Committee on Climate Change – recommendations to government – lots on aviation carbon policies needed

The Committee on Climate Change has published its guidance for the UK government on its Sixth Carbon Budget, for the period 2033 – 37, and how to reach net-zero by 2050.  There is a great deal of detail, many documents, many recommendations – with plenty on aviation. The intention is for UK aviation to be net-zero by 2050, though the CCC note there are not yet proper aviation policies by the UK government to achieve this. International aviation must be included in the Sixth Carbon budget. If the overall aviation CO2 emissions can be reduced enough, it might be possible to have 25% more air passengers in 2050 than in 2018. The amount of low-carbon fuels has been increased from the CCC’s earlier maximum realistic estimates of 5-10%, up to perhaps 25% by 2050, with “just over two-thirds of this coming from biofuels and the remainder from carbon-neutral synthetic jet fuel …” Residual CO2 emissions will need to be removed from the air, and international carbon offsets are not permitted. There is an assumption of 1.4% efficiency improvement per year, or at the most 2.1%. There “should be no net expansion of UK airport capacity unless the sector is on track to sufficiently outperform its net emissions trajectory.”  The role of non-CO2 is recognised, but not included in carbon budgets; its heating effect must not increase after 2050.  And lots more … .Tweet     The main full report The Sixth Carbon Budget – the road to UK’s Net Zero , The Sixth Carbon Budget – Methodology reporting . Policies for the Sixth Carbon Budget and Net Zero . There are many sector summaries;  The Aviation sector summary is The Sixth Carbon Budget Aviation The CCC’s Key Recommendations Our recommended pathway requires a 78% reduction in UK territorial emissions between 1990 and 2035. In effect, bringing forward the UK’s previous 80% target by nearly 15 years. The Sixth Carbon Budget can be met through four key steps: 1. Take up of low-carbon solutions. People and businesses will choose to adopt low-carbon solutions, as high carbon options are progressively phased out. By the early 2030s all new cars and vans and all boiler replacements in homes and other buildings are low-carbon – largely electric. By 2040 all new trucks are low-carbon. UK industry shifts to using renewable electricity or hydrogen instead of fossil fuels, or captures its carbon emissions, storing them safely under the sea. 2. Expansion of low-carbon energy supplies. UK electricity production is zero carbon by 2035. Offshore wind becomes the backbone of the whole UK energy system, growing from the Prime Minister’s promised 40GW in 2030 to 100GW or more by 2050. New uses for this clean electricity are found in transport, heating and industry, pushing up electricity demand by a half over the next 15 years, and doubling or even trebling demand by 2050. Low-carbon hydrogen scales-up to be almost as large, in 2050, as electricity production is today. Hydrogen is used as a shipping and transport fuel and in industry, and potentially in some buildings, as a replacement for natural gas for heating. 3. Reducing demand for carbon-intensive activities. The UK wastes fewer resources and reduces its reliance on high-carbon goods. Buildings lose less energy through a national programme to improve insulation across the UK. Diets change, reducing our consumption of high-carbon meat and dairy products by 20% by 2030, with further reductions in later years. There are fewer car miles travelled and demand for flights grows more slowly. These changes bring striking positive benefits for health and well-being. 4. Land and greenhouse gas removals. There is a transformation in agriculture and the use of farmland while maintaining the same levels of food per head produced today. By 2035, 460,000 hectares of new mixed woodland are planted to remove CO2 and deliver wider environmental benefits. 260,000 hectares of farmland shifts to producing energy crops. Woodland rises from 13% of UK land today to 15% by 2035 and 18% by 2050. Peatlands are widely restored and managed sustainably. . The CCC has 4 alternative pathways for the future. These are: Balanced New Zero Pathway  – their main one also (depending on more or less innovation, and

Keeping ahead of COVID-19

This rapidly evolving corona virus (COVID-19) has imposed an unsettling situation upon our community and its businesses. While we are maintaining to operate a "business as usual" approach, we are taking a number of changes to help protect both you as customers and us as drivers during these difficult times.

All of our vehicles are sanitised before and after each journey / dividing screens fitted to separate the rear of the vehicle.

We also offer delivery services for local businesses to help get essential items to local customers as well as across the UK.
