San Carlos City in Negros Occidental, the Philippines, was once home to one of the country’s biggest sugar mills. But as the growth of the sugar industry has slowed since the 1980s, the city has sought alternative means of generating revenue. It has harnessed one of its most abundant natural resources: sunshine.
As a coastal city with a deep natural mangrove harbour, San Carlos is more resilient than most Philippine cities to extreme weather. And with limited cloud cover, the city enjoys more sunshine than other parts of the country, so has plenty of renewable energy potential.
As such, San Carlos is shaping up to be the Philippines’ renewable energy hub.
In 2014, a 45-megawatt solar plant—one of the country’s first solar facilities—was built in San Carlos City by renewable energy company San Carlos Solar Energy. In 2016, a 59-megawatt solar power plant went into operation. The plant is owned by San Carlos Sun Power Inc., a subsidiary of AboitizPower, one of the country’s leading renewable energy developers.
Besides solar power farms, San Carlos City is home to one of the country’s biggest biomass and bioethanol plants.
While implementing renewable energy projects may seem costly at the onset, in the long run, it comes with a number of co-benefits including job generation, water security, and better air quality to name a few.

But according to Arthur Batomalaque, assistant head of the City Environment Management Office (CEMO), being a top destination for renewable energy development is not enough to make San Carlos City “green.”
“As the city’s economy continues to grow rapidly, we will need to continue to engage in initiatives that protect our environment,” Batomalaque said.
As such in 2017, San Carlos City launched a trailblazing project: it conducted a community-level greenhouse gas (GHG) emissions inventory.
Using the Global Protocol for Community-Scale GHG Emissions Inventories, a tool jointly developed by non-government organisations ICLEI-Local Governments for Sustainability (ICLEI), C40 Cities, and think tank World Resources Institute (WRI), San Carlos City embarked on a project that sought to calculate the emissions from its commercial and residential buildings, transport, waste, water treatment, agriculture, and industry.
The inventory, using 2015 as its baseyear and completed last year, revealed that the city’s total emissions amounted to 88,330 tonnes of carbon dioxide from its energy, transport, agriculture, and waste sectors. This is equivalent to more than 39,463 tonnes of coal burned.
Batomalaque said in an interview with ICLEI that a GHG inventory can be used as a basis for local government plans to reduce emissions.
“The completion of the city’s GHG emissions inventory is a milestone for us. This is in line with our goal to become a green city,” he said.
What renewable energy and the 1.5 degree threshold means for Philippine cities
The National Climate Change Adaptation Plan, drafted in 2011 by the country’s Climate Change Commission, states that if climate change related disasters become more frequent, the Philippines will be left more vulnerable due to exacerbating factors of population growth, lack of preparation, and inadequate risk management.
In 2015, the Global Risk Index identified the Philippines as the most at-risk country from climate change.
A warmer world threatens agriculture, which makes up a fifth of the Philippine’s total economic activity and provides jobs for almost 30 per cent of the population. Many cities in the Philippines, like San Carlos, have rural communities where agriculture is the main economic activity.
Coastal cities like San Carlos also depend on the ocean for their food and livelihood, and if global temperatures increase beyond 1.5 degrees Celsius, as they are predicted to at the current rate of greenhouse gas emissions, marine life will be gone as we know it by 2100, according to a report by Climate Analytics.
Recognising that San Carlos City is highly vulnerable to climate impacts, its local government is looking to lower emissions by embracing clean technology.
“The energy sector is one of the main drivers of cities’ economic activities and GHG emissions. As such, there is clamor for clean energy sources,” ICLEI SEAS regional program manager, Ranell Dedicatoria said.
“While implementing renewable energy may seem costly at the onset, in the long run it comes with a number of benefits including job generation, water security, and better air quality,” he said.
