CTCI Achieves Top 1% Ranking in Sustainability Yearbook
Taiwanese EPC firm scores 86 out of 100 in global assessment
CTCI Corporation has secured a place in the top 1% of companies worldwide in S&P Global’s 2026 Sustainability Yearbook. This marks the fourth consecutive year the Taiwanese engineering, procurement, and construction firm has earned this distinction. The company achieved the highest score among all construction and engineering businesses assessed globally.

The recognition reflects sustained performance across environmental, social, and governance criteria. For UK businesses working with international contractors or monitoring supply chain sustainability, this sets a benchmark for what advanced ESG performance looks like in practice.
S&P Global’s Corporate Sustainability Assessment scored CTCI at 86 out of 100 in 2024. This places the firm at the top of its sector for the third consecutive year. The assessment evaluates companies on their environmental impact, social policies, and governance structures. It provides investors and clients with comparable data on corporate sustainability performance.
More than 9,000 companies assessed worldwide
The 2026 Sustainability Yearbook evaluated over 9,200 companies across 62 industries. Only 848 achieved Yearbook membership. This represents a selection rate of approximately 9%, demonstrating the rigour of the assessment process.
Companies are scored based on their performance in the previous calendar year. The assessment examines material issues specific to each industry. For construction and engineering firms, this typically includes carbon emissions from projects, worker safety, supply chain management, and business ethics.
CTCI’s score of 86 positions it significantly above industry averages. The company maintained its top-tier ranking despite increasing assessment standards. This suggests genuine progress rather than static compliance.
Science-based targets approved for 1.5°C pathway
CTCI has committed to emissions reduction targets validated by the Science Based Targets initiative. These targets align with limiting global temperature rise to 1.5°C above pre-industrial levels. This represents the more ambitious goal within the Paris Agreement framework.
The company aims to reduce emissions by 45% by 2030, measured against a 2022 baseline. It has also committed to achieving net zero emissions by 2050. These targets cover operational emissions and, critically, project-related impacts.
For businesses evaluating contractors, SBTi-approved targets provide independent verification of climate commitments. The initiative assesses whether reduction plans align with climate science. This offers more certainty than unverified corporate pledges.
CTCI has also set nature-related targets. The company commits to no net loss in biodiversity protection by 2030 across operation sites. It aims for zero deforestation across these sites by the same date. By 2050, CTCI targets a net positive impact on biodiversity across all operations.
Early adoption of nature-related financial disclosures
CTCI is an early adopter of the Taskforce on Nature-related Financial Disclosures framework. TNFD provides a structure for organizations to report on nature-related dependencies, impacts, risks, and opportunities. This framework launched in September 2023.
Early adoption signals that a company is monitoring biodiversity risks before regulatory requirements emerge. For engineering firms, this matters because projects can have significant local environmental impacts. Understanding these risks helps businesses manage planning permissions, community relations, and regulatory compliance.
The company states it delivers green engineering projects that help clients reduce energy consumption and carbon emissions. This approach attempts to balance environmental protection with economic viability. However, the specifics of how projects achieve these reductions are not detailed in public disclosures.
Decade of recognition in emerging markets indices
CTCI has ranked in the top 1% for the Dow Jones Sustainability Emerging Markets Index for ten consecutive years. This index tracks sustainability performance among companies in emerging market economies. It includes firms from countries like Taiwan, South Korea, Brazil, and India.
The company has also achieved the highest score among construction and engineering peers in the global DJSI for three consecutive years. This positions CTCI above competitors in both developed and emerging markets.
In 2024, CTCI received multiple regional awards. These included Gold in the Taiwan Biodiversity Awards as part of the Taiwan Corporate Sustainability Awards. The company also earned Gold ratings in the Asia-Pacific Sustainability Action Awards for Climate Action and Water and Sanitation categories.
CTCI has received the CommonWealth Magazine Corporate Social Responsibility Award for 16 consecutive years. This Taiwanese publication focuses on business and economic issues. The consistency of recognition suggests sustained rather than sporadic effort.

What this means for UK supply chains and procurement
For UK businesses managing international supply chains, CTCI’s performance illustrates the ESG standards now expected from major contractors. Procurement teams increasingly face requirements to verify supplier sustainability credentials. This applies particularly to public sector contracts under regulations like Procurement Policy Note 06/21.
Third-party assessments like S&P Global’s CSA provide independent verification of ESG claims. This matters because corporate sustainability reports vary widely in quality and comparability. Standardized scores allow procurement teams to compare suppliers objectively.
Companies with SBTi-approved targets have had their climate commitments validated against scientific benchmarks. This reduces the risk of working with suppliers making unsubstantiated claims. For businesses reporting their own Scope 3 emissions, supplier data quality becomes increasingly important.
The inclusion of biodiversity targets reflects growing recognition of nature-related risks. UK businesses will face new disclosure requirements under the Taskforce on Nature-related Financial Disclosures as it becomes more widely adopted. Understanding how leading firms approach these issues can inform your own reporting strategies.
Engineering and construction firms face particular scrutiny due to the environmental impact of infrastructure projects. Site biodiversity, resource consumption, and local pollution are material issues. Contractors with established environmental management systems and verified targets present lower reputational and compliance risks.
However, high sustainability scores do not guarantee project delivery, quality, or commercial terms. ESG performance forms one component of supplier evaluation. It should be weighted alongside technical capability, financial stability, and track record.
For businesses developing their own sustainability strategies, examining peer performance provides context. CTCI’s recognition demonstrates what advanced ESG management looks like in the construction and engineering sector. This can help you benchmark your own programs and identify areas for improvement.
If your business is working towards carbon reporting compliance requirements, understanding how suppliers manage their emissions becomes part of your own reporting. Supply chain emissions typically represent the largest component of a company’s carbon footprint. Supplier engagement on climate targets is therefore a practical necessity, not just a matter of corporate responsibility.
Tracking performance against climate science
The Science Based Targets initiative provides independent validation of corporate climate commitments. Targets are assessed to determine whether they align with pathways that limit warming to 1.5°C or well below 2°C. This offers more credibility than internally defined reduction goals.
For a target to be approved, companies must demonstrate how they will achieve stated reductions. The methodology varies by sector, reflecting different decarbonization challenges. Construction and engineering firms must typically address both operational emissions and those from delivered projects.
CTCI’s 45% reduction target by 2030 aligns with the pace of change required under a 1.5°C scenario. This is more ambitious than a 2°C pathway, which would require slower near-term reductions. The distinction matters because the impacts of climate change accelerate significantly above 1.5°C of warming.
Net zero by 2050 has become a common long-term target. However, the credibility of such commitments depends on near-term action. The 2030 interim target provides a more immediate test of whether reduction plans are being implemented effectively.
For UK businesses, supplier climate targets affect your own Scope 3 reporting. Scope 3 covers indirect emissions from your value chain, including purchased goods and services. If your suppliers have credible reduction plans, this supports your own reported trajectory.
Businesses participating in net zero programs will increasingly need to demonstrate supply chain engagement. This includes understanding supplier emissions, encouraging target-setting, and preferencing low-carbon options where feasible. Tracking supplier progress through frameworks like SBTi provides structure to this process.
Sustainability indices and investment decisions
The Dow Jones Sustainability Indices track companies based on economic, environmental, and social criteria. Inclusion in these indices affects investment flows, as many funds screen for or preferentially weight high-scoring companies. This creates a financial incentive for strong ESG performance.
CTCI’s ten-year presence in the DJSI Emerging Markets Index indicates sustained performance rather than short-term achievement. Indices rebalance regularly, removing companies that slip below threshold scores. Maintaining inclusion requires ongoing effort and improvement.
For UK businesses, sustainability indices matter because they influence the cost and availability of capital. Companies with strong ESG ratings typically access funding at better rates. They also attract investment from funds with sustainability mandates.
Public procurement increasingly incorporates sustainability criteria into tender evaluation. Suppliers with verified ESG credentials may score higher in non-price factors. This creates commercial advantages beyond investor relations.
The trend towards standardized ESG reporting continues to develop. UK businesses should expect growing requirements to disclose environmental and social performance through comparable frameworks. Understanding how assessment systems work helps you prepare for these obligations.
