Chief Sustainability Officer (CSO)

A Chief Sustainability Officer (CSO) takes responsibility for the action that their organisation takes in relation to sustainability. They have a key role in driving sustainability both in their own organisation and more widely; they will need to ensure they are aware of the latest best practice, trends and initiatives to be able to make recommendations on future opportunities and risks.

How does this role align to the green agenda?

The CSO’s role is an important one in driving the green agenda forward and exerting influence both internally and externally.   

A CSO will always look to identify immediate opportunities to ensure their organisation or business adopts and encourages planet-friendly practices and behaviours. They are particularly concerned with the longer-term solutions for healthier environmental and economic outcomes. They will champion and actively pursue activities that do not contribute to global warming and climate change.  

Some of their key activities to support this will include:  

  • Ensuring that sustainability is given due prominence in decision-making at all levels of their organisation 
  • Promoting and encouraging best practice by engaging with their organisation’s employees, customers, investors, suppliers and wider stakeholders 
  • Using their knowledge and experience to advance the green agenda externally through engagement with policymakers and the widest possible audience in society at large.

Skills and capabilities

The sustainability sector is constantly evolving so a willingness to keep knowledge up to date and assess relevant risks and opportunities for the organisation is important.  

Technical knowledge

  • Requires comprehensive understanding of sustainability  
  • Excellent business management skills such as project management, and business case preparation to ensure alignment with the organisation’s other objectives 
  • In-depth knowledge of relevant regulations and standards across all areas of the organisation’s operations.  
  • Sector experience relevant to the organisation is often advantageous and in certain situations can outweigh some technical experience.   

Transferable skills

  • Management: the ability to manage people and lead a team is often important in larger organisations 
  • Analytical thinking
  • Problem reframing and resolution
  • Leadership: strong leadership experience is required to drive engagement and lead change internally and externally at a high level  
  • Relationship development: the ability to build strong, influential relationships is vital, through effective communication, both written and verbal 
  • Effective communication: able to communicate with authority and credibility 

A day in the life

A CSO’s typical day will vary considerably according to the size, sector and ownership structure of the organisation they are working with.  

The role provides an exciting opportunity for someone to drive the green agenda forward. 

However, it can be a challenging role that carries the responsibility to balance competing priorities and ensure sustainability initiatives correspond to wider business objectives. 

There is usually a large degree of autonomy that comes with a role at this level, and the capacity to be both proactive and self-motivated is important.

Typical duties and responsibilities include:
  • Focusing on the strategic level decision-making process, so working with senior executives, the management board and the non-executive team to align the organisation’s activities, mission and values with its environmental, social and wider sustainability objectives
  • Staying informed on what is happening ‘on the ground’, maintaining regular contact with employees at all levels of the organisation to ensure the sustainability strategy is understood and being effectively integrated into working practice
  • Communication with external stakeholders is a key part of the role, whether this entails attending investor presentations, overseeing the preparation of the organisation’s sustainability report, leading community-based initiatives, liaising with regulators and policy makers, or promoting sustainability across the organisation’s supply chain
  • Lead on the design and implementation of appropriate sustainability policies, procedures and best practice on sustainability related issues
  • Lead on communication of the organisation’s sustainability strategy and reporting on progress internally and externally
  • Providing guidance and support to the senior executives and wider company management to identify risks and opportunities presented by the current and future sustainability agenda and trends
  • Taking responsibility for ensuring compliance with all relevant laws, regulations and reporting requirements
  • Championing sustainability in the business and working with cross-functional teams to drive innovation and encourage continuous improvement
  • Identifying commercial opportunities to promote sustainable products and services.

Entry routes

There are various entry points to a role as CSO and there is not a ‘one-size-fits-all’ career path. Academic qualifications in a sustainability-related discipline are often required but a clear understanding of managing and running a business is just as important, and as a result CSOs regularly have a combination of technical and business-related qualifications.  

There are also a number of apprenticeships across leadership, business and sustainability which may be good foundations for this role.

It is not uncommon for long-serving individuals with extensive experience in other functions (e.g. finance, HR, operations, marketing) to move into a CSO role where their knowledge of the business is considered more important than their technical understanding.

To note: in England, Northern Ireland and Wales, it will typically take three years to complete a full-time, undergraduate degree. In Scotland, it typically takes four years. Apprenticeship courses vary in length, and also require an end-point assessment period. Please check this information on a case-by-case basis.

Potential career progression

The CSO role is usually the most senior sustainability specialist in an organisation. As such the next steps for someone in this role could include: 

Taking on a broader executive role such as Chief Operating Officer or Chief Executive Officer.

Moving to a similar role within another organisation to broaden experience. For example, setting up a new sustainability function in a less well-developed organisation, taking on a wider geographic remit, working with a larger or more diverse organisation, or working in an organisation with a different sector focus.

Providing consulting services or leading a sustainability focused start-up.

Relevant sectors

CSOs are needed in businesses across all sectors and organisations, within both the public and the private sector. They will usually combine a strong background in sustainability leadership with experience of a similar organisation to the one they are joining.
