Community displacement and the subsequent destruction of local economies took place as OCTP acquired approximately 257 acres of land for its operations. A July 2015 ENI Environmental Impact Statement states that “the households of Sanzule will be proportionally the most vulnerable to loss of livelihoods due to loss of access to 213 acres of farmland used by approximately 180 farmers”.

Meanwhile, the region’s fishermen have reported a severe decline in catch, describing how the lights from OCTP’s oil vessels draw fish towards them; the fishermen cannot follow due to a 500-metre, police-patrolled perimeter around these assets. Fishermen have also watched several species go extinct, while their nets fill up with the seaweed that is cut free during seabed drilling.

Living costs have risen as economic migrants arrive to take advantage of the new power plants. This rise has added extra financial pressure to locals who have lost their livelihoods.

The exacerbation of global heating is an unavoidable outcome of Offshore Cape Three Points, due to the project’s greenhouse gas emissions. The sources of OCTP’s operational emissions include the generation of power for construction, non-routine gas flaring, the use of marine support vessels and helicopters, and the filling, offloading and operation of export tankers.

Global heating is driving climate change, which is raising Ghana’s temperatures, shrinking and disrupting its rainfall patterns, increasing extreme weather events and fueling related disasters in the country, such as floods. More than 30 years of climate records show that the prevailing climatic conditions in Ghana have severely deteriorated and are likely to worsen, with increasingly severe and frequent droughts and floods predicted. Ghana is particularly vulnerable because its economy relies upon agriculture, forestry and energy production, which are all sensitive to changes in the climate.

A significant rise in local air pollution has been a consequence of OCTP’s construction. Released pollutants include nitrous oxide, carbon dioxide, sulphur dioxide and particulate matter, which were particularly attributed to earth moving, excavation and transportation. The project will continue polluting the air to run its floating storage and offloading unit.

The deterioration of marine ecology near the project’s drills is harming local sea life and therefore fishermen. Along with the movement of its vessels, OCTP’s seabed drilling can cause seawater turbidity, which negatively impacts the food supplies, spawning beds and gill function of fish. It is also likely that contaminants such as zinc and arsenic are seeping into the water.

Disappointing economic returns caused by excessive supplies of Ghanaian gas are a concern. Most of Ghana's LNG and energy projects have been contracted without accurate estimates for future demand, which is under threat. Ghana may have to slash its gas prices, which will cause rapid debt accumulation. Due to its so-called Take-or-Pay arrangements, Ghana National Petroleum Corporation must pay the private sector for any supplies that are not sold. This cost the corporation USD 168 million in 2019.
