Brexit will have a major impact on all aspects of environmental and energy law, with a massive volume of primary and secondary legislation of critical importance expected in the next few years.

This will include :

European Union (Withdrawal) Bill
Nuclear Safeguards Bill
Sanctions and Anti-Money Laundering Bill
Trade Bill
Taxation (Cross-Border Trade) Bill
Customs Bill
Migration Bill
Agriculture Bill
Fisheries Bill
Withdrawal Agreement and Implementation Bill (announced 13 November 2017)
1000+ Statutory Instruments
Revisions to International Treaties & Conventions, and Trade Agreements
Revisions to UK relationship with key EU institutions or establishment of new UK institutions
Devolution legislation in Scotland, Wales, Northern Ireland
Post-Brexit legislation
New initiatives, e.g. Michael Gove announcement of legislation to replace EU enforcement of legislation

The impacts of this will vary greatly between industry sectors. For example the nuclear industry will be concerned about the replacement of Euratom Treaty safeguards with national arrangements, the chemicals industry will be heavily affected by UK arrangements to replace the EU REACH chemicals Regulation and the relationship with the European Chemicals Agency, other industries with lengthy international supply chains such as aerospace and automotive companies have real concerns about customs arrangements for imports of parts, and many industries are concerned about access to skilled workers under immigration controls.

William can help clients assess and navigate through the key impacts of legislation on their operations, identifying and analysing the points that matter most to them and helping to ensure that they are as well prepared as possible. He is working on preparing Brexit Legislation Briefings to present for clients in-house.
