Pella applies Negative Screens at the start of the research process. It identifies these companies using its own fundamental analysis, supplemented with research from external research providers. Companies generating any revenue from activities related to animal cruelty, such as cosmetic testing, crowd entertainment, and intensive animal husbandry, correctional facilities, deforestation, GMO seeds manufacturing, pornography, uranium mining, and manufacturing of alcoholic beverages are excluded from Pella's investment universe. Pella excludes companies that generate revenue from thermal coal power generation, that have any direct exposure to fossil fuel exploration, and companies that generate more than 15% of their revenue from gas-fired generation.

It excludes enterprises that generate any revenue from direct exposure to slot machines, casino operations (online and/or physical), lotteries, sports/other betting, companies that generate any revenue from selling or distributing such weapons or weapon delivery systems, and all companies involved in the production of tobacco and companies with significant ownership (due to holding directly, more than 10% of shares) in such companies. Norms-based screens applied by Pella involve identifying and excluding companies that do not meet minimum standards of business practices based on international norms and conventions, primarily based on the UN Global Compact (UNGC).

Pella incorporates ESG considerations throughout its investment process. This is delivered using internal analysis, MSCI and Refinitiv ESG ratings, and assessing controversies. The common ESG issues Pella considers relate to the Environment, such as climate change, sustainability, biodiversity and water, pollution and waste. Social issues, such as human capital, product liability, human rights, community standards, and Governance related issues, such as management structure, compliance, board accountability, transparency, corruption, and tax strategy. 

Pella has identified six themes that generate positive outcomes for current or future generations at no cost to current or future generations. These themes relate to several SDG targets that are dynamic and could expand as new opportunities arise. Pella targets portfolio CO2 intensity to be at least 30% below the Benchmark with CO2 intensity measured using Scope 1 and Scope 2 carbon emissions relative to revenue as calculated by Refinitiv.

Investment Stewardship considerations and behaviours are incorporated by Pella into all the investments made by the funds it manages. It applies four primary tools to fulfil its Investment Stewardship responsibilities, including engagement, voting, advocacy, and transparency.

Pella became a signatory to the UN Global Compact and Principles for Responsible Investment in 2022 aligning with their principles. Pella's weapons exclusion policy, encompassing weapons and delivery systems compliant with weapon treaties, adheres to both the Convention on Cluster Munitions and the Ottawa Convention on Land Mines. Additionally, it integrates the UN Guiding Principles on Business & Human Rights into their practices. Regarding climate action, Pella focuses on the major source of GHG, namely CO2, and the largest emitters of CO2. It also considers the OECD Guidelines for Multinational Enterprises. Lastly, Pella aims to maximise positive impacts by aligning corporate activities with their Positive Impact Themes, in line with the Sustainable Development Goals.
