What would be the result of zero tariffs for our British lamp manufacturer? They would be able to import their components with ease, but their exports would hit the same costs as one faces now when trading overseas.
Brexit carries a triple risk for the UK's farmers and environment. They risk losing Common Agricultural Policy subsidies vital to their livelihoods; being exposed to increased competition and tariffs in new trade deals; and the erosion of the UK's world-leading environmental protections.
Following the UK's decision to leave the EU, one of the most important things on the agenda is the renegotiation of our trade relationships with the rest of the world. There is mounting evidence that current trade rules are a significant barrier to achieving climate change goals. Brexit provides the UK with an opportunity to change this.
Who will make the rules on the global stage, and what rules will be there? It may take years to see whether the TTIP and TPP mean less power and future influence for China on the global stage, especially in relation to the United States. Perhaps, only time will tell.
The World Trade Organisation (WTO) has upheld a ruling that allows the European Union to ban seal fur imports on moral grounds. Canada fought desperately to have the ban repealed, but the WTO affirmed that nations have the right to reject seal products which they find morally reprehensible.
Meanwhile, the US continues to subsidise its own agricultural sector for crops like corn, wheat and soy, all of which are exported, all of which are associated with climate change: monocropping and the depletion of soil nutrition, reduction of soil capacity as a carbon sink and use for feed for Greenhouse Gas intensive meat production.
When I hear critics of the World Trade Organization, I'm increasingly reminded of the great moment in Monty Python's Life of Brian where a bunch of would-be Judean rebels ask "what have the Romans ever done for us?"... Fast-forward to the present day and criticisms of the WTO might well be met with a similar riposte.
It is safe to say that a watershed has been reached with the launch of the Transatlantic Trade and Investment Partnership
Ten years ago the launch of the Doha Development Round scored blanket news coverage on both sides of the Atlantic. The round of WTO negotiations named after the city where they took place were aimed at achieving no less than a complete reform of the way the global trading system works, levelling the playing field for developing countries by giving them access to developed country markets.
