Southeast Asiaâ€™s economy could lose trillions of dollars over the next 50 years if the region does not act to reduce carbon emissions significantly, a Deloitte report found.
In fact, the region is at a turning point, and can turn the cost into an opportunity, the report said.
If Southeast Asia steps up efforts on climate change and rapidly reduces emissions, it could achieve economic gains of $12.5 trillion in present value terms with an average GDP growth of 3.5 percent each year for the next 50 years, according to the consulting firm.
â€œThis potential future not only avoids the worst impacts of climate change, it also creates prosperous long-term economic growth for Southeast Asia and the world,â€ said Deloitte.
Failing to do so, however, could lead to global warming of more than 3Â°C by 2070, according to Deloitteâ€™s model. This could cost the region economic losses worth about $28 trillion in present value terms in the next 50 years, and reduce GDP growth by an average of 7.5 percent each year in the same period, according to Deloitteâ€™s forecast.
Southeast Asia prosperity â€˜at riskâ€™
Southeast Asia is home to half a billion people and has a gross domestic product of $3 trillion, according to Deloitte.
The region defined in the report as Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, The Philippines, Singapore, Vietnam, Timor-Leste and Thailand has seen a 5 percent to 12 percent average annual per capita GDP growth since the 21st century.
â€œUnmitigated climate change threatens to wipe out decades of hard-won economic growth in Southeast Asia,â€ Deloitte said.
â€œThe foundations of the regionâ€™s prosperity itâ€™s natural and human capital are at risk, and along with them each nationâ€™s standard of living, its prospects for future growth, its place on the global stage and the wellbeing of its people.â€
From agriculture to tourism, climate inaction will cause major disruptions as livelihoods are lost due to rising sea levels and natural disasters.
Here are the industries set to lose trillions by 2070:
Services industry could lose $9 trillion;
Manufacturing sector faces $7 trillion of losses;
Retail and tourism could collectively lose $5 trillion.
Together with construction, mining and gas, these sectors account for 83 percent of the regionâ€™s economic output, Deloitte said.
â€œThe impacts of a changing climate would be felt across Southeast Asian nations and industries, with some bearing the economic burden more than others,â€ the report said.
Time is running out
The United Nations has warned that keeping global warming close to 1.5Â°C above pre-industrial levels â€œwill be beyond reachâ€ in the next two decades unless immediate action is taken to reduce carbon emissions.
â€œThere is an urgency for countries and governments to act quickly within the next 10 years to circumvent irreversible damage from climate change,â€ said Philip Yuen, Chief Executive Officer of Deloitte Southeast Asia.
Southeast Asia needs to pivot from seeing global warming efforts as an optional cost, to seeing it as â€œan investment in a climate-driven transformation to a better future,â€ said Deloitte.
The amount countries spend on decarbonisation would be â€œalmost immediately offset by positive returns in the capital and technology,â€ the report said.
â€œWe have the opportunity to create a new engine for sustainable economic prosperity while at the same time preventing the worse consequences of a warming world.â€
