The referendum is due of course, on 23 June 2016 and it will take a number of years after that to conclude Brexit negotiations if indeed that is the outcome. The legal consequences are complicated, and Treaties, Directives, Regulations and court judgments may cease to apply to the UK unless specifically provided for in UK law. This is especially pertinent in the area of environmental law, as many principles and obligations in our national law stem from EU legislation.

Whilst the precise nature of the UK-EU relationship after Brexit cannot be known, it is possible to speculate a little about how a general Brexit might affect our national, environmental legal regime. This briefing looks at the impact of Brexit on certain environmental laws in the UK. We do not consider here the impact on other countries, in particular those remaining in the EU, but the International Environment Team here at Bird & Bird is ready to answer any such queries. We also address only those environmental laws that are most relevant to our clients generally, and so do not consider here the impact on (amongst others) air quality, agriculture, fisheries and habitats legislation– again, we are of course happy to answer any queries on these issues if helpful.

Climate change regulation

The UK government has its own legally-binding climate change (emission reduction) targets, through the Climate Change Act 2008, and its own carbon reduction schemes, such as the climate change levy and CRC Energy Efficiency Scheme – it is generally considered that these are unlikely to change in the event of Brexit. Likewise, whilst the EU Emissions Trading System raises some questions, for example, on issues such as the validity of EU ETS allowances if the UK leaves the EU, given our own national implementation measures and associated compensation schemes, it seems more likely than not that the UK will continue with some form of emissions trading scheme if Brexit occurs, whether that be the EU ETS or a national scheme linked to the European one.

There are also questions over the UK’s international obligations, including the UK's commitment to the UN Framework Convention on Climate Change and recent Paris Agreement (as this is currently caught within the EU's commitment) – a particular concern here is the reduction in influence that the UK would have over international climate change negotiations and agreement.

Finally, whilst EU legislation, such as the Renewable Energy Directive, has undeniably driven an increase in renewable generation in the UK, other national and international obligations (see above) mean low carbon generation should form part of the UK government's future policy – it is just difficult to speculate what part renewables will play in that.

Waste management

EU legislation is prominent in this sector. Recycling targets, the waste hierarchy and definition of waste are all derived from EU legislation and policy. The UK's waste management sector is strong (including significant exports of recyclate to other Member States). It might be assumed that the UK government wishes that to continue and so would not drastically alter waste management law following Brexit. Questions have however, been raised about compliance with recycling and waste reduction targets in the medium to long-term and this could undermine long-term planning and investment in waste infrastructure. There are also concerns that the Brexit debate is lessening the UK's influence in the EU now, and important policies such as the Circular Economy are being shaped without significant UK input.

Product compliance – REACH, CLP and RoHS

The REACH and Classification, Labelling and Packaging Regulations both have direct effect in the UK (although the Directive restricting hazardous substances has been implemented into national law). Withdrawal from the EU would potentially mean the UK is not legally obliged to adhere to the REACH and CLP Regulations. However, in order to:

  • Ensure access for UK exports into the Single Market;
  • Meet commercial requirements, such as supply chain obligations; and
  • Maintain protection from hazards for end-users,

it is reasonable to speculate that the UK government or industry will ensure continued adherence to the standards and obligations within these regimes (albeit with no ability to input into the future direction of EU regulation on the chemical industry).

Domestic legislation – contaminated land regime

There is some UK environmental legislation that is purely domestic – such as the contaminated land regime in Part 2A of the Environmental Protection Act 1990. It is difficult to see why or how Brexit would lead to any direct change.

Conclusion

There are concerns that a complete Brexit may result in less environmental protection in the UK, in particular that it would allow other economic and competitive arguments to push for precedence over environmental protection and standards, especially in the event of any economic downturn, and it may be politically difficult to resist that pressure. Brexit would also most likely mean that the UK has less influence in the direction of international agreements and laws. However, Brexit may allow freedom to adjust environmental legislation to a more UK-specific regime. The government has said little about the exact impact of Brexit on our environmental legal regime. Perhaps the only thing that is certain is that Brexit will have a far-reaching and complex effect on our environmental legislation, and that long-term uncertainty does not encourage green investment.
