FY21 ESG Disclosures July 2022 Unaudited 7 ENVIRONMENTAL ENV.1 Introduction As a recognized global leader in environmental and sustainability professional services, Jacobs holds environmental protection as a core value, as expressed in the Jacobs Global Environmental Management Commitment Statement and as the cornerstone of our PlanBeyond ℠ Sustainability and BeyondZero ℠ Health, Safety and Environment (HSE) approaches. Our Office of Global Climate Response & ESG was established in October 2021 and reports to our President and Chief Operations Officer (COO), Bob Pragada. The office acts as a connecting point for Jacobs’ go-to-market solutions within the framework of energy transition, decarbonization, adaptation and resilience, and natural resource stewardship, along with ESG advisory. Globally, in FY20 and FY21 we achieved 100% renewable electricity for our operations and carbon neutrality for our operations and business travel, as further described under ENV.3 Greenhouse Gas Emissions . We are committed to continuing these achievements. ENV.2 Environmental Reporting We report on environmental issues and Key Performance Indicators (KPIs) in the public domain and provide targets linked to these indicators. All environmental indicators reported in this document, unless otherwise noted, cover 100% of Jacobs’ business locations. Carbon emissions were third-party verified with limited assurance for all years reported. Other relevant information is available in our Integrated Annual Report, PlanBeyond 2.0 sustainable business approach, and Environmental Performance Reports for locations certified to ISO14001. ENV.3 Greenhouse Gas Emissions Our deep commitment to environmental protection and concern regarding the climate crisis led to aggressive carbon emission commitments that are set forth in our Climate Action Plan , first published on April 22, 2020. Detailed in our Carbon Neutrality Commitment included in the Climate Action Plan, we achieved 100% low-carbon electricity and became carbon neutral for our operations and business travel in 2020 and continue to maintain these commitments. Joining over 300 companies worldwide in November 2020, Jacobs became a signatory to the U.N. Business Ambition for 1.5°C , an urgent request for action from the global coalition of U.N. agencies, business and industry leaders, calling on businesses to set ambitious science-based emissions reduction targets aligned with limiting global temperature rise to 1.5°C above pre-industrial levels. Our 2020 climate commitments were a major milestone in our drive to address the climate crisis. In keeping with our core value of “We Aim Higher” and the continually evolving guidance and best practices for climate response, we revised our plan and targets. In our updated Climate Action Plan , published in April 2022, we commit to the following: 1. Ensure every project becomes a climate response opportunity. 2. Achieve net-zero greenhouse gas emissions across the value chain by 2040. 3. Maintain carbon neutrality status and 100% low-carbon electricity for our operations. As a member of the Science Based Target initiative (SBTi) Technical Advisory Group (TAG) since 2020 and a participant in the Net-Zero Road Test in 2021, we committed to setting net-zero targets in line with the SBTi Corporate Net-Zero Standard. Key requirements of the Net-Zero Standard include focusing on rapid, deep emissions cuts; setting near- and long-term targets; claiming achievement of net zero only after long-term targets are met; and investing in mitigation within and outside the value chain.
