Environmental, Social and Governance (ESG)

Environmental, social and governance (ESG) is a scoring framework that rates a firm’s climate impact, labor practices and board conduct. ESG data now guides capital allocation, and global fund managers screen equity, credit and property assets across the three pillars.

ESG entered mainstream investing after the 2004 UN report Who Cares Wins. Sustainable AUM surpassed $30 trillion by 2022 per Global Sustainable Investment Alliance data, though 2023 saw a correction amid US political pushback.

For outsourcing buyers, ESG matters because a provider’s carbon disclosures, wage practices and data governance now flow into the client’s own reporting under regulations like the EU Corporate Sustainability Reporting Directive.

The three pillars aren’t equally weighted. Governance often leads because weak boards produce weaker environmental and social outcomes downstream. Rating agencies cite governance as most correlated with long-term shareholder returns.

Key takeaways

• ESG evaluates three linked pillars: environmental impact, social responsibility and governance structure, together inside one company scorecard used by investors and regulators.
• Roughly $30 trillion in assets under management screened against ESG criteria as of 2022 per Global Sustainable Investment Alliance data, a figure that has plateaued through 2024.
• Regulations like the EU CSRD and the SEC’s 2024 climate rule push ESG reporting duties down the outsourced supply chain, so BPO providers now field client audits routinely.
• Established frameworks such as SASB, GRI, TCFD and the UN Principles for Responsible Investment set the disclosure vocabulary companies actually report against.

How it works

ESG works as a three-pillar scorecard. Investors and rating agencies score companies on environmental impact, social responsibility and governance quality, then feed the composite into portfolio construction, lending and procurement decisions.

Each pillar carries its own metric set. Environmental covers greenhouse-gas emissions, water use and waste. Social spans labor rights, diversity and community impact.

Governance tracks board independence, executive pay and anti-corruption controls — often the pillar where BPO clients focus first when vetting a provider’s compliance posture.

Ratings differ by provider. MSCI uses AAA-CCC letters, Sustainalytics runs a 0-100 risk score, and S&P Global bases its rating on Corporate Sustainability Assessment surveys. A single company can hold three different ESG ratings in the same quarter.

MSCI’s methodology also weights industry-relevant issues higher, so a utility gets scored heavily on emissions and a bank on cybersecurity. Two firms in the same index therefore rarely draw the same profile even when their headline scores match.

Reporting frameworks anchor the numbers. The SASB Standards, now under the IFRS Foundation, map material issues by industry. TCFD covers climate risk while GRI covers broader stakeholder impact.

Assurance is optional but rising. Deloitte reported in 2024 that 71% of large listed firms now get some ESG data externally assured, up from 51% in 2019. Auditor sign-off narrows the credibility gap that skeptics highlight.

Data quality remains uneven. Reported figures often mix audited financial data with self-reported climate estimates, and disclosure lag can stretch to 18 months. Rating agencies close the gap through modelled estimates and industry benchmarks.

Reporting cadence has hardened around annual sustainability reports filed alongside 10-Ks and 20-Fs. The SEC’s 2024 climate disclosure rule and the EU’s CSRD both push toward mandatory quarterly climate updates for the largest reporters.

Examples

ESG plays out differently across sectors. Below are four cases — one from apparel, one from tech services, one from banking and one from BPO — where ESG scores drove either investment inflows, procurement wins or a sharp market repricing between 2020 and 2024.

Patagonia (2022): the outdoor apparel brand transferred ownership to a climate trust when founder Yvon Chouinard redirected all future profits to environmental protection. The move cemented its ESG leadership tier and drew capital from purpose-mandate funds.

Accenture (2023): the consultancy pledged net-zero by 2025 and tied executive bonuses to progress on the target. Rating agencies used that governance move to lift its ESG scores across MSCI and Sustainalytics.

HSBC (2022): the UK bank suspended its head of responsible investing after he publicly called climate risk overhyped. Sustainalytics dropped the bank’s governance sub-score within 90 days of the incident.

Concentrix (2023): the customer experience BPO published its first TCFD-aligned climate report, moving into the ESG-disclosure tier that Fortune 500 buyers increasingly require in RFPs for outsourced contact-center work.

Together the four cases show ESG-linked outcomes reward specific actions like leadership commitment, disclosure discipline and executive-pay linkages, rather than broad brand statements about sustainability. Investors verify the mechanics before revaluing the multiple.

FAQ

What are the three pillars of ESG?

Environmental covers climate impact, resource use and pollution. Social covers labor rights, diversity and community relations. Governance covers board structure, executive pay and anti-corruption controls.

Who uses ESG scores?

Asset managers use ESG data for portfolio construction, banks use it for lending decisions and corporate procurement teams use it to vet suppliers, including outsourcing providers.

Is ESG the same as sustainability?

No, sustainability is the broader environmental and social goal, while ESG is the measurable investment-grade framework used to score companies on those goals plus governance quality.

How does ESG affect outsourcing contracts?

Buyers increasingly ask for supplier ESG disclosures in RFPs, and many now require CSRD-aligned reporting or an SASB scorecard before signing multi-year deals.
