If your charity provides an employee pension, the first step will be to assess your current pension scheme through an ESG lends. You can check with your pension provider on its ethical investment policy.
If you are unsatisfied with the ESG criteria of the pension scheme, ask your provider if there are any alternative ethical options that your employees could switch too.
It can sometimes be difficult to gather the relevant information from your pension provider. If you feel your provider does not have an adequate ethical policy and cannot provide you with a satisfactory alternative option, you can look into changing pension providers. How quickly you can do this will depend on the specific contract you have with your provider.
An independent financial adviser (IFA) can help to identify pension funds which incorporate ESG issues.
