Delaware House Passes HB 402 To Extend Title V Operating Permit Fees Through 2029

Delaware's House has passed HB 402, a bill that would extend Clean Air Act Title V operating permit fees through 2029 and update the base, user, and programme fee structure for Title V sources from 2027 onward. If the bill is enacted, Title V facilities in Delaware will face continued fee obligations under an adjusted fee schedule and should factor the extended 2027–2029 horizon into budget, permitting, and compliance planning.

Environment Agency Confirms CPI-Linked Increases to Waste (Miscellaneous) Charging Scheme From April 2027

The Environment Agency has updated its Waste (miscellaneous) charging scheme to state that all listed charges will rise on 1 April 2027 and then increase automatically each 1 April in line with the Consumer Prices Index. This locks in predictable but ongoing fee escalations for waste, WEEE, batteries and related activities in England, so operators should factor higher regulatory charges into long-term budgets and commercial planning.

Iowa Legislature Enrols SF2490 Oil And Gas Severance Tax And Pre-emption Bill

In May 2026 the Iowa Legislature enrolled SF2490, a comprehensive oil and gas production bill that creates a 6% severance tax, expands state control over spacing and pooling, strengthens landowner consent and confidentiality, and is scheduled to take effect on 1 July 2026 if signed by the Governor. For operators and investors in Iowa’s oil, gas and emerging natural hydrogen sector, this will materially change project economics and surface-access negotiations, concentrate regulatory authority at state level, and channel extraction revenues into water-quality initiatives and taxpayer relief.

US IRS Announces Hearing on Superfund Taxable Substance Petition for Methyl Methacrylate-Ethyl Methacrylate-Methacrylic Acid Copolymer in a Styrene Solution

The US Internal Revenue Service has scheduled a June 2026 telephonic hearing on a petition to add methyl methacrylate-ethyl methacrylate-methacrylic acid copolymer in a styrene solution to the Superfund taxable substances list. While the list is unchanged for now, chemical manufacturers and importers using this copolymer should track the process and plan for potential future excise-tax exposure and pricing or supply-chain impacts.

England: Environment Agency Implements New Waste Crime Charges and Hourly Rates

The Environment Agency has finalised its consultation on charges for waste crime and regulatory hourly-rate work in England, confirming new waste exemption fees, higher hourly rates for high-risk activities, and fixed charges for medium combustion plants from July 2025 with a new fee for intervention in 2026. These changes substantially increase cost recovery for complex and enforcement-driven work, shifting more cost burden onto poor performers and requiring waste, COMAH and nuclear operators to reassess compliance budgets and pricing for Environment Agency-regulated activities.

Cantabria Law 5/2026 Updates Waste Tariffs and Industrial Safety Fees

Cantabria has adopted Law 5/2026, effective 1 May 2026, increasing municipal waste-treatment tariffs and introducing new fixed fees for industrial registrations and Seveso safety documentation. These changes raise operating costs for waste and industrial facilities in the region while offering small tax incentives for certified waste-reduction actions, so 2026 budgets, contracts, and compliance planning may need adjustment.

Slovenian Government Adopts Temporary CO2 Environmental Charge Levels for Fuels

In May 2026 the Slovenian government adopted a temporary decision reintroducing environmental charges on CO2 emissions from motor fuels, setting new per-unit rates that apply until 1 June 2026. This stabilises short-term fuel prices while signalling active use of carbon pricing, so fuel suppliers and fuel-intensive users should factor these levy levels and their June 2026 review point into cost planning and decarbonisation strategies.

Norway Proposes Further Delay Of CO₂ Tax On Natural Gas And LPG For Non‑ETS Chemical And Metallurgical Plants

Norway’s Revised National Budget 2026 proposes to delay CO2 tax on natural gas and LPG used by non-ETS chemical and metallurgical plants until 1 January 2027, while backdating earlier CO2 tax cuts for ETS-covered installations. If approved by the Storting, this extends the tax-free period for energy-intensive process industries and shifts timing and magnitude of carbon cost signals, with implications for fuel contracting, abatement investments, and competitiveness planning.

Norway Proposes CO2 Tax Changes for Industrial Installations in Revised 2026 Budget

Norway's Revised 2026 budget proposes to backdate CO2 tax relief for ETS-covered mineral products to 1 January 2026 and to delay the planned CO2 tax on natural gas and LPG used in non-ETS chemical and metallurgical processes until 1 January 2027. These moves temporarily ease carbon cost pressure on energy-intensive industry but lock in a clear 2027 start date for non-ETS fuel taxation, so affected companies should treat this as a short breathing space to update cost forecasts, contracts, and decarbonisation plans.

France: National Assembly Committee Adopts Draft Agricultural Protection Law With New Pollution Levy on Pesticides and Fertilisers

France’s National Assembly economic affairs committee has adopted a draft agricultural protection law that would introduce a high-rate pollution levy on hazardous substances in pesticides and phosphate fertilisers, alongside tighter import, exposure and water-use controls, with application from 1 January 2027. If enacted, manufacturers, importers and distributors will face significant new costs and data obligations tied to CLP hazard classes and specific substances such as flonicamid and cadmium, requiring early portfolio review, pricing strategy adjustments and alignment of water management and siting decisions with the new compliance regime.

Chile MMA Publishes 2025 Green Tax Emissions Compensation Results

Chile’s Ministry of the Environment has released 2025 results from the Green Tax Emissions Compensation System, showing a stabilising offset market with nine diversified projects delivering 1.68 MtCO2 of certified reductions across multiple regions. For companies subject to the Green Tax, this confirms a functioning compensation mechanism that can lower compliance costs by sourcing credits from renewable energy, waste-to-energy and electromobility projects while supporting national decarbonisation goals.

HMRC Technical Note Sets Electricity Generator Levy Rate Increase From 1 July 2026

HM Revenue & Customs has issued a technical note confirming that the UK Electricity Generator Levy rate will rise from 45% to 55% for electricity generated from 1 July 2026, with specific rules for accounting periods and instalment payments that span that date. Electricity generators subject to the levy must adjust tax planning and quarterly instalments to reflect higher liabilities from mid-2026, while the accompanying packaging waste data release simply updates EPR reporting statistics without changing existing obligations.

EU Parliament Transport Committee Backs Lower Road Tolls for Low-Emission Trucks and Buses

In May 2026 the European Parliament’s Transport Committee backed the Commission’s amended Eurovignette proposal, endorsing lower CO2-based road tolls for trucks and buses using efficient trailers and a temporary 75% toll reduction for low-emission heavy-duty vehicles, while aligning the regime with upcoming CO2 standards for new trucks and buses. If confirmed by Parliament and agreed with member states, this package would strengthen price incentives for more efficient vehicles and equipment in EU road freight and coach operations, and could materially change long-term cost structures and investment planning for fleet operators and tolling concessions.

Slovenia Extends Temporary Zero CO₂ Environmental Tax on Motor and Heating Fuels

In May 2026 Slovenia extended its temporary measure setting the environmental CO₂ tax on motor petrol, diesel and heating oil at zero until 1 June 2026, while keeping the standard rate for other fuels. This short-term relief lowers fuel costs and eases inflation pressure but weakens near-term carbon price signals, with implications for state revenues, energy-cost planning, and the trajectory of national climate policy.

EU Commission Proposes Temporary Excise Duty Reduction For Motor Fuels In Sweden (COM(2026)189)

In May 2026 the European Commission proposed a Council Implementing Decision allowing Sweden to apply a temporary 2.4 SEK per litre reduction in excise duty on gas oil and unleaded petrol used as motor fuels under the EU Energy Taxation Directive. If unanimously approved by the Council, this five‑month derogation would offer short‑term relief from high fuel prices for Swedish households and businesses while signalling the EU’s willingness to use targeted energy tax flexibilities in response to future price shocks.

Iowa Legislature Proposes Amendment S-5256 to SF 2490 on Oil and Gas Surface Access and Civil Penalties

In early May 2026, the Iowa House filed Amendment S-5256 to Senate File 2490, an oil and gas severance tax bill, to require explicit surface-owner consent for operations, create a contact opt-out mechanism, and introduce civil penalties for certain negotiation practices. If enacted alongside SF 2490’s new 6% severance tax and state pre-emption framework, these changes would materially strengthen surface owners’ leverage over oil and gas and natural hydrogen projects in Iowa and add planning and compliance complexity for exploration and production operators.

US Congress Introduces H.R. 8632 To Impose Excise Tax On PFAS

In April 2026, a US House bill (H.R. 8632) was introduced to amend the Internal Revenue Code to impose an excise tax on PFAS sales and provide a tax credit for PFAS removal from public water systems. If advanced, this would increase tax costs for PFAS while subsidising water-treatment investments, signalling rising federal pressure on PFAS producers and users to reduce reliance and address legacy contamination.
