The climate and environment platform rests on three principles that distinguish Common from every other UK political party:
Principle one: Environmental policy is industrial policy. Every wind turbine we need is a wind turbine British factories could be building. Every solar farm component, every battery, every heat pump, every grid-scale storage unit represents either imported manufacturing deficit or domestic industrial opportunity. Net zero delivered through Chinese imports is fiscal expenditure. Net zero delivered through British manufacturing is fiscal investment. We choose the second.
Principle two: Fiscal discipline on net zero, not ideological commitment. Where transition measures deliver obvious benefits (energy security, industrial employment, export opportunity, air quality), proceed with confidence. Where measures deliver marginal climate benefit at disproportionate cost (small-scale retrofit subsidies, electric vehicle mandate on schedules that outpace supply chains, heat pump installation targets divorced from housing stock realities), reform or defer. This is not climate scepticism; it is climate seriousness.
Principle three: Environmental stewardship is a conservative value, properly understood. Clean rivers, functional ecosystems, sustainable fisheries, productive farmland, resilient coastlines: these are the inheritance we receive and the inheritance we owe to those who come after. The destruction of British rivers by privatised water companies is a moral failure as much as an environmental one. Restoration is not radical politics; it is common decency applied to the physical country.
The UK's statutory net zero by 2050 target is retained. The pathway is reformulated around industrial opportunity.
Fundamental reframe: net zero is not a cost we pay. It is a transition we manage, and the question is whether we manage it such that British industry benefits or such that Chinese industry benefits. Every pound we spend on imported renewable energy equipment is a pound we have not spent building British manufacturing capacity. Net zero delivered through industrial policy is cheaper than net zero delivered through imports, and generates lasting national wealth.
Wind turbines: Airbus Broughton (Wales) converted to wind turbine manufacturing at industrial scale, as flagged in Productive Britain. Offshore wind manufacturing cluster expanded across the East Coast (Humber, Teesside, Tyne) with specific industrial policy anchor. Onshore component manufacturing capability developed. Export market targeted: UK becomes a wind turbine exporter, not importer.
Solar: UK solar PV manufacturing capability developed from current near-zero base. Partnership model with existing European manufacturers (Meyer Burger, etc.) accelerates timeline. Modest scale initially (2-3 GW/year capacity by Y10) but strategic sovereignty and regional employment.
Batteries: Britishvolt failure not repeated. Strategic backing for Nissan Sunderland battery facility, Jaguar Somerset facility, new facilities as commercial interest emerges. UK battery manufacturing capacity target: 100 GWh/year by Y10. Sufficient for UK automotive transition and grid storage needs.
Heat pumps: UK heat pump manufacturing developed from current imports-dominated position. Particularly important given housing stock retrofit implications: scale requires domestic manufacturing.
Grid infrastructure: cable manufacturing (already strong: Prysmian, Nexans), substation equipment, transformer capability. Nationalised National Grid uses UK-sourced equipment as procurement preference.
EV components: motor manufacturing, power electronics, battery management systems. Existing automotive supply chain redirects to EV components.
Industrial policy linkage: all of the above are subsumed within the broader Productive Britain industrial programme. The defence-anchored derisking narrative applies here too: state demand for renewable energy equipment stabilises private investment in manufacturing capability.
Commitment: UK Carbon Border Adjustment Mechanism (CBAM) introduced, aligned with EU CBAM under ESEP framework.
Purpose: level playing field for UK carbon-intensive industries against imports from jurisdictions with weaker climate policies. Without CBAM, domestic climate policy simply offshores emissions to China, India, Russia: no global benefit, substantial UK deindustrialisation.
Scope: steel, cement, aluminium, fertiliser, hydrogen initially. Expansion to chemicals, basic materials, and eventually finished goods over 10 years.
Revenue: approximately £2-3bn/year by Y10, hypothecated to industrial decarbonisation support.
Strategic benefit: enables UK to maintain competitive domestic production in carbon-intensive sectors during transition. Steel manufacturing at Port Talbot, Scunthorpe, Teesside all benefit directly.
Fossil fuel licensing: managed decline, no new fields (as committed in energy briefing). But existing production and infrastructure retained for duration of their economic lives. North Sea production declining naturally; accelerated shutdown would be fiscally wasteful and industrially damaging.
Petrol and diesel vehicle ban: Y10 (2036) target retained but flexibility on implementation. Plug-in hybrids recognised as transition technology beyond pure BEV mandate where supply chain is not ready. UK auto industry not sacrificed to arbitrary timelines.
Gas heating transition: heat pump rollout accelerated but not mandated on unrealistic timelines. New build standards prioritised (easier, cheaper). Retrofit support targeted rather than universal. Hydrogen for heating remains flagged as unproven and not subsidised beyond industrial applications.
Aviation decarbonisation: sustainable aviation fuel industry developed (as flagged in transport briefing) as industrial opportunity. No punitive aviation taxes beyond existing APD. Direct passenger rail alternatives (ESEP sleeper network, Manchester-Paris direct) reduce demand naturally.
Agriculture emissions: reduction pursued through productivity improvement, not herd culling. Livestock farming remains economically viable under reformed ELM. Soil carbon sequestration incentivised. Methane reduction via feed additive deployment (already technologically viable).
Urban air quality is treated as a public health priority distinct from carbon:
This matters because air pollution kills ~30,000 UK people per year. Addressing it is a first-order policy priority regardless of climate considerations.
UK water privatisation (1989) is one of the most catastrophic policy failures of the last forty years. The numbers are extraordinary:
This is not a failure of regulation. It is a failure of the ownership model. Privatised monopolies extracting dividends from essential infrastructure cannot deliver adequate stewardship. The experiment has run for 35 years and has failed definitively.
Water industry renationalisation: structured, staged, and strict on pollution.
Cost: depends on valuation approach. Realistic range £20-40bn over 5 years, financed via dedicated water infrastructure gilts. Against this sits the asset base, eliminated dividend outflow, and elimination of debt servicing costs that currently consume 40%+ of water company revenue.
Absolute commitment: strictly no pollution standards for nationalised water industry.
Agricultural pollution addressed in parallel:
Beyond pollution, the water system faces supply challenges:
Cost: £10bn capital over 10 years, within nationalised water company investment programme.
North Sea and UK fisheries have been mismanaged for decades. Brexit created an opportunity that has been squandered:
Brexit handed the UK theoretical control of its Exclusive Economic Zone but the UK has not been capable of exercising that control effectively. Common's position recognises this failure and addresses it through genuine fishing sector renewal combined with sustainable stewardship.
Under ESEP (covered in the Nuclear Umbrella and ESEP briefing), UK-EU fisheries relationship is reformulated around shared North Sea stewardship rather than annual quota battles.
Commitment: Marine Protected Area network strengthened and genuinely enforced.
Coastal communities have been among the most economically damaged by the decline of fishing and other marine industries. Specific interventions:
The UK is one of the most nature-depleted countries in the world:
Nature recovery as a national priority alongside climate:
Agricultural nature stewardship:
The UK has extraordinarily concentrated land ownership: approximately 1% of the population owns 50% of England. This is a genuine structural issue with environmental, economic, and social consequences.
Measured intervention:
This is a moderate position. The large-landowner political community is influential and attacking them directly would be strategic error. But transparency, access, and stewardship requirements are defensible on their own merits and chip away at the structural problem without frontal political confrontation.

Capital: substantial but against productive asset base (water infrastructure, reservoirs, renewable manufacturing capacity)
Fiscal integration: absorbs within existing platform envelope. Water nationalisation is the largest single element and is financed via dedicated water infrastructure gilts. The asset creation is substantial and matches the borrowing.
To climate-concerned voters: "We will deliver net zero. We will restore British rivers. We will rebuild British nature. But we will do these things through British industry, British ownership, British stewardship — not through Chinese imports and privatised extraction. This is serious climate policy, not gesture politics."
To climate-sceptical voters: "Climate policy that pays for itself. Factories making windmills. British manufacturing recovery. Clean rivers because we own the water companies. Energy security through domestic production. Net zero where it makes fiscal sense, reformed where it doesn't. This is not ideology. This is competence."
To water bill payers: "The people who took £78 billion in dividends from your water bills while dumping sewage in your rivers will not be thanked. They will be replaced. Water nationalised. Pollution eliminated. Bills stabilised. Investment in the infrastructure that should have been funded decades ago."
To farmers: "Environmental Land Management properly funded at £3 billion per year. Stewardship payments for what you actually deliver. Not destruction of farming for climate policy. Real partnership between productive farming and environmental restoration."
To fishermen: "Genuine control of British waters through strengthened enforcement. Predictable multi-year quotas enabling investment. Fleet modernisation support. Port infrastructure investment. Processing industry development. British fish for British tables. All of this enabled by ESEP partnership that makes shared stewardship actually work."
To manufacturers: "Carbon Border Adjustment Mechanism ensuring British steel, cement, chemicals can compete against imports from jurisdictions with weaker climate policy. Subsidised decarbonisation where genuinely needed. Industrial strategy for the transition. You will not be sacrificed."
To coastal communities: "Coastal infrastructure renewed. Marine industrial cluster development. Housing commitment including coastal regeneration. Levelling up investment prioritised. The communities that the sea made will not be abandoned."
