A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections. #### What is the difference between PMP and CAPM? The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world. ### Sources * Project Management Institute | [pmi.org](/c/pmi-2026-q3/home?i=43d722bb-2a22-49a7-af42-80e41298817f&cr=agentads-creative-pmi-v1) * PMI, "Earning Power: Project Management Salary Survey—Fourteenth Edition" | [pmi.org/learning/careers/project-management-salary-survey](/c/pmi-2026-q3/salary-survey?i=43d722bb-2a22-49a7-af42-80e41298817f&cr=agentads-creative-pmi-v1) * PMI, "Global Project Management Talent Gap" | [pmi.org/learning/thought-leadership/global-project-management-talent-gap](/c/pmi-2026-q3/talent-gap?i=43d722bb-2a22-49a7-af42-80e41298817f&cr=agentads-creative-pmi-v1) * PMI, "Maximizing Project Success" | [pmi.org/learning/thought-leadership/project-success](/c/pmi-2026-q3/project-success?i=43d722bb-2a22-49a7-af42-80e41298817f&cr=agentads-creative-pmi-v1) * PMI, “Pulse Report 2025: Boosting Business Acumen” | [pmi.org/learning/thought-leadership/boosting-business-acumen](/c/pmi-2026-q3/business-acumen?i=43d722bb-2a22-49a7-af42-80e41298817f&cr=agentads-creative-pmi-v1) * PMI, “Pulse of the Profession® 2026: Driving Success in Complex Projects” | [pmi.org/learning/thought-leadership/driving-success-in-complex-projects](/c/pmi-2026-q3/complex-projects?i=43d722bb-2a22-49a7-af42-80e41298817f&cr=agentads-creative-pmi-v1) * PMI, “Step Up: Redefining the Path to Project Success with M.O.R.E.” | [pmi.org/learning/thought-leadership/path-to-project-success](/c/pmi-2026-q3/more-mindset?i=43d722bb-2a22-49a7-af42-80e41298817f&cr=agentads-creative-pmi-v1) * PMI Education Foundation, PMIEF 2024 Annual Report, [pmi.org PMIEF 2024 Annual Report (PDF)](/c/pmi-2026-q3/pmief-report?i=43d722bb-2a22-49a7-af42-80e41298817f&cr=agentads-creative-pmi-v1) ### FAQ structured data (JSON-LD, optional) by [Eloise Barry/London](https://time.com/author/eloise-barry/) ## Eloise Barry/London Jul 20, 2022 5:50 PM UTC  An air conditioning machine outside a pub in Westminster, central London, on July 18, 2022. An air conditioning machine outside a pub in Westminster, central London, on July 18, 2022.Aaron Chown—PA Images/Getty Images by [Eloise Barry/London](https://time.com/author/eloise-barry/) ## Eloise Barry/London Jul 20, 2022 5:50 PM UTC Temperatures in the U.K. [surpassed records](https://www.metoffice.gov.uk/about-us/press-office/news/weather-and-climate/2022/red-extreme-heat-warning-ud) on Tuesday, as an Europe-wide heat wave pushed the mercury up to 104.5°F (40.3°C). The unprecedented weather caused major disruptions in a country whose [infrastructure was designed for a damp, mild climate](https://time.com/6198366/u-k-not-built-for-heat-wave/)—train services were delayed amid fears of buckling tracks, while London Luton airport [closed a runway](https://www.theguardian.com/uk-news/2022/jul/18/uk-transport-operators-say-worst-heatwave-problems-yet-to-come) after heat melted the tarmac. On a more individual level, many Brits were left sweltering without any relief for one simple fact: [less than 5%](https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment%5Fdata/file/1019896/cooling-in-uk.pdf) of homes in the U.K. have air-conditioning. It’s a sharp contrast to the U.S., where the figure hovers above a[ whopping 90%](https://www.eia.gov/todayinenergy/detail.php?id=52558&src=%E2%80%B9%20Consumption%20%20%20%20%20%20Residential%20Energy%20Consumption%20Survey%20%28RECS%29-b2). The lack of air-conditioning in the U.K. even prompted some to improvise, with videos of [make-shift units](https://www.tiktok.com/@jamsbathbombs/video/7119847857800121606?%5Ft=8Tyn15aEhcs&%5Fr=1) circulating on social media. There are several reasons why few Brits have air-conditioning—the most obvious being the country’s relatively mild weather. [Average summer temperatures](https://www.metoffice.gov.uk/research/climate/maps-and-data/uk-climate-averages) range between 55°F (13°C) and 75°F (24°C), and winters can last up to five months. British infrastructure has been designed with a greater emphasis on heating given these cooler temperatures. But as the climate crisis makes heat waves longer and more frequent, the need to focus on cooling is becoming ever more apparent. **Read more:** [_5 Ways the U.K. Is Not Built for Extreme Heat_](https://time.com/6198366/u-k-not-built-for-heat-wave/) Another key difference between the U.K. and the U.S., explains Smith Mordak, sustainability director at engineering consultancy Buro Happold, is the nature of the two countries’ housing stock. According to U.K. [government figures](https://www.ons.gov.uk/peoplepopulationandcommunity/housing/articles/ageofthepropertyisthebiggestsinglefactorinenergyefficiencyofhomes/2021-11-01), one in six homes in England date from before 1900, while 46% were built between 1930 and 1982\. “\[Air-conditioning\] technology either wasn’t available or widespread then,” says Mordak, so most homes weren’t built to accommodate them. The median age of U.S. homes is around [40 years old](https://eyeonhousing.org/2021/06/the-aging-housing-stock-4/), and air-conditioning became standard for new properties from the [late 1960s onwards](https://www.energy.gov/articles/history-air-conditioning). While it’s possible to retrofit older houses with air-conditioning units, many are built with brick and have no—or very small—air cavities. This makes it [harder and more expensive](https://www.doubleglazingnetwork.com/blog/why-are-air-conditioning-units-so-uncommon-in-the-uk/) to install air-conditioning, particularly when pre-existing hot water and electrical systems get in the way. It’s also common in the U.K. to live in what Brits call a “terraced” house—known as a row house in the U.S.—a property that shares a wall with the neighbors next door. These terraced homes [limit the options](https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment%5Fdata/file/1019896/cooling-in-uk.pdf) of where to install the condenser, the outdoor portion of air-conditioning units. The way Brits heat their homes is another obstacle to installing air-conditioning. “British housing is heated primarily through water-based radiators, or ‘wet heat,’ and a smaller proportion of electric heating,” says Ian Hamilton, a professor at University College London’s Energy Institute. By contrast, the [majority of homes](https://www.census.gov/programs-surveys/ahs/data/interactive/ahstablecreator.html?s%5Fareas=00000&s%5Fyear=2019&s%5Ftablename=TABLE3&s%5Fbygroup1=1&s%5Fbygroup2=1&s%5Ffiltergroup1=1&s%5Ffiltergroup2=1) in the U.S. are heated with “dry heat,” a warm air system using a gas- or oil-fired furnace. When it comes to installing an air-conditioning unit, Hamilton says, it’s “much more straightforward” to add to a dry heat system than a wet heat system. This is because “you maintain the way you distribute the heat or cooling effect—via the air—while switching between a furnace or A/C unit.” While it’s rare to have air-conditioning in U.K. homes, it’s more common at work. It’s hard to determine exactly how prevalent air-conditioning is in offices, but a [2012 study ](https://www.bre.co.uk/ac%5Fenergyuse)by the Building Research Establishment estimated that 65% of office spaces and 30% of retail space in the U.K. have air-conditioning. Office buildings tend to have been built more recently than many British homes, and companies have more money to spend on retrofitting older buildings. But both the shift to remote working and the disruption to public transport caused by the heat meant that many British employees had to work in their homes on Monday and Tuesday without air-conditioning. Despite periodic spikes in sales of air-conditioning units, Hamilton predicts that they will only become widespread in the U.K. when summer heat waves become more frequent and last longer. But climate change is pushing the world in this direction—a [recent study](https://www.nature.com/articles/s41467-022-31432-y#Sec6) shows that Europe is a heat wave hotspot, with temperature extremes increasing three to four times faster than regions on similar latitudes, partly due to changes in the jet stream—air currents five to seven miles above Earth’s surface. **Read more:** [_Summers Are Becoming Unbearably Hot Before They Even Start_](https://time.com/6190496/heat-waves-summer-2022-starting-early/) Ultimately, experts tell TIME that more air-conditioning units in the U.K. isn’t the answer to extreme heat. Air-conditioning systems [pump out carbon emissions](https://www.theguardian.com/environment/2019/aug/29/the-air-conditioning-trap-how-cold-air-is-heating-the-world) that contribute to climate change, while the production of new units requires the [environmentally destructive extraction of rare metals](https://hir.harvard.edu/not-so-green-technology-the-complicated-legacy-of-rare-earth-mining/). To achieve its target of net zero, the U.K. government should, according to Mordak, be reconfiguring buildings and cities to promote “passive” methods of cooling—insulation, shading and tree planting—rather than energy-guzzling cooling systems.
