Taking stock of nation's climate finance
In its "State of the Global Climate 2024" report, it said last year was "likely the first calendar year to be more than 1.5C above the pre-industrial era, with a global mean near-surface temperature of 1.55 ± 0.13C above the 1850-1900 average".
This makes 2024 the warmest year in the 175 years that have been observed, according to this seminal report which was released in March.
The record-breaking year "underlined the massive economic and social upheavals from extreme weather and the long-term impacts of record ocean heat and sea-level rise".
Leading concerns
Thailand serves as a microcosm of this urgent need.
The country has already ranked 30th in this year's list of countries that are most vulnerable to climate change, according to human rights organisation Germanwatch.
The United Nations Economic and Social Commission for Asia and the Pacific (Unescap) estimates that Thailand's average annual damage from climate change will amount to almost 1 trillion baht, or 6.6% of the country's GDP per year, under the 2-degree scenario.
The cumulative damage of climate change on Thailand's agriculture sector alone is estimated to be between 17.5–83.8 billion baht per year between 2021-2045.
Naturally, Thailand needs significant investments in climate mitigation to keep up its commitment on the global stage.
In 2024, the Department of Climate Change and Environment estimated that a 30% reduction in carbon emissions by 2030 would require a 5 trillion baht investment in climate finance, while a 40% reduction would require an investment of 7 trillion baht.
Tracking finance flows
One major drawback for Thailand is the lack of any sense of urgency as well as the financial resources for both climate mitigation (to lower greenhouse gas emissions) and climate adaptation to reduce the negative impacts of climate change.
Thailand still lacks a clear picture of the current climate finance flows in the country.
As Climate Finance Network Thailand (CFNT) was founded in 2024 with the aim of catalysing more meaningful climate finance in Thailand, we took it upon ourselves to compile as much data from publicly available sources to construct a public "Climate Finance Tracker" (henceforth referred to as the "Tracker") for Thailand -- akin to the Global Landscape of Climate Finance report produced annually by the Climate Policy Initiative (CPI), the US-based organisation that focuses on climate finance and policy.
We focus on two main activities: climate mitigation and climate adaptation.
We found sources of climate finance come from various areas such as government bodies, multilateral development banks, national and multilateral climate funds, state-owned enterprises, specialised financial institutions, domestic public funds, and international financial institutions. These funds are typically directed through official development assistance (ODA), concessional loans, grants, or public investment programmes.
On the other hand, private climate finance also comes from the private sector, for example, commercial financial institutions, corporations, impact investors (including philanthropy), institutional investors, and other non-state actors.
It includes investments aligned with clear climate-related objectives through mechanisms such as green bonds, green loans, and blended finance.
One key principle used by the CPI that we adopted for our Tracker is the focus on direct investment aligned with climate mitigation and adaptation efforts within the country.
In line with the CPI's methodology, the Tracker also excludes any financial flows that do not represent new investments targeting climate-related outcomes. Investments we excluded from our calculation are secondary markets, refinancing, the transfer of ownership of existing assets, and public subsidies that are primarily designed to reimburse initial investment costs, such as those supporting private research and the development of new technologies.
Like the CPI, we exclude "carbon emissions lock-in" projects. This refers to cases where investment clings to fossil-fuel based infrastructure despite the low-emission alternatives available that could be deployed. One example of a carbon lock-in project would be an upgrade to improve the efficiency of coal-fired power plants.
Financing challenges
Climate adaptation is a much more complicated affair to track. Each activity has its own context and characteristics, and a lot of time, effort and resources are needed to monitor adaptation activities to judge whether they are "successful" or not.
CFNT attempts to address this challenge by using the Tailwind Taxonomy, a publicly available model to audit the performance of climate adaptation and resilience projects. The model was developed by Tailwind Futures, a strategic venture fund.
We chose climate adaptation projects that address the specific vulnerabilities to climate change and climate-related risk, and make assessments from the evidence-based outcomes of these activities.
What have we found?
From tallying over 2,800 project-level and organisation-level data carried out from year 2018 to May of this year, we conclude that at least 1.7 trillion baht has been invested in climate mitigation projects.
Some 82% of this sum derives from corporations, commercial banks, and state-owned enterprises. In terms of contributions by sector, 64% of total investment comes from energy and transport. Zooming into sub-sectors, the most popular climate mitigation activities are rooftop solar installations (17% of the total), electric vehicles (10%), and mass transit and mass railway projects (8%).
We also look into climate adaptation activities and projects. Based on data from 670 projects, we estimate that during 2020-2024, Thailand spent 148 billion baht on climate adaptation projects. Some 95% of the money came from Thailand's central government, followed by multilateral climate funds (1.8%). Zooming into sectors, sustainable water management, urban resilience, and sustainable agriculture are key focal areas for climate adaptation.
Those who are interested in perusing our Tracker -- reading our detailed methodology and downloading slides featuring our key highlights -- can do so by visiting our website at www.climatefinancethai.com/tracker.
By making the Tracker publicly accessible and updating the database annually, we hope to assist policymakers in identifying the gap between existing climate finance flows and demands. We seek to jumpstart conversations on climate finance, as well as enabling better allocation of funds into the most urgently needed sectors and sub-sectors in Thailand, especially to those that are the most vulnerable to the worsening impacts of climate change.

Thailand's PTTEP buys full control of offshore gas block
SINGAPORE - PTT Exploration and Production (PTTEP) of Thailand has acquired full ownership of an offshore oil block in the Gulf of Thailand in a $450-million transaction with units of US-based Chevron. The deal for Block A-18 in the Malaysia–Thailand Joint Development Area (MTJDA) was signed with Hess (Bahamas) and Hess Asia Holdings, both now owned by Chevron following a recent merger with Hess Corp, PTTEP said in a statement. The acquisition gives PTTEP 100% of the outstanding shares in Hess International Oil Corp, which holds a 50% participating interest in Block A-18, the exploration arm of PTT Plc said. The deal comes as Chevron restructures globally to streamline operations and reduce costs, a process that could involve laying off 20% of its workforce by the end of next year. Chevron is also seeking buyers for its 50% stake in its Singapore refinery, Reuters reported in June. PTTEP said natural gas from Block A-18 is fundamental to power generation for southern Thailand. The block produces about 600 million standard cubic feet of gas per day, which is equally distributed to Thailand and Malaysia. 'PTTEP is pleased to further expand our operations in the MTJDA, which is recognised for its petroleum potential and strategic significance to Thailand's energy security,' chief executive officer Montri Rawanchaikul said in the statement. The MTJDA covers 7,250 square kilometres in the southern part of the Gulf of Thailand and is a key source of natural gas and condensate for Thailand and Malaysia, according to the statement.

All eyes on Trump's August 1 deadline
As global markets continue to digest US President Donald Trump's latest trade announcements, attention now turns to the rapidly approaching Aug 1 deadline that could reshape Southeast Asia's economic landscape. While recent bilateral deals have provided some clarity, Thailand faces the dual challenge of securing favourable trade terms with the US while managing an unexpected military escalation with Cambodia. Trump's tariff template The MSCI World Index of equities has continued its upward trajectory following Trump's announcement of new trade agreements that appear to establish a regional framework. Japan secured a 15% tariff rate (down from 24%), while the Philippines and Indonesia both achieved 19% rates, down from 20% and 32% respectively. These developments, combined with Vietnam's earlier 20% agreement, suggest Southeast Asian nations may face similar tariff levels. The US-Japan deal, which Trump dubbed "the largest trade deal in history", reveals the administration's negotiating blueprint. Japan's commitment to establish a $550-billion US investment fund, alongside promises to purchase 100 Boeing aircraft and billions of dollars' worth of defence equipment annually, demonstrates the scale of concessions required to secure preferential rates. However, the agreement has drawn sharp criticism from US automotive manufacturers, who argue that reducing tariffs on Japanese cars fails to address the core trade imbalance while disadvantaging American producers. With automobiles and auto parts comprising 80% of the US-Japan trade gap, industry representatives question whether the deal serves American interests. EU prepares for trade war Meanwhile, the European Union is preparing its most powerful trade retaliation tool -- the Anti-Coercion Instrument -- should Trump proceed with 30% tariffs on European goods. The EU outlined counter-tariffs on $117 billion worth of American products, including Boeing aircraft, automobiles and bourbon whiskey, signalling that trade tensions could escalate beyond Asia. European officials have indicated a willingness to accept 15% tariffs on most goods, while negotiating to keep rates on steel and aluminium at current levels, though these products may still face 50% duties. AI and monetary policy Adding to the complex global landscape, Trump signed executive orders launching his "AI Action Plan", aimed at maintaining American technological leadership through deregulation and energy infrastructure expansion. The plan emphasises federal standardisation over state-by-state regulation, while strengthening export controls to counter Chinese artificial intelligence development. On monetary policy, Trump's unprecedented visit on Thursday to the Federal Reserve -- the first presidential visit in nearly two decades -- highlighted ongoing tensions with chairman Jerome Powell over both interest rate policy and the central bank's building renovation costs. Despite public disagreements, Trump indicated he would not remove Powell over cost overruns, while continuing to pressure for rate cuts. Precarious position For Thailand, the stakes could not be higher. Without a successful trade negotiation with the US, the kingdom faces a punitive 36% tariff rate -- among the highest proposed -- creating a significant competitive disadvantage against regional peers. This cost differential of 10 to 16 percentage points compared with Vietnam (20%) and Malaysia (25%) could prompt foreign investors to relocate production bases. Finance Minister Pichai Chunhavajira's confidence in securing competitive rates reflects the urgency of Thailand's situation. The country may need to consider sacrificing protection for certain sectors to achieve an agreement that benefits the broader economy. Cambodian conflict Thailand's trade negotiations have been complicated by an unexpected military confrontation with Cambodia. Following a Cambodian artillery attack on Thai territory, Thailand responded by deploying F-16 fighter jets to strike Cambodian firing positions, leading to a temporary 0.58% decline in the SET index. While the immediate market impact appears limited -- Cambodia represents only 3% of Thailand's total exports -- the conflict could affect specific industries dependent on the Cambodian market, particularly energy products and consumer goods including beverages and fertilisers. For Cambodia, the economic consequences are far more severe, with potential losses including worker remittances worth 6.6% of GDP and shortages of essential goods including refined oil, fertilisers and food products. Market implications InnovestX analysis suggests limited impact on major Thai stocks, as most SET50/SET100 companies have minimal Cambodian exposure. However, stocks with significant Cambodian revenue face higher risks, including Samart Aviation Solutions (SAV) with 100% exposure, Carabao Group (CBG) at 14% and the consumer finance firm Aeon Thana Sinsap (AEONTS) with 7%. We maintain a cautious outlook, noting Thailand's structural disadvantage when it comes to trade requires urgent diplomatic resolution before the Aug 1 deadline. In the longer term, Thailand must diversify its trade relationships and accelerate free trade agreement negotiations with other regions to reduce dependence on the US market. Investment strategy In this environment of heightened volatility, investors are advised to maintain diversified portfolios across defensive stocks, government bonds, commodities including gold, and alternative assets. The Thai stock market is expected to consolidate while awaiting new catalysts and monitoring trade negotiation progress. As the Aug 1 deadline approaches, Thailand's ability to navigate both trade negotiations and regional security challenges will prove crucial for maintaining investor confidence and economic stability. The coming weeks will determine whether the kingdom can secure terms that preserve its competitive position in an increasingly fragmented global economy.

PTT to sell stake in Taiwan pharmaceuticals firm
National oil and gas conglomerate PTT Plc has decided to adjust its investment in the life science business by selling a small portion of the shares it holds in Taiwan-based Lotus Pharmaceutical to boost financial flexibility. The proportion of the company shares listed on the Taiwan Stock Exchange to be sold will not exceed 2%. PTT owns a 37% stake in Lotus Pharmaceutical, said Pattaralada Sa-ngasang, chief financial officer of PTT. The completion date of the share sale has been set for July 2026. PTT holds shares in Lotus Pharmaceutical through its wholly-owned subsidiary Innobic (Asia), which operates life science-related businesses. "After this transaction in Lotus Pharmaceutical, Innobic will continue to be a major shareholder with a stake of no less than 36%," said Ms Pattaralada. "Innobic is still fully confident in Lotus Pharmaceutical's future growth." More financial flexibility after the share sale would allow PTT to drive future expansion in the life science sector, she said. The latest investment adjustment in Lotus Pharmaceutical is part of the company's revision of its life science business direction in alignment with evolving market conditions and the competitive landscape with the objective of enabling the pharmaceutical business to pursue self-funding growth, while also creating long-term benefits to PTT and Thailand. "We see a positive sentiment from special profit from the adjustment of the Lotus investment value before tax of roughly 6.2-7.6 billion baht which will be recorded in the third quarter," said Sornchai Pitthayaprug, a fundamental investment analyst on securities. "PTT will not lose control over the Lotus business and the support of profit of approximately 1.8 billion baht a year." Lotus Pharmaceutical, a listed manufacturer in Taiwan, is a distributor of medical drugs in South Korea and the US. Both Innobic and Lotus Pharmaceutical share a goal of developing the generic drug business in Southeast Asia to strengthen public health in the region. Lotus Pharmaceutical wants to focus on the treatment of non-communicable diseases (NCDs). Many countries in Asia have become ageing societies, leading to more demand for NCD medicines, Buranin Rattanasombat, chairman of Innobic (Asia), said earlier.
