New research has found that damage to the natural environment is slowing the UK economy, and could lead to an estimated 12% reduction to GDP in the years ahead - larger than the hit to GDP from the global financial crisis or Covid-19.

The first-of-its-kind analysis quantifies the impact that nature degradation, both domestically and internationally, could have on the UK’s economy and financial sector, and highlights that these risks need to be acknowledged and addressed to strengthen the UK’s economic and financial resiliency.

The work was led by the Green Finance Institute (GFI), with a technical team involving the UK’s top researchers: the Environmental Change Institute at the University of Oxford, the University of Reading, the UN Environment Programme World Conservation Monitoring Centre (UNEP-WCMC), and the National Institute of Economic and Social Research (NIESR).

The deterioration of the UK’s natural environment could lead to an estimated 12% loss to GDP, according to new analysis. In comparison, the financial crisis of 2008 took around 5%1 off the value of the UK GDP, while the Covid-19 pandemic cost the UK up to 11%2 of its GDP in 2020.

This is according to a first-of-its-kind analysis, led by the GFI, with input from the scientific and financial community, as well as direction from the Department for Environment, Food and Rural Affairs (Defra), HM Treasury (HMT) and the Taskforce on Nature-related Financial Disclosures (TNFD), and input from the Financial Conduct Authority (FCA). The report - Assessing the Materiality of Nature-Related Financial Risks for the UK - analyses the impact of the degradation of natural ecosystems, both domestically and internationally, to the economy and financial sector in the UK.

Nature-related risks are as detrimental or more to the economy as those from climate risks, the analysis shows. Yet, while the economic costs of climate change are becoming increasingly accepted, the risks posed by nature degradation amount to a material cost that has not been sufficiently factored into financial and business decision-making. This is leaving the economy and financial sector exposed, while these risks continue to rise unchecked. The UK is one of the most nature-depleted countries in the world - three quarters of the UK has a high level of ecosystem degradation, with risks to financial services and the wider economy as a result. The analysis shows however, that half of the UK’s nature-related financial risks originate overseas.

Dr Nicola Ranger, Director for Greening Finance at the UK Integrating Finance and Biodiversity Programme and the Environmental Change Institute, University of Oxford, one of the lead authors of the report said: 'Over the last decade, Central Banks and financial institutions woke up to the risks posed by climate change and we’ve seen meaningful steps to address them, including mandating disclosures, and beginning to shift capital flows toward green sectors and technologies. With this report, we comprehensively demonstrate that risks from environmental degradation and biodiversity loss are at least as severe and urgent, and indeed that if not addressed, will double climate change losses.'

Michael Obersteiner, Director of the ECI, added: 'In an interconnected world, it is no surprise that cause and effect can go both ways, and that international issues can negatively impact our economy. We typically view nature as the victim, which suffers from competition for land and the effects of climate change. However, this report highlights the ways in which problems from the natural world can come back to cause difficulties for our economy.

'Some of these issues, such as crop, livestock and human diseases are long standing threats, likely exacerbated by a changing climate, but some, such as wildfires are playing out at larger, more impactful scales as our world changes. At both the national and international level, we are forced to consider that limiting land use and climate threats to biodiversity is in our own interests, as well as that of nature itself.'

Within the analysis, a new inventory charts these domestic and international nature-related risks to the economy, many of which are not currently captured in national risk assessments. The inventory captures financial risks arising from the deterioration of nature and biodiversity, including: soil health decline; water shortages; global food security repercussions; zoonotic diseases that pass from animals to humans, like bird flu, swine flu, and Covid-19; and antimicrobial resistance, where bacteria and viruses no longer respond to medicines; as well as transition and litigation risks.

Some sectors in particular face higher levels of nature-related financial risk. Highlighted in the analysis are agriculture, manufacturing, and utilities. For example, the agricultural sector faces risks associated with water, climate regulation, soil quality, and pollution which could impact food production. The utilities sector is dependent on surface water for cooling power stations, and any constraint in water supplies could impede production and raise energy prices.

These impacts on the real economy will also have a material financial impact on banks and other financial institutions. The analysis estimates that some banks could see reductions in the value of their domestic portfolios of up to around 4 - 5% in some cases. Noting that these estimates are likely to be conservative, this indicates that nature-related risk will not just impact the economy, but potentially financial resilience.

Demonstrating the significance of the risks, these findings present an opportunity for swift action from governments, central banks, regulators and the financial sector to proactively manage nature-related risks and to position the UK as a global leader in addressing them. For businesses there are early-mover advantages for those that act to improve and support resiliency, particularly within their supply chains.

The GFI and technical team make several recommendations for the public and private sectors. These include disclosures of nature-related risks and taking urgent action to meet the targets included within the Global Biodiversity Framework (GBF).

Lord Benyon, Minister of State at the Department for Environment, Food and Rural Affairs, said: 'Nature underpins the health of our economy, and it is under threat from a global nature crisis. The responsibility to conserve nature lies with all sectors and sections of society, and green finance has a crucial role to play. The findings in this report will help people and institutions across the corporate and finance sectors understand that it is in their own interests to go further and faster for the planet to protect it for future generations.'

Baroness Vere of Norbiton, Parliamentary Secretary at HM Treasury, said: 'Nature sustains economies and livelihoods, that is why the Government’s Green Finance Strategy incorporates both nature and climate adaptation. It is in the interests of corporates and financial institutions to prepare for the global transition to a net zero, resilient and nature positive economy, so I welcome this report.'
