ERM (consultancy)

ERM prepared the environmental statement for High Speed 1, Britain's first dedicated modern high speed train line, during the 1990s.^[12] In the 2010s, a consortium led by ERM was awarded the environmental impact assessment work for part of the High Speed 2 programme. Other consortium members included Mott MacDonald and Temple Group.^[13][14]

The company has also performed environmental studies for international railway projects. In the 1990s, ERM was contracted to perform studies of multiple railway development proposals in Hong Kong.^[15][16] During the early 2010s, it worked on an air quality assessment for the prospective expansion of a South African manganese ore mining line at the behest of Transnet.^[17] Around the same time period, ERM assessed the environmental compliance of a major train station on behalf of Brisbane City Council,^[18] and a new rail corridor in Tanzania.^[19]

ERM has frequently worked in the mining and energy sectors. The company produced the impact assessment for the Keystone Pipeline; critics accused it of having a conflict of interest by means of affiliation with proponents of the scheme.^[20] During 2021, it performed an environmental impact assessment in Guyana for the American oil and gas corporation ExxonMobil; its work on the project became a controversial matter due to alleged errors.^[21][22] ERM also prepared the impact assessment for the Dakota Access Pipeline despite having an alleged conflict of interest in the scheme.^[23] It also certified that the Batoka Gorge Hydroelectric Power Station, on the international border between Zambia and Zimbabwe, did not pose serious adverse effects on human settlement along the Zambezi River.^[24] ERM performed the environmental and social impact assessment for exploratory drilling in São Tomé and Príncipe during the late 2010s.^[25]

In 2022, the company was amongst several parties that were sued by a group of Houston residents that alleged misrepresentation, fraudulent concealment, wrongful death, and personal injury claims related to environmental pollution.^[26]

In 2019, ERM received funding from the British government for Project Dolphyn, a project focused on green hydrogen production from offshore wind power.^[27][28]
