Rivers play an important role in any city, in terms of the economy, transportation of people and goods, and the wellbeing of local residents. In recent years, the maritime sector has become increasingly aware of its environmental and social impacts.

The Thames Green Scheme aims to demonstrate the environmental benefits of Thames operations; and to recognise the early adopters of new technologies and/or fuels that will reduce emissions to air. It can also be used a as tool to support the inland waterways operators community achieve the goals set out in:

  • the updated Air Quality Strategy (AQS) for the tidal Thames 2020,
  • Clean Maritime Plan published by Department for Transport in 2019; and
  • the UK government’s Net Zero by 2050 commitment.

Tier system

Operators can submit the data after registering for the Green Scheme. We will be looking for data about your vessel fleet and your company’s environmental commitments to generate your overall score.

The overall score and the average vessel score determines which Tier – Bronze, Silver, Gold, Platinum, or Diamond, will be awarded to you (as shown in Table 1) .

The Overall Score

The overall score (out of a maximum 100) is generated for each organisation, based on their corporate score (A) and the average vessel score (B) – more on A&B below.

A corporate weighting factor (Wc), ranging between 0.3 – 0.5 will be applied on the corporate score when calculating the overall score. This will take account of the size of the corporation, i.e. the number of employees and the size of fleet in order to reflect the availability of resources and relative impact on society.

For example, an organisation with a small number of employees to vessels ratio will have a slightly larger weighting on their average vessel score relative to an organisation with a large number of employees to vessels ratio.

Table 2 Corporate Weighting factor, Wc

Wc Number of employees-to-vessels ratio
0.30 < 3.8
0.35 ≥ 3.8 & < 6.5
0.40 ≥ 6.5 & < 9.3
0.45 ≥ 9.3 & < 12
0.5 ≥ 12

A. The Corporate Score

A company’s level of engagement with sustainability and other ESG (environmental, social and corporate governance) matters will be reflected in the organisation’s performance.

  • In this part of the assessment, participants will be evaluated based on their approach to the following areas:
  • Environmental management: e.g. do you follow the management systems standard ISO 14001, use renewable energy, etc.,
  • Waste and litter management: e.g. what provision is there for waste recycling, storage
  • Oil Spill management: e.g. spill kit, report
  • Nuisance complaints management: e.g. what steps are in place to manage noise, wash, black smoke, and light pollution
  • Carbon footprint: e.g. is a carbon footprint calculated, are there reduction targets and action plans
  • Involvement and awareness of wildlife conservation, new green technologies, and litter: e.g. engagement via social media, newsletter, research collaboration and sponsorship, new technology trials

B. The Average Vessel Score

In this section, each operating vessel, including freighter, workboats, service boats, tugs, Class V passenger vessels, dredgers, barge, tankers, will be evaluated based on the following areas:

  • Air quality: e.g. engine standard, fuel type & emission abatement technologies
  • Energy efficiency: e.g. behavioural and technical modifications to be energy efficient
  • Black & greywater management, if applicable: e.g. reducing the generation of black and greywater
