What Makes a Bank Ethical in 2025?
Ethical banks adopt strict exclusions for environmentally destructive sectors, disclose impacts transparently, and align with public concerns for nature and animal welfare. Real leadership means investing in sustainable food systems and refusing to fuel factory farming, deforestation, and poor animal welfare.
Why Choose a Nature-Friendly Bank?
Your money may be used to finance harmful and cruel industries, including factory farming, deforestation, and poor animal welfare practices.
Funding these sectors contributes directly to biodiversity loss, climate change, water pollution, and rising greenhouse gas emissions - all worsening the nature and climate crises.
Banks exposed to unsustainable industries face increasing financial risks that threaten your savings and pensions, and may undermine their fiduciary duty to act responsibly.
By choosing a nature-friendly, ethical bank, you ensure your finances support a sustainable future, protect your long-term savings, and help drive change towards responsible, climate-smart banking in the UK. Your actions can help build a greener, kinder financial system - because where you bank truly matters for nature, health, and society.
Top Three Ethical UK Banks
Triodos Bank
Triodos openly excludes factory farming and all industrial agriculture. Although it does fund some animal agriculture, it has stringent policies restricting lending to organic and regenerative farms with high animal welfare standards.
Triodos is among the few banks investing directly in food system innovation - including plant-based and alternative protein businesses - through its €72 million Food Transition Europe Fund.
Their impact reporting extends to biodiversity improvement, hazardous material avoidance, and jobs creation, making Triodos a trailblazer in transparent, planet-positive banking.
The Co-operative Bank
The Co-operative Bank’s Ethical Policy - reviewed by customers - refuses business involved in factory farming and animal testing, accepting only farms meeting high welfare standards.
No funding flows to intensive animal agriculture; the policy is unique on the UK high street and shapes the bank’s community and sustainability investments.
The Co-operative Bank does not have significant investments in alternative protein, but its mutual ownership and ethical screening provide a solid foundation for customers prioritising animal welfare and social responsibility.
Nationwide Building Society
Nationwide excludes all agriculture from its lending and investments - including factory farming, livestock, and animal testing - with one of the UK’s strictest business model decisions.
No funding goes to farming or animal testing, although there is no evidence Nationwide invests in plant-based food systems, as these are excluded along with the rest of agriculture.
Credible climate targets and full transparency in sustainability reports set Nationwide apart: customers can clearly see how their money avoids damaging impacts, with robust greenhouse gas disclosures and support for green lending.
Three UK Banks Harming Nature, Climate and Animal Welfare
Barclays
Barclays is the largest UK financier of industrial livestock, providing £28.2 billion to 55 major livestock firms between 2015 and 2022 - including over £6 billion to JBS, the world’s biggest meat producer.
Barclays has no group-wide exclusion policy on factory farming or animal agriculture, despite a series of high-profile scandals and global pressure; its funding enables animal cruelty, deforestation, Indigenous land invasions, and greenhouse gas emissions at scale.
75% of UK consumers are concerned about Barclays’s support for factory farming, and 80% want banks held accountable for funding animal cruelty.
HSBC
HSBC ranks among the top global financiers of factory farming, lending £19 billion to livestock and animal feed companies since 2015, with no exclusion for animal agriculture or animal welfare.
The bank’s financing has been linked to major polluters such as Cargill (Amazon deforestation, UK river pollution) and supports both conventional and intensive UK farming practices.
There is no evidence of HSBC investing in plant-based food systems, and NGO pressure is mounting for stricter divestment and support for nature restoration.
Lloyds Bank
Lloyds is the largest agriculture lender in the UK, backing livestock, dairy, and mixed-use farms—including those using factory farming—with no animal welfare policy or exclusion.
While Lloyds offers some sustainability initiatives (fee-free loans for agroforestry and peatland protection), it continues to support intensive animal agriculture, a leading driver of deforestation and climate emissions.
Lloyds is regularly ranked among the worst for potential links to animal cruelty and is facing calls to reform its lending practices.
