Sustainability Reporting

Section 5: Carbon Management

Click anywhere to move to the next slide


Carbon management plans

Carbon Management Plans

  • Why are they required?

  • How is waste incorporated?

  • What is changing when including waste?

Carbon management in context

Carbon Management in context

  • Key step to meet the Duties under the Climate Change (Scotland) Act

  • Almost all Scottish Public Bodies have a Carbon Management Plan (around 150 in total)

  • Key components of a Carbon Management Plan:

    • Carbon baseline

    • Carbon reduction target

    • Project plan to meet target

    • Governance and reporting

Waste within carbon management plans

Waste within Carbon Management Plans

  • As a minimum, the Carbon Management Plan includes internal waste; Councils include MSW

  • Included in:

    • Carbon baseline

    • Carbon reduction target

    • Project plan to meet target

Click anywhere to move to the next slide


Assessing the baseline 1

Assessing the baseline (1)

  • Estimate of tonnes

  • If (1) own waste:

    • Based on waste survey

    • Estimate from volume of bins and uplift frequency

  • If (2) entire MSW collection:

    • From reports to SEPA

      (2) Is much more accurate than (1)

Assessing the baseline 2

Assessing the baseline (2)

(1) From own premises and processes

Typically 1%-6% of total baseline

or

(2) For Councils from entire MSW collection

Typically 30%-35% of total baseline

Assessing the baseline 3

Assessing the baseline (3)

  • Carbon Trust emissions factor:

    • 447 kgCO2e/tonne

  • Not a fixed factor (unlike for gas, oil, etc.)

  • Based on aggregation of different aspects:

    • Waste composition into landfill

    • Landfill capacity

    • Electricity generation rates from landfill

    • Fugitive emissions from landfill

Assessing the baseline 4

Assessing the baseline (4)

  • Each aspect has changed:

    • Composition of waste sent to landfill (increased recycling)

    • Improved landfill site management (lower fugitive emissions)

    • Increased levels of electricity generation (from landfill gas, encouraged by incentives)

    • Zero Waste Plan (waste segregation, landfill bans on biodegradable material)

Click anywhere to move to the next slide


Assessing the baseline 5

Assessing the baseline (5)

  • So 447 kgCO2e/tonne no longer a representative emissions factor for waste

  • Ideally move to using the Carbon Metric, but this has complications (as outlined earlier)

  • However, updated values for use in Carbon Management Plans are now being developed

Assessing the baseline 6

Assessing the baseline (6)

Options include:

  • Scottish Mixed Household Waste to Landfill (HH)

    = 322 kgCO2e/tonne

  • Scottish Mixed Commercial & Industrial Waste to Landfill (C&I)

    = 299 kgCO2e/tonne

Click anywhere to move to the next slide


Assessing the baseline 7

Assessing the baseline (7)

Should Public Sector organisations adopt the Commercial & Industrial or the Household factors for Carbon Management Plan reporting?

Click anywhere to move to the next slide


Assessing the baseline 8

Assessing the baseline (8)

HH waste to landfill

= 322 kgCO2e/tonne

C&I waste to landfill

= 299 kgCO2e/tonne

Two significant differences:

  • Plastic

  • Paper & Cardboard

Click anywhere to move to the next slide


Baseline example 1

Baseline Example (1)

  • Council includes MSW in the baseline

  • Revised to use HH factor

  • Waste emissions = -28%

  • Total emissions = -9%

Click anywhere to move to the next slide


Baseline example 2

Baseline Example (2)

  • College includes own waste in the baseline

  • Revised to use C&I factor

  • Waste emissions = -33%

  • Total emissions = -2%

Click anywhere to move to the next slide


Implications

Implications

  • Will need careful explanation to internal and external stakeholders

  • Resist the temptation to claim a 9% reduction!

  • Need to reassess target and projects at the same time

  • Zero Waste Scotland plan guidance on this topic

Revising the target

Revising the target

  • Target must be on the same calculation basis as the baseline

  • Typically, targets set top-down:

    e.g. 20% reduction by 2015

  • So resetting the baseline has a simple ‘knock-on’ impact

Revising the project details

Revising the project details

  • May be same basis as baseline and target

  • But large investment projects should use the full Carbon Metric, as recommended in the Zero Waste Plan

  • Will need to convert to the same approach as the baseline and target

  • Potential for confusion at this stage?

In summary

In Summary …

  • Reviewed the policy context

  • Introduced the principles behind the Carbon Metric

  • Provided examples of the Carbon Metric in use

  • Introduced a new way to include waste within Carbon Management Plans
