Emissions for Birmingham 2010 by end use and fuel.

(in ktC02)

Commercial: 2364

Domestic buildings: 2134

Transport: 1460

Total 2010 : 5969ktC02

In 1990 emissions were 6312 ktCO2 and 5578 in 2010 (a 12% reduction).

Estimates to 2026 are:

So we reduce by 2641 ktCO2 over 26 years from 2005 to 2026 or 1906 ktCO2 over 16 years from 2010 to 2026.

fv = pv(1+i)^n

i = (6313-3672)/6313

= 0.4183

Back calculation:

3672((1+0.0213)26) = 6351.690121829307 (cf. 6313).

The national Carbon Plan outlines an emissions trajectory that will reduce emissions by 50% by 2027. The biggest reductions will take place in the power sector, but alongside this significant deployments of renewable heat and energyefficiency measures are required in the next 20 years. And in transport, an ambitious uptake of low carbon vehicles is needed.

Birmingham’s current emissions target, 60% by 2026, exceeds the trajectory set out in the (national ed.) Carbon Plan. However, early progress on building stock energy efficiency and low carbon heating and transport will put the city on the right pathway to achieve its ambition, and subsequent longer-term emissions reductions.

Figure 2 shows the effect of reductions in emissions from decarbonisation of the national grid and technological change.

an emissions reduction in the region of 40% reductions could be plausible as a result of UK-wide energy system changes between 1990 and 2026.

The chart claims that 3627 is 42% less than 5578 (1 say 34.9767%). This implies that the city needs to save 18% of emissions on top of the national effort. I say 26% is needed.

To get to 60% reduction by 2026:

Emissions from large industrial facilities and from other fuels have not been included and consequently some variance with Birmingham’s actual emissions can be expected.

The only real data for Birmingham’s emissions were collected between 2005 and 2010.

Better check:

(6313-5578)100/6313 = 11.6426%.

Heavy industry is ignored.
