Low Carbon Transition Plan describes the contribution to be made by policies in different sectors of the economy, including the power sector, to meeting the first three carbon budgets. The draft NPSs, published on 9 November, set out how the IPC should apply these policies in planning decisions and are therefore fully compatible with the Transition Plan and with carbon budgets. Given this, the IPC will not be required to assess individual applications against the carbon budgets. The draft NPSs instead set out very clearly the terms on which new carbon-emitting energy infrastructure can be approved by the IPC in accordance with the relevant Government policies.

The carbon budgets are legally binding and it is the responsibility of Government to meet them, drawing on the advice of the Committee on Climate Change. Government have committed to tightening the carbon budgets following a satisfactory global deal at Copenhagen. If, after doing this, policies are changed or new policies introduced to ensure that the new budgets can be met, consideration will be given as to whether energy NPSs should be amended to reflect the new policy environment.
