Part 3 - Net Scottish Emissions Account ( NSEA) for 2014

Requirements of the Act

Section 34 of the Act requires that the report:

  • state the amount of the net Scottish emissions account for the target year (subsection (3)(a)).
  • state the proportion of the reduction in the net Scottish emissions account which is accounted for by reductions in net Scottish emissions (subsection (3)(b)).
  • state the total amount of carbon units:
    • that have been credited to or debited from the net Scottish emissions account for the target year (subsection (3)(c)(i));
    • that have been purchased in the target year (subsection (3)(c)(ii));
    • that have been held and not surrendered in the target year (subsection (3)(c)(iii)).
  • give details of the number and type of those carbon units (subsection (3)(d)).
  • for each year in the period 2011-2050:
    • state the amount of the NSEA for each preceding target year (subsection (5)(a));
    • state the cumulative amount of the net Scottish emissions account for the target year and all preceding target years (subsection (5)(b)).

Amount of the Net Scottish Emissions Account for 2014

Achievement of Scotland's greenhouse gas emissions targets is measured against the level of the net Scottish emissions account ( NSEA). The NSEA is defined in the Act as the aggregate amount of "net Scottish emissions" of greenhouse gases, reduced / increased by the amount of carbon units credited to / debited from it in accordance with the Carbon Accounting Scheme Regulations made under the Act.

Table 4 provides the amount of the net Scottish emissions account in 2014, including the total amount of carbon units that have been credited to or debited from the NSEA as the result of the operation of the EU ETS in Scotland.

Based on the NSEA, Scotland's emissions fell by 12.5 per cent in 2014 on the previous year. The longer term trend to date shows a reduction of 45.8 per cent from the 1990/1995 baseline period. This means that the level of Scotland's statutory 2020 target to reduce emissions by 42 per cent from baseline levels has been exceeded, six years early .

Proportion of the reduction in the net Scottish emissions account which is accounted for by reductions in net Scottish emissions

Section 8 of the Act places a duty on the Scottish Ministers to ensure that reductions in net Scottish emissions of greenhouse gases account for at least 80 per cent of the reduction in the net Scottish emissions account in any target year - the "domestic effort target". In effect, this ensures that the majority of the action to meet emission reduction targets is taken domestically, rather than by offsetting domestic emissions through the purchase of international credits.

There are two mechanisms by which carbon units can be credited to / debited from the NSEA.

i As the result of the operation of the EU Emissions Trading System ( EU ETS) in Scotland. The details of this mechanism are set out in the Annex to this report.

ii. Ministers may credit to the NSEA any international carbon units purchased by them, thereby offsetting domestic emissions. The Climate Change (Limit on Carbon Units) (Scotland) Order 2011 sets limits for the period 2013-2017 which allows Ministers the option to purchase (credit) up to 203,600 carbon units in 2014 in addition to credits or debits to the Scottish account through the operation of the EU ETS.

For the specific purpose of ascertaining whether the domestic effort target has been met, the Act stipulates that the use of carbon units through the operation of the EU ETS is treated as though it is a reduction in "net Scottish emissions".

For the purposes of the domestic effort target in 2013 and 2014, the net Scottish emissions and net Scottish emissions account are the same. This is because no units were credited to the NSEA in either of the years as a result of the purchase of international carbon units. This means that the reduction in net Scottish emissions of greenhouse gases account for 100 per cent of the reduction in the net Scottish emissions account in the 2014 target year (see Table 5).

The fixed annual targets for 2010-2027 were set on the basis of the 1990-2008 inventory, which was the latest inventory available at the time. This estimated baseline emissions to have been 70.201 MtCO 2e and the 2020 target was set at 40.717 MtCO 2e, which equated to a 42 per cent reduction in line with the level of the 2020 interim target set by the Act. Successive revisions means that the reductions required to meet each of the fixed annual targets is now significantly greater than was envisaged when the targets were set. So, for example, to reach the 2020 annual target now equates to a 47.3 per cent reduction in emissions (Table 11).
