Environment Report

The Port of Milford Haven is a diverse organisation. Its complex range of activities have a broad spectrum of environmental aspects and potential impacts. The Port takes its environmental responsibilities seriously and seeks to ensure that its activities are as sustainable as can be practically achieved. Considerable monitoring, liaison and management activities are invested in maintaining the special qualities of the Milford Haven Waterway and its surroundings, and in improving the Port’s environmental performance.

Oil Pollution Incidents

The prevention of hydrocarbon pollution is a central focus of the Port’s environmental performance, as would be expected in an environment with such high levels of hydrocarbon transport. Accordingly, all pollution incidents are taken seriously, whatever their magnitude. In 2017, eight pollution incidents were reported, an increase of three on the previous year. Each represented extremely low volume and were of minimal significance, so the trend of increase over the last three to four years indicates a rise in reporting rather than an increase in the quantity of hydrocarbons spilled.

The Port welcomes this increased vigilance as a powerful way of reducing the likelihood of a significant spill.


The EU Waste Framework Directive requires all Member States to implement measures to ensure that, from 2015, four key waste materials are segregated from other waste for recycling.

All of the waste generated by the Port adheres to the Waste Hierarchy, and, as a matter of default, is separated into waste streams at source where Technically, Economically, and Environmentally Practicable (TEEP). In 2017, the Port achieved an average monthly recycling rate of 86%. This is achieved partly by streaming at source and partly by further segregation undertaken by the Port’s waste management contractors.

There has been a recent rise in the level of public awareness of the effects of waste, and especially plastic waste, on the marine environment. The Port has for many years been committed to the reduction of marine litter and has supported disposal of marine waste encountered by fishermen through the Fishing for Litter scheme. The Port has also maintained active involvement in the Welsh Government’s Marine Litter Task and Finish Group, now named the Welsh Clean Seas Partnership.

External Liaison and Engagement

TPort of Milford Haven's external liaison groupshe Port is an enthusiastic participant in various stakeholder engagement activities across Wales (the list of groups engaged with by its Environmental Manager can be seen opposite). The Port seeks to maintain an open and positive working relationship with  stakeholders, including Government colleagues, and is committed to continuing this engagement.

Marine Protected Area Management

As part of its commitment to the good environmental management of the Milford Haven Waterway, the Port provides hosting and in-kind facilities for the Pembrokeshire Marine Special Area of Conservation (SAC) Officer. The SAC Officer is independent of the Port and reports to a Relevant Authorities Group, whose members collaborate to achieve good management of the SAC. As a result of increasing interest in marine environmental issues during 2017, the SAC now has an online presence on Facebook and Twitter to assist public engagement with this important marine protected area. The Port supports the SAC Officer in this endeavour.

Carbon Footprint

The Port’s carbon footprint arises from many sources: marine craft fuel use, plant and vehicle fuel use, indirect energy emissions, water, heating fuel and gas use. Combined, these all contribute to the amount of CO2 released as a result of the Port’s activities. One of the Port’s scholarship students was tasked to redesign the approach taken, and tools used, by the Port to calculate its carbon footprint and this approach has now been adopted. When comparing 2017 figures to earlier figures, it is important to note the change of methodology (alongside updated inputs that reflect changes in port plant and activities).

In 2017, the Port’s CO2 emissions are estimated at a total of over 3,900 tonnes. The largest single sector of emissions generation remains marine craft, followed by indirect energy emissions.

Photo-Voltaic Generation

In 2017, the Port continued to generate zero-carbon energy from its range of photovoltaic panels installed across port properties and from the large solar array at Liddeston Ridge. The total generated by the building-mounted panels was over 570,000 kWh, with the solar array generating over 4,500,000 kWh. The carbon emissions saving embodied in this generation equates to over 1,800 tonnes, which is offset against the carbon footprint arising from Port activities.
