What is a just transition?

The principle that moving away from fossil fuels should not impose the costs on the workers and communities that depend on them — and that a transition perceived as unfair will be resisted, whatever its environmental merits.

Where the idea originated. From the trade union movement, initially in response to environmental regulation affecting industrial employment. The core argument is that environmental policy and workers' interests need not be opposed, but only if the transition is deliberately managed.

The problem it addresses. Fossil fuel employment is geographically concentrated — coalfields, oil and gas regions, refining and heavy industry towns. Closure does not distribute its effects across a national economy; it lands on specific places where the industry is frequently the largest employer, supports a supply chain, and funds the local tax base.

The jobs are also frequently well paid, unionised and skilled, while replacement employment is commonly lower paid and less secure — so "there will be green jobs" is not an adequate answer if the jobs are in different places, at lower wages, with different skills.

What the historical record shows. The UK coalfield closures of the 1980s are the reference case: communities that lost their industry experienced elevated unemployment, ill health, and economic decline persisting for decades. Research on former coalfields has documented outcomes still visible in the present — which is the evidence that abrupt transition without provision does lasting damage.

What a just transition involves in practice:

Anticipating closure rather than reacting to it, with timescales long enough to act.

Retraining with genuine pathways, not generic schemes, and recognition that skills transfer imperfectly.

Locating replacement industry in affected regions, which requires deliberate policy since it will not happen by default.

Income support and early retirement provision for older workers unlikely to retrain.

Involving workers and communities in planning, rather than consulting after decisions.

Investment in the place, not only in individuals.

Why it is politically central. Climate policy that visibly imposes costs on identifiable communities generates durable opposition, and several prominent political backlashes have taken this form.

It now appears in international agreements and in national climate legislation.
