The UK is now out of the EU and we have lost many of the environmental protections that came with membership. If we are to avoid any risk of a return to being the “dirty man of Europe”, those protections urgently need to be restored and strengthened.

The UK is one of the most nature depleted countries in the world. In the course of my lifetime, populations of some of our most important wildlife have plummeted by over a half, and the situation is getting worse. According to the RSPB, the government is failing to meet 17 out of 20 UN biodiversity targets. This must be reversed, fast.  

The Environment Bill presents a perfect opportunity for the government to show it means to follow through on its pledge to “be the first generation to leave the environment in a better state than that we inherited”.  

Early signs do not look good. As currently worded, the Bill would allow action to be put off until it’s too late. There needs to be a mechanism for making sure new targets are put in place immediately, and to make interim targets legally binding, so that we don’t wait until the natural world collapses even further before anything is done about it.

The Bill enshrines five important environmental principles in law, including “polluter pays”. However, as currently drafted, the secretary of state needs only to pay “due regard” to an as yet unpublished policy statement on these principles, rather than to “act in accordance with them”. That means their legal status is weaker than when we were members of the EU – despite all those assurances that there would be a “Green Brexit in which environmental standards are not only maintained but enhanced”.

Moreover, the principles don’t apply to all public bodies, and – astoundingly – two critical ministries, the MoD and the Treasury, are completely exempt, even though it is economic decisions which often drive environmental destruction.

Then there is enforcement. The Bill sets up a new Office for Environmental Protection to replace the enforcement powers that were previously provided by the European Commission. But if a watchdog is to have real teeth, it has to be capable of holding the government to account, with full independence and powers to prosecute and impose financial penalties. The OEP is not sufficiently independent, and thanks to a new clause inserted by the government at committee stage, can be “guided” by the secretary of state, which risks turning it into a lap dog.

There are plenty of other weaknesses in the Bill, from its failure to include a statutory deforestation target to the lack of an overall goal of halving the UK’s global footprint.

But there is a more fundamental flaw: that even the very best environmental policies will not be up to the job of protecting and restoring nature, unless we face up to the fact that our current economic model is broken, and set about fixing it. It is driving ecological breakdown, without delivering the wellbeing and basic support that people need – whether sufficient food, good health, housing or income.

A recent UN report on the state of nature explicitly identified the growth of the global economy, and in particular the growth of material consumption in wealthy nations, as one of the major driving forces behind the collapse of nature. There are countless other reports which say that endless economic growth is incompatible with tackling the climate and ecological crises.

The OECD issued a report last year warning that patterns of economic growth were now generating “significant harms” including “rising inequality and catastrophic environmental degradation”. It called for new goals for the economy that address today’s greatest challenges.  

It’s not enough to leave the environment in a better state than we inherited. We need to leave it in a state that will sustain people’s lives for generations to come. The way to achieve this is with an economy focused on wellbeing. The Environment Bill should be the starting point.
