Cetacean population restoration and carbon removal
Looking ahead to the future, TECO will continue its search for concrete carbon removal methods on the foundation of the joint international goal of carbon neutrality by 2050. Generally speaking, afforestation is the most direct method of carbon removal. However, it is not easy to find a large-scale site for afforestation in Taiwan due to the shortage of land and high population density. In view of the fact that Taiwan is surrounded by oceans, the identification of a marine carbon fixation method is more meaningful. Starting this year, TECO has initiated discussions and planning with NGOs and academic organizations regarding restoration of cetacean populations.
An IMF research report reveals that each whale sequesters 33 tons of CO2 on average, which is equivalent to the carbon absorption of 2,750 trees (each tree absorbs 12kg of carbon each year). Overall whale populations are now less than one-fourth what they once were. The restoration of whale population is therefore of paramount importance. Whales also create floating plants since their feces contain substances (iron and nitrogen) required for the survival of various species of such plants. The floating plant ecosystems all over the world are equivalent to 1.7 trillion trees or four Amazon rainforests
Taiwanese academic circles currently still lack clearly defined numerical models for cetacean populations in seas surrounding Taiwan and their carbon sequestration capacity. They are, however, aware of the fact that known large-sized whale species such as sperm whales and humpback whales and other medium-, and small-sized whale species in deep sea waters play a key role as carbon sinks. The average weight of a large-sized whale is equivalent to that of 200 dolphins. Each dolphin also has potential carbon fixation effects equivalent to 14 trees each year. The preservation of thousands of leaping dolphins in the Pacific Ocean can therefore also help slow down climate change and global warming. An even larger carbon fixation capacity results if we take into account the daily food intake of 25kg (5% of their weight) and the floating plants generated hereby.
TECO firmly believes that the restoration of cetacean populations is a concrete carbon removal method perfectly suited for Taiwan. The Company therefore plans to invest more resources into research and ecological conservation. In addition to sponsoring relevant activities in protected areas, the Company is committed to developing core technologies including corrosion-resistant electrification equipment for ecological conservation facilities on land, drones for dolphin observation, and powertrain systems for underwater vehicles in the future. The goal is to set an example for others to emulate and turn Taiwan into a global leader in the field of climate change action and thereby fulfill TECO’s pledge to carbon neutrality
