While this country welcomed the new US$129.83 million terminal at the ANR Robinson International Airport, Crown Point, Tobago about a week ago, developmental economist Dr Marlene Attzs says the facility should not be seen as just another infrastructure project - rather it must be a tool for economic transformation, a catalyst for growth, job creation and sustainable development for the island.
In an interview with the Sunday Business Guardian, Attzs noted many other Caribbean countries have seen significant economic benefits from their investment in improved, modernised, expanded airport facilities. These Caribbean destinations, all heavily dependent on tourism, set benchmarks and opportunities for learning based on how they have used the airport expenditures to realise tangible gains in tourism revenues.
For example, she said, the expansion of Sangster International Airport in Montego Bay, Jamaica resulted in higher passenger capacity, increased flight frequencies and a surge in direct international flights. That investment, she said, contributed to Jamaica’s record-breaking 4.1 million visitors in 2023, bringing in US$4.2 billion in tourism revenue.
Further, Attzs explained a public-private partnership (PPP) model for the Jamaica airport expansion allowed private investors to fund airport improvements while the government focused on maximising tourism-related tax revenue.
In addition, the economist noted that the expansion of Punta Cana International Airport in the Dominican Republic turned it into the busiest airport in the Caribbean.
“Improved facilities encouraged more airlines to offer direct flights, increasing visitor numbers and boosting hotel occupancy rates. The government invested in infrastructure around the airport, creating new highways, resorts and business districts,” Attzs stated.
She also looked at Barbados, noting that the expansion of the Grantley Adams International Airport was driven by the need to accommodate larger aircraft and increased long-haul flights from Europe. Those new airport facilities allowed for better passenger experience, contributing to higher visitor satisfaction and repeat visitor arrivals
Turning back to Tobago, Attzs advised a similar approach, noting that expanding air capacity to attract more direct international flights could increase visitor arrivals, raise foreign exchange earnings and stimulate local business growth.
“A successful airport expansion can increase tourism’s contribution to GDP if aligned with national development goals. Airport development can drive tourism growth, attract foreign investment and create jobs, but only if managed strategically and sustainably,” Attzs said.
Cost-benefit analysis
What should a cost-benefit analysis (CBA) for the new Tobago airport look like?
Attzs explained this should assess economic, social and environmental factors to provide a well-rounded evaluation of its feasibility and long-term impact.
Regarding economic considerations, she said this should include both costs and benefits to the government, businesses and travellers.
Key costs should include:
* Capital expenses such as land acquisition, construction and infrastructure development; and
* Operational costs including maintenance, security, staffing and utility expenses.
On the revenue side, factors to consider include:
* Direct airport revenue from airline fees, landing fees and rental income from retail spaces.
* Tourism-driven revenue such as increased hotel occupancy (and related government taxes), as well as growth in local businesses like taxis, retail stores, and food and beverage establishments.
Social, environmental considerations
These Attzs emphasised should also be included in the cost-benefit analysis of Tobago’s terminal expansion so that a balance is struck between growth and sustainability.
She noted that despite the economic benefits, airport expansion projects in the Caribbean have faced environmental and social challenges, which Tobago should carefully manage.
Attzs advised that some key considerations should be that a modernised airport can result in higher carbon emissions, noise pollution and ecosystem disruption. She noted various Caribbean nations have tackled these issues through green airport initiatives:
(1) St Lucia’s Hewanorra International Airport expansion: St Lucia, heavily dependent on eco-tourism, ensured that its airport expansion met sustainability standards. The new design incorporated solar energy, rainwater harvesting, and carbon offset programmes to mitigate environmental impact;
(2) Barbados’ green airport strategy: Recognising the risk of coastal erosion and habitat destruction, Barbados included climate resilience measures in its airport expansion plans. The Barbados government imposed strict environmental regulations, requiring airlines and airport operators to reduce emissions and manage waste responsibly.
“For Tobago, it is crucial that airport expansion aligns with its eco-tourism brand. Sustainable features such as solar-powered terminals, water conservation systems, and low-emission ground transport can ensure that tourism growth does not come at the cost of environmental degradation,” Attzs added.
Further, she said, the airport expansion also should factor the impact on the community to ensure benefits accrue to the local community, citing that one of the biggest concerns with airport expansion projects is ensuring that local communities benefit from increased tourism activity.
Tool for community development
Noting some examples of Caribbean countries that have used airport expansions as a tool for community development, Attzs said these include:
(1) Jamaica’s inclusive tourism model - The expansion of Montego Bay’s airport was paired with training programmes for locals, ensuring that tourism jobs were accessible to Jamaicans. The government promoted small business participation, encouraging local vendors to set up shops in airport terminals;
(2) Dominican Republic’s local integration - The expansion of Santo Domingo’s Las Américas Airport involved collaboration with local taxi drivers, tour operators, and restaurants. Small and medium enterprises (SMEs) benefitted from increased tourism flows, creating a multiplier effect in the economy.
Further, Attzs recommended that the Tobago’s airport expansion should include a local business participation plan, ensuring that local hotels, restaurants, and tour operators benefit from increased visitor arrivals; employment opportunities are prioritised for Tobagonians, reducing economic inequality and infrastructure improvements (roads etc) also serve the local population.
Additionally, she said a modernised, larger airport terminal in Tobago would likely increase flight traffic, supporting Government’s tourism expansion goals. However, Attzs cautioned this could also result in negative environmental impacts, particularly in terms of:
· Noise pollution, affecting residents and businesses in close proximity to the airport.
· Air quality concerns from increased aircraft emissions.
A relevant case study, Attzs said, is the Heathrow Airport expansion in England, where noise pollution became a major issue, particularly during the development of Terminal 5 (T5) and discussions around a third runway.
She also stated that nearby communities, such as Hounslow, were significantly affected by increased aircraft noise, leading to significant public outcry.
Finally, Attzs emphasised a thorough CBA should weigh these economic opportunities against the environmental and social trade-offs, ensuring that a new Tobago airport delivers sustainable benefits while addressing potential negative externalities for local communities.

At the official opening of the new facility on Saturday, then Finance Minister Colm Imbert shared that on a cost per-square-metre basis, the new Tobago terminal was delivered at approximately US$6,000 per m², significantly below the Caribbean regional average of roughly US$11,200 per m² and the global average of approximately US$13,800 per m².
“In other words, we have built more for less. The story is similar when we look at the cost per passenger: our project’s cost works out to roughly US$53 per annual passenger capacity, whereas comparable airport projects average about US$177 per passenger,” he said.
Imbert added the facility was designed to be eco-friendly and energy efficient.
It incorporates features, such as solar panels, energy-saving LED lighting, and highefficiency climate control systems, to reduce energy use.
Water conservation measures, including rainwater collection and low-flow plumbing, have also been implemented to reduce water wastage.
Sustainable building materials and strict waste management were also applied to minimise the environmental impacts.
National Infrastructure Development Company (Nidco) chairman Herbert George who also spoke at the opening ceremony, said the project, managed by Nidco, began on July 18, 2020 and was expected to be completed in July 2022, at an original contract sum of US$128, 663, 741.
The final contract sum, he said, will be determined following the outcome of the evaluation of claims submitted by the contractor, China Railway Construction Caribbean Company Ltd.
