6 terms

un sustainable development goals regulatory

"TransAlta aligns its corporate goals with the UN Sustainable Development Goals and the Future-Fit..."

The UN Sustainable Development Goals are a set of 17 global targets created to guide governments, businesses and organizations toward ending poverty, protecting the planet and promoting fair prosperity. Investors pay attention because these goals influence future regulations, consumer preferences and long-term risks and opportunities—like choosing durable practices that protect returns—so companies aligned with them may face fewer surprises and better long-term prospects, similar to choosing a well-built ship for a long voyage.

future-fit business benchmark technical

"TransAlta aligns its corporate goals with the UN Sustainable Development Goals and the Future-Fit Business Benchmark..."

A future-fit business benchmark is a clear set of criteria used to judge whether a company is prepared for long-term challenges like climate change, resource limits, regulation, and technological shifts. Think of it as a practical checklist that rates how well a business can adapt and keep delivering profits; investors use it to compare resilience, spot risks that could hurt future returns, and prioritize capital toward companies more likely to thrive.

ifrs s2 climate-related disclosures standard regulatory

"reporting on climate change management has been guided by the International Financial Reporting Standards (IFRS) S2 Climate-related Disclosures Standard..."

A global reporting standard that tells companies what climate-related information to disclose so investors can compare risks and plans across firms. Think of it as a consistent checklist and roadmap for reporting how a business is exposed to physical climate impacts and to rules or market shifts from the transition to a low-carbon economy. Investors use these disclosures to assess potential future costs, opportunities, and how well a company is prepared for climate-related shocks.

task force on climate-related financial disclosures (tcfd) regulatory

"and the Task Force on Climate-related Financial Disclosures (TCFD) recommendations."

A set of recommended disclosures on how climate change creates financial risks and opportunities for a company, covering governance, strategy, risk management and metrics. Think of it like a standardized inspection report that helps investors compare how well different companies identify and prepare for climate-related threats and chances; clearer, consistent reporting makes it easier to assess long-term risk, value and where to put capital.

msci esg rating technical

"and received an upgraded MSCI ESG rating of AA."

An MSCI ESG Rating is a standardized score that evaluates a company’s exposure to environmental, social and governance risks and how well it manages them compared with peers. Investors use it like a credit score for non-financial risks—helping judge whether a firm is likely to face reputational, regulatory or operational problems that could hurt returns over time, and to align portfolios with sustainability goals.

co2e technical

"TransAlta has achieved a 70 per cent reduction in GHG emissions or 22.7 million tonnes CO2e since 2015..."

CO2e is a single number that expresses the warming effect of all greenhouse gases as the amount of carbon dioxide they would equal, so different gases can be compared on the same scale. Think of it like converting different currencies into dollars to make an apples-to-apples comparison. Investors use CO2e to gauge a company’s climate impact, regulatory and carbon‑pricing exposure, and potential costs or reputational risks tied to emissions.
