<p>Greenhouse gas emissions from damaged peatlands in the UK contribute around 5% to the annual national UK emissions. This has prompted a large national effort to restore these ecosystems as part of the package of action that aims to deliver net zero by 2050 in the UK and 2045 in Scotland. Eroded peatlands cover an estimated 275kha in Scotland, yet continuous monitoring data on the carbon losses from such sites are very sparse, in part due to the challenge in instrumenting such remote and complex terrain with eddy covariance equipment. We present a full, pre-restoration, 18-month data series of carbon dioxide and energy budget from a typical Scottish eroded peatland and show initial data that suggests sensitivity of the sign of the net annual CO2 budget to interannual climate variability.</p>

<p>In May 2019, a major wildfire event affected >60 km2 within the 4000 km2 Flow Country in Northern Scotland, UK, a flagship blanket bog peatland that is being considered for UNESCO World Heritage Status. While the fire itself created significant damage, it also led to an extraordinary and unique opportunity to compare burned and unburned landscape scale greenhouse gas flux and surface energy dynamics using sites that, crucially, have otherwise identical biophysical characteristics (slope, aspect, peat depth) and land management histories. Since September 2019, carbon dioxide and methane flux data have been collected alongside other micrometeorological variables. Due to the COVID-19 lockdown in the UK, the team had severe difficulties in maintaining the equipment and hence, only partial and preliminary data will be reported here to showcase the findings from this project to date. The data obtained so far suggest a post-fire reduction in net CO2 emissions for a period of one year since the beginning of our monitoring campaign.</p>

This Policy Brief reviews the experience of the UK in developing principles for the governance of carbon dioxide removal (CDR) at scale. Early discussions on CDR governance took place in two separate and somewhat disjointed policy domains: forestry, on the one hand, and R&D support for novel “geoengineering” technologies, on the other. The adoption by the UK government of a 2050 “net zero” target is forcing an integration of these disparate perspectives, and should lead to a more explicit articulation of the role CDR is expected to play in UK climate strategy. This need for clarification is revealing some of underlying tensions and divisions in public views on CDR, particularly when it comes to forms of capture and sequestration deemed to be “non-natural.” We propose some principles to ensure that the development and deployment of carbon dioxide removal at scale strengthens a commitment to ambitious climate change mitigation and can thus enjoy broad public support.

The UKGBC Net Zero Carbon Buildings Framework was published in April 2019 following an industry task group and extensive consultation process. The framework acts as guidance for achieving net zero carbon for operational energy and construction emissions, with a whole life carbon approach to be developed in the future. In consultation with industry, further detail and stricter requirements are being developed over time. In October 2019, proposals were set out for industry consultation on minimum energy efficiency targets for new and existing commercial office buildings seeking to achieve net zero carbon status for operational energy today, based on the performance levels that all buildings will be required to achieve by 2050. This was complemented by modelling work undertaken by the LETI network looking into net zero carbon requirements for new buildings. In January 2020 UKGBC published its guidance on the levels of energy performance that offices should target to achieve net zero and a trajectory for getting there by 2035. This paper describes the methodology behind and industry perspectives on UKGBC’s proposals which aim to predict the reduction in building energy intensity required if the UK’s economy is to be fully-powered by zero carbon energy in 2050. Practical application: Many developers and investors seeking to procure new commercial offices or undertake major refurbishments of existing offices are engaging with the ‘net zero carbon’ agenda, now intrinsic to the legislative framework for economic activity in the UK. A UKGBC initiative effectively filled a vacuum by defining a set of requirements including energy efficiency thresholds for commercial offices in the UK to be considered ‘net zero carbon’. This paper provides all stakeholders with a detailed justification for the level of these thresholds and what might be done to achieve them. A worked example details one possible solution for a new office.

AbstractThe UK Plan for a Green Industrial Revolution aims to ban petrol and diesel cars by 2030 and transition to electric vehicles (EVs). Current business models for EV ownership and the transition to net-net zero emissions are not working for households in the lowest income brackets. However, low-income communities bear the brunt of environmental and health illnesses from transport air pollution caused by those living in relatively more affluent areas. Importantly, achieving equitable EV ownership amongst low-and middle-income households and driving policy goals towards environmental injustice of air pollution and net-zero emissions would require responsible and circular business models. Such consumer-focused business models address an EV subscription via low-income household tax rebates, an EV battery value-chain circularity, locally-driven new battery technological development, including EV manufacturing tax rebates and socially innovative mechanisms. This brief communication emphasises that consumer-led business models following net-zero emission vehicles shift and decisions must ensure positive-sum outcomes. And must focus not only on profits and competitiveness but also on people, planet, prosperity and partnership co-benefits.
