The process leading to a net zero carbon economy by mid-century will have massive effects on jobs, labour relations and income distribution. The idea of just transition – that achieving the ambitious objectives to bring climate change under control will only be possible if the transition to a net-zero carbon economy is balanced and just – has evolved in the last four decades from a union initiative to a complex policy framework adopted by international organizations, and also referred to in the COP21 Paris Agreement (UNFCCC, 2015). Building on literature analysis, this article deconstructs the concept of ‘just transition’ by discussing its various interpretations and dimensions and highlighting the role of trade unions in applying it. Based on sectoral case studies, concrete examples from two key sectors of the European economy – energy and automobile – are given, where massive employment transitions are under way and social dialogue plays a key role. Conclusions about the changing role of trade unions and the importance of co-operative industrial relations are drawn.

The global pandemic has taught us that we can focus the attention of the healthcare system on a clear intention when there is a looming threat. Climate action is required from multiple stakeholders particularly private sector suppliers in order to achieve the net-zero carbon emission by 2050 goal established by the Canadian government. Also building climate resilience among healthcare institutions and their supply chains is urgently needed, as they are already affected by a changing climate. By adopting a circular economy framework, the industry can move away from the current damaging take, make waste economic model and adopt a more sustainable model characterized by designing out waste and pollution, keeping products and materials in use, and regenerating natural systems. Health leaders can adopt sharing platforms, product as a service, reduce single use products, encourage extended producer responsibility, and value-based procurement in order to further these aims.

Many nations have committed to midcentury net zero carbon emissions targets in line with the 2015 Paris Agreement. These require systemic transition in how people live and do business in different local areas and regions within nations. Indeed, in recognition of the climate challenge, many regional and city authorities have set their own net zero targets. What is missing is a grounded principles framework to support what will inevitably be a range of broader public policy actions, which must in turn consider pathways that are not only technically, but economically, socially and politically feasible. Here, we attempt to stimulate discussion on this issue. We do so by making an initial proposition around a set of generic questions that should challenge any decarbonisation action, using the example of carbon capture and storage to illustrate the importance and complexity of ensuring feasibility of actions in a political economy arena. We argue that this gives rise to five fundamental ‘Net Zero Principles’ around understanding of who really pays and gains, identifying pathways that deliver growing and equitable prosperity, some of which can deliver near-term economic returns, while avoiding outcomes that simply involve ‘off-shoring’ of emissions, jobs and gross domestic product.

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.

Whole-building model optimizations have been performed for a single-detached house in 5 locations with varying climates, electricity emissions factors, and energy costs. The multi-objective optimizations determine the life-cycle cost vs. operational greenhouse gas emissions Pareto front to discover the 30-year life-cycle least-cost building design heated 1) with natural gas, and 2) electrically using a) central air-source heat pump, b) ductless mini-split heat pump c)ground-source heat pump, and d) electric baseboard, accounting for both initial and operational energy-related costs. A net-zero carbon design with grid-tied photovoltaics is also optimized. Results indicate that heating system type influences the optimal enclosure design, and that neither building total energy use, nor space heating demand correspond to GHG emissions across heating system types. In each location, at least one type of all-electric design has a lower life-cycle cost than the optimized gas-heated model, and such designs can mitigate the majority of operational GHG emissions from new housing in locations with a low carbon intensity electricity supply.

Climate change embeds inequities and risks reinforcing these in policies for climate change remediation. In particular, with policies designed to achieve “net zero” carbon dioxide, offsets may be considered inequitable if seen to avoid or delay gross emission reductions; offsets to emissions through technologically mature methods of carbon dioxide removals (CDR) require natural resources at scales threatening food security; knowledge of the potential of immature CDR is largely a global north monopoly; and CDR in particular environments is ill-understood and its implications for development unexamined. The use of CDR to contribute to robust progress toward Paris climate goals requires global agreement on simultaneously reducing emissions and enhancing removals, equity in burden sharing, and an interdisciplinary effort led by individual jurisdictions and focused on the co-development of technologies and governance to create CDR portfolios matched to local needs.
